The US Department of Defense has awarded Raytheon a $258.7-million contract to develop and produce the Standard Missile-2 (SM-2) Block IIICU. The deal covers engineering, manufacturing, and development work, with completion expected by September 2031. The program includes $18.4 million in foreign military sales funding from Canada.
The Block IIICU marks a major upgrade over earlier SM-2 variants, improving its ability to counter diverse aerial threats such as tactical aircraft and anti-ship cruise missiles. The key advancement is a dual-mode seeker that integrates both semi-active and active guidance systems, replacing the older semi-active seeker. The missile will also share a modern guidance section and target-detection device with the SM-6 Block IAU, alongside enhancements such as a redesigned dorsal fin and thrust-vectoring assembly for better control.
With an estimated range of 90 miles (145 kilometers), the missile is slated for deployment across several US Navy platforms. These include Arleigh Burke-class and Zumwalt-class destroyers, Ticonderoga-class cruisers, and the upcoming Constellation-class frigates. Its integration with the Naval Integrated Fire Control – Counter Air network will allow coordinated tracking and engagement of threats across multiple ships and aircraft.
Production of the SM-2 had previously ended in 2017 but resumed in 2021 following renewed orders. The effort is heavily supported through foreign military sales, with allies such as Australia, Japan, South Korea, and Canada set to benefit alongside the US Navy. Interim capability for the Block IIICU was declared in 2022, with full-scale operational testing scheduled to begin in 2027 ahead of mass production.
