DHS's spending on services—such as guard services and technology support—represents over 75 percent of its annual contract obligations. The Office of Management and Budget has recognized that some service contracts require extra management attention because they pose a risk that the government could lose control of its decisions or operations. GAO was asked to review DHS's use of and planning for service contracts. This report addresses, among other objectives, the extent to which DHS and selected components and offices use, oversee, and budget for service contracts. GAO analyzed Federal Procurement Data System-Next Generation data from fiscal years 2013 through 2018; selected non-generalizable samples of four components with high service contract obligations and eight service contracts requiring heightened management attention; and interviewed DHS officials. From fiscal years 2013 through 2018, the Department of Homeland Security (DHS) increased its reliance on contracts for services, particularly those in categories that may need heightened management attention, such as drafting policy documents (see figure). These services include functions that are closely associated with inherently governmental, critical, or special interest, which could put the government at risk of losing control of its mission if performed by contractors without proper oversight by government officials. GAO found that DHS and selected components do not consistently plan for the level of federal oversight needed for these contracts because there is no guidance on how to document and update the number of federal personnel needed to conduct oversight. GAO also found that program and contracting officials from six of the eight contracts GAO reviewed did not identify specific oversight activities they conducted to mitigate the risk of contractors performing functions in a way that could become inherently governmental. DHS lacks guidance on what these oversight tasks could entail. Without guidance for documenting and updating the planned federal oversight personnel needed, and identifying oversight tasks, DHS cannot mitigate the risks associated with service contracts in need of heightened management attention. Selected DHS components have information on service requirements, but budget documentation—submitted to DHS headquarters as well as to Congress—does not communicate details about most estimated or actual service contract requirements costs. Given that services account for over three-quarters of DHS's annual funding for contracts, additional insights would shed light into how much of DHS's mission is being accomplished through services, including those requiring heightened management attention. Without more visibility into this information, DHS headquarters and Congress are at risk of not having complete information for sound resource planning and decision-making, particularly as it relates to determining what proposed service contract requirements DHS should prioritize when budgeting.


DOD can declare defense equipment as excess to U.S. military needs and make it available for transfer as a grant or sale to foreign governments. The Foreign Assistance Act of 1961 authorizes these transfers as grants provided that they do not adversely affect the U.S. national technology and industrial base, among other things. In this regard, transfers pursuant to the Act must not limit U.S. companies' ability to sell new or used defense equipment to countries requesting the transfer. The 2018 NDAA generally requires that Humvee transfers be modernized with a new powertrain and armor prior to being transferred. The Act also generally requires GAO to report on proposed and completed Humvee transfers and the process to determine if transfers will adversely affect the industrial base. This report provides information on (1) excess Humvees requested and approved during fiscal years 2012 through 2018 and (2) how the Humvee manufacturer's perspectives on the proposed transfers have been addressed by DOD as part of the determination of any adverse industrial base effects. GAO analyzed the latest DOD data on EDA Humvee transfers from fiscal years 2012 through 2018; reviewed DOD policies, guidance, and documents to gain insight into the process for determining industrial base effects of proposed transfers; and interviewed agency officials and Humvee manufacturer representatives. Excess High Mobility Multipurpose Wheeled Vehicles (HMMWV)—commonly pronounced Humvees—are among thousands of items that the Department of Defense (DOD) can transfer to foreign governments at their request through the Excess Defense Articles (EDA) program. Twenty-three countries, primarily from the Middle East and Africa, requested 16,005 Humvees for the 7-year period GAO reviewed. DOD approves such requests if it determines: excess U.S. inventory is available at the time of the request, the request aligns with U.S. foreign policy objectives, such as using the vehicles to help combat terrorism, and the U.S. industrial base will not be adversely affected by the transfer. For example, DOD approved a country's request for excess Humvees for border security, counter-smuggling, and counter-terrorism efforts. DOD approved nearly half of the total Humvees requested for fiscal years 2012 through 2018 (see figure). However, DOD has halted further approvals since the start of fiscal year 2017 due to concerns expressed by the Humvee manufacturer and language in the FY 2018 National Defense Authorization Act (2018 NDAA) and conference report that generally says Humvees must be modernized at no cost to DOD. GAO found that DOD considered the Humvee manufacturer's perspectives on proposed transfers and generally took steps to mitigate concerns about transfers that could siphon potential business from the manufacturer or compete with its sales efforts. Further, GAO found that generally, when the manufacturer objected to a transfer, the manufacturer withdrew its objection after receiving business opportunities to repair or upgrade vehicles for DOD or a requesting government's fleet. DOD officials also noted that most of the countries requesting Humvees through the EDA program find it cost-prohibitive to purchase new Humvees directly from the manufacturer. As a result, these countries rely on EDA Humvees to sustain their military fleets.


DOD continues to confront organizational challenges that hinder collaboration. To address these challenges, section 911 of the NDAA for Fiscal Year 2017 directed the Secretary of Defense to, among other things, issue an organizational strategy that identifies critical objectives that span multiple functional boundaries; establish cross-functional teams to support this strategy; and provide related guidance and training. The NDAA for Fiscal Year 2017 also included a provision for GAO to assess DOD's actions in response to section 911. This report assesses the extent to which DOD has made progress in implementing the requirements of section 911, including establishing a new cross-functional team on electromagnetic spectrum operations. GAO reviewed documentation, interviewed cross-functional team members and other DOD officials, and compared DOD's actions to section 911 requirements and leading practices for cross-functional teams. The Department of Defense (DOD) is up to 21 months late in fully addressing five of seven requirements of section 911 of the National Defense Authorization Act (NDAA) for Fiscal Year 2017. These remaining five requirements are designed to strengthen collaboration within the department to foster effective and efficient achievement of objectives and outputs (see figure). DOD has not addressed most of these remaining requirements of section 911 largely because the Chief Management Officer (CMO) has not approved the documents drafted to meet the requirements or coordinated department-wide review of the documents and provided them for Secretary of Defense issuance. According to Office of the CMO (OCMO) officials, some of the draft documents were provided to the CMO for review and approval as early as August 2018. After providing a draft of this report to the department for comment, GAO learned that the organizational strategy was circulated for department coordination in July 2019, with components expected to provide input by August 2019. However, while the OCMO has set an internal time frame for the organizational strategy, it has not set similar time frames for completing the other four remaining requirements, such as delivering guidance and training on cross-functional teams. GAO previously reported that establishing internal deadlines with key milestones and deliverables is important for tracking progress and implementing actions effectively. DOD established a cross-functional team pursuant to section 911 on electromagnetic-spectrum operations (EMSO), but according to a team official, funding for the team was delayed. EMSO refers to those activities consisting of electronic warfare and joint electromagnetic-spectrum management operations used to exploit, attack, protect, and manage the electromagnetic operational environment to achieve the commander's objectives. According to the memorandum establishing the team, the CMO is required to provide administrative support to and coordinate with the team to ensure adequate resources are immediately available. However, team officials stated that this funding was delayed in part because of disagreements over responsibility for funding the team under the terms of this memorandum. Moreover, according to a team official, plans for funding in future fiscal years have not been developed. If DOD does not clarify roles and responsibilities for funding the team, the CMO and the EMSO team may face additional delays securing funding, which could negatively affect the team's ability to conduct its work and meet its objectives.


DOD contracts with private sector companies—referred to as managed care support contractors—to deliver health care services to its TRICARE program beneficiaries through networks of civilian providers. In July 2016, DOD awarded its fourth generation of TRICARE contracts, referred to as T-2017, for management of civilian providers in its two regions (East and West). For new TRICARE contracts, DOD provides a transition period—usually 9 to 12 months—for the incoming and outgoing contractors. During this time, the incoming contractors must take specific steps to prepare for health care delivery. The John S. McCain National Defense Authorization Act for Fiscal Year 2019 included a provision for GAO to review the T-2017 transition. This report examines (1) how the requirement to implement TRICARE Select affected the transition, (2) challenges DOD experienced executing the T-2017 transition process, and (3) how DOD addressed problems after the start of health care delivery. GAO reviewed and analyzed DOD guidance, contract requirements, and other relevant documentation, and interviewed DOD officials, TRICARE contractors, and other stakeholders. The implementation of a required new health care benefit option delayed aspects of the transition to the Department of Defense's (DOD) fourth generation of TRICARE managed care support contracts (T-2017). The National Defense Authorization Act for Fiscal Year 2017 required DOD to implement TRICARE Select, a new preferred provider benefit option. As a result, DOD delayed the start of health care delivery—the date the incoming T-2017 contractors would assume responsibility for managing health care—from October 1, 2017, to January 1, 2018, to align with the mandated implementation date for TRICARE Select. DOD also delayed and lengthened a planned period for the department to make changes to beneficiary information in TRICARE's eligibility system. According to DOD and its contractors, this delay contributed to problems with enrollment processing backlogs that were not addressed until several months after health care delivery began. DOD experienced challenges during the T-2017 transition that resulted from weaknesses with its transition guidance and oversight. Specifically, DOD's guidance does not always specify the amount and types of data outgoing contractors have to share with incoming contractors. This led to contractor disagreements over data transfers, which DOD did not always resolve in a timely manner. Contractors reported that these issues contributed to problems after health care delivery began for the T-2017 contracts, such as with processing referrals. DHA also determined that some of DHA's oversight requirements, such as for specialty care referrals, were not feasible or effective, which limited some testing of contractors' readiness for health care delivery. This occurred in part because DOD's relevant subject matter experts did not review the requirements. DOD addressed most of the problems that occurred after health care delivery began by requiring the contractors to develop and implement corrective action plans. DOD and contractors are addressing some problems that have persisted, including problems with the contractors' provider directory accuracy in both regions and claims processing in one region. DOD has an opportunity to avoid similar problems in the future by improving the specificity of its transition guidance and effectiveness of its oversight requirements.


DOD generally accounts for about two-thirds of federal contracting activity. Some companies doing business with DOD may have an opaque ownership structure that conceals other entities or individuals who own, control, or financially benefit from the company. Opaque ownership could be used to facilitate fraud and other unlawful activity. The House Armed Services Committee report on the National Defense Authorization Act for fiscal year 2018 included a provision for GAO to examine the risks posed by contractors with opaque ownership and DOD's processes for identifying ownership. This report identifies types of fraud and other risks that opaque contractor ownership poses to DOD in the procurement process and assesses whether DOD has taken steps to address those risks. GAO reviewed applicable laws and regulations and interviewed DOD officials, including procurement staff and criminal investigators. GAO researched cases from 2012–2018 where contractors may have concealed or failed to disclose ownership information. GAO compared DOD's efforts to leading practices in GAO's Fraud Risk Framework. This is a public version of a sensitive report that GAO issued in September 2019. Information that DOD deemed sensitive involving ongoing investigations and certain internal controls and vulnerabilities has been omitted. The Department of Defense (DOD) faces several types of financial and nonfinancial fraud and national security risks posed by contractors with opaque ownership. These risks, identified through GAO's review of 32 adjudicated cases, include price inflation through multiple companies owned by the same entity to falsely create the appearance of competition, contractors receiving contracts they were not eligible to receive, and a foreign manufacturer receiving sensitive information or producing faulty equipment through a U.S.-based company. For example, one case involved an ineligible foreign manufacturer that illegally exported sensitive military data and provided defective and nonconforming parts that led to the grounding of at least 47 fighter aircraft, as illustrated below. DOD has taken some steps that could address some risks related to contractor ownership in the procurement process but has not yet assessed these risks across the department. DOD, in coordination with other agencies, revised the Federal Acquisition Regulation in 2014 to require contractors to self-report some ownership information. DOD has taken steps to identify and use ownership information—for example, as part of its supply-chain risk analysis when acquiring critical components. DOD has also begun a department-wide fraud risk management program, but it has neither assessed risks of contractor ownership across the department nor identified risks posed by contractor ownership as a specific area for assessment. Assessing risks arising from contractor ownership would allow DOD to take a strategic approach to identifying and managing these risks, make informed decisions on how to best use its resources, and evaluate its existing control activities to ensure they effectively respond to these risks.


DOD has become increasingly reliant on information technology (IT) and risks have increased as cybersecurity threats evolve. Cybersecurity experts estimate that 90 percent of cyberattacks could be defeated by implementing basic cyber hygiene and sharing best practices, according to DOD's Principal Cyber Advisor. Senate Report 115-262 includes a provision that GAO review DOD cyber hygiene. This report evaluates the extent to which 1) DOD has implemented key cyber hygiene initiatives and practices to protect DOD networks from key cyberattack techniques and 2) senior DOD leaders received information on the department's efforts to address these initiatives and cyber hygiene practices. GAO reviewed documentation of DOD actions taken to implement three cyber hygiene initiatives and reviewed recurring reports provided to senior DOD leaders. The Department of Defense (DOD) has not fully implemented three of its key initiatives and practices aimed at improving cyber hygiene. Carnegie-Mellon University defines cyber hygiene as a set of practices for managing the most common and pervasive cybersecurity risks. In discussions with GAO, DOD officials identified three department-wide cyber hygiene initiatives: the 2015 DOD Cybersecurity Culture and Compliance Initiative, the 2015 DOD Cyber Discipline Implementation Plan, and DOD's Cyber Awareness Challenge training. The Culture and Compliance Initiative set forth 11 overall tasks expected to be completed in fiscal year 2016. It includes cyber education and training, integration of cyber into operational exercises, and needed recommendations on changes to cyber capabilities and authorities. However, seven of these tasks have not been fully implemented. The Cyber Discipline plan has 17 tasks focused on removing preventable vulnerabilities from DOD's networks that could otherwise enable adversaries to compromise information and systems. Of these 17, the DOD Chief Information Officer is responsible for overseeing implementation of 10 tasks. While the Deputy Secretary set a goal of achieving 90 percent implementation of the 10 CIO tasks by the end of fiscal year 2018, four of the tasks have not been implemented. Further, the completion of the other seven tasks was unknown because no DOD entity has been designated to report on the progress. The Cyber Awareness training is intended to help the DOD workforce maintain awareness of known and emerging cyber threats, and reinforce best practices to keep information and systems secure. However, selected components in the department do not know the extent to which users of its systems have completed this required training. GAO's review of 16 selected components identified six without information on system users that had not completed the required training, and eight without information on users whose network access had been revoked for not completing training. Beyond the initiatives above, DOD has (1) developed lists of the techniques that adversaries use most frequently and pose significant risk to the department, and (2) identified practices to protect DOD networks and systems against these techniques. However, the department does not know the extent to which these practices have been implemented. The absence of this knowledge is due in part to no DOD component monitoring implementation, according to DOD officials. Overall, until DOD completes its cyber hygiene initiatives and ensures that cyber practices are implemented, the department will face an enhanced risk of successful attack. While two recurring reports have provided updates to senior DOD leaders on cyber information on the Cyber Discipline plan implementation, department leadership has not regularly received information on the other two initiatives and on the extent to which cyber hygiene practices are being implemented. Such information would better position leaders to be aware of the cyber risks facing DOD and make more effective decisions to manage such risks.


About 400 natural gas storage sites are important to the U.S. natural gas system, providing about 30 percent of the nation's energy. During a 2015 leak at a storage site near Los Angeles, about 8,000 families were temporarily relocated due to symptoms such as migraines, nausea, and respiratory problems. The leak raised concerns about health and safety risks from other storage sites. In 2017, GAO recommended that PHMSA take actions, including using baseline data to develop performance goals for its natural gas storage program. GAO was asked to review the health and environmental effects of activities at natural gas storage sites. This report, among other objectives, (1) assesses the extent to which PHMSA has developed its natural gas storage inspection program and (2) describes what is known about the potential health effects from chemicals in stored natural gas. GAO reviewed available documents about natural gas storage incidents from 2000 through 2018; compared PHMSA research, goals, and plans against leading planning practices; visited sites representing the three types of storage sites; and interviewed agency officials. In 2018, the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA) set a goal for its natural gas storage inspection program to inspect all approximately 400 natural gas storage sites within 5 years, according to agency officials. PHMSA expected that all 25 eligible states would help inspect sites, but only 10 states agreed to partner with the agency. As a result, the agency's inspection workload increased by almost 60 percent from when it set its goal, according to PHMSA data. Because of the increase in its inspection workload over its preliminary estimate, PHMSA does not have assurance that it has enough resources to meet its inspection goal. Furthermore, PHMSA has not used a workforce analysis to inform its budget requests. PHMSA officials said that the agency does not expect to have enough data until 2022 or 2023 to further inform analysis of its workforce. By analyzing factors affecting states' willingness to partner with PHMSA and its workforce needs on an ongoing basis, the agency would have better assurance that it has the staff it needs to meet its inspection goal. Health effects have been reported related to chemicals that may be found in stored natural gas. Several federal agencies—including the Environmental Protection Agency and the Agency for Toxic Substances and Disease Registry—have documented potential health effects of chemicals that may be found in stored natural gas. In addition, some chemicals may be added to natural gas, such as sulfur odorants that give natural gas a distinct smell in case of leaks. The combination of such chemicals varies from one natural gas storage site to another, based on the attributes of that site such as its geologic type and the extent to which sulfur odorants are added to the natural gas before storage. Many of these chemicals have been linked to adverse health effects. However, research is limited on the health effects of exposure to stored natural gas in general and on the effects in particular from exposure to chemicals that may occur in natural gas storage leaks or be present at the storage sites. Reports linking health effects are available on specific chemicals but not in the context of natural gas storage, based on GAO's literature review.


DOD has had longstanding organizational and management challenges that hinder collaboration. Section 911 of the NDAA for Fiscal Year 2017 directed the Secretary of Defense to, among other things, issue an organizational strategy that identifies critical objectives that span multiple functional boundaries, establish cross-functional teams to support this strategy, and provide related guidance and training. The NDAA for Fiscal Year 2017 also included a provision for GAO periodically to assess DOD's actions in response to section 911. GAO has issued a series of reports since June 2017 and made a number of recommendations to DOD. This report assesses the extent to which DOD has made progress in (1) implementing the requirements of section 911 and (2) establishing cross-functional teams. GAO reviewed documentation, interviewed cross-functional team members and other DOD officials, and compared DOD's actions to section 911 requirements and leading practices for cross-functional teams. Since GAO's August 2019 report, the Department of Defense (DOD) has taken actions to complete three additional statutory requirements of section 911 of the National Defense Authorization Act (NDAA) for Fiscal Year 2017, but has not completed three remaining requirements. These requirements are intended to support cross-functional teams and to promote department-wide collaboration (see table). Cross-functional teams rely on individuals with different types of expertise to work toward a common, well-defined goal, and are thought to deliver better and faster solutions to complex and fast-moving problems. DOD's approved organizational strategy addresses key requirements of section 911, including identifying critical objectives that would benefit from the use of cross-functional teams and providing for the appropriate use of these teams. However, the strategy did not include practical, specific implementation steps to guide DOD's efforts to advance a collaborative culture, which had been included in earlier draft versions of the strategy. These steps had aligned with GAO's leading practices for mergers and organizational transformations. Specific implementation steps like those included in earlier drafts of the organizational strategy offered DOD a clear path forward for pursuing the goals of section 911 and for promoting a collaborative culture. Absent identifying and documenting specific implementation steps, it is less clear how DOD intends to implement the organizational strategy and assess progress toward its goals. DOD's existing cross-functional team charged with improving electromagnetic spectrum operations and defending its communication systems from attacks is continuing its work by issuing a statutorily mandated report, among other efforts, but DOD has not clarified responsibility for funding the team. GAO will continue to monitor DOD's progress toward providing such support to the team as GAO recommended in August 2019. In addition, DOD has designated the Close Combat Lethality Task Force and the Protecting Critical Technology Task Force as new cross-functional teams, although they meet only some of the section 911 requirements. DOD officials said they will ensure that the newly designated teams meet these requirements, including providing required training.


DOD invests in a number of incentives to recruit and retain its nearly 15,000 military physicians and dentists, such as providing a tuition-free education to medical and dental students who in return agree to serve as military physicians or dentists for a specific amount of time. Section 597 of the John S. McCain National Defense Authorization Act for Fiscal Year 2019 included a provision for GAO to review military physicians' and dentists' compensation, among other things. This report addresses, among other objectives, (1) how compensation for military physicians and dentists compared to private sector civilians with comparable skills in 2017, and (2) the extent to which DOD has developed an approach to recruit and retain military physicians and dentists through a package of incentives that reflect key principles of effective human capital management. GAO compared military and civilian cash compensation for 2017—the most recent year of data amongst data sources, assessed incentive packages against key principles of human capital management, and conducted surveys and held focus groups to obtain the perspectives of current military medical students and residents regarding military service obligations. In 2017, cash compensation for military physicians and dentists in most of the 27 medical and dental specialties GAO reviewed was generally less than the median compensation of private sector civilians, but the Department of Defense (DOD) provides substantial deferred and noncash benefits, such as retirement pensions and tuition-free education, whose value to servicemembers is difficult to determine. GAO found that for 21 of the 27 physician and dental specialties, the maximum cash compensation was less than the private sector civilian median within four officer pay grades (O-3 to O-6) (see figure for number of physician specialties by pay grade). Moreover, cash compensation for military physicians and dentists was less than the private sector civilian median at key retention points, such as after physicians and dentists fulfill their initial active-duty service obligations. DOD recruits and retains physicians and dentists through a package of incentives, including tuition-free medical or dental school and special and incentive pays, such as multi-year retention bonuses. However, DOD does not consistently collect information related to the following three key principles of effective human capital management to help inform investment decisions in its package of recruitment and retention incentives: Replacement costs . DOD does not consistently collect information on replacement costs of military physicians and dentists. However, DOD has previously identified replacement costs as a factor in assessing the appropriateness of incentive pays. Current and historical retention information . DOD does not consistently collect information on retention of physicians and dentists, specifically acceptance rates for retention bonuses, to help assess the effectiveness of these bonuses. Private sector civilian wages. DOD does not consistently collect information on private sector civilian wages. Officials stated that civilian wages are not a driving factor when considering adjustments to special and incentive pays, in part because DOD cannot always match civilian sector compensation for military physicians and dentists. By collecting and using this information to help inform its decision-making, DOD would be better positioned to assess the effectiveness of its incentives to recruit and retain military physicians and dentists and make sound investment decisions for the future.


DOD invests tens of billions of dollars each year in major defense acquisition programs, designing and developing technologically advanced weapon systems that warfighters expect will meet specific performance requirements, including reliability requirements. Systems that are not reliable make it more difficult for warfighters to perform their missions. GAO was asked to examine DOD weapon system reliability. This report addresses (1) how selected companies in the commercial sector address reliability, (2) how selected DOD acquisition programs addressed reliability, and (3) the extent to which DOD leadership has highlighted key reliability practices. GAO collected information on leading commercial practices at the 2019 Reliability and Maintainability Symposium and from four commercial companies known for delivering reliable products. GAO also assessed how seven DOD acquisition programs—both older and newer, and representing all the military services—addressed reliability; reviewed key documents and interviewed knowledgeable officials; and reviewed reliability-related guidance and policy from senior DOD leaders. The commercial companies GAO reviewed proactively address reliability. They strive to identify reliability issues at the component level early in the development process to avoid expensive rework after producing an entire system. GAO found these companies focus on the following key practices: 1. Leveraging reliability engineers early and often 2. Establishing realistic reliability requirements 3. Emphasizing reliability with their suppliers 4. Employing reliability engineering activities to improve a system's design throughout development GAO found that the seven Department of Defense (DOD) acquisition programs it reviewed did not consistently adhere to these key practices (see figure). These programs often prioritized schedule and cost over incorporating the key reliability practices, and these systems generally were not as reliable as promised. In 2019, DOD highlighted in a policy memorandum the importance of emphasizing reliability with contractors. However, the other three key practices have not been similarly highlighted. DOD has taken steps to accelerate weapon system development, and decision-making authority has been delegated to the military services. In an environment emphasizing speed, without senior leadership focus on a broader range of key reliability practices, DOD runs the risk of delivering less reliable systems than promised to the warfighter and spending more than anticipated on rework and maintenance of major weapon systems.


DOD is in the pre-trial phase of the military commissions' proceedings it is conducting to try the alleged perpetrators of terrorist attacks on the USS Cole and September 11, 2001. The Military Commissions Act of 2009 specifies that proceedings shall be publicly held unless the judge makes findings that justify a closed session, such as national security concerns. The National Defense Authorization Act for Fiscal Year 2018 included a provision for GAO to study the feasibility and advisability of expanding access to commissions' proceedings that are open to the public. This report describes (1) how DOD currently facilitates public access to proceedings; (2) challenges the public faces in gaining access to or obtaining information on proceedings; and (3) what is known about potential options to address public access challenges, including any related tradeoffs. GAO analyzed relevant laws and guidance; conducted a non-generalizable survey that received responses from 248 victims of terrorist attacks and their family members; collected data from DOD's website to analyze timeliness of court document postings; and interviewed relevant DOD officials and other government and non-government stakeholders. The Department of Defense (DOD) currently facilitates public access to and information about military commissions' proceedings at Naval Station Guantanamo Bay (NSGB) in Cuba by: communicating directly with victims and their family members about hearings; enabling selected members of the public to view proceedings in-person; providing five sites in the United States to view proceedings remotely via closed circuit television (CCTV); and making information such as court documents available on the Office of Military Commissions' website. The public faces various challenges in gaining access to military commissions' proceedings or obtaining information about them. First, some aspects of the proceedings limit public access, but addressing them is largely outside of DOD's control. For example, proceedings, by law, are held on NSGB—a location that is largely inaccessible to the general public. Further, cases currently before the military commissions have spent 4-10 years in pre-trial hearings with trials yet to be scheduled, which some suggest has lessened media coverage and public visibility. Second, there are other challenges that DOD officials have acknowledged that they have a greater ability to address. For example, the courtroom gallery is limited to 52 seats for those permitted to travel to NSGB. Additionally, all five CCTV sites are located within a span of 600 miles on the East Coast of the United States. However, victims and their family members—the primary intended users of these sites—often live a significant distance from these locations. A number of options may potentially address some of the public access challenges identified. DOD could potentially expand the viewing gallery to accommodate more people as part of an ongoing project to renovate the NSGB courtroom. However, DOD officials cautioned that it would require a commensurate increase in the lodging needed to house more visitors, which may not be supported by current levels of resources. Further, DOD has two potential options for addressing challenges with the remote viewing of proceedings. First, DOD could potentially increase the number and geographic dispersion of CCTV sites. Second, DOD could potentially maximize public access by broadcasting proceedings via the television or internet. DOD officials acknowledged that both options are possible and likely would require a relatively small outlay of resources. However, broadcasting proceedings via the television or internet is currently prohibited by DOD's regulation, and DOD officials were especially concerned with the security implications of this option. DOD has not assessed the tradeoffs nor identified or analyzed the risks of options for expanding public access to military commissions' proceedings. Consequently, DOD has not developed a strategy to address challenges or identified the resources needed to achieve its public access goals. Until DOD does so, it cannot be sure that it is meeting its goal of maximizing public access and may not be prepared for the potential increased demand for public access that is anticipated when proceedings move into the trial phase.


DOD is the largest contracting agency in the federal government, obligating about $320 billion for contracts in fiscal year 2017. Some DOD contracts—including some in the manufacturing and construction industries—involve work that can be dangerous, and questions have been raised about working conditions for these workers. The National Defense Authorization Act for Fiscal Year 2018 includes a provision for GAO to review issues related to the safety and health records of DOD contractors. This report examines: (1) the incidence of prior serious safety or health violations among selected companies with DOD manufacturing and construction contracts, and (2) how DOD and selected DOD components address contractor workplace safety and health during the acquisition process. GAO matched federal contracting data for fiscal year 2017 to OSHA inspection data for fiscal years 2013-2017 (most recent available); interviewed officials from OSHA, DOD, selected military departments, and selected DOD components; reviewed documentation from six selected DOD contract files; and reviewed relevant federal laws and regulations, policy, and guidance. Some selected companies with Department of Defense (DOD) manufacturing or construction contracts in fiscal year 2017 were previously cited for serious safety or health violations, according to GAO's analysis of federal data. Of the 192 companies with DOD contracts GAO selected for review, 106 had been inspected by the Department of Labor's (DOL) Occupational Safety and Health Administration (OSHA) or state occupational safety and health agencies during fiscal years 2013 through 2017. These inspections resulted in 83 companies being cited for at least one violation, including 52 with at least one serious violation (see figure). However, available data do not allow a determination of whether these violations occurred during work on a DOD contract because OSHA inspection data do not include that information. The incidence of violations among all inspected companies with DOD contracts cannot be determined because OSHA does not require its staff to obtain and enter a corporate identification number in its inspection data, which is needed to match contracting data to inspection data. As a result, OSHA's data do not consistently include these numbers, and users of OSHA's website cannot use these numbers to search for companies' previous violations. According to federal internal control standards, management should share the quality information necessary to achieve the entity's objectives. Unless OSHA explores the feasibility of requiring a corporate identification number in its inspection data, website users will likely have difficulty obtaining accurate information on individual companies' previous violations. DOD contracting officials have opportunities during the acquisition process to address contractor workplace safety and health. For example, before awarding certain types of contracts, officials may consider workplace safety and health information when they evaluate prospective contractors' performance on past contracts. However, the past performance information that is available for officials to consider varies by DOD component. One component has a practice of requiring construction contractors to be rated on workplace safety at the completion of the contract, but DOD does not require a safety performance rating department-wide. As a result, contracting officials in other components may lack readily accessible information on contractors' past safety performance, and DOD may miss opportunities to consider safety concerns when awarding new contracts, particularly those in high-risk industries with relatively high rates of occupational injuries, such as manufacturing and construction.


DOD manages a global real-estate portfolio with an almost $1.2 trillion estimated replacement value. Since 2010, DOD has identified climate change as a threat to its operations and installations. In January 2019, DOD stated that the effects of a changing climate are a national security issue with potential impacts to the department's missions, operational plans, and installations. GAO was asked to assess DOD's progress in developing a means to account for potentially damaging weather in its facilities project designs. GAO examined the extent to which DOD has taken steps to incorporate resilience to extreme weather and climate change effects into (1) selected installation master plans and related planning documents, and (2) selected individual installation facilities projects. GAO reviewed DOD documents related to increasing climate resilience, conducting installation master planning, and designing facilities projects. GAO visited or contacted a non-generalizable sample of 23 installations that had been associated with one or more climate vulnerabilities. Department of Defense (DOD) installations have not consistently assessed risks from extreme weather and climate change effects or consistently used projections to anticipate future climate conditions. For example, DOD's 2018 preliminary assessment of extreme weather and climate effects at installations was based on the installations' reported past experiences with extreme weather rather than an analysis of future vulnerabilities based on climate projections. Fifteen of the 23 installations GAO visited or contacted had considered some extreme weather and climate change effects in their plans as required by DOD guidance, but 8 had not. For example, Fort Irwin, California, worked with the U.S. Army Corps of Engineers to improve stormwater drainage after intense flash flooding caused significant damage to base infrastructure. By contrast, Joint Base Pearl Harbor-Hickam, Hawaii, did not include such considerations in its plans, although it is located in an area subject to tropical storms and where further sea level rise is anticipated. GAO also found that most of the installations had not used climate projections, because they lack guidance on how to incorporate projections into their master plans. Not assessing risks or using climate projections in installation planning may expose DOD facilities to greater-than-anticipated damage or degradation as a result of extreme weather or climate-related effects. Eleven of the 23 installations we reviewed had designed one or more individual facilities projects to increase the resilience of the facilities to extreme weather and climate change effects. However, project designs generally did not consider climate projections, according to installation officials. These officials told us that DOD lacks guidance on how to use climate projections that involve multiple future scenarios and different time periods. Until DOD updates its facilities design standards to require installations to consider climate projections in project designs, identify authoritative sources for them to use, and provide guidance on how to use projections, installation project designers may continue to exclude consideration of climate projections from facilities project designs, potentially making investments that are planned without consideration of climate-related risks.


DOD officials estimate spending an average of $4 billion each year to acquire and sustain wideband satellite communications that provide fast and reliable voice, video, and data transmissions critical to military operations. DOD is considering how to meet its future wideband needs across many different operating environments and scenarios. The National Defense Authorization Act for Fiscal Year 2016 required DOD to conduct a Wideband Communications Services AOA to identify ways to replace current systems as the satellites reach the end of their service lives. The National Defense Authorization Act for Fiscal Year 2017 contained a provision for GAO to assess DOD's analysis. This report addresses (1) whether the Wideband AOA was comprehensive, (2) how DOD solicited input from stakeholders, and (3) the conclusions DOD reached through the Wideband AOA. GAO reviewed the Wideband AOA along with DOD policies, documentation, and analyses; interviewed DOD officials and commercial stakeholders; and assessed the AOA against best practices for a comprehensive AOA process. The Department of Defense (DOD) conducted a comprehensive analysis of alternatives (AOA) process for wideband satellite communications, as determined through an assessment of the AOA against relevant GAO best practices. A comprehensive analysis of alternatives process indicates that the analysis team thoroughly addressed a wide range of possible satellite system alternatives. DOD used multiple methods to obtain stakeholder input, in accordance with its Wideband AOA study plan. For example, the study team incorporated input from across the military services and operational users, among others. Moreover, the Air Force and Defense Information Systems Agency conducted interrelated studies to provide additional information to the Wideband study team. DOD's analysis concluded that integrating military and commercial systems into a hybrid architecture would be more cost effective and capable than either acquisition approach alone. However, DOD also found that it needs more information to select its next satellite communications architecture and made recommendations for further study. Examples of these recommendations include: Develop an enterprise satellite communications terminal strategy – DOD found the magnitude of replacing user terminals to work with new systems was challenging and that more information on emerging technology and possible changes to terminal acquisition approaches would help DOD address this challenge. Invest in commercial technologies – DOD found that it lacked detailed technical information on commercial systems' cyber protections and that additional information on such protections would help DOD determine the extent to which they would meet DOD's needs. Such recommendations align with GAO's acquisition best practices for knowledge-based decision-making and have the potential to improve the department's satellite communications acquisitions. However, DOD stakeholders said there is no formal plan to guide and coordinate implementation of the AOA recommendations. Without such a plan, DOD is at increased risk of not having the information it needs to make timely, knowledge-based decisions on future systems to provide critical communications for military operations.


DOD operates about 240 commissaries and 2,500 exchanges that sell groceries and retail goods and services to servicemembers, their families, and retirees. Commissaries and exchanges are operated by four resale organizations, and in November 2018 a DOD task force completed a business case analysis on consolidating those organizations. The National Defense Authorization Act for Fiscal Year 2020 included a provision for GAO to review DOD's business case analysis. This report evaluates the extent to which (1) DOD's business case analysis for consolidating the four resale organizations provided reliable savings and cost estimates and (2) the military departments concurred with the business case analysis and DOD shared their accompanying comments with Congress. GAO evaluated the business case analysis against DOD- and GAO-identified key elements of economic analyses; reviewed comments on the business case analysis; and interviewed DOD officials. A Department of Defense (DOD) task force's business case analysis for consolidating the defense resale organizations—the Defense Commissary Agency (DeCA), the Army and Air Force Exchange Service, the Navy Exchange Service Command, and Marine Corps Community Services—may not provide reliable savings and cost estimates. These organizations sell groceries and retail goods to servicemembers, their families, and retirees. The task force recommended consolidating the four resale organizations into a single organization, estimating “net savings” (i.e., savings minus costs) of about $690 million to $1.3 billion during the first 5 years. However, the task force may have overestimated savings and underestimated costs. Savings from reducing the cost of goods sold. The task force estimated that DOD would save several hundred million dollars annually by reducing the cost of purchasing goods that are resold in stores. Specifically, the task force multiplied the fiscal year 2017 total cost of goods sold for all four resale organizations by industry benchmarks, reasoning that mergers lead to more savings when merging organizations sell a high amount of identical products. However, task force data show that DeCA and the exchange organizations have limited identical products; the overlap between DeCA products and those of at least one exchange organization amounts to less than one-third of the total cost of goods sold. Thus, multiplying the benchmarks by the total cost of goods sold for all four organizations may not have been appropriate. Information technology (IT) costs. The task force estimated the costs of developing new, common IT systems to operate a consolidated resale organization to be between $326 million and $401 million, about 50 percent of estimated consolidation costs. The task force stated that it based IT cost estimates on data resale organizations provided for major upgrades or system replacements. But GAO found that about 40 percent of the IT cost estimate was based on minor upgrades or partial replacements, not major upgrades or system replacements. Thus, the estimate may be understated. Headquarters relocation costs. According to the task force, there will be costs if DOD decides to relocate the four defense resale organizations to a new headquarters location. However, the task force did not include cost estimates for relocation in its business case analysis. According to federal law, the operation of the commissary and exchange systems may not be consolidated unless authorized by Congress. Until the task force reassesses and updates, as necessary, its savings and costs estimates, DOD and Congress will not have reliable information to consider resale consolidation. The military departments officially concurred with the business case analysis, but provided written comments detailing fundamental concerns with the analysis, such as the use of proprietary industry benchmarks and the estimated savings and costs. In April 2019, DOD reported to Congress that the military departments agreed with consolidation, but did not disclose the accompanying comments. Without more complete reporting of those comments, Congress has limited visibility of the views of the organizations involved in a potential consolidation.


DOD operates depots nationwide to maintain complex weapon systems and equipment through overhauls, upgrades, and rebuilding. These depots are crucial to sustaining military readiness by ensuring that the military services can regularly maintain critical weapon systems and return them to the warfighter for use in training and operations. For fiscal year 2018, DOD reported $19 billion in total maintenance expenditures and about 84,000 personnel performing depot-level maintenance. In June 2018, the Senate Armed Services Committee, in a report accompanying a bill for the National Defense Authorization Act for Fiscal Year 2019, included a provision for GAO to review DOD's sharing and implementation of best practices and lessons learned among the depots. GAO evaluated the extent to which DOD experiences benefits and has challenges with (1) sharing and (2) implementing best practices and lessons learned among the depots. GAO reviewed agency guidance; surveyed 17 depots; conducted site visits at five depots; and interviewed DOD, military service, and depot officials. The Department of Defense (DOD) experiences benefits from sharing best practices and lessons learned among its depots, but communication and organization challenges exist. Best practices and lessons learned are shared among the depots through a variety of venues, including networking, working groups, and benchmarking trips to other depots. However, DOD has communication challenges, such as the lack of awareness of venues for sharing information. While Office of the Secretary of Defense officials reported posting a list of working groups, the list only contains three of the more than 60 working groups GAO identified. Without a centralized list of sharing venues and points of contact, it is unclear what groups exist and who to contact to participate, which may impede sharing of best practices and lessons learned. Further, while the Army stated it established lessons learned organizations for sharing maintenance best practices and lessons learned, it did not maintain them due to organizational restructuring and resource constraints. Establishing and maintaining effective organizations dedicated to sharing materiel best practices and lessons learned would encourage knowledge sharing among the Army depots. DOD is experiencing benefits and taking steps to mitigate challenges with implementing best practices and lessons learned among the depots. Depots reported that implementing some best practices and lessons learned has led to benefits, including time and cost savings. For example, Navy Fleet Readiness Center Southwest, California, implemented an intermittent fault detection system from Ogden Air Logistics Complex, Utah, on its F/A-18 aircraft generators. According to officials, the depot reduced repair time from 90 days to 30 days and quadrupled the generators' time between failures. Depots reported a variety of challenges to implementing lessons learned and best practices, including a lack of resources, lengthy approval processes, and acquisition and technology restrictions. DOD is taking steps to mitigate challenges to implementation, such as creating a new technology tool for viewing metrics on weapon systems' cost and availability which will allow senior leaders to steer resources to needed programs.


DOD plans to spend about $65 billion from fiscal year 2019 to 2023 on space acquisition programs—including satellites, launch vehicles, ground components, and user equipment. DOD's space acquisition personnel perform a variety of activities, such as preparing and reviewing acquisition documents, to manage or oversee programs that develop or procure space capabilities. DOD recently announced it plans to establish a new Space Development Agency and a United States Space Command. A House Report accompanying a bill for the 2017 National Defense Authorization Act contained a provision for GAO to review DOD's space acquisition workforce. This report examines, among other things, what is known about the size, mix, and location of that workforce. GAO collected data from DOD's acquisition workforce data systems and multiple space acquisition organizations. GAO interviewed officials from these organizations and from a non-generalizable sample of 10 space acquisition programs, representing a range of dollar values and stages in the acquisition process. The Department of Defense (DOD) does not routinely monitor the size, mix, and location of its space acquisition workforce. However, data GAO collected and aggregated from multiple DOD space acquisition organizations show that at least 8,000 personnel in multiple locations nationwide were working on space acquisition activities at the end of 2017 (see figure). Also as shown, military and civilian personnel comprise the majority of the overall workforce, while contractor and Federally Funded Research and Development Center personnel also provide support. Several factors hinder DOD's ability to collect data needed for a comprehensive view of its space acquisition workforce: DOD does not maintain a complete list of its space acquisition programs; DOD's workforce data systems are not configured to identify personnel working on space acquisition activities; and DOD space acquisition personnel are dispersed across organizations and some personnel support both space and non-space programs. Without complete and accurate data, DOD cannot assess gaps in the overall capabilities of the space acquisition workforce. Identifying space programs and collecting such data would also better position DOD to ensure that the appropriate space acquisition personnel are assigned to the new Space Development Agency and the United States Space Command. Finally, comprehensive data on the space acquisition workforce would also be beneficial to support DOD's efforts related to its recent legislative proposal regarding the establishment of the United States Space Force.


About 46 million of the 56 million acres of the land that the federal government holds in trust for the benefit of Indian tribes and their members has an agricultural purpose. However, tribal agriculture and economic development experts have noted that Indian tribes and their members may need improved access to agricultural credit. Congress included a provision in statute for GAO to review the ability of FCS to meet the agricultural credit needs of Indian tribes and their members on tribal lands. This report describes (1) what is known about the agricultural credit needs of Indian tribes and their members, (2) barriers stakeholders identified to agricultural credit on tribal lands, (3) FCS authority and actions to meet those agricultural credit needs, and (4) stakeholder suggestions for improving Indians' access to agricultural credit on tribal lands. GAO explored potential data sources on Indians' agricultural credit needs, conducted a literature review, and reviewed statutes and regulations governing tribal lands and FCS. GAO also reviewed the marketing plans and written responses of a nongeneralizable sample of 11 FCS associations whose territories included tribal lands with high levels of agricultural activity. GAO interviewed stakeholders from a sample of seven tribes (generally selected based on tribal region and agricultural activity), experts in tribal agriculture and economic development (selected based on relevant publications, Congressional testimonies, and others' recommendations), and representatives from FCS and its regulator, the Farm Credit Administration, and other relevant government agencies. Limited data are available on the needs of Indian tribes and their members for agricultural credit, such as operating or equipment loans, to develop and expand agricultural businesses on tribal lands. Federal regulations have generally prohibited lenders from inquiring about the personal characteristics, such as race, of applicants on nonresidential loans. Some tribal stakeholders and experts said that tribal members may not have applied for agricultural credit because they heard of other tribal members being denied loans. They said that tribal members likely obtain agricultural credit from Department of Agriculture programs or tribal lenders. Another potential source of agricultural credit is the Farm Credit System (FCS), a government-sponsored enterprise that includes 69 associations that lend to farmers and ranchers. Tribal stakeholders and experts reported a general lack of commercial credit on tribal lands due to the following factors: Land use restrictions. Most tribal lands only can be used as loan collateral in certain circumstances or with federal permission. Administrative process delays. Tribal members reported often encountering delays obtaining necessary federal loan documents. Legal challenges. Lenders reported concerns about their ability to recover loan collateral due to the unique legal status of tribes. Loan readiness. Tribal members may have no or poor credit histories and be unfamiliar with the paperwork required for an agricultural loan, such as a business plan. FCS is authorized to provide a range of credit services to eligible agricultural producers, which may include Indian tribes, tribal businesses, and tribal members. FCS associations must obtain land as collateral for long-term real estate loans, but are not required to do so for shorter-term loans, such as for operating costs or equipment purchases. Some FCS associations GAO contacted reported making loans to Indian tribes or their members. In a sample of 11 FCS associations with tribal lands in their territory, eight said they have loaned to tribes or their members in the past 2 years. GAO's review of these 11 associations' marketing plans and written responses to GAO follow-up questions found that seven noted outreach—such as support for agricultural education activities—targeted to tribes and their members. The other four reported broad and general outreach efforts that also included minority groups. To improve access to agricultural credit on tribal lands, stakeholders discussed several options. For example, some stakeholders discussed the potential for partnerships between commercial or government lenders and tribal lenders (such as Native Community Development Financial Institutions) and increased use of loan guarantees. Some stakeholders also discussed actions tribes could take to ease barriers to lending, such as adopting their own leasing procedures to reduce administrative processing time with federal agencies for certain loans.


DOD provided health care to more than 9 million eligible beneficiaries through TRICARE in fiscal year 2018. Most of these beneficiaries were enrolled in TRICARE's managed care plan—TRICARE Prime. However, about 2 million beneficiaries received care primarily from civilian providers through TRICARE's non-Prime options: TRICARE Standard and Extra. Effective January 1, 2018, these two options were eliminated and TRICARE Select was implemented. TRICARE Select has similar benefits for provider choice and obtaining care from civilian providers as TRICARE Standard and Extra, but includes access standards to ensure at least 85 percent of enrollees are covered by TRICARE's network of civilian providers, among other things. The National Defense Authorization Act (NDAA) for Fiscal Year 2008 included a provision for GAO to review results of DOD surveys of non-Prime beneficiaries and civilian providers. Additionally, the NDAA for Fiscal Year 2017 included a provision for GAO to review access to care after implementation of TRICARE Select in 2018. This report addresses both provisions. GAO analyzed DOD's survey results to determine changes after implementation of TRICARE Select in (1) non-Prime beneficiaries' ratings of TRICARE, (2) non-Prime beneficiaries' reported ability to find providers and obtain appointments, and (3) civilian providers' reported acceptance of TRICARE. GAO analyzed the results of the 2017-2019 surveys, and interviewed agency officials and DOD contractors. DOD provided technical comments, which GAO incorporated as appropriate. On January 1, 2018, the Department of Defense (DOD) implemented a new health plan option—TRICARE Select—for beneficiaries who primarily obtain care from civilian providers rather than through TRICARE's managed care plan—TRICARE Prime. DOD surveys indicate few changes in these non-Prime beneficiaries' satisfaction and access to care during the first year following the implementation of TRICARE Select, though GAO cannot directly attribute these differences to implementation due, in part, to other changes in the TRICARE program during the same time frame. Specifically, GAO found the following: There was no change in the percent of beneficiaries reporting positive ratings of their TRICARE health care and health plans—80 percent and 68 percent, respectively—in the first year of TRICARE Select. There was an increase in the percent of beneficiaries reporting problems accessing specialty providers from 18 to 24 percent in the first year of TRICARE Select. However, as the figure shows, there was no statistically significant change in the percent of beneficiaries reporting they received care as soon as needed for primary and specialty care appointments. There was no change in the percent of providers that reported accepting new TRICARE patients if they were also accepting any new patients—about 90 percent of primary care and specialty care providers, and 47 percent of mental health care providers—in the first year of TRICARE Select.


DOD relies on PME and JPME to prepare its military personnel throughout their careers for the intellectual demands of complex contingences and major conflicts that typically involve more than a single military service. However, according to DOD's summary of the 2018 National Defense Strategy, PME “has stagnated, focused more on the accomplishment of mandatory credit at the expense of lethality and ingenuity.” The Conference Report accompanying the John S. McCain National Defense Authorization Act for Fiscal Year 2019 included a provision for GAO to evaluate DOD PME and JPME institutions. This report examines the extent to which (1) the military services' PME programs have met civilian and JPME accreditation requirements, (2) OSD has assessed the effectiveness of the military services' PME programs, and (3) USD (Comptroller) has monitored the military services' PME program budget data. GAO analyzed applicable laws and policy, analyzed accreditation and budget information, and interviewed officials from the military services' intermediate- and senior-level resident PME programs. All of the military services' intermediate- and senior-level officer Professional Military Education (PME) programs have met civilian and met or partially met Joint PME (JPME) accreditation requirements. However, not all of the military services' PME programs met the JPME seminar student mix requirement of at least one student from the nonhost military department. For example, the Army's intermediate-level PME program did not meet its Sea Service (i.e., Navy, Marine Corps, and, in certain instances, Coast Guard) requirement (see table). GAO's analysis found that the Navy could have assigned officers to Air Force and Army programs while not harming participation in its own seminars. Without taking steps to improve Sea Service participation, students lose opportunities to interact with students from other military departments, which officials have identified as critical to joint acculturation. The Office of the Secretary of Defense (OSD) has taken steps to improve its oversight of the military services' PME programs, but is limited in its ability to assess their effectiveness. Department of Defense (DOD) guidance states that performance measurement is a means of evaluating efficiency, effectiveness, and results and that a balanced performance measurement scorecard includes nonfinancial and financial measures focusing on quality, cycle time, and costs. While OSD is in the process of developing some performance measures, it is not planning to require the military services to track program costs. Implementing its planned measures and establishing costs as a performance measure will better position OSD to assess the effectiveness of PME programs. The Under Secretary of Defense (USD) (Comptroller's) ability to monitor the military services' PME programs is limited by incomplete and inconsistent reporting of service budget request data. DOD guidance does not require the Marine Corps to submit an annual budget request data exhibit for its senior-level PME program and existing guidance for programs that are reported does not specify how to uniformly account for costs. Without complete and uniform budget request data, USD(Comptroller) is challenged in monitoring these programs.


DOD remains the only major federal agency that has been unable to obtain a financial statement audit opinion. One of the contributing factors is DOD's large volume of nonroutine accounting adjustments, which are used for recording corrections or adjustments in an accounting system. This report examines accounting adjustments and their effect on the reliability of DOD's financial information, the extent to which DOD has established and implemented policies and procedures for recording accounting adjustments, and the extent to which DOD has taken actions to reduce adjustments recorded at the consolidated level. For this report, GAO reviewed DOD and DFAS's policies and procedures, interviewed DOD officials about the adjustment process, and reviewed initiatives to reduce the number of adjustments being recorded. GAO also selected a random sample of 242 adjustments recorded at the DOD consolidated level for the fourth quarter of fiscal year 2018 to determine whether the adjustments were recorded in accordance with established policies. While the use of accounting adjustments is a common practice, the Department of Defense's (DOD) reliance on a large volume of nonroutine adjustments to prepare its financial statements is primarily a result of deficient business processes and limitations in accounting systems that DOD components use to process financial information. For example, the Defense Finance and Accounting Service (DFAS) continues to rely on forced-balance adjustments to replace the financial information that DOD's components submit to force agreement with Department of the Treasury balances without reconciling and researching the cause of differences (see figure). The recording of these adjustments was identified as a material weakness in DOD's internal control over financial reporting in its fiscal year 2018 financial statement audit. GAO found that DOD and DFAS policies and procedures for accounting adjustments are insufficient, outdated, and inconsistently implemented. For example, DOD's current policies do not define what constitutes adequate supporting documentation for system-generated adjustments, nor have DOD and DFAS established policies for identifying the cause of the adjustments, developing and implementing action plans to reduce the need for adjustments, and monitoring the effectiveness of those action plans. Because DOD and DFAS are not ensuring that their policies and procedures are up-to-date and consistently implemented, there is an increased risk that inaccurate, invalid, or unapproved adjustments will be recorded in DOD's core financial reporting system, resulting in a misstatement in DOD's consolidated financial statements. DOD and DFAS have undertaken initiatives to address some of the issues that contribute to the need for adjustments. Both organizations have developed strategies to decrease adjustments; however, neither has developed specific outcomes or detailed procedures for achieving stated goals in the strategies. Without clear procedures on how to implement its initiatives and a complete understanding across DOD of the issues contributing to the need for accounting adjustments, there is an increased risk that management efforts to reduce adjustments at the DOD consolidated level will be inefficient and ineffective.


DOD reported in January 2019 that critical installations are at risk of water scarcity—that is, of not having sufficient water available to meet their mission needs. According to military department officials, installations depend on water for activities such as training, weapons testing, fire suppression, and sanitation. In its 2018 Fourth National Climate Assessment , the U.S. Global Change Research Program reported that warming temperatures will continue to cause worsening droughts and the decline of surface water quality. Senate Report 115-262 included a provision for GAO to review DOD's identified or potential effects of water scarcity. For this report, GAO evaluated the extent to which DOD has assurance that it is using reliable information to identify installations at risk of water scarcity. GAO analyzed DOD's six assessments conducted from April 2017 through January 2019 to identify installations at risk of water scarcity and compared the assessments with five leading practices for identifying and analyzing water scarcity. GAO also interviewed officials from OSD and the military departments and contacted a nongeneralizable sample of 17 installations identified in OSD's assessments to reflect diversity in military service, mission, and water scarcity. GAO found that the Department of Defense (DOD) does not have assurance that it is using reliable information regarding which installations are at risk for water scarcity. When comparing the results of six Office of the Secretary of Defense (OSD) and military department assessments on installations vulnerable to water scarcity, GAO found that they varied markedly, raising questions about their quality and about which source of information DOD is using to determine which installations are vulnerable to water scarcity (see figure). An OSD official stated that the three OSD-produced assessments provided the best information available on which installations are at risk of water scarcity. However, GAO found that these assessments did not reflect four of five leading practices for identifying and analyzing water scarcity—practices that contribute to a reliable assessment of water availability. Specifically, OSD did not always (1) identify current water availability, (2) identify future water availability, (3) take into account all sources of water, or (4) precisely identify locations. Further, although GAO found that the three military department assessments aligned with all leading practices, OSD officials disagreed as to whether these assessments can and should be used to identify installations at risk of water scarcity across the defense enterprise. Until OSD resolves the question as to whether it should conduct a department-wide assessment of installations that aligns with leading practices or whether it should rely on the military department assessments, the department will not have assurance that it is using reliable information to assess water scarcity.


DOD space systems provide critical capabilities that support military and other government operations. They can also be expensive to acquire and field, costing billions of dollars each year. As DOD seeks to replenish its satellite constellations, it faces a number of challenges to ensuring funds are used effectively. Because space-based capabilities are fundamental to U.S. national security and civilian activities, it is essential that DOD manage its space system acquisitions carefully and avoid repeating past problems. This statement provides an update on DOD's space acquisitions, focusing on challenges facing acquisitions of new space systems. This statement is based on GAO reports issued over the past 10 years on DOD space programs. In addition it draws on recent work performed in support of GAO's 2019 annual reports on the progress of major defense acquisition programs as well as duplication, overlap, and fragmentation across the federal government, among other sources. DOD is simultaneously undertaking new major acquisitions to replenish its missile warning, protected communications, navigation, and weather satellites. At the same time, it is boosting efforts to increase space situational awareness and protect space assets. Such widespread acquisition acitivites could face a wide range of resource and management challenges that GAO has reported on, including: Growing threats to satellites . Threats to satellites from both adversaries— such as jamming and cyber attacks—and space debris are increasing. DOD is making changes to how it designs its space systems to increase the resilience and survivability of space capabilities. But it has been challenged in adopting new approaches, such as using commercial satellites to host payloads, and in prioritizing cybersecurity for all of its weapon systems. For hosted payloads, GAO recommended, and DOD concurred, that the department bolster and centralize collection and analysis of cost, technical, and lessons learned data. Implementing leadership changes . DOD is planning major changes to leadership for space. It recently proposed legislation to establish a United States Space Force—initially to be housed within the Department of the Air Force—that would, according to the President's Space Policy Directive, consolidate existing military space activities and minimize duplicative efforts across DOD. GAO found in July 2016 that changes are needed to reduce fragmentation that has negatively affected space programs for many years. But open questions remain about governance as new programs get underway and whether the changes themselves may result in further fragmentation. For example, it is unclear at this time how the new Space Development Agency will mesh with organizations currently involved in testing and acquiring new space technologies. Having the right resources and know-how . While there is increased attention on funding for space and building the Space Force, new programs can still face resource challenges. DOD has begun over 9 new space programs at a time when it is also seeking increased investments in ships, aircraft, and the nuclear triad, among other programs. Moreover, it is unclear whether DOD has a sufficient workforce to manage its new programs. GAO issued a report earlier this month that found DOD does not routinely monitor the size, mix, and location of its space acquisition workforce. Further, DOD has difficulty attracting and retaining candidates with the requisite technical expertise. GAO recommended that DOD collect and maintain data on its space acquisition workforce. DOD did not concur, but GAO maintains that DOD should have better information on such personnel, especially in light of its proposal for establishing the Space Force. GAO also found in March 2019 that key software-intensive space programs often did not effectively engage users to understand requirements and obtain feedback. GAO recommended, and DOD concurred, that the department ensure its guidance addressing software development provides specific, required direction on the timing, frequency, and documentation of user involvement and feedback.

DOD spends billions of dollars each year on systems to support its key business areas, such as personnel and logistics. For fiscal year 2020, DOD reported that its business system investments are expected to cost about $8.9 billion. GAO has made many recommendations to DOD aimed at strengthening defense business systems management. Further, U.S. Code Title 10, Section 2222 requires DOD to perform activities aimed at ensuring that these investments are managed efficiently and effectively. The National Defense Authorization Act for Fiscal Year 2016 included a provision for GAO to report on the extent to which DOD is complying with the code's requirements. Accordingly, the objective of this review was to assess the extent to which DOD has taken actions that comply with the code's requirements for ensuring that business system investments are managed efficiently and effectively. To do so, GAO selected 12 recommendations that DOD had not implemented as of June 2019, and assessed the department's subsequent actions on the recommendations (through November 2019) against the requirements in the code. GAO also analyzed DOD's business systems guidance and business enterprise architecture documentation, and interviewed relevant DOD officials. As of November 2019, the Department of Defense (DOD) had taken actions that addressed some, but not all, of the 12 prior GAO recommendations for strengthening defense business systems management. In doing so, the department made progress in complying with related business system investment management requirements contained in U.S. Code Title 10 Section 2222 (the code or U.S. Code). Specifically, as of November 2019, DOD had implemented four of the 12 recommendations (see table). For example, with respect to the requirement associated with investment management guidance, DOD had implemented the recommendation to issue policy requiring full consideration of sustainability and technological refreshment requirements for its business system investments. However, DOD had not yet implemented eight other recommendations relating to the code's requirements. The recommendations that had not been implemented relate to the department's actions to: integrate its business and information technology (IT) architectures, ensure that portfolio assessments are conducted in key areas identified in the GAO Information Technology Investment Management framework. develop a skills inventory, needs assessment, gap analysis, and plan to address identified gaps as part of a strategic approach to human capital planning, among other things. Taking further actions to implement all of the recommendations is essential to helping the department achieve compliance with all of the requirements—and, ultimately, further strengthen the management of its defense business system investments as well as its efforts to effectively transform its business operations.


DOD spends billions of dollars each year to maintain key business operations intended to support the warfighter. The John S. McCain National Defense Authorization Act for Fiscal Year 2019 established requirements for DOD to reform its enterprise business operations. Section 921 of the act required the Secretary of Defense, acting through the Chief Management Officer, to submit to the congressional defense committees by February 1, 2019, a plan, schedule, and cost estimate for reforms of DOD's enterprise business operations to increase effectiveness and efficiency of mission execution. Section 921 also requires GAO to provide a report assessing the feasibility of the plan. GAO's objectives were to assess (1) DOD's 921 plan, including its feasibility in reforming DOD's business operations, and (2) the extent to which DOD has made progress in implementing the plan and its broader reform efforts. GAO reviewed DOD's plan and associated documentation and interviewed DOD officials on efforts to reform business operations of the department, including the development and implementation of the plan. GAO also reviewed its past work on DOD reform efforts and the specific subject areas covered by DOD's reform initiatives. GAO has previously made eight recommendations related to DOD's reform initiatives from three prior reports. DOD concurred with those recommendations and is working to address them, in part through the initiatives GAO discusses. The Department of Defense's (DOD) April 2019 plan for business reform identifies eight initiatives related to civilian resources management, logistics management, services contracting, and real estate management. According to the plan, these initiatives will cost at least $116 million to implement through fiscal year 2021. GAO found that the plan generally contains the elements required under section 921—a schedule and cost estimate—and that several initiatives address aspects of GAO's prior recommendations. However, because many of the planned initiatives entail collecting information that will lay the groundwork for later reforms, assessing the feasibility of DOD's reform effort is difficult. For example, one logistics reform initiative plans to identify opportunities to improve processes, make recommendations, and develop an implementation plan for the recommendations by the end of fiscal year 2019. Although DOD officials told GAO that the department is making progress implementing the plan's initiatives and achieving cost savings on its broader efforts, DOD provided limited documentation of that progress. As a result, GAO could not independently assess and verify this progress. For example: Office of the Chief Management Officer (OCMO) officials provided briefing charts on the status of milestones for DOD's three human resource–related initiatives stating that those initiatives are progressing according to the schedule, but did not provide underlying documentation for each milestone. According to DOD, its broader reform efforts have saved or are expected to save about $18.4 billion between fiscal years 2017 and 2020. According to Under Secretary of Defense (Comptroller) officials, they have validated these savings. However, DOD did not provide any supporting documentation that would allow GAO to independently validate these savings. GAO's prior work has found repeated shortcomings in DOD's ability to demonstrate that it has achieved its goals for savings from reform efforts. DOD is taking steps to address these challenges, including establishing cost baselines for DOD's major lines of business and incorporating Comptroller input into estimates of the costs and potential savings from initiatives as they are developed. Further, according to the plan, DOD has provided funding through its annual budget process for four of the eight initiatives included in its plan. For the four remaining initiatives, OCMO has identified a source of funding but not obtained that funding for two initiatives, is awaiting a cost estimate for one initiative, and has identified only partial funding for one initiative, which is designed to review contracts and categories of goods or services on a quarterly basis to identify savings. OCMO anticipates that savings identified in earlier rounds of this initiative will fully fund later rounds. However, in January 2019, GAO reported that, according to OCMO, DOD initially planned to fund its reform initiatives in part with savings generated by other initiatives, but recognized that this approach did not work because additional funding was needed. GAO recommended that DOD establish a process to identify and prioritize funding for implementing its initiatives. OCMO has updated its processes for managing its reform efforts in part to address this issue, but the effects of this update at this time are unclear.


DOD spends over $300 billion annually on contracts for products and services such as major weapons systems and military support services. By awarding and overseeing these contracts, DOD's acquisition workforce plays a critical role in maximizing DOD's buying power. DOD has increased the size of its acquisition workforce in recent years, but has also faced a number of challenges hiring and retaining personnel. DOD has a number of human capital flexibilities that help DOD in hiring, recruiting, and retaining its civilian acquisition workforce. The National Defense Authorization Act for Fiscal Year 2018 included a provision for GAO to review DOD's implementation of human capital flexibilities for its acquisition workforce. This report: (1) provides information on DOD's use of human capital flexibilities and (2) determines the extent to which DOD has monitored and assessed its use of these flexibilities. GAO reviewed relevant statutes, and DOD policies, guidance, and acquisition workforce plans; analyzed DOD's fiscal year 2014-2018 civilian acquisition workforce personnel data; and interviewed DOD officials. The Department of Defense (DOD) has used human capital flexibilities extensively to hire, recruit, and retain its civilian acquisition workforce. Since 2014, usage rates for hiring flexibilities—alternatives to the traditional, competitive hiring process—have generally increased. DOD leadership has encouraged its hiring personnel to use these flexibilities, such as direct hire authorities, to reduce the length of the hiring process. From fiscal year 2014 to 2018, DOD used hiring flexibilities for 90 percent of its approximately 44,000 civilian acquisition workforce hiring actions (see figure). DOD also increased its use of recruitment and retention flexibilities for its civilian acquisition workforce, increasing the dollar amount authorized from $13.9 million in fiscal year 2014 to $33.7 million in fiscal year 2018. This increase came as DOD leadership emphasized the benefits of these flexibilities, and oversaw concerted efforts to increase their usage through the dissemination of information to human resource specialists. While usage of human capital flexibilities has increased, DOD's Office of Human Capital Initiatives (HCI), which is responsible for DOD-wide acquisition workforce strategic planning, does not regularly monitor or assess how the department uses these flexibilities. HCI regularly monitors the overall health of the acquisition workforce, including by reviewing workforce metrics on a quarterly basis, but does not regularly monitor the military departments' use of human capital flexibilities. For example, GAO found the Air Force and Navy used direct hire authorities twice as often as the Army in fiscal year 2018. Without efforts to gain such insights through monitoring, HCI may be missing opportunities to identify challenges, inconsistencies, or needed improvements in using these tools. With regard to assessing the use of human capital flexibilities, HCI intends to study how long it takes to hire personnel when using the flexibilities. According to DOD officials, this analysis can begin following development of a plan to ensure that defense components consistently collect data on hiring timeframes. DOD officials said they expect to issue this plan in 2019.


DOD's 2018 National Defense Strategy continues the department's shift toward focusing on the challenges posed by major powers—China and Russia. The strategy concludes that DOD must pursue urgent change at a significant scale and starkly warns that failure to properly implement the strategy will rapidly result in a force that is irrelevant to the threats it will face. To implement the change DOD envisions, senior leaders must have quality information. Senate Report 115-125 includes a provision for GAO to review DOD's analytic approach for informing force structure decisions to implement the National Defense Strategy. This report assesses, among other things, whether DOD's analytic approach has provided senior leaders with the support needed. GAO reviewed DOD guidance, assessed whether DOD was meeting the objectives identified in its guidance, and interviewed agency officials. This is an unclassified version of a classified report issued in February 2019. Information that DOD deemed classified has been omitted. The Department of Defense's (DOD) analytic approach has not provided senior leaders with the support they need to evaluate and determine the force structure necessary to implement the National Defense Strategy. DOD's analytic approach—Support for Strategic Analysis (SSA)—is used by the services to evaluate their force structure needs and develop their budgets. However, GAO found that SSA has been hindered by three interrelated challenges: Products are cumbersome and inflexible. Although DOD guidance states that SSA products are to be common starting points for analysis on plausible threats, including threats identified in strategic guidance, DOD has not kept the products complete and up to date in part because they were highly detailed and complex and therefore cumbersome to develop and analyze. Analysis does not significantly deviate from services' programmed force structures or test key assumptions. Although DOD's guidance states that SSA should facilitate a broad range of analysis exploring innovative approaches to mitigate threats identified in the strategy, the services generally have not conducted this type of analysis because guidance has not specifically required the services to do so. DOD lacks joint analytic capabilities to assess force structure. Although DOD guidance states that SSA is intended to facilitate the comparison and evaluation of competing force structure options and cross-service tradeoffs, the department has not conducted this type of analysis because it lacks a body or process to do so. DOD efforts to revise its analytic approach are in the early stages and have not yet identified solutions to these challenges. Moreover, DOD has attempted reforms in the past without success. Without a functioning analytic process that addresses the above challenges, senior leaders do not have the analytic support they need to prioritize force structure investments that would best manage risk and address the threats outlined in the National Defense Strategy.
