U.S. Air‑Defense Stockpiles Shrink Amid Iran War

U.S. air‑defence Patriot interceptors THAAD Iran war stockpile depletion

U.S. defense analysts say the war with Iran has rapidly depleted the United States' air‑defence inventories. The Center for Strategic and International Studies (CSIS) estimates fewer than 827 Patriot interceptors and fewer than 278 THAAD interceptors remain, down roughly 65 % in Patriots since the conflict began in late February. In April the Pentagon fired almost half of its Patriot missiles and at least half of its THAAD interceptors, and production of a new Patriot interceptor now takes over two years.

Defense Secretary Pete Hegseth has asked Congress for an additional $87 billion to address the shortfalls, while President Donald Trump has publicly insisted the stockpiles are “in very good shape.” Analysts warn the shortages could limit U.S. response options in a potential Taiwan‑China confrontation and increase risk for U.S. and allied forces worldwide.
