Independent report contradicts Trump’s ‘virtually unlimited’ munitions claim
The Defense Department’s inspector general confirmed in a newly released report that the war with Iran has produced “strategic inventory shortfalls” in munitions and “industrial base bottlenecks” in resupply, findings that contradict President Donald Trump’s repeated assertions that U.S. weapons supplies are “virtually unlimited.”
The report covers the period from February 28 through June 30, 2026, and provides a first-of-its-kind, independent glimpse into weapons stockpiles typically classified. It documented that the U.S. spent more than $22 billion on munitions during the four-month period. The inspector general did not disclose exactly how many weapons remain.
BBC reporting notes that previous estimates have “painted a dire picture of the US shortages.” Over the course of the war, U.S. forces have expended vast quantities of both long-range ground-attack systems and the air and missile defenses used to intercept incoming Iranian attacks. A late July estimate from the Center for Strategic and International Studies, or CSIS, found that stocks of some interceptors — such as the Patriot missile and the Terminal High Altitude Area Defense, or THAAD — were significantly depleted, in some cases by more than half.
The inspector general’s report noted the inventory shortfalls and revealed “industrial base bottlenecks” for munitions resupply. It added that the Defense Department is now working to “streamline procurement processes and production lead times” to address the shortages and “respond rapidly to a contingency.”
The findings contradict public statements from the president and Defense Secretary Pete Hegseth. In a Truth Social post on September 3, Trump claimed that the U.S. had “virtually unlimited” amounts of ammunition and was “stockpiling and preparing for any contingency that could happen.” In an X post on August 4, Hegseth described news reporting on the shortages as “not true.” Trump has separately characterized such reporting as “fake news” and, on prior occasions, described reports of shortages as “treasonous.” The BBC has contacted the White House for comment about the discrepancy.
The total cost of the war to U.S. taxpayers reached $33.4 billion (£24.7 billion) through June 30, according to the inspector general’s report. Equipment losses totaled $3.7 billion, with an additional $7.4 billion in other expenditures. The conflict has destroyed four F-15e fighter jets, one F-35 Joint Strike Fighter and 30 MQ-9 drones in “various circumstances.”
Polls show that the war is unpopular among Americans. A Reuters/Ipsos poll released in early September found that only 23% of Americans — and only half of Republicans — believe the U.S. is in a stronger position with Iran compared with before hostilities broke out. When U.S. and Israeli strikes began, Trump repeatedly said that the conflict would be over within weeks. More recently, he said the conflict might not end until “right after” the November midterm elections in the U.S.
The inspector general’s confirmation comes about three months after the administration invoked the Defense Production Act to boost munitions output, as MSI previously reported.
