WASHINGTON (AP) — Recent fighting with Iran used up more of the U.S. military’s already diminished stockpiles of advanced missile interceptors, potentially putting American troops at more risk if hostilities resume, a new analysis says. For example, it said, American forces may launch fewer missiles against incoming Iranian drones and missiles, raising the chance of one getting through. CSIS warned in May that it could take at least three years to replenish stockpiles of Patriots, THAADs and Tomahawk cruise missiles. The number of Patriot interceptors fell from 2,330 before the war to 1,030 when the April ceasefire took effect, CSIS estimated. But as an example, Cancian said American forces could start firing off two interceptors instead of three.
