Pentagon Pushes Defense Contractors to Speed Weapon Production as Iran War Drains Stockpiles

The conflict with Iran has exhausted large portions of the United States’ Patriot and Terminal High Altitude Area Defense (THAAD) interceptor stocks. Prior to the war, the U.S. possessed 2,330 Patriot interceptors and 452 THAAD interceptors. By the April cease-fire, Patriot numbers fell to 1,030 and THAAD to 232-262, according to the Center for Strategic and International Studies (CSIS). A later CSIS estimate dated July 27 placed the remaining Patriot inventory between 759 and 827 and THAAD between 234 and 278, representing reductions of at least 65 % and 38 % respectively.
