SM-3 Block IIA Co-Development

Abstract

The objective of the SCD project is the development and initial at-sea flight test of the SM-3 Block IIA, and preparation for subsequent production decisions. The U.S. and Japan have a mutual interest in the evolutionary development of improvements to the SM-3. The SM-3 Block IIA 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. Technology improvements planned for the SM-3 Block IIA include an increase in velocity and range provided by a 21-inch diameter rocket motor propulsion stack, and more than doubled seeker sensitivity and more than tripled divert capability incorporated in an advanced kinetic warhead. Key component technologies to be developed include, but are not limited to: lightweight nosecone, advanced kinetic warhead, 21-inch second stage rocket motor, and 21-inch third stage rocket motor. Technology risk reduction will be conducted. The Scope of Work of the SCD project is defined in three phases: Phase I took the program through System Design Review (SDR) in FY 2009. Aegis BMD executed risk reduction efforts for the Propulsion, Nosecone, Seeker, Divert Attitude Control System (DACS) development efforts, and test plans. Phase 1 also included requirements definition for the SM-3 Block IIA Phase II encompassed the work from SDR through the Critical Design Review (CDR) in FY 2014. Aegis BMD refined requirements and defined the performance allocation and component configuration for the development of the SM-3 Block IIA. The U.S. and Japan designed, fabricated, tested, and evaluated the SM-3 Block IIA sections per the agreed work-share agreement. Phase III extends 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. Phase III is planned to complete in FY2017. The SCD project will: - Develop and integrate components for the SM-3 Block IIA into an All Up Round (AUR). Japan's work share includes 21 inch 2nd and 3rd stage components and the 21 inch nosecone. The U.S. workshare includes the advanced kinetic warhead, advanced seeker, large diameter divert and attitude control system, and lightweight VLS canister. - Integrate the SM-3 Block IIA Vertical Launch System (VLS) with Aegis ship systems.
