The Standard Missile-3 (SM-3) is a ship-based missile designed to intercept and destroy short- to intermediate-range ballistic missiles in their midcourse phase. Developed by Raytheon and Mitsubishi Heavy Industries, it is part of the United States' Aegis Ballistic Missile Defense System, which uses advanced radar and tracking technology to identify and engage threats. The SM-3 features a kinetic warhead that collides with incoming missiles to neutralize them, rather than using explosives. It has undergone several upgrades since its introduction, improving its range and effectiveness against evolving missile threats, thereby enhancing global security and defense capabilities.
