SM-3 Block IIA Co-Development

Abstract

The U.S./Japan Joint Cooperative Research (JCR) program conducted cooperative research in Ballistic Missile Defense. The research focused on the development of advanced missile technologies in four components of the SM-3 guided missile: sensor, advanced kinetic warhead, second stage propulsion and lightweight nosecone. In FY 2006, the JCR project concluded with the flight testing of the lightweight nosecone in Joint Control Test Vehicle-1 (JCTV-1). In addition, 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 system analysis, system trade studies, and BMD system performance goals established in the U.S./Japan BMD Joint Analysis (JAWS) completed in March 2005 are the foundation for developing the SM-3 Blk IIA missile. Key technology improvements over the current SM-3 Blk IA missile planned for the SM-3 Blk IIA missile include a significant increase in velocity and range provided by a 21-inch diameter rocket motor propulsion stack, and increased seeker sensitivity and 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 U.S. and Japan will equitably share both work and cost. The Scope of Work of the SCD project can be defined in three phases: Phase I implements the SCD scope of work as it was defined in the original annex, taking the program through completion of the SDR. Aegis BMD will execute risk reduction efforts for the propulsion, nosecone, seeker and DACS development efforts and test plans, and conduct requirements definition for the SM-3 Blk IIA missile configuration. Phase I will also initiate information exchange related to production and maintenance of the SM-3 Blk IIA missile and introduce the phased engineering approach. Upon completion of requirements definition, a schedule for development and testing, and work share and cost share for development and testing will be refined. Phase II will capture program changes as set out in the first planned amendment, and refine the scope of work from SDR to completion of the CDR. 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, and both parties will design, fabricate, test, and evaluate the SM-3 Block IIA missile. Both parties will continue the information exchanges related to production and maintenance in Phase II. Phase III will capture program changes as set out in the second planned amendment, and 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 Improved Large Diameter Divert and Attitude Control System Begin engineering of the Aegis Weapon System to exploit the capability of the SM-3 Blk IIA missile and use of threat track data from BMDS sensors. 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 tests SM-3 Blk IIA missile Aegis BMD ship systems Aegis BMD weapon system
