Description
Mission — Three Dimensional Expeditionary Long Range Radar
The Three-Dimensional Expeditionary Long-Range Radar (3DELRR) program develops the AN/TPY-4 system which is the designated replacement for the AN/TPS-75 radar. The AN/TPS-75 is an outdated and unsustainable system which was first fielded in the early 1970s. The 3DELRR system will be the United States Air Force's (USAF's) principal long-range, ground-based sensor for detecting, identifying, tracking, and reporting aerial tracks for the Joint Force Air Component Commander (JFACC). The 3DELRR system consists of the AN/TPY-4 radar and associated ground support equipment which includes Prime Movers, Generators, and other smaller mission support items. When fielded, the 3DELRR system will provide multiple benefits and increased capabilities to the USAF and the Joint Services, including: the ability to detect and track modern and emerging highly maneuverable, small radar cross-section airborne target; greater battlefield and battlespace awareness through a precise, real-time air picture of sufficient quality to control individual aircraft under a wide range of environmental and operational conditions; and increased reliability, operational availability, maintainability, transportability, survivability, and sustainability. FY 2026 funding will continue system capability development, which include development of electronic protection (EP) techniques, continued software fixes and Non-Recurring Engineering (NRE) costs. Additionally, FY 2026 funding will support continued test and evaluation activity, to include Initial Operational Test and Evaluation (IOT&E) of the system. This program element may include necessary civilian pay expenses required to manage, execute, and deliver weapon system capability. The use of such programs funds would be in addition to the civilian pay expenses budgeted in program element 0605827F, 0605828F, 0605829F, 0605831F, 0605832F, 0605833F, 0605898F, 0606398F. In FY 2025 $0.12 million was expended for civilian pay expenses in this program element, and in FY 2026 $0.17 million is forecasted for civilian pay expenses in this program element. This effort is in Budget Activity 4, Advanced Component Development and Prototypes (ACD&P), because efforts are necessary to evaluate integrated technologies, representative modes or prototype systems in a high fidelity and realistic operating environment.
