Overview
- The CSIS analysis, published Tuesday, says seven weeks of strikes and air defense in the Iran war consumed large shares of high-end U.S. munitions.
- Researchers estimate at least 45% of Precision Strike Missiles are gone, roughly half of THAAD and Patriot interceptors are spent, and about 30% of Tomahawks and over 20% of JASSMs and SM-3/SM-6 are used.
- Pentagon spokesman Sean Parnell says the military can meet current taskings and sustain operations against Iran if the fragile ceasefire collapses.
- Contracts to ramp production are in place, yet experts say refilling inventories will take three to five years because complex missiles have long build times and industry has limited near-term output.
- Analysts warn the drawdown opens a window of vulnerability in the western Pacific, where a clash with China would require far deeper magazines and could force trade-offs that slow deliveries to partners.
