What GAO Found
Navy and Coast Guard shipbuilding programs have consistently fallen short of expectations over the last 2 decades. Collectively, they are billions of dollars over cost and years behind schedule. For example, the Navy’s Constellation class frigate program was overcome by issues. As a result, the Navy announced a strategic shift away from the program in 2025—having previously exercised contract options valued at over $3 billion dollars. Similarly, the Coast Guard paused work on two ships and terminated two other ships in its Offshore Patrol Cutter program after a more than 5-year delay in delivering the lead ship.
Constellation Class Frigate and Offshore Patrol Cutter
Proposed solutions by federal officials have included reorganizing how shipbuilding programs are managed, increasing shipbuilder workforce wages, and finalizing ship designs before beginning construction, among others. While there is no singular solution, implementing leading practices and GAO’s prior recommendations could help ensure smoother sailing.
For example, ensuring that new ship design efforts, such as the Navy’s planned new attack submarine program, fully leverage ship design practices used by leading companies will be critical to long-term success. This would include practices like iterative design based on user feedback, completing ship design before beginning construction, and using digital tools. (See GAO-24-105503.)
Additionally, the shipbuilding industrial base—the private companies that build or supply the parts for ships—has not met the government’s submarine construction goals in recent years. GAO’s analysis of the Department of Defense’s (DOD) efforts to invest in the submarine industrial base to improve its capacity found shortcomings. For example, DOD does not know how much funding it expects to need—beyond the more than $10 billion DOD already invested—to solve submarine industrial base challenges such as ensuring needed parts get delivered on time. Without this understanding, decision-makers may not have the information needed to balance funding for the submarine industrial base with other shipbuilding priorities. Further, DOD has not taken key steps to ensure oversight for some of its costliest submarine industrial base investments. Without improvements, such as documented project monitoring, DOD cannot ensure those taxpayer dollars are helping achieve its goals as cost effectively as possible. These findings can provide lessons learned for the Navy, Coast Guard, and other federal agencies in their efforts to build up the maritime industrial base.
Why GAO Did This Study
The U.S. is in a period of heightened emphasis on improving shipbuilding to tackle pressing national security demands. The Navy and Coast Guard spend billions to procure ships each year and have ambitious plans to build new ships. GAO has reported for decades on the persistent issues that plague these shipbuilding programs and has made more than 100 recommendations to address them.
This statement addresses (1) the state of Navy and Coast Guard shipbuilding; (2) key challenges the Navy and Coast Guard need to address to achieve their ambitious shipbuilding goals; and (3) DOD’s efforts to support the submarine industrial base and the lessons that can be derived for future maritime industrial base investments.
This statement is based on prior and ongoing GAO work. In addition, GAO is issuing the results of its analysis of DOD’s management of submarine industrial base investments in this testimony statement. To perform this work, GAO analyzed relevant Navy and Coast Guard documentation and interviewed knowledgeable officials.
What GAO Found
The Federal Emergency Management Agency's (FEMA's) Individual Assistance helps survivors of major disasters cover necessary expenses and serious needs that insurance or low-interest loans do not cover. This may include reimbursing survivors for temporary lodging or providing assistance with rental housing and home repairs. In response to Hurricanes Helene and Milton, the 2025 Los Angeles (LA) wildfires, and the 2025 Texas floods, FEMA provided over $3 billion to 1.2 million individuals and households, according to agency data.
FEMA has made changes to improve the implementation of its assistance to survivors. For example, FEMA has simplified application requirements and increased eligibility for certain assistance. However, GAO found that survivors continued to face challenges communicating with FEMA and securing post-disaster housing. For example:
Reaching FEMA's helpline. FEMA data show that most survivors affected by Hurricanes Helene and Milton and the Texas floods faced long wait times and could not reach a representative when trying to apply for assistance through FEMA's helpline.
Understanding FEMA's letters. Some survivors faced challenges interpreting letters from FEMA regarding their eligibility for assistance. For example, some survivors thought letters requesting more information were denial letters, according to FEMA and state officials. FEMA revised its letters in 2024 and 2025 to incorporate more plain language and clearer instructions.
Securing post-disaster housing. Survivors of recent disasters and officials from all levels of government experienced long-standing housing challenges. For example, FEMA officials said that it was challenging for the agency to support post-disaster housing for survivors after Hurricane Helene destroyed many of the housing resources that were already constrained before the storm hit. Additionally, FEMA officials reported issues that delayed the agency's ability to provide direct housing—such as needing to set up septic tanks and energy meters before making manufactured housing units available.
At the direction of the current administration, FEMA made recent changes that affect its delivery of assistance to survivors. This includes focusing on providing support at state or local centers, thereby reducing the need for FEMA to establish its own Disaster Recovery Centers where applicants can obtain information and apply for benefits. In addition, FEMA has discontinued its door-to-door canvassing efforts. However, some FEMA and state officials expressed concerns about how this could affect their ability to support survivors who may not be able to access an in-person recovery center, including those who are older, have disabilities, live in rural areas, or lack phone or internet access.
State and local capacity to provide assistance to survivors will significantly impact the implementation of these and other potential changes to FEMA's delivery of assistance. For example, officials from four states affected by Hurricanes Helene and Milton told GAO they do not have their own individual assistance programs for survivors after a disaster. In addition, federal and state officials emphasized the need for adequate time for state and local governments to prepare for any changes in disaster response roles since they currently rely on significant federal support.
Why GAO Did This Study
The extensive damage caused by recent natural disasters, including Hurricanes Helene and Milton in 2024, the LA wildfires in 2025, and the July 2025 floods in Texas, demonstrates the need for government-wide action to deliver assistance efficiently and effectively.
GAO has previously reported that disaster survivors have faced numerous challenges receiving aid from FEMA—the lead agency for federal disaster response. This includes challenges understanding and navigating the assistance process that may have prevented survivors from receiving assistance for which they may have otherwise been eligible. Further, improving processes for assisting survivors is one of the key challenges identified in GAO's High-Risk List on Improving the Delivery of Federal Disaster Assistance.
Congress and the President have signaled an interest in enacting reforms to FEMA. For example, in January 2025, the President established a FEMA Review Council to assess FEMA's disaster response efforts, recommend improvements to the agency, and review existing reform proposals. GAO was asked to review long-standing challenges and emerging issues in federal response efforts for recent disasters. This report, the third in a series, provides information on FEMA's assistance to disaster survivors and related challenges.
GAO reviewed FEMA information on Individual Assistance—including data on the amount of assistance provided and the number of calls to FEMA's helpline, and eligibility letters to survivors. GAO also analyzed information from 56 interviews and written responses from FEMA and state and local governments impacted by disasters in recent years.

What GAO Found
Every year, Congress appropriates funds to support federal activities and address national priorities. Congress generally appropriates funding, or budget authority, to an agency for use during a specific period, known as the period of availability. The Consolidated Appropriations Act, 2023 authorized trillions of dollars to federal agencies to obligate, or commit to pay for goods and services, during fiscal year 2023 and beyond.
GAO found that 156 of the 258 appropriation accounts in GAO’s review of the Consolidated Appropriations Act, 2023 had budget authority available for obligation in fiscal year 2026 or later, as of September 30, 2025. These accounts had approximately $20.9 billion in unobligated budget authority, or about 1.97 percent of the approximately $1 trillion initially appropriated that had a period of availability of fiscal year 2026 or later. The unobligated budget authority is unexpired, and is comprised of multiple periods of availability (see table).

Detailed information about the amount of unobligated budget authority by appropriation account is in a downloadable dataset, which can be accessed via a link on this page.
Why GAO Did This Study
GAO was asked to identify any remaining budget authority provided in the Consolidated Appropriations Act, 2023 that is unexpired and still available for obligation. This report provides information on these amounts still available to selected agencies to obligate in fiscal year 2026 or later, and key characteristics, such as the appropriation account name; type of budget authority; and the associated programs, projects, or activities.
To conduct this work, GAO reviewed the Consolidated Appropriations Act, 2023 to select the 10 federal agencies with the largest amount of budget authority potentially available for obligation in fiscal year 2026 or later. These agencies are the Departments of Agriculture, Defense, Energy, Health and Human Services, Homeland Security, Housing and Urban Development, Justice, Transportation, and Veterans Affairs, and the Social Security Administration, and represent 258 appropriation accounts that included budget authority available for obligation in fiscal year 2026 or later.
GAO used a data collection instrument to collect the amount of unobligated budget authority from the Consolidated Appropriations Act, 2023 in each appropriation account and related information from the 10 selected agencies. In some cases, GAO conducted follow-up interviews with agency officials to gain additional clarity on the data and information they provided. GAO analyzed the data to calculate summary statistics and to populate a downloadable dataset.

What GAO Found
GAO has designated Medicare a high-risk program due, in part, to its complexity and potential for fraud. Fraud schemes in traditional Medicare often focus on certain services, such as durable medical equipment. Fraudsters may use stolen or inappropriately obtained Medicare beneficiary identifiers to submit fraudulent claims for unneeded or never provided services.
The Centers for Medicare & Medicaid Services (CMS), which oversees Medicare, uses data analytics on claims in traditional Medicare to identify anomalous patterns indicative of emerging fraud schemes and potentially fraudulent behaviors, such as billing spikes. CMS uses these analytics to develop leads for investigations and to inform administrative actions that can prevent potentially fraudulent payments, such as suspending provider payments. For example, in 2023 and 2024, CMS suspended payments to, and later revoked the enrollment of, 15 providers involved in a scheme that allegedly billed Medicare for more than $4 billion in urinary catheters that were never supplied. Selected private payers GAO spoke with reported using data analytics in ways similar to CMS—namely, to identify anomalous provider billing patterns to generate leads for investigations and to inform actions like payment suspensions.
CMS estimates that from fiscal years 2022 through 2024, it prevented a total of $11.9 billion in potentially fraudulent Medicare payments by taking administrative actions on providers engaged in potential fraud.

aProjected amount of potentially fraudulent payments prevented based on estimated cost avoidance.
bEstimated amount in financial judgments that courts may order on behalf of Medicare.
In December 2025, CMS began sharing information about Medicare provider payment suspensions with supplemental payers—private plans and state Medicaid agencies that cover certain Medicare beneficiaries’ out-of-pocket expenses. CMS did not share such information previously. This lack of information sharing led some supplemental payers to pay beneficiary cost sharing on potentially fraudulent claims. Representatives of private payers estimated that private plans may have paid tens of millions of dollars in beneficiary cost-sharing for the urinary catheter scheme. GAO’s analysis found that state Medicaid agencies paid at least $196,000 in state and federal funds for cost-sharing payments for the urinary catheter scheme in 2023 and 2024.
Why GAO Did This Study
CMS is responsible for ensuring the integrity of the Medicare program and preventing and mitigating potential fraud.
GAO was asked to review CMS’s use of data analytics to prevent and reduce fraud in traditional Medicare. This report describes characteristics of common Medicare fraud schemes, CMS’s use of data analytics to identify Medicare fraud, and CMS’s estimates of potentially fraudulent payments it prevented; and examines the extent to which CMS shares information on payment suspensions with relevant entities.
GAO reviewed CMS documentation on its activities to prevent fraud and interviewed CMS officials and program integrity contractors that investigate Medicare fraud about common Medicare fraud schemes and their use of data analytics. GAO also analyzed CMS data on administrative actions and the extent of potentially fraudulent payments prevented for fiscal years 2022 through 2024. Data from 2024 were the most recent data available at the time of GAO’s review.
For additional context on CMS’s use of data analytics, GAO interviewed representatives of selected private health insurers and two organizations representing private payers about their use of data analytics. GAO also interviewed CMS officials and private payers about the sharing of information on payment suspensions with supplemental payers.
The Department of Health and Human Services provided technical comments, which GAO incorporated as appropriate.

What GAO Found
The Infrastructure Investment and Jobs Act of 2021 (IIJA) required the U.S. Department of Transportation (DOT) to establish the Office of Multimodal Freight Infrastructure and Policy (Multimodal Freight Office, or Office). Its responsibilities include coordinating with other agencies, states, and the private sector; assisting cities and states to improve freight mobility; and carrying out the goals of the national multimodal freight policy.
The IIJA directs the Multimodal Freight Office to administer certain policies and programs, such as developing and managing the National Freight Strategic Plan and the National Multimodal Freight Network, which connects highways, railroads, and maritime routes. DOT has taken steps toward meeting almost all of its statutory requirements. For example, DOT plans to release an updated National Freight Strategic Plan in 2026 and is updating the National Multimodal Freight Network.
U.S. National Multimodal Freight Network
DOT has not completed one of the office’s statutory requirements–periodically reporting to Congress on the activities of the Multimodal Freight Office. Officials stated that the Office had not done so because it had limited staff and was focused on other activities. While the Office briefed congressional staff in 2023, without periodic reporting, Congress has limited visibility into the activities the Office has conducted since then. Having recent information is important as Congress considers how the Office could support federal surface transportation programs, and any potential legislation related to the upcoming reauthorization.
To prevent potential duplication when forming the Multimodal Freight Office, DOT formed a task force in 2023 to review multimodal freight responsibilities across the department. The task force established complementary roles between the office and other DOT administrations, according to DOT officials. DOT officials and transportation industry associations GAO met with said they found the Office helpful as a single point of contact able to respond to freight-related incidents and could help address freight issues, such as the nationwide shortage of truck parking for commercial drivers.
Why GAO Did This Study
The U.S. freight transportation network is vital to the nation, moving over 20 billion tons of freight in 2024 over an extensive, interconnected network. DOT is responsible for ensuring the safe, efficient, and reliable movement of freight over this network. The IIJA included a provision for GAO to review the activities of the Multimodal Freight Office.
This report examines (1) the progress DOT has made in meeting its statutory requirements related to the Multimodal Freight Office and (2) how DOT identified and managed any areas of duplication and improved efficiency for freight issues across the department when establishing the Multimodal Freight Office.
GAO interviewed DOT officials on steps taken toward meeting the statutory requirements. GAO analyzed internal DOT documents on the agency’s activities to manage any duplication and improve efficiency in multimodal freight efforts when establishing the Multimodal Freight Office. GAO also interviewed DOT operating administration officials; four stakeholders from the trucking, railroad, air, and maritime freight transportation industries; and one state transportation association on their views on activities of the office. GAO selected these stakeholders, as they represent the major modes of freight transportation in the U.S., per DOT’s draft National Multimodal Freight Network.
What GAO Found
Several factors limit the operations of Guam’s Customs and Quarantine Agency (CQA). For example, CQA maintains only paper-based records of customs transactions, which officials said limits efficiency, may compromise data reliability and result in reduced revenue. In August 2025, CQA received funding to implement an automated customs system. Nonfunctional equipment and procurement delays also limit CQA’s operations. For the past 3 years, CQA has had only one working x-ray machine, resulting in time-intensive manual cargo inspections.
GAO identified several considerations for evaluating three selected alternatives to Guam’s current customs model: (1) Guam joins the U.S. customs territory, with U.S. Customs and Border Protection (CBP) administering Guam customs (federalized model); (2) Guam remains outside the U.S. customs territory, with CBP administering Guam customs (hybrid model); or (3) Guam retains its current customs model, with additional funding for CQA from higher fees for incoming passengers or cargo. Considerations include the following:
Legal changes and funding sources. In the federalized model, federal law would have to be amended for Guam to join the U.S. customs territory. In the federalized or hybrid model, a source of funding for CBP operations in Guam would need to be identified.
Jurisdiction and security. In the federalized model, CBP would not inspect cargo from the U.S. customs territory. CQA officials said this could increase the risk of illegal drugs entering Guam, as most are smuggled from other parts of the U.S. Also, in the federalized model, Guam’s ports would need to be upgraded to meet all federal security requirements.
Changes to Guam’s current customs model could also affect Guam’s economy. In the federalized model, imports from foreign countries would be subject to U.S. tariffs, while Guam currently does not impose tariffs. Because manufacturing in Guam is limited, this would likely raise the prices of goods on the island. In Guam’s current model with additional funding for CQA, raising passenger fees to increase CQA funding would likely reduce the number of travellers from some countries to Guam. This, in turn, would likely reduce tourism revenue, which is vital to Guam’s economy.
Potential Economic Effects if Guam Adopts One of Two Selected Alternative Customs Models
Why GAO Did This Study
Guam, a U.S. territory in the Indo-Pacific, serves as a strategic U.S. shipping and military hub. Being outside the U.S. customs territory, Guam is not subject to U.S. federal customs administration and may impose its own tariffs on imports. CQA, which administers Guam’s customs operations, is intended to fund its operations through fees collected from incoming passengers and for cargo imports. However, a drop in tourism since 2020 has reduced its revenue.
GAO was asked to examine CQA’s operations as well as alternatives to Guam’s current customs model. This report describes (1) factors that limit CQA’s operations, (2) considerations for evaluating selected alternative customs models for Guam, and (3) potential economic effects if Guam adopts one of the selected alternative models.
GAO analyzed documents provided by Guam and U.S. agencies. GAO also interviewed agency officials and stakeholders in Washington, D.C.; Guam; Puerto Rico; and the U.S. Virgin Islands (USVI). GAO selected Puerto Rico and USVI to examine customs models used in other U.S. territories. CBP administers customs in Puerto Rico, which is in the U.S. customs territory and therefore uses U.S. tariffs. CBP also administers customs in USVI, which is not in the U.S. customs territory and sets its own tariffs. GAO analyzed these models, as well as Guam’s current model with additional CQA funding, as possible alternatives for Guam customs operations. GAO also conducted economic analyses to estimate the effects of Guam’s adopting one of the selected models. In comments on a draft of this report, the Office of the Governor of Guam and CQA raised concerns about the scope of GAO’s review. GAO believes its scope was appropriate to answer the report’s objectives.

What GAO Found
The Veterans Health Administration’s (VHA) Caregiver Support Program offers mental health support, among other benefits, to eligible caregivers who provide around the clock care for veterans with serious injuries. This includes support groups and respite care. In fiscal year 2025, VHA data show the program served about 98,000 caregivers. In addition, VHA obligated $2.6 billion to implement the program, according to officials. VHA officials told GAO the program has grown significantly since fiscal year 2021 due in part to expanded eligibility criteria that allowed more caregivers to participate as of October 1, 2020.
Caregivers Participating in Veterans Health Administration Caregiver Support Program, Fiscal Years 2021 Through 2025
VHA advertises the Caregiver Support Program through various methods, such as email updates and brochures at Department of Veterans Affairs (VA) medical centers. Some caregivers GAO interviewed said they learned about the program through these methods. However, they wished they had learned about it sooner. They also felt other caregivers did not know about the mental health support available to them through the program.
VHA established four goals to assess whether its outreach efforts are effective at increasing caregivers’ awareness of the program. One goal is to increase program enrollment by 15 percent each fiscal year. However, the other three goals, such as increasing subscribers to its email updates, do not have quantitative targets and time frames. Setting targets and time frames for these goals would better enable VHA to measure its progress in increasing awareness of the program among caregivers who are not enrolled, help the agency assess how well its outreach efforts are working, and make any needed adjustments.
VHA has also taken steps to assess how the program supports caregivers by establishing a goal to increase telehealth appointments by 10 percent in fiscal year 2025. VHA collects data on these appointments, which increased by 50 percent from fiscal year 2024 to 2025. However, the agency has not established goals and collected related data for other program services, such as other types of mental health treatment. Setting goals and collecting more complete information would better position VA to assess program performance. VHA could make any needed adjustments to further support caregivers’ wellbeing, allowing it to better support veterans.
Why GAO Did This Study
Several factors, including the demands of their care duties, can affect caregivers’ mental health and wellbeing. Research suggests that such caregiving can be linked to high levels of stress and burden and can result in depression or anxiety.
The Senator Elizabeth Dole 21st Century Veterans Healthcare and Benefits Improvements Act includes a provision for GAO to review mental health support provided by the VHA Caregiver Support Program. This report examines VHA’s efforts to make caregivers aware of the mental health support available to them and VHA’s efforts to assess program performance, among other objectives.
GAO reviewed VHA documentation and data for fiscal years 2021 through 2025. GAO also interviewed VHA officials, program staff and selected caregivers at four VA medical centers, and representatives from four organizations serving veterans and caregivers. GAO selected the medical centers based on program size, geography, and rurality. GAO selected organizations that focus on caregivers and have national reach. GAO also conducted a literature search and review of relevant research.
What GAO Found
For about a quarter of the major rules issued from January 21, 2021, to January 20, 2025 (119 of 462 rules), agencies published effective dates inconsistent with the Congressional Review Act’s (CRA) 60-day waiting period. The waiting period begins when the Federal Register has published the rule or the House and the Senate have received paper copies, whichever is later, and does not apply under certain exceptions, such as when agencies claim good cause.
Example of 60-Day Delay for a Major Rule
The CRA requires rules to be received by Congress but does not further define what constitutes receipt by Congress or establish what must occur for the House and the Senate to receive a rule. Officials from all four agencies described challenges with understanding what counts as the date Congress receives copies of rules. Amending the CRA to be more precise about the date of receipt, such as by specifying that receipt occurs when agencies deliver rules to an identified office or location, would help allay the confusion agencies face. Doing so would promote the CRA’s goal of ensuring a specific minimum delay in the effective dates of major rules.
Department of Energy (DOE) officials told GAO that they set effective dates for some major rules at 75 days from the date of publication in the Federal Register, instead of 60 days, which allows Congress additional time to process and receive the rules. However, no department policy formalizes this practice. GAO found that both DOE and the Department of the Treasury could have increased the number of major rules with effective dates consistent with the CRA by routinely allowing this additional time.
The Department of Health and Human Services (HHS), unlike the other selected agencies, sometimes uses a different date to start the clock on the 60-day delay period. HHS officials told GAO that for some rules, they set the effective date 60 days from the date the Federal Register displays a version of the rule for public inspection, instead of using the date of official publication, as the CRA requires. HHS officials stated they did so because these rules are long and complex and can take weeks to process for publication. As a result, Congress had less time to consider these rules before they were put into effect.
Why GAO Did This Study
Under the CRA, rules that are likely to have large economic impacts (major rules) are subject to a 60-day waiting period before they can take effect. In previous reports, GAO found that agencies frequently set effective dates (i.e., the dates when rules are to take effect) earlier than allowed by the CRA.
GAO was asked to examine agencies’ implementation of the CRA’s 60-day delay for major rules. This report examines, among other issues, (1) the number of major rules issued from January 21, 2021, to January 20, 2025, with stated effective dates inconsistent with the CRA; and (2) challenges selected agencies experienced in setting dates consistent with the CRA.
GAO identified rules with stated effective dates inconsistent with the CRA using its major rule reports, the Federal Register, and the Congressional Record. GAO selected four agencies with the largest number of rules that were inconsistent with the CRA—the Department of Agriculture, DOE, HHS, and Treasury. GAO reviewed documentation and interviewed agency officials on their policies and challenges they may have experienced.
