U.S. burning through ‘years’ of munitions in Iran war – FT | 13 March 2026 | The U.S. is rapidly depleting its weapons stockpiles and has “burned through years” of some critical munitions since starting its war against Iran, the Financial Times reported on Friday, citing people familiar with the matter. In a closed‑door briefing on Tuesday, Pentagon officials estimated that the first six days of the U.S. war with Iran have already cost at least $11.3 billion, according to the outlet. The rapid munitions drain has stoked fears over the soaring cost of the war and Washington’s capacity to restock key weapons, including advanced long-range Tomahawk missiles, the FT said. The Washington-based Center for Strategic and International Studies estimated that U.S. forces fired 168 Tomahawk cruise missile during the first 100 hours of the operation against Iran.
