SM-3 Block IIB-Technology Risk Reduction

The SM-3 Block IIB program objective is to develop an operational, hit-to-kill missile defense interceptor that provides early intercept capability against both intermediate-range and intercontinental ballistic missile threats. The Block IIB missile consists of three stages and a Kill Weapon (KW).

The program is the fourth phase of the government’s Phased Adaptive Approach (PAA) to defend Europe and the U.S. Homeland.  Its planned Initial Operational Capability is in the 2021 timeframe.

SM-3 Block IIB must be both land and sea compatible and be integrated into the current Aegis Weapon System, using the Mk-41 vertical launch system as a point of departure.

MDA is currently conducting source selection Technology Risk Reduction (TRR) efforts for the Third Stage Rocket Motor (TSRM) and the Solid Divert and Attitude Control System (SDACS).

The Rocket Shop conducts the R&D and technology demonstration for several SM-3 propulsion systems in preparation for future contracts.
