BMDS AN/TPY-2 Radars

The BMDS Sensors program, managed by the Missile Defense Agency (MDA), is a critical line item within the Department of Defense's procurement budget. It specifically supports the acquisition and modernization of sensor systems for the Ballistic Missile Defense System (BMDS). The primary objective of this program is to ensure the operational readiness and technological relevance of the AN/TPY-2 radar fleet, which serves as a cornerstone of the United States' layered missile defense architecture. These sensors provide both forward-based and terminal-phase detection, tracking, and discrimination capabilities, directly supporting systems such as Terminal High Altitude Area Defense (THAAD) and Aegis Ballistic Missile Defense.

The AN/TPY-2 Radar Procurement line focuses on acquiring and maintaining the hardware necessary for BMDS operations. This includes the procurement of complete radar systems, each comprising an Antenna Equipment Unit (AEU), Cooling Equipment Unit (CEU), Electronic Equipment Unit (EEU), and Prime Power Units (PPUs). The program has completed the acquisition of radars to fulfill THAAD battery requirements, with earlier radars funded through research and development appropriations. The procurement also addresses hardware obsolescence and reliability by incorporating design improvements and modernizing critical components, such as AEU transformers and CEU retrofit kits.

The Upgrade and Modernization Initiatives within the BMDS Sensors program are aimed at enhancing radar performance and cybersecurity. Efforts include the deployment of Next Generation Servers and cybersecurity enhancements for the EEU, ensuring robust protection against emerging cyber threats. The Digital Receiver/Exciter (DREX) kit upgrades analog receiver technology to digital, improving reliability and spares availability. Additionally, the Advanced Signal Processor (ASP) kit, when paired with DREX, advances signal processing capabilities to support new waveform types and scalable distributed processing. These upgrades increase effectiveness against evolving missile threats.

The Obsolescence Mitigation and Refurbishment activities are designed to sustain the operational lifecycle of the AN/TPY-2 fleet. Line Replaceable Unit (LRU) obsolescence kits provide replacement for aging or obsolete parts, reducing supply chain risks and repair cycle times. The AEU refurbishment program replaces outdated electrical equipment and refreshes the unit's core structure, maintaining zero-hour readiness and extending the service life of mission-critical components. These efforts are essential for ensuring that the radar systems remain reliable and capable in the face of technological and operational challenges.

The Cooling Equipment Unit (CEU) Modernization line item includes both refurbishment and retrofit kits to address obsolete equipment and add performance enhancements. These upgrades bring CEUs into a common, more reliable configuration, increasing overall radar capability and reducing maintenance requirements. The procurement of CEU fan motors and retrofit firewall kits further supports the reliability and security of the cooling infrastructure, which is vital for sustained radar operations in diverse environments.

The Critical Spares and Support component of the BMDS Sensors program ensures that essential spare parts and support resources are available for ongoing maintenance and rapid repair of radar systems. Initial spares and AC/DC converters are procured to support new radar deployments and maintain operational continuity. Program support funding is allocated for contractor certification, technical assistance, and other activities necessary to sustain the BMDS sensor fleet's readiness and effectiveness.
