U.S. Military Maintenance Backlog Exceeds $285 Billion

A GAO report warns that the backlog of maintenance at U.S. military facilities has surpassed $285 billion, as bases face mold, asbestos, leaks, HVAC failures, and inadequate services for their troops.

• The maintenance backlog grew from about $137 billion in 2022 to over $285 billion in fiscal year 2025.
• The GAO highlighted issues of mold, asbestos, water damage, HVAC failures, and emergency exit doors in several facilities.
• The White House proposed a defense budget of $1.5 trillion for fiscal year 2027.

The backlog of maintenance at U.S. military facilities exceeded $285 billion in fiscal year 2025, according to a report from the Government Accountability Office (GAO). The document warns that the deterioration affects both operational readiness and the quality of life for service members, at a time when the White House proposed a defense budget of $1.5 trillion for fiscal year 2027.

The figure represents a significant jump from the approximately $137 billion accumulated in 2022. The growth of the backlog contrasts with the expansion of Department of Defense spending and raises an uncomfortable question about resource allocation: how can the overall budget increase while essential facilities continue to operate with issues of moisture, climate control, security, and service capacity?

A Backlog That Continues to Grow

The GAO attributes part of the increase to the armed forces requesting about 80% of the funds they need for repairs and maintenance of their facilities. This gap between calculated needs and requested resources leaves a significant portion of projects unfunded, allowing deficiencies to accumulate and raising the cost of future interventions.

The report concluded that by requesting less money for maintenance and facility improvement projects than their models and experts recommend, the Department of Defense has chosen to accept a certain level of risk. According to the assessment, this risk could negatively affect mission performance or the quality of life for personnel, two areas that are typically presented as priorities for military infrastructure.

The problem is not limited to aesthetic repairs or aging buildings that require gradual renovation. The office’s observations include conditions that could interfere with an emergency, expose occupants to hazardous materials, or hinder soldiers from receiving basic services in a timely manner.

The accumulation also reveals the effect of postponing budgetary decisions year after year. When a facility operates with leaks, HVAC failures, or water damage, a minor repair can turn into a larger project, while personnel continue to work or live in a deteriorated environment.

Mold, Asbestos, and Risks in Facilities

At the Norfolk Naval Station barracks, there has been a suspicion of mold since 2023, but the facility’s office rejected requests to analyze the observed growth. The explanation given was the cost of analysis and potential remediation, a decision that left the nature of the problem unconfirmed in a space used by service members.

The situation in Norfolk did not end with that suspicion. The GAO found that another heavily used facility on the station showed evidence of asbestos and significant water damage, while all the docks in the complex required renovation and the Navy was only actively improving one of them.

The rest of the docks were to continue operating in a degraded condition, according to the description gathered in the report. The finding shows that the deficit not only affects dormitories or administrative spaces but also infrastructure linked to naval operations and the continuity of activities at a high-use station.

At a facility of the Naval Base in Guam, investigators observed rust and algae accumulation on the lock of an emergency door. The GAO noted that this condition could affect the door’s functionality during an emergency, turning a maintenance failure into a potential obstacle to personnel safety.

The same base faces other recurring problems, including failures in heating, ventilation, and air conditioning systems, identified by the acronym HVAC, as well as leaks in the roofs. These deficiencies have raised suspicions of mold, which expands the impact from physical infrastructure to the environmental conditions of the occupied spaces.

Quality of Life Also Exposed

The report links delayed maintenance to everyday problems that directly affect service members. At Fort Wainwright, around 3,000 soldiers live on the installation, but the dining facility was built to serve only 800 people, a difference that limits the ability to provide food at necessary times and conditions.

The GAO found that the dining facility cannot serve soldiers in a timely manner, leading many to opt for less healthy food in their usual spaces and bear the cost themselves. The situation becomes especially difficult during winter when low temperatures make it too uncomfortable to wait outside in line.

Officials have repeatedly defended the expansion of the dining facility, but Fort Wainwright has yet to receive the necessary funds to execute the project. The lack of capacity, therefore, does not appear as an unknown need but as an identified shortcoming that continues without sufficient budgetary response.

This case allows us to see how an infrastructure failure can have consequences that go beyond the building where it occurs. The insufficiency of the dining facility influences soldiers’ eating habits and personal expenses, while housing, humidity, or climate issues can deteriorate their well-being during tasks and rest periods.

The central concern of the report is that these deficiencies end up normalizing within facilities that must sustain military readiness. If the requested resources cover only part of the estimated needs, the Department of Defense maintains the ability to prioritize some projects but also retains an increasing volume of risks in the places that remain outside that selection.

More Budget, but a Persistent Gap

The maintenance backlog continues to grow despite the increase in the Pentagon’s budget. The White House proposed USD 1.5 trillion for defense in fiscal year 2027, a figure that makes the contrast between the total spending volume and the conditions documented in Norfolk, Guam, and Fort Wainwright more visible.

The size of the budget does not guarantee that facilities receive the resources they require. The GAO itself indicated that the armed forces submit requests lower than the needs recommended by their models and experts, so the debate is not limited to how much money exists but to which projects are included and which are postponed.

The difference between a partial request and a calculated need can have cumulative consequences. A base that postpones the renewal of several docks, the analysis of potential mold, or the repair of roofs and HVAC systems may later face a combination of operational risks, higher costs, and less suitable living conditions for personnel.

The available information does not establish that every observed problem has caused an interruption of operations, nor that all military installations are experiencing identical conditions. However, the examples selected by the GAO show that pending maintenance is already manifesting in concrete risks, from a potentially compromised emergency door to insufficient spaces to accommodate soldiers.

The report places the Department of Defense in a budgetary and operational dilemma: to continue accepting part of the risk to direct resources to other priorities or to elevate requests aimed at infrastructure. While that response is being defined, bases will continue to depend on decisions that will determine whether pending repairs decrease or grow again during the next fiscal cycles.

The contradiction highlighted by the case is hard to ignore: a large-scale military budget proposal coexists with facilities that cannot resolve basic issues of moisture, safety, and service capacity.
