- U.S. Patriot interceptor stocks fell from 2,330 to under 850 after roughly 65% were expended between February and July, according to CSIS estimates, with inventories further drained by the Iran war.
- Saudi Arabia consumed about 86% of its 2,800 PAC-3 interceptors in the first 38 days of combat, leaving just 400 missiles remaining as of April, CSIS said.
- The U.S. Army awarded Lockheed Martin a contract worth up to $58.6 billion in July to produce additional Patriot interceptor missiles, described as the largest-ever PAC-3 deal.
- The U.S. State Department approved sales of 5,250 interceptors to Bahrain, Kuwait, Qatar, and the UAE to replenish Gulf stockpiles, while 6 to 8 countries have requested additional missiles.
- Lockheed Martin introduced a new PAC-3 Adapted Capability Effector (ACE) interceptor in July that costs roughly half as much as existing models while retaining the ability to target short-range ballistic missiles, aircraft, and cruise missiles.
- Ukraine is urgently pressing for more interceptors to counter nightly Russian ballistic missile barrages, and the U.S. is advancing talks to allow Ukraine to manufacture Patriot components domestically despite President Trump's stated doubts.
- A single Patriot battery costs over $1 billion — roughly $400 million for the system and $690 million for its missiles — with individual PAC-3 interceptors priced at $4 million to $5 million apiece.
Why it matters: With the U.S. down to its last 850 interceptors and Gulf allies nearly tapped out, Washington faces a hard tradeoff between resupplying frontline partners and maintaining its own homeland defense shield — a gap the new $58.6 billion Lockheed contract and proposed Ukrainian production are explicitly meant to close.
