The US has warned allies that deliveries of key weapons could be delayed by up to five years as Washington replenishes munitions depleted during its seven-month conflict with Iran. The shortages affect Patriot air-defense interceptors, Tomahawk cruise missiles, Typhon launchers, THAAD interceptors and other systems. Germany has asked Washington to accelerate deliveries of Tomahawks and Typhon launchers, but Raytheon, an RTX unit, may be unable to complete the order within five years. Ukraine is also seeking additional Patriot interceptors before an expected difficult winter. President Donald Trump has said the US is considering supplying Ukraine with a less advanced Patriot variant or allowing European countries to manufacture the weapons under license. The US is estimated to have used more than half of its advanced Patriot variants, about one-third of its Tomahawks and nearly half of its precision strike missiles and THAAD interceptors during the Iran conflict. Pentagon officials have acknowledged strategic inventory shortfalls and production bottlenecks. Lockheed Martin plans to increase annual PAC-3 MSE Patriot interceptor production from about 600 to 2,000. The new warning adds to earlier reports that NATO members including the UK and Poland, Japan and other allies face delivery delays while exploring alternative suppliers. European leaders are expected to press Trump for more Patriot support for Ukraine at meetings in New York, while EU officials seek US licenses for European production.
