US Navy reveals plan for extended range SM-6 missile

25 March 2019

The US Navy (USN) has disclosed plans to fast-track the development and fielding of an extended range version of the Standard Missile-6 (SM-6) missile associated with the navy’s Aegis weapon system.

Known as SM-6 Block IB, the new variant is thought to be focused on improving the USN’s long range anti-surface warfare (ASuW) capabilities. Initial capability is forecast for fiscal year 2023 (FY 2023).

Developed and manufactured by Raytheon Missile Systems, the SM-6 missile is an evolutionary development that marries the propulsion, airframe, and warhead of the SM-2 Block IV missile with the active radar seeker of the AIM-120C-7 Advanced Medium-Range Air-to-Air Missile (AMRAAM) to provide an extended range anti-air warfare (AAW) capability over sea and land.
