Three Dimensional Expeditionary Long-Range Radar (3DELRR)

3DELRR

Lockheed Martin is currently developing its technology solution for the Three Dimensional Expeditionary Long-Range Radar (3DELRR), the U.S. Air Force's next-generation mobile, long-range surveillance and ballistic missile defense radar. Lockheed Martin’s fully functional 3DELRR prototype is currently tracking air targets as the company awaits the next phase in the Air Force acquisition program. 

The 3DELRR will serve as the principal long-range, ground-based sensor for detecting, identifying, tracking, and reporting aircraft and missiles for the Air Force. The radar will bring a significant capabilities leap for the Air Force’s critical long-range mission and allow the service to continue to outpace the rapid development of new airborne threats and their expanding reach.  The system will replace the Air Force’s AN/TPS-75 air surveillance radar. The Marines also are evaluating the system as a replacement for their AN/TPS-59 ballistic missile defense radar.

Lockheed Martin has made significant investments in 3DELRR to reduce risk and drive affordability, including the design and production of an operational radar prototype. We have applied both new technology advances and our knowledge gained from decades of experience developing and maintaining more than 170 long-range surveillance radars currently operational around the world.

Lockheed Martin’s radar design addresses 100 percent of 3DELRR requirements, including critical extended air surveillance reach for early warning from threats, such as aircraft and ballistic missiles.
