- US Patriot stockpile fell from approximately 2,330 missiles before the Iran war to about 800 now, with Col. Robert Hamilton stating the US has expended "almost two-thirds" of its supply and has even diverted interceptors European allies had already purchased.
- Patriot production currently runs about 600 missiles per year; a $58 billion contract aims to scale that to 2,000 annually, but the first missiles won't arrive until early 2029 and full fulfillment isn't expected until 2032.
- Gulf allies are reportedly firing four to eight Patriot interceptors at each incoming Iranian ballistic missile, compared with Ukraine's near one-to-one shootdown rate — a discipline developed over 4.5 years on roughly 600 missiles received total.
- France announced it will deliver two SAMP/T batteries — a French-Italian Patriot-like system — to Ukraine this year, and a joint US-Ukrainian effort to retrofit S-300 missiles is expected to come online by late 2026 at roughly 100-200 units per year.
- The US Army has reportedly expended essentially its entire ATACMS stockpile and nearly half of the next-generation PrSM missiles, according to Hamilton, who called the Gulf war's weapons consumption a "theater tax" on other potential conflict zones like Europe and the Indo-Pacific.
- European allies have even fewer remaining Patriots than the US because they donated heavily to Ukraine in the early years of the war, and the Patriot remains the only system produced in large numbers capable of reliably intercepting Russian ballistic missiles at high rates.
Why it matters: The US has burned through roughly two-thirds of its Patriot stockpile fighting Iran, leaving Ukraine — facing daily Russian ballistic missile strikes — competing with the Middle East and Indo-Pacific for interceptors that won't be produced at scale until 2029. Hamilton warned the expenditure rate now puts America at risk in any multi-theater conflict scenario, as ATACMS and PrSM stockpiles face similar depletion.
