The Pentagon is weighing whether it can sustain its current retaliatory strike cycle against Iran as US Patriot and THAAD interceptor stockpiles have plunged to their lowest levels since the war began.
Pentagon Confronts Shrinking Missile Stockpile After Months of Iran Fighting
America’s air defenses are running thin. The Center for Strategic and International Studies estimates US Patriot interceptor inventories have fallen from roughly 2,300 pre-war to fewer than 827, while THAAD stockpiles dropped from 452 to under 278.
Analysts say Iran’s strategy of targeting US bases is deliberately forcing the depletion of these advanced interceptors, pushing the Pentagon to accept greater risk in defending troops as the conflict drags on. CSIS warned Iran appears to be betting this approach gives it the best chance of outlasting the US military, with rebuilding the stockpile potentially taking three years or more.
