Three-Dimensional Expeditionary Long-Range Radar (3DELRR)

The Three-Dimensional Expeditionary Long-Range Radar (3DELRR) is required to replace the AN/TPS-75 radar as the principal USAF long-range, ground-based sensor for detecting, identifying, tracking, and reporting aircraft and missiles in support of the Joint Forces Air Component Commander through the Ground Theater Air Control System. It is possible that the USMC will align their AN/TPS-59 product improvement/upgrade initiative with this effort. The primary mission of the 3DELRR will be to provide long-range surveillance, control of aircraft, and theater ballistic missile detection. The 3DELRR will provide air controllers with a precise, real-time air picture of sufficient quality to conduct close control of individual aircraft under a wide range of environmental and operational conditions.

In the case of theater missile defense operations, the new radar will have the capability to detect, track, and disseminate target information to respective command and control nodes such as the USAF Control and Reporting Center to disseminate for warning and engagement. Similarly, the joint targeting process will benefit from trajectory information provided by the 3DELRR, which will include launch and impact location. The 3DELRR will correct current radar system shortfalls by providing the capability to detect and report highly maneuverable, small radar cross section targets as well as classify and determine the type of a non-cooperative aircraft. It will also mitigate most of the sustainability and maintainability concerns which plague the current system.

This new radar will give the GTACS real-time display of all air activity and be rugged enough to support a wide range of deployed operations in all types of weather and terrain conditions. It will also provide sufficient advanced warning and target information to allow for threat evaluation and responsive action.
