The U.S. Department of Defense Inspector General reported that the conflict with Iran has resulted in "strategic inventory shortfalls" of munitions and created bottlenecks in the resupply chain. The findings, released by the independent watchdog, state that the U.S. spent more than $22 billion on munitions between February and June. This assessment contradicts statements from President Donald Trump, who has described U.S. supplies as "virtually unlimited" and dismissed reports of shortages as inaccurate.
The report offers an independent view of U.S. weapons stockpiles, which are generally classified. While it did not disclose the exact number of weapons remaining, the inspector general noted that the Department of Defense is currently attempting to shorten production lead times and streamline procurement to address these gaps. The watchdog also reported $3.7 billion in equipment losses and $7.4 billion in other expenditures, totaling $33.4 billion spent on the war from February 28 to June 30.
The White House and administration officials have rejected the findings. White House spokeswoman Anna Kelly stated on Tuesday that the military maintains sufficient stockpiles to meet strategic goals. Defense Secretary Pete Hegseth also described reports of shortages as "not true" in an August 4 social media post. However, other estimates support the watchdog's concerns; a July study by the Center for Strategic and International Studies (CSIS) suggested that stocks of certain interceptors, including Patriot and THAAD missiles, had been depleted in some cases by more than half.
This report highlights a $33.4 billion expenditure over a four-month period. The Congressional Budget Office (CBO) provided an estimate of $38 billion when accounting for fuel costs, increased flying hours, and the replacement of destroyed equipment. The reported losses include four F-15e fighter jets, one F-35 Joint Strike Fighter, and 30 MQ-9 drones.
The "industrial base bottlenecks" mentioned by the inspector general mean that if a new military contingency arises, the U.S. may face delays in acquiring necessary hardware. The depletion of interceptors like the Patriot and THAAD systems—used to stop incoming attacks—specifically affects the defensive capabilities of U.S. forces and allied nations relying on U.S. supply chains.
The political implications are tied to the timeline of the conflict and public perception. While President Trump initially stated the conflict would conclude within weeks, he recently suggested it may continue until after the November midterm elections. A Reuters/Ipsos poll indicated that 23% of Americans believe the U.S. is in a stronger position regarding Iran than before the hostilities. The Department of Defense is now tasked with responding to the inspector general's findings by adjusting its production schedules, though no specific deadline for full inventory replenishment was provided in the report.
