Program Narratives

Description— BMDS Sensors

The decrease from Fiscal Year (FY) 2025 to FY 2026 reflects the procurement completion of Radar 13 Initial Spares and Power Converters. The AN/TPY-2 radar is an integral component of the Missile Defense System layered network of sensors. It is transportable and can be configured to operate as either a Terminal High Altitude Area Defense (THAAD) Fire Unit Radar (terminal mode) or a Forward-Based Radar. The forward-based AN/TPY-2 provides detection and tracking during the boost phase. This significantly reduces the uncertainty in target discrimination and reaction time, increasing the probability of a successful Missile Defense System engagement. In forward-based mode, the AN/TPY-2 provides acquisition and track data via the Missile Defense System Command, Control, Battle Management and Communications and Link 16 to the Aegis Missile Defense System for cueing. The AN/TPY-2 used in terminal mode is an integral component of the THAAD Battery. The THAAD battery radar can track multiple threats and multiple interceptors during engagements in the terminal phase. It provides surveillance, acquisition, tracking, discrimination, interceptor communications, and hit assessment data collection for fire control. Prior year procurement funding acquired six (6) AN/TPY-2 Radars required to complete the THAAD Battery acquisitions. "Procurement Quantity" and "Flyaway Unit Cost" represent AN/TPY-2 radar systems (e.g. one (1) Antenna Equipment Unit (AEU), one (1) Cooling Equipment Unit (CEU), one (1) Electronic Equipment Unit (EEU), and two (2) Prime Power Units (PPU)) only, but the "Net Procurement" cost plus the Initial Spares amount includes the costs of all hardware. The AEU Transformer and PPU procurement addressed the obsolescence of major end items and was completed in FY 2020. The AN/TPY-2 EEU Modification Kits and Radar Field Upgrade Kits provided updated processing capabilities and added a cybersecurity server in the EEUs in both Terminal and Forward-based modes. The AEU transformers include design improvements to extend the life of this mission-critical component. The Next Generation server procurement updates the fleet's existing servers and enhances the fleet's cybersecurity protection and processing capability. The CEU Retrofit Kit and Refurbishment procurement modernize the CEU, replacing obsolete equipment and adding performance enhancements that increase radar capabilities while bringing the CEUs into a common, more reliable configuration. The Digital Receiver/Exciter (DREX) kit procurement will upgrade the current analog Receiver/Exciter technology to a modern digital capability, increasing reliability and spares availability for the fleet. The Advanced Signal Processor (ASP) kit procurement, when used with the DREX, will upgrade the system waveform processing capability to align signal-processing capability with advanced waveform types and provide a scalable, distributed processing solution and enhanced capability against emerging threats. The AN/TPY-2 Line Replacement Unit (LRU) obsolescence mitigation program provides for kits of LRUs that become obsolete as the AN/TPY-2 system ages. The program mitigates unforeseen supply chain risks and improves repair cycle time. The AEU Refurbishment kit and program replaces obsolete electrical equipment and refreshes the unit's core structure, bringing the AEUs into near "zero-hour" operational readiness.

Justification— BMDS Sensors

The decrease from Fiscal Year (FY) 2025 to FY 2026 reflects the procurement completion of Radar 13 Initial Spares and Power Converters. FY 2026 procurements include: - Six (6) ASP for DREX. - Three (3) AN/TPY-2 LRU Kits. - Two (2) CEU Refurb. - One (1) CEU Retrofit kit. FY 2025 procurements include: - Seven (7) DREX kits. - Seven (7) Next Generation Servers (Cyber). - One (1) CEU Retrofit kit. - Radar 13 Initial Spares. - Power Converters. FY 2024 procurements included: - Next Generation Servers (Cyber). - Alternating Current/Direct Current (AC/DC) Converters. The prior year's quantity above reflects the procurement of complete radars only. Seven (7) of the thirteen (13) AN/TPY-2 Radars procured to date were funded with Research Development Test and Evaluation in Program Element 0603884C, therefore, not included in the costs above.
