AB Capability 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 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 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 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 BMD 5.1 will integrate the SM-3 Blk IIA missile with the Aegis BMD Weapon System in Open Architecture, incorporating other Weapon System improvements: Defeat a wide variety of ballistic missiles in the presence of countermeasures SRBMs, MRBMs, IRBMs, LRBMs, including limited ICBMs. Feature Aided Track Correlation (FATC) Forcenet/GIG Compliance Improvements to BMDS Multi-Element Sensor Data Fusion. Engage on Remote (EoR) Aegis Ashore: The Phased Adaptive Approach (PAA) was developed in response to the rapid proliferation of short and medium range ballistic missiles in Iran and the threat they pose to U.S. allies and partners, as well as to U.S. deployed personnel and their accompanying families in the Middle East and Europe. By leveraging recent advances in sensor and interceptor technologies, the United States will aggressively counter this growing regional threat with a more powerful and agile system. The United States is pursuing a four-phased approach which will provide a more effective missile defernse capability for defense of NATO territories and enhance U.S. homeland defense; it will be complementary to and interoperable with those being developed by NATO, be applicable in other theaters around the world, and will be more adaptable and flexible to counter threat advances and provide increased defended areas over time. The initial phase includes the deployment of current and proven missile defense technologies, including the sea-based Aegis Weapons System, the SM-3 missile (Block IA and IB), and sensors such as the AN/TPY-2. Subsequent phases will be implemented based on technical maturity, appropriate testing, and threat driven requirements. Aegis Ashore will reinforce and support the existing Host Nation`s upper-tier system and defend deployed forces, allies, and friends against theater threats. Furthermore, Aegis Ashore will allow for more sophisticated engagement strategies and reduce vulnerability to countermeasures, forcing an enemy to alter or abandon tactics to penetrate the defensive system. MDA plans to complete a concept study effort to flesh out the system`s technical and operational feasibility leading to a near-term demonstration. To support this effort, MDA tasked Aegis BMD to oversee the execution of this study and analysis. MDA anticipates an Aegis Ashore acquisition strategy to be approved during FY 2010 In collaboration with the MDA systems engineer, Aegis BMD 5.1 will support an autonomous engagement against SRBMs, MRBMs, IRBMs, LRBMs and some ICBMs without requiring external cueing. It will also support an engagement against SRBMs, MRBMs, IRBMs and LRBMs using data from other BMDS elements and external sensors. Aegis BMD will also provide target track data to support Ground Based Interceptor Launch and Engagement against IRBMs and ICBMs via input for GMD.
