Jan. 9 (UPI) -- The Air Force is planning to cancel its contract with Raytheon for next-generation, ground-based radar.
The Three-Dimensional Expeditionary Long Range Radar, or 3DELRR, system was to be a gallium nitride-based radar that operated on the C-band. It was intended to replace the AN/TPS-75 ground-based radar used to track airborne targets.
