The first quarterly report by the Pentagon’s Lead Inspector General evaluating Operation Epic Fury confirmed that extensive munitions usage during the four-month military campaign against Iran resulted in strategic inventory shortfalls and highlighted severe constraints within the United States defense industrial base.
Covering the reporting period from April 1 through June 30, the oversight document cited evaluations from the Office of the Under Secretary of War for Acquisition and Sustainment indicating that current consumption rates have created gaps in strategic stockpiles. To mitigate these shortfalls, military acquisition authorities are attempting to streamline procurement protocols, shorten manufacturing lead times, and build emergency reserves of raw materials, key components, and high-demand munitions. However, the report emphasized that expanding defense industrial production capacity requires significant lead time, identifying critical bottlenecks in the manufacturing of solid rocket motors, the procurement of high-grade propellants and energetic explosives, and the recruitment of specialized technical labor.
Financial Toll and Discrepancy with Official Statements
The inspector general's findings contrast with previous public statements from senior White House and military officials downplaying stockpile concerns. President Donald Trump and Defense Secretary Pete Hegseth have repeatedly rejected assertions regarding depleted weapon reserves, with the administration asserting that the domestic manufacturing base was producing record quantities of advanced weaponry.
According to the official accounting, the total financial cost of the conflict reached $33.4 billion as of June 29. This total includes $22.3 billion in expended munitions, $3.7 billion in military equipment losses evaluated at replacement cost, and $7.4 billion in direct operational expenses. The calculation excludes structural repair costs for damaged regional military infrastructure. Addressing budget pressures, Secretary Hegseth warned lawmakers in July that without emergency supplemental appropriations, the Defense Department faced severe funding gaps that could impact military payrolls, equipment replenishment, and broader global operations. The White House subsequently submitted an $87.6 billion emergency funding request to Congress, including $67.1 billion for military operations and $21 billion dedicated specifically to munitions procurement.
Casualties and Operational Losses
The oversight report detailed significant human and material losses sustained during the campaign. Between February 28 and June 30, seven United States service members were killed in combat, seven died in non-hostile incidents, and 417 were wounded in action. Four additional combat fatalities were recorded in July.
Material losses included four F-15E strike fighters, an F-35A Joint Strike Fighter, an A-10 Thunderbolt II, 12 KC-135 refueling tankers, and approximately 30 MQ-9 unmanned aerial vehicles damaged or destroyed under combat conditions. The report also provided formal confirmation that Iranian ballistic missiles and attack drones damaged major American logistics infrastructure in the region, including facilities in Bahrain, while inflicting over $208 million in damage and delay costs across Department of State installations in the Middle East.
