Lockheed Martin [NYSE: LMT] successfully operated its full-scale prototype long-range air surveillance radar during a recent capability demonstration to the U.S. Air Force. The Three-Dimensional Expeditionary Long-Range Radar (3DELRR) will serve as the principal Air Force long-range, ground-based sensor for detecting, identifying, and reporting aerial targets. This next-generation system will replace the Air Force’s AN/TPS-75 air search radar.
