Think tank warns that weapons shortfalls could leave American forces vulnerable in a future conflict – and Chinese observers agree
2-MIN READ2-MINLiu ZhenPublished: 6:00pm, 23 Apr 2026The United States’ depleted stockpile of munitions from its war on Iran and limited production capacity will be a critical vulnerability against stronger adversaries, according to Chinese military observers.During the 39 days of war before the ceasefire, the US is estimated to have used about half of both its Patriot air defence missiles and the longer-range Terminal High Altitude Area Defence (THAAD) interceptors.Stockpiles of Standard Missile 3 (SM-3) and Standard Missile 6 (SM-6) ship-launched interceptors have also dropped significantly, according to a report published by the Centre for Strategic and International Studies (CSIS) on Tuesday.
Meanwhile, the US military has expended between 40 and 70 of its 90 Precision Strike Missiles (PrSM), the most advanced munition developed for the Himars multiple rocket launchers.
The think tank report also revealed that more than a quarter of the 3,100 Tomahawk cruise missiles and nearly a quarter of the 4,400 stealth Joint Air-to-Surface Standoff Missiles (JASSM) were fired.
