US Military Depletes Majority of Missile‑Defense Stockpiles in Iran War
U.S. forces have used roughly 80 % of their THAAD interceptors and about half of their Patriot missiles since the conflict with Iran began, according to multiple sources and a CSIS inventory review. The same reports say the Army has expended virtually all of its Army Tactical Missile Systems (ATACMS) and Precision Strike Missiles (PrSM), and that roughly half of the Tomahawk cruise‑missile stockpile has been fired.
Before the war the United States held about 452 THAAD interceptors and 2,200 Patriot missiles; by late July those numbers had fallen to an estimated 234‑278 THAAD and 759‑827 Patriot missiles. Pentagon and White House officials have repeatedly denied a shortage, asserting that the military “has everything it needs.” Gulf‑region allies, which rely on U.S. air‑defence systems, have expressed concern that the depletion could limit their ability to counter Iranian missiles and drones.
The Pentagon says it is accelerating production of interceptor components, but analysts estimate that full replenishment could take years, with some estimates extending to 2029. The debate over munitions levels resurfaced just before President Donald Trump cancelled a planned strike on Iran, citing senior advisers’ warnings about the dwindling stockpiles.
