As part of its effort to develop a global ballistic missile defense (BMD) system, the Department of Defense (DOD) is modifying 18 Navy cruisers and destroyers for BMD operations, and has deployed a large BMD radar -- the Sea-Based X-Band Radar (SBX) -- on a modified floating oil platform. The eventual role of sea-based systems in the worldwide U.S. BMD architecture has not been determined. The overall issue for Congress discussed in this report is: What should be the role of seabased systems in U.S. ballistic missile defense, and are DOD's programs for seabased BMD capabilities appropriately structured and funded? The Aegis BMD system in its current configuration is intended to track ballistic missiles of all ranges, including intercontinental ballistic missiles (ICBMs), and to intercept shorter-ranged ballistic missiles. The current configuration is not intended to intercept ICBMs. Current DOD plans call for modifying 3 Aegis cruisers and 15 Aegis destroyers with the Aegis BMD capability by the end of 2008. Future versions of the Aegis BMD system are to include a faster interceptor designed to intercept certain ICBMs. The Aegis BMD system has achieved 13 successful exo-atmospheric intercepts in 15 attempts. The system was also temporarily modified and used on February 20, 2008, to shoot down an inoperative U.S. surveillance satellite. Japan is acquiring the Aegis BMD system, and some other allied navies have expressed an interest in adding BMD capabilities to their ships. For FY2009, the Missile Defense Agency (MDA) is requesting $1,157.8 million in research and development funds for the Aegis BMD program. The program also receives some additional Navy funds. Potential specific issues for Congress regarding sea-based BMD systems include technical risk in the Aegis BMD program, the number of Aegis BMD ships, the role of Aegis BMD in European missile defense, the number of SM-3 interceptors planned for procurement, the proposal to equip the SM-3 Block IIA missile with a Multiple Kill Vehicle (MKV), whether development a far-term sea-based terminaldefense BMD capability should be accelerated, the potential role of the Kinetic Energy Interceptor (KEI) in sea-based BMD operations, procurement of the planned CG(X) cruiser, development and testing of the Aegis BMD system, and potential allied sea-based BMD programs. This report will be updated as events warrant. [ABSTRACT FROM AUTHOR]
