Iran war exposed US munitions shortfalls and production bottlenecks, Pentagon IG says

Coverage of the DoD Inspector General's first Iran war report (Feb 28 - Jun 30): $22.3B of the war's $33.4B cost was expended munitions, and officials described shortfalls plus industrial bottlenecks. No per-missile counts.

Hegseth disputes reports of depleted US missile interceptor stocks

Relays CNN's report, based on a recent inventory assessment, that nearly 80% of THAAD and about half of Patriot interceptors have been used. Hegseth called it "NOT TRUE." CNN's percentages sit on an undisclosed baseline, so they aren't used in the headline numbers.

U.S. has used nearly all its stockpile of long-range missiles in Iran war, sources say

Two sources tell CBS the Army has used virtually all of its ATACMS and PrSM missiles; Reuters reported it first. Officials call Patriot and THAAD the most pressing concern.

Six Reasons Why the United States Is Low on Munitions

CSIS says about half the initial inventory of Patriot, THAAD and PrSM has been used, and about a third of JASSM, Standard Missiles and Tomahawk. It argues enough remains for Iran, and the risk is a future war with China.

How this works

Estimates, labeled

Stockpiles are classified. Every number carries a tag: Official on the record from a government body, Reported journalists citing officials or documents, and Estimate an analyst's model built from budget documents.

Quotes, checked

Each claim stores the exact sentence it came from. Before anything is published, a script fetches the source and confirms the quote is really there.

A model you can push on

Each missile page projects the stockpile forward from the budget's delivery schedules, and lets you change production rates or start a renewed war.
