U.S. Munitions Expenditure and Stockpile Strain in Operation Epic Fury

Operation Epic Fury’s Cost and Weapon Use
The Pentagon inspector general’s report released in late June estimates that Operation Epic Fury, which began on February 28, has cost $33.4 billion through June 30, with $22.3 billion attributed to expended munitions. U.S. forces have struck more than 13,000 Iranian targets, employing cruise missiles, air-launched missiles, and ground-based launchers, while also firing high-end interceptors to counter Iranian missiles and drones. The conflict has resulted in the loss of four F-15 fighters, one damaged F-35, seven KC-135 tanker aircraft, and up to 30 MQ-9 Reaper drones. The inspector general also recorded $3.7 billion in equipment losses overall.
Stockpile Shortfalls and Industrial Bottlenecks
According to the same report, the high rate of munitions expenditure has created “strategic inventory shortfalls” and exposed “industrial base bottlenecks” that hinder rapid resupply. The Center for Strategic and International Studies (CSIS) warned that key systems such as Tomahawk land-attack cruise missiles and interceptors launched from Terminal High Altitude Area Defense (THAAD) and Patriot batteries will take years to return to pre-war inventory levels. The inspector general recommended that the Pentagon streamline procurement processes, shorten production lead times, and stockpile critical components to mitigate future shortages.
Official Responses
Admiral Brad Cooper, head of U.S. Defense Secretary Pete Hegseth has publicly urged the defense industry to accelerate weapons manufacturing, a sentiment echoed by Lockheed Martin’s missile-division head Tim Cahill, who described the production environment as “controlled chaos.”
Concerns About Future Conflict Readiness
CSIS analyst Mark Cancian indicated that while the United States can sustain a war against Iran, a prolonged conflict with a near-peer adversary such as China would strain munitions supplies beyond the first month. CSIS experts also noted that analyses prior to the war already highlighted a need for larger inventories, and that Operation Epic Fury has intensified a multiyear rebuilding effort.
Additional Financial Impacts
Beyond weapons spending, the State Department incurred $79.2 million for evacuation-related contingencies and estimated $184 million to repair damage to diplomatic facilities in Iraq, Kuwait, Saudi Arabia, and the United Arab Emirates. Damage to U.S. bases across the Gulf region remains extensive, with repair costs and responsibility for reconstruction still uncertain.
