U.S. munitions: prewar inventory vs. what's left

Estimated inventory of seven critical munitions before and after the first 39 days of the 2026 Iran war (Feb 28–Apr 8 ceasefire)

Tomahawk and JASSM figures reflect an open-ended usage estimate ("1,000+" and "1,100+" expended); their "remaining" bars are ceilings, not precise estimates — actual stock could be lower. Remaining figures for PrSM, SM-3, SM-6, THAAD, and Patriot are midpoints of CSIS's reported ranges — hover for full range. THAAD's prewar figure (360) was later revised upward to 452 in CSIS's July 27 update; this chart uses the original April figure for consistency with the rest of the table.
