3D Expeditionary Long-Range Radar

The 3D Expeditionary Long-Range Radar (3DELRR) program is an initiative by the Air Force to replace the outdated AN/TPS-75 radar system. Its primary goal is to provide an advanced, long-range, ground-based radar system that enhances detection, identification, tracking, and reporting of aerial targets. This system is crucial for supporting the Joint Force Air Component Commander (JFACC) by delivering a precise and real-time air picture that can operate under various environmental and operational conditions.

The 3DELRR system features the TPY-4 radar and includes essential components such as Prime Movers, Generators, and other equipment necessary for its operation. These components are sent directly to operational units or integrated into the radar system by Lockheed Martin before deployment. The program aims to improve battlefield awareness by detecting highly maneuverable airborne targets with small radar cross-sections. It also addresses reliability and maintainability issues while ensuring transportability and sustainability.

In alignment with Section 1815 of the FY 2008 National Defense Authorization Act, the 3DELRR program supports both active and reserve components of the Armed Forces. It plays a vital role in homeland defense missions, domestic emergency responses, and military support to civil authorities. The procurement plan for FY2025 includes acquiring three TPY-4 units along with necessary logistics and program management support to ensure seamless integration into existing defense frameworks.

The 3DELRR program represents a significant advancement in radar technology for the Air Force. It aims to enhance national security capabilities while addressing current limitations in radar systems. By investing in this technology, the Air Force seeks to maintain its strategic edge in airspace monitoring and control amidst evolving global threats.
