Lower Tier Air Missile Defense (LTAMD) Capability

Abstract

This funding line is directly aligned to the Army Air and Missile Defense Modernization Priority. The Lower Tier Air Missile Defense Sensor (LTAMDS) is a next generation sensor intended to sense and track Tactical Ballistic Missiles and Air Breathing Threats; expand the battlespace for Missile Segment Enhancement interceptor; and provide 360-degree sensing capability, surveillance, and fire control in the Lower Tier Army Integrated Air and Missile Defense (IAMD) ballistic missile defense battlespace. The LTAMDS program competitively selected Raytheon as the prime vendor in 1st Quarter (Q) Fiscal Year (FY) 2020 to build six (6) Prototype sensors under the Section 804 Rapid Prototyping authority. The sensor/Radar Set (RS) replaces the baseline PATRIOT RS (AN/MPQ-65A) in an Integrated Air and Missile Defense Battle Command System (IBCS) enabled PATRIOT Battalion mitigating risk associated with threat advances, decreasing Operations and Support (O&S) costs, and growing obsolescence. Additionally, the LTAMDS capability increases sensor/ radar performance to maximize the inherent PATRIOT Advanced Capability (PAC-3) Missile Segment Enhanced (MSE) Interceptor capabilities to engage threats in addition to addressing critical capability gaps, providing modernized technology, and increasing reliability and maintainability. FY 2024 funds in the amount of $816.663 million will fund three (3) sensors in FY 2024 to support the Pacific Deterrence initiative (PDI) to provide an Early Operational Capability. The program acquired two (2) prototype sensors in prior years to support Initial Operational Test and Evaluation (IOT&E) and transition from MTA to MCA. FY 2024 funding will fund an additional two (2) sensors to support LTAMDS testing culminating with Initial Operational Test and Evaluation (IOT&E) in FY 2026/2027. FY 2024 funds of $383.688M support the Pacific Deterrence Initiative (PDI). FY 2024 funding continues prototype Environmental Qualification testing; completes Primary Sector Operational Assessment with an Integrated Fires test campaign; completes Full Sector Contractor Verification Testing (CVT); and supports Development Test & Evaluation (DTE). Additionally, funding in FY 2024 continues software development to counter evolving threats; supports digital modeling and simulation efforts; critical Program Protection / Anti-Tamper capabilities; Large Tactical Power System (LTPS) prototype development; integration activities with the IBCS; sensor enhancements as part of the Pre-Planned Product Improvement (P3I) effort; integration with the PATRIOT family of interceptors (PAC-2 GEM-T, PAC-3, PAC-3 MSE) in support of Integrated Fires and Multi-domain Operations; and supports AMD survivability efforts. LTAMDS will transition from Middle Tier of Acquisition (MTA) to Major Capability Acquisition (MCA) in 1Q FY 2024. FY 2024 funding continues MCA walk-up activities to include required entry criteria, system verification, development of appropriate milestone documentation, and initiation of contract award activities. The total cost of the LTAMDS Middle Tier of Acquisition effort is $1,463 million RDT&E from FY 2019 to FY 2024. The LTAMDS MTA is fully funded across the Future Years Defense Program.
