“US Navy warships have twice been called upon to defend Israel from massive Iranian ballistic missile attacks and have used SM-3 interceptors to defeat the incoming threats.
The Standard Missile-3 (SM-3), a key air-defense interceptor made by RTX and, for some variants, Mitsubishi Heavy Industries, was first used in combat in April to shield Israel from an unprecedented attack, and then it saw combat again in October when Iran attacked a second time. The weapons, which can cost between $10 million and almost $30 million depending on the variant, were fired by American destroyers in the area.
Navy leadership has said that it needs many more SM-3s to counter threats in the Pacific, like China, but it’s burning through these weapons in conflicts in the Middle East without sufficient plans to replace them.
Archer Macy, a retired Navy admiral, told Business Insider that the SM-3 is particularly important in a fight with China because the interceptor is designed to counter China’s “apparent preference for long-range theater weapons.””
