The US military is running out of Patriot missile interceptors in Europe, according to defense and NATO officials, and the shortage is the most acute since the system was fielded. The most concerning shortfall is in the interceptors themselves — the expensive, finite warheads that shoot down ballistic and cruise missiles — not the launcher batteries, which remain in place.
The implication, as one official put it, is that in the event of a sustained Russian ballistic missile attack on allied territory, US and NATO forces would be unable to intercept every incoming round. The fallback is the same one Ukraine has relied on since 2022: ‘take punch after punch’ and hope the attack subsides. That is not a defense strategy. It is a damage-limitation posture.
The Iran war has consumed much of the interceptor stockpile. Every engagement over the Strait of Hormuz, every defensive shot against Iranian missile and drone salvos, has drawn down a finite supply that was already stretched thin by the Ukrainian theater. A new US aircraft carrier is reportedly set to deploy to the Middle East, but carriers do not manufacture interceptors.
The strategic calculus for Israel is direct. The region now has a credible scenario in which the US air defense umbrella — the one Israel has been counting on for high-value ballistic threats — has a hole in it. The Patriot gap is not a theoretical exercise. It is the result of active combat in two theaters simultaneously, and it will take months to close.
NATO’s answer, for now, is to accelerate procurement and hope the conflict timeline works in their favor. That is a bet, not a plan.
