Three Dimensional Long-Range Radar (3DELRR)

The Three Dimensional Long-Range Radar (3DELRR) program is a significant initiative by the United States Air Force to replace the aging AN/TPS-75 radar system. The primary goal is to develop and deploy a modern radar system capable of detecting, identifying, tracking, and reporting aerial targets for the Joint Force Air Component Commander. This system aims to enhance battlefield awareness by providing precise, real-time air pictures, crucial for controlling aircraft under various environmental and operational conditions.

The program focuses on improving radar capabilities through several specific goals. These include developing electronic protection techniques, classification and clutter algorithms, and enhancing radar capabilities across diverse operating environments. Additionally, it aims to integrate with other military branches through interfaces like the Integrated Fire Control Network with the Army and Cooperative Engagement Capability/Composite Tracker Network with the Navy and Marine Corps. This integration ensures seamless communication and coordination among different branches of the military.

In FY2025, efforts will continue to advance the capabilities of the TPY-4 radar component of the 3DELRR system. This includes ongoing test and evaluation activities to assess performance, cybersecurity posture, mobility, and maintenance requirements. The program also plans to finalize technical manuals and training materials while conducting test readiness reviews prior to specific test events. These activities are essential for supporting fielding decisions and ensuring that future requirements based on mission needs are effectively developed and implemented.

The acquisition strategy for 3DELRR involves transitioning from a Middle Tier of Acquisition Rapid Prototyping effort to a Major Capability Acquisition program by early 2025. This transition marks a shift from prototype development to production of initial units. Program management is overseen by PEO Digital at Hanscom AFB, MA, with contracting authority provided by the Air Force Life Cycle Management Center at Wright-Patterson AFB, OH. The strategy ensures that all necessary resources are allocated efficiently to meet the program's objectives while addressing any funding shortfalls through potential future requests or alternative pathways.
