Aegis BMD

Abstract

Aegis Ballistic Missile Defense (BMD) continues development of a sea-based BMD capability, in support of the MDA's mission to protect the homeland, deployed forces, friends and allies from ballistic missile threats of all ranges and in all stages of flight. Aegis BMD efforts primarily enhance Missile Defense to defend deployed forces, allies and friends against theater threats: - Aegis BMD 5.0 Capability Upgrade (CU) expands the threat set and increases the raid size - Aegis BMD 4.1 backfits the Aegis 5.0 CU(endo-atmospheric(ENDO) and exo-atmospheric(EXO) into the BMD 4.0 architecture - Aegis BMD 5.1 expands the threat set through the introduction of Engage on Remote(EoR) and the integration of the Standard Missile-3(SM-3) Block IIA - Aegis BMD 4.x/5.3.x merges Aegis BMD 4.1 (including BMD 5.0 CU capability) and U.S. Navy Baseline 5.3 into a single computer program for the BMD 4.0 architecture. - Aegis BMD 6.x will apply the Advanced Capabilities Baseline(ACB)-20 BMD capability to Guided Missile Destroyer (DDG) Flight III in alignment with the Navy: provides increased organic engagement, search & track and Integrated Air and Missile Defense (IAMD) capability based on SPY-6, also known as the Air & Missile Defense Radar (AMDR) Aegis BMD 5.0 Capability Upgrade (CU) will enhance Aegis BMD 5.0 by improving the ENDO and EXO capability, increasing the maximum number of SM-3's in flight simultaneously, expanding the threat set to include those for EPAA Phase II, and increasing this capability by delivering improvements as part of the Ballistic Missile Defense System (BMDS) upgrades. Aegis BMD 4.1 builds upon Aegis BMD 4.0 and adds Aegis BMD 5.0 CU capabilities providing European Phased Adaptive Approach (EPAA) Phase II EXO threat capability increase, SM-3 Maximum number Missiles In Flight (MAX MIF) improvements, multi-mission (Anti-Air Warfare (AAW) and BMD) warfare integration, , Mark (MK)-41 Vertical Launching System (VLS) and Mission Planner capabilities. Aegis BMD 5.1 builds upon BMD 5.0 CU and will further expand the threat set which is required for EPAA Phase III. This includes the introduction of an EoR capability and the integration of the SM-3 Block IIA. An EoR engagement allows the use of active and passive off board sensor information to launch and guide the SM-3 Block IIA to final intercept. The increased kinematic envelope of the SM-3 Block IIA when combined with EoR will expand the battlespace and increase the number of threats engaged over previous baselines. Aegis BMD 4.x/5.3.x merges Aegis BMD 4.1 and USN Baseline 5.3 into a single integrated computer program. BMD 5.3.x increases BMD threat capability and exploits track and detection improvements of the SPY-1 Low Noise Amplifier (LNA) Refurbishment. - Legacy Aegis BMD Cruisers and Destroyers possess two separate, certified computer programs: BMD 4.1 for Ballistic Missile Defense missions and Aegis Baseline 5.3 for Anti-Air Warfare (AAW), Surface Warfare (SUW), and Undersea Warfare (USW). This integration remedies the current need for the warfighter to switch between Baseline 5.3 and BMD 4.0 based on the warfighting mission requirement. Benefits of the single computer program are: - Enables warfighter to switch between BMD missions or AAW/SUW/USW missions - Integrates Air and Missile Defense into a single computer program on legacy computer program architecture - Enables future capability enhancements and threats with Aegis BMD 4.x - Enables future SPY-1 Low Noise Amplifier (LNA) Refurbishment efforts to maintain ship relevance through End of Service Life Aegis BMD 6.x provides an increased BMD capability by incorporating the Air and Missile Defense Radar (AMDR), now designated for SPY-6 for the introduction on the first DDG Flight III. The objective is to achieve tracking and discrimination improvements to counter evolving threats and raids in support of homeland/regional defense. BMD 6.x will enable BMDS element utilization of AMDR data for remote engagement and supplement deployed assets with simultaneous multi-mission capabilities (e.g. IAMD). It will include updates for advanced planning; search, track, and discrimination; and kill assessment. SPY-6 will support force-level (multi-asset) approach to raid defense and enable Navy ships greater stand-off range from threat environments. The SM-3 Block IB improves Aegis BMD's ability to engage longer range, more sophisticated ballistic missiles that may deploy countermeasures and launch in larger raid sizes. The SM-3 Block IB Kinetic Warhead`s (KW) two-color infra-red (IR) seeker and advanced signal processor provides a real-time discrimination and characterization capability while improving sensitivity for longer range targets and performance against more sophisticated threats. Additionally, the new Throttleable Divert and Attitude Control System (TDACS) KW divert engine has been upgraded over the SM-3 Block IA to provide a more flexible divert in order to maneuver the KW to intercept. The SM-3 Block IIA is a cooperative project developed by Aegis BMD and the Japan Ministry of Defense. The SM-3 Block IIA consists of a spiral upgrade to a 21-inch diameter SM-3 missile and will expand available battlespace to include Intermediate Range Ballistic Missile (IRBM) and selected longer-range threats. When combined with Aegis BMD 5.1 weapon system modifications the SM-3 Block IIA will provide EoR capability. The discrimination improvements effort will develop and field integrated Element capabilities to improve BMD System ability to identify lethal and non-lethal objects. AEGIS BMD will continue targeted discrimination improvements, enterprise improvements to detect, track, discriminate and correlation, and threat data and modeling updates.
