US Patriot missile stocks down 65% after Iran conflict; Pentagon seeks production boost

The U.S. military's stockpile of Patriot missiles has significantly diminished, falling by at least 65% compared to pre-conflict levels due to extensive use during the recent conflict with Iran. This depletion has prompted the Pentagon to take urgent action.

Deputy Secretary of Defense Steve Feinberg has issued a directive to the defense industry, demanding that contractors submit proposals within 21 days outlining how they can accelerate weapon deliveries or boost production. The current multi-year development cycles are deemed unacceptable in light of the urgent need to replenish critical munitions. The Strategic and International Studies Center (CSIS) estimates that the U.S. had approximately 2,330 Patriot interceptors before the war, which dropped to about 759-827 after recent combat operations.

The multi-year development cycle is no longer acceptable.

Similarly, interceptors for the Terminal High Altitude Area Defense (THAAD) system have also been depleted, though to a lesser extent. CSIS figures indicate a drop from about 452 interceptors pre-war to between 234-278 currently, a reduction of at least 38%. This reduction in THAAD interceptors is also a cause for concern.

The U.S. military and its Middle East allies may have to be more economical in the use of Patriot and THAAD interceptors, and may even reduce intercept launches when facing Iranian missile and drone attacks, in order to preserve limited inventories.

The declining inventory of these crucial interceptors could fundamentally alter U.S. air defense strategies. According to CSIS, the U.S. military and its allies in the Middle East may need to adopt a more conservative approach to employing Patriot and THAAD missiles. In the face of Iranian missile and drone attacks, they might even have to reduce the number of interceptor launches to conserve their limited stockpiles.

Pentagon spokesperson Sean Parnell confirmed the existence of Feinberg's memo and stated that measures to expedite weapon procurement and production will be integrated into the U.S. fiscal year 2028 defense budget. Meanwhile, President Trump recently downplayed concerns about U.S. ammunition shortages, asserting that the nation possesses "a lot" of weapons and that production and returns are ongoing.
