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 5.0 Capability Upgrade (CU) will enhance legacy Aegis BMD 5.0 by improving endo- and exo-atmospheric capabilities, increasing the maximum number of SM-3s in flight simultaneously, expanding the threat set to include those for European Phased Adaptive Approach (EPAA) Phase II, and increasing this capability by delivering improvements as part of Ballistic Missile Defense System (BMDS) upgrades. Aegis BMD 4.1 capability builds upon legacy Aegis BMD 4.0 and captured all the threats built into Aegis BMD 5.0 CU. It includes Discrimination Improvements algorithms, and an increased BMD threat set, and provides increased maximum engagements and maximum missiles-in-flight over BMD 4.0. Aegis BMD 5.1 builds upon Aegis BMD 5.0 CU (COTS based open architecture) and further expands the threat set to include threats which are required for EPAA Phase III. This includes the integration of the SM-3 Block IIA, introduction of an Engage on Remote (EoR) capability, and improved BMDS interoperability and engagement coordination. Aegis BL 5.4 (BMD 4.1) merges the BMD 4.1 capability with the United States Navy (USN) Aegis Baseline 5.3 into a single integrated computer program with planned Navy Certification in FY 2019. Twenty-one legacy Aegis Flight I/II Destroyers, not planned for Aegis Modernization (AMOD), possess two separate certified computer programs: Aegis BMD 4.0 for Ballistic Missile Defense missions and Aegis Baseline 5.3 for Anti-Air Warfare (AAW), Surface Warfare (SUW), and Undersea Warfare (USW). The Aegis BL 5.4 (BMD 4.1) computer program integrates Aegis Baseline 5.3 and Aegis BMD 4.0 to remedy the need for the warfighter to use both simultaneously. An additional benefit of the single integrated computer program is enabling future SPY-1 Low Noise Amplifier (LNA) Refurbishment efforts to be added during the ship's Service Life Following Aegis BL 5.4, the Aegis BL 5.4.X (BMD 4.2) AN/SPY-1 upgrade with the US Navy will provide refurbishment of existing ship AN/SPY-1 radar arrays with the installation of antenna Low Noise Amplifiers (LNAs)(MDA funding beginning in FY19). These refurbished and upgraded antennas, when integrated with Aegis BL 5.4.X (BMD 4.2), will increase BMD capabilities with improved sensitivity, discrimination, and more efficient radar resource utilization. Aegis BMD 6.x provides an increased BMD capability by incorporating the Air and Missile Defense Radar (AMDR), now designated SPY-6 for introduction on the first DDG Flight III. Aegis BMD 6.0 will enable BMDS element utilization of AMDR data for remote engagement and supplement deployed assets with simultaneous multi-mission capabilities (e.g. Integrated Air and Missile Defense (IAMD)). It will include IAMD planning; search, track, and discrimination. Aegis BMD 6.1 will continue to provide an increased BMD capability with the SPY-6 radar. It will include updates for advanced threats, advanced planning, search, track, and discrimination improvements; and kill assessment updates. SPY-6 will support force-level (multi-asset) approach to raid defense and enable Navy ships greater stand-off range from threat environments.
