The U.S. military has spent an estimated $33.4 billion during the initial four months of its conflict with Iran, dubbed Operation Epic Fury, with a significant portion allocated to munitions. This substantial expenditure has led to critical shortages in key weapons inventories, according to a new report from the Pentagon's Department of War Office of Inspector General. The comprehensive report, released on September 14, covers U.S. government activities from the operation's start on February 28 through June 30.

The inspector general's findings indicate that approximately $22.3 billion of the total $33.4 billion spent during this period was directed toward munitions. The report, which provides the clearest government accounting of the war’s early financial and logistical costs, explicitly warns, "The munitions expenditure on OEF has resulted in strategic inventory shortfalls and revealed industrial base bottlenecks for munitions resupply." This figure, however, does not represent the full cost of the ongoing conflict, as military operations have continued past the June 30 cutoff date. A separate assessment by the Congressional Budget Office (CBO) this week estimated the war's cost at roughly $38 billion as of August 1, with projections of an additional $3 billion per month if operations persist at the current pace.
Beyond financial costs, the inspector general's report also documented extensive physical damage to U.S. military infrastructure and equipment across the Middle East. Hundreds of buildings and other structures at American bases in Kuwait, Bahrain, Qatar, the United Arab Emirates, Saudi Arabia, Oman, and Jordan were reportedly damaged during Iranian attacks. Furthermore, aircraft, drones, and various other military equipment were either destroyed or sustained damage. Associated Press reporting on the watchdog's findings noted that Iranian strikes impacted numerous U.S. aircraft, necessitating adjustments to logistics throughout the region by military officials.
The warning regarding munitions comes amidst an ongoing public debate concerning the condition of U.S. weapons stockpiles. President Donald Trump has consistently dismissed suggestions that the United States is experiencing a shortage of weapons. In a recent social media post, President Trump stated, "The United States is producing more Exquisite and Elite Weapons than at any time in our History," adding that new weapons were being delivered to U.S. forces operating in the Middle East. Defense Secretary Pete Hegseth has also previously disputed reports indicating serious shortages in the nation's defense supplies.
However, the inspector general’s assessment directly contradicts these assertions, specifically identifying "strategic inventory shortfalls" and "production bottlenecks" that impede the military’s capacity to rapidly replace weapons utilized in combat. Among the advanced systems facing significant pressure are Patriot and Terminal High Altitude Area Defense (THAAD) interceptors, which have been heavily deployed to defend U.S. and allied positions against incoming Iranian missiles. While the Pentagon is actively collaborating with defense manufacturers to boost production and replenish inventories, the report highlights that manufacturing some advanced missile systems in large quantities can require several years. The report underscores a critical challenge in maintaining readiness while sustaining prolonged military operations.
