RTX Raytheon Supplies Certified Parts for SM-3 Missile-Defense Interceptor
February 24, 2025 – The RIM-161 Standard Missile-3 (SM-3) Block 1B, utilized by the U.S. Navy, is designed to intercept and neutralize ballistic missiles traveling short to intermediate ranges. Under a newly announced contract valued at $99 million, RTX Corp. will supply essential components that enhance the missile’s ability to detect and eliminate incoming threats.
Based in Tucson, Arizona, RTX Raytheon will adhere to strict specifications set forth by the U.S. Missile Defense Agency (MDA) in Huntsville, Alabama, for the manufacturing, assembly, and testing of the SM-3 Block IB parts.
Ballistic Missile Defense Overview
The Standard Missile-3 serves as a hit-to-kill solution for ballistic missile defense, utilizing an exoatmospheric kill vehicle to collide with targets during their mid-course phase. This approach ensures that no explosives are necessary; the impact itself delivers extreme force equivalent to that of a 10-ton truck traveling at 600 mph, thereby obliterating its target.
These missiles can be launched from land installations or from Navy Aegis-equipped vessels. The Block IB version features an upgraded two-color infrared seeker and enhanced steering capabilities that strategically guide the missile to incoming threats through precision bursts of propulsion.
Progress and Development of SM-3 Variants
The SM-3 Block IB became operational in 2014 and marked its inaugural deployment aboard U.S. Navy ships. Meanwhile, the next iteration, the SM-3 Block IIA, is being developed in collaboration with Japan to improve defense capabilities on both land and at sea. This variant features larger rocket motors and a more potent kinetic warhead, enabling it to cover more extensive areas against ballistic missile attacks.
RTX Raytheon is expected to complete the current contract work by March 2026. For further inquiries, visit RTX Raytheon or contact the Missile Defense Agency at www.mda.mil.
