SM-3 Block IIA Co-Development

Abstract

The U.S. and Japan have a mutual interest in the evolutionary development of improvements to the Standard Missile-3 (SM-3). The objective of the SCD project is the development and initial at-sea flight test of the SM-3 Block IIA missile, and preparation for subsequent production decisions. The SM-3 Block IIA missile will increase the area that can be defended by Aegis Ballistic Missile Defense (BMD) and increase the probability of kill against a larger threat set. It will leverage enhanced capability provided by Ballistic Missile Defense System (BMDS) sensor upgrades. Key technology improvements planned for the SM-3 Block IIA missile include an increase in velocity and an increase in range provided by a 21-inch diameter rocket motor propulsion stack, more than doubled seeker sensitivity and more than three times 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 to reduce key component development risk. The Scope of Work of the SCD project is defined in three phases: Phase I took the program through System Design Review (SDR) completion. Aegis BMD executed risk reduction efforts for the Propulsion, Nosecone, Seeker, Divert Attitude Control System (DACS) development efforts, and test plans. Conducted requirements definition for the SM-3 Block IIA missile configuration. Phase I was completed in FY 2009. Phase II refined the scope of work from System Design Review (SDR) through Critical Design Review (CDR) completion. Aegis BMD refined requirements and defined the performance allocation and component configuration for the development and testing of the SM-3 Block IIA missile. Both the U.S. and Japan designed, fabricated, tested, and evaluated the SM-3 Block IIA missile sections per the agreed work-share agreement. Phase II was completed in FY 2014. Currently, phase III refines 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 Block IIA missile and integrate them into an All Up Round (AUR): e.g., 21 inch 2nd and 3rd stage components (Japan work share); 21 inch nosecone (Japan work share); Advanced kinetic warhead (United States work share); Advanced seeker (United States work share); Large diameter divert and attitude control system (United States work share); Integrate the SM-3 Block IIA missile and Vertical Launch System (VLS) with Aegis ship systems - Include development of a light weight VLS canister (United States work share) - Conduct test and evaluation through ground and flight testing using the Aegis Ballistic Missile Defense (BMD) 5.1 system (Joint work share)
