Aegis BMD

Abstract

Aegis BMD continues development of a sea-based BMD capability in project MD09, in support of the Missile Defense Agency`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 will primarily fall into two categories of BMD initiatives: Enhance Missile Defense to Defend Deployed Forces, Allies and Friends Against Theater Threats: -Aegis BMD 3.6.1 deployed now, element of the Phase Adaptive Approached (PAA) phase I, midcourse and terminal layer defense. -Aegis BMD 4.0.1 improved radar tracking accuracy and RF discrimination and increased raid capacity using Aegis BMD Signal Processor (BSP). -SM-3 Blk IB improved kinetic warhead. -Aegis BMD 5.0 integrates BMD capability into the Navy`s Aegis Modernization Program. -Aegis BMD 5.0.1 expands threat set and further increased the raid size, adds improved terminal defense capability. -Aegis BMD 5.1 implementation of SM-3 Blk IIA tactical capability. -Initial manufacturing of SM-3 Blk IB missiles. -BMD shipset installations aboard US Navy Cruisers and Destroyers. -Adaptation of Aegis BMD for use on land. Prove Missile Defense Works: -Aegis BMD element-level testing. -Participation in BMD System ground tests. -Element Modeling & Simulation. Aegis BMD 3.6.1 provides midcourse defense against SRBM, MRBM and IRBMs using the SM-3 Blk IA and terminal defense against SRBM with SM-2 Blk IV Missile. This configuration is deployed today supporting Combatant Commanders (COCOM) needs. It is key element of PAA phase I for defense of Europe and supports defense of friends and allies in the Pacific and other areas. Planned efforts include increasing the number the number of ships to 23 and continued integration with other element of the BMDS. Aegis BMD 4.0.1 SM-3 Blk IB will address more sophisticated and evolving threats. The ship receives a new signal processor that increases radar resolution to provide more accurate and discriminated track information and triples the possible number of simultaneous ballistic missile engagements over Aegis BMD 3.6.1 and revise existing launch on remote logic where SM-3 can be fired or flown based on off board sensor (e.g. AN/TPY-2, another Aegis BMD Ship, ABIR and STSS). The SM-3 receives a new kinetic warhead that includes a 2 color seeker, throttable engine and upgraded signal processor. Aegis BMD 4.0.1 does not include a terminal defense capability. Aegis BMD 4.0.1 will deliver in two spirals. Spiral two will continue through the System Engineering Development and Testing process and culminate as an operationally-certified system capable of BMD engagements using either the SM-3 Blk IA or IB missile. Other capability enhancements include functionality to support BMDS integrated Builds C and D: -Improvements in BMDS Command and C2BMC to ensure future BMDS sensor enhancements and the resulting discrimination capabilities are able to be communicated, correlated, and acted upon. Improved engagement coordination capability with THAAD and Patriot to conserve upper tier missiles, including Patriot upper tier debris mitigation. -Analysis for planned upgrades to the SM-3 missile to expand battlespace and improve discrimination, divert, and probability of mission success. -Supports BMDS Integrated Build C functionality: In Aegis BMD, this functionality includes deliberate and crisis Ballistic Missile Defense planning, Warfighter situational awareness, and the initial capability to control Regional BMD engagement between local assets and near-term improvements to threat discrimination. -Supports Integrated BMDS Build D functionality: In Aegis BMD, this functionality includes the Aegis BMD System (4.0.1 and Standard Missile (SM-3 Blk IB)) that provides significant improvements to both Radio Frequency (RF) and Infrared (IR) discrimination allowing for engagement of complex threats. Additional improvements to Aegis increase its ability to launch SM-3 interceptors on BMD System sensor data and improve Aegis coordination with the THAAD and Patriot weapon systems in the region. Approved additions to integrated Build D support initial Aegis BMD Ashore with control of engagement debris and refinements to BMD engagement coordination. Aegis BMD 5.0 will integrate Aegis BMD 4.0.1 capability into the Navy-developed OA computing environment. This change is necessary for Aegis BMD to remain compatible with Navy as Navy ship modernization plans are executed. This change will improve human-systems interface through display enhancements and eliminate the need for a separate computing system specific to the BMD mission. This will also enable more ships to serve as candidates for the BMD mission. Aegis BMD 5.0 will support the BMDS Integrated Build D and provide the basis for Aegis Ashore. Aegis BMD 5.0 will be enhanced by restoring the terminal defense layer, increasing raid capacity size and expanding the threat set to include those for PAA Phase II for defense of Europe and support of deployed forces, friends and allies and to increase this capability by delivering evolutionary improvements as part of Ballistic Missile Defense System (BMDS) upgrades. Aegis BMD 5.1 will integrate the SM-3 Blk IIA missile with an improved terminal defense capability and OA Aegis BMD Weapon System, incorporating other Weapon System improvements: -Defeat a wide variety of ballistic missiles in the presence of countermeasures: SRBMs, MRBMs, and IRBMs. -Increased battlespace with the SM-3 Blk IIA. -Engage on Remote (EoR) engagements allows use active and passive off board sensor information to launch and guide the SM-3 to final intercept. EoR engagements will use more of the SM-3`s kinematic envelope expanding battlespace, will increase the theoretical number of threats engaged over previous baselines both matching communications upgrades and make the overall architecture more resilient to adversary attempts to penetrate the BMDS. -Enhanced conventional discrimination. -Early Intercept (Organic). -Increased BMDS interoperability. -Enhanced Sea-Based Terminals. Aegis BMD 5.1 with the addition of the SM-3 Blk IIB expands the threat set to include some Inter-continental Ballistic Missiles (ICBMs) . Aegis BMD supports an autonomous engagement against SRBMs and MRBMs without requiring external cueing. It supports an engagement against SRBMs and MRBMs 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 LRBMs.
