Pentagon inspector general puts the Iran war at $33.4 billion through June

The Pentagon inspector general on 14 September released its first quarterly report on the war with Iran and put the cost to the Defence Department at about $33.4 billion from 28 February through 30 June. That total excludes repairs to damaged bases. Munitions accounted for $22.3 billion. Equipment losses added $3.7 billion. Other spending added $7.4 billion.

The report is the first official public accounting of Operation Epic Fury, the American name for the campaign that began on 28 February. It draws on the inspector general offices at Defence, State and the former US Agency for International Development. NBC News and the Associated Press, which obtained the document, said it also records the destruction of at least 30 large US drones and more than $200 million in damage to State Department facilities in four countries. More than 20,000 US personnel were displaced during the period.

The industrial finding is the one that clashes with recent White House language. The Office of the Under Secretary of Defence for Acquisition and Sustainment told the inspector general that munitions use has already opened what the report calls strategic inventory shortfalls and has exposed bottlenecks in the defence industrial base. The constraints named in coverage of the document include solid-fuel rocket motors, high-grade explosives and propellants, and a shortage of skilled plant workers. The Pentagon, the report says, is trying to shorten procurement cycles, stockpile critical materials and hold selected munitions for a second contingency.

Two weeks before the report landed, President Donald Trump posted that the United States had virtually unlimited ammunition. Defence Secretary Pete Hegseth has denied that stocks are running short. The inspector general's language is narrower and more specific. It does not say the United States cannot fight the current war. It says consumption has opened gaps and that the plants that refill those gaps cannot keep pace.

Independent tallies published earlier this year pointed the same way. A Council on Foreign Relations note in August said more than 1,500 Patriot interceptors had been fired, leaving fewer than 830 in inventory, and that about 40 percent of the 452 THAAD interceptors on hand at the start of the war had been used. CSIS estimated that replacing Tomahawks fired at Iran could run into late 2030 at current build rates of fewer than 200 a year, and that Patriot and THAAD replenishment would stretch into 2029. Raytheon has said it wants Tomahawk capacity above 1,000 a year. That target is a plan, not a 2026 output figure.

The report also notes that Washington recorded more than $44 billion in emergency and non-emergency military sales during the same four months. Saudi Arabia took the largest share, covering helicopters, munitions support and precision weapons. Sales and consumption can rise together. The inspector general's point is that the US inventory is not a bottomless bin even when the order book is full.

Iran struck the Navy logistics hub in Bahrain, according to the document. Damage to aircraft, runways and diplomatic posts across the Gulf is listed but not fully itemised in the public summaries. The inspector general omitted a possible US strike on an Iranian school that remains under internal review. That omission is itself a data point. The first official ledger of the war still leaves some of the most contested incidents off the page.

The $33.4 billion figure stops on 30 June. Fighting, tanker losses and air-defence use have continued through July, August and mid-September. The next quarterly report will have to add those months. Until it does, the only official number the Pentagon has given Congress for the cost of the war is the one published on Monday, and it already includes a munitions shortfall the White House had publicly waved away.
