Iran War Deepens Global Missile-Defense Shortage for Years
A CSIS analysis warns the Iran war is draining U.S. missile interceptors faster than they can be replaced, likely leaving stockpiles unreplenished until 2029 and stressing allies from Ukraine to Taiwan. The U.S. used more than 1,000 interceptors in the Iran conflict in fiscal 2026, while delivering just 172 Patriot interceptors; to close the gap, the Pentagon has pushed production increases with Lockheed Martin (THAAD), Boeing (PAC-3 seekers), and RTX (SM-6), and is weighing cheaper options as stockpile shortages linger. Decision-making over what to shoot down and with which munition remains costly and high-stakes for U.S. defenses and partners.
