SM-3 Block IIA Co-Development

Abstract

The U.S. and Japan have a mutual interest in the evolutionary development of improvements to the SM-3. In FY 2006, the two countries signed a MOU for the co-development of an upgraded, 21-inch diameter SM-3 missile (SM-3 Blk IIA). The objective of the SCD project is the development and initial at-sea flight test of the SM-3 Blk IIA missile. The SM-3 Blk IIA missile will increase the area that can be defended by Aegis BMD and increase the probability of kill against a larger threat set. It will leverage enhanced capability provided by BMDS sensor upgrades. The SM-3 Blk IIA missile development will build upon established joint research investments by both the U.S. and Japan. The U.S. and Japan will equitable share both work and cost. Key technology improvements planned for the SM-3 Blk IIA missile include an increase in velocity and an increase in range provided by a 21-inch diameter rocket motor propulsion stack, and more than doubled seeker sensitivity and more than three times divert capability incorporated in an advanced kinetic warhead. Key component technologies to be developed under this Annex include, but are not limited to: Lightweight nosecone, advanced kinetic warhead, 21-inch second stage rocket motor, and 21-inch third stage rocket motor. The Scope of Work of the SCD project can be defined in three phases: Phase I takes the program through System Design Review (SDR) completion. Aegis BMD will execute risk reduction efforts for the propulsion, nosecone, seeker and Divert Attitude Control System (DACS) development efforts and test plans, and conduct requirements definition for the SM-3 Blk IIA missile configuration. Phase II will refine the scope of work from SDR through Critical Design Review (CDR) completion. Aegis BMD will refine requirements and define the performance allocation and component configuration for the development and testing of the SM-3 Blk IIA missile. Both parties will design, fabricate, test, and evaluate the SM-3 Block IIA missile sections per the agreed work-share. Phase III will refine the scope of work from CDR to the completion of the SCD flight test program as defined in the Agreement. This phase defines developmental cost share agreements between the United States and the Government of Japan, completes component engineering and integration, executes cooperative flight tests, and continues discussions on production and maintenance options. The SCD project will: -Develop components for the SM-3 Blk IIA missile and integrate them into an All Up Round (AUR): -21`` 2nd and 3rd stage components -21`` nosecone -Advanced kinetic warhead -Advanced Seeker -Large Diameter Divert and Attitude Control System -Integrate the SM-3 Blk IIA missile and VLS with Aegis ship systems: -Includes development of a light weight VLS canister -Conduct test and evaluation using ground- and flight testing using a modified Aegis BMD 4.0.1 system
