Army picks L3Harris Randtron for radar warning receiver antennas for airborne electronic warfare (EW)
ABERDEEN PROVING GROUND, Md. – U.S. Army RF surveillance experts needed spare antennas for the AN/APR-39 radar warning receiver. They found their solution from L3Harris Randtron Antenna Systems in Menlo Park, Calif.
Officials of the U.S. Defense Logistics Agency Land and Maritime division at Aberdeen Proving Ground, Md., on behalf of the Army, have announced a $33.6 million contract to Randtron Antenna for AN/APR-39 radar warning receiver antenna spares.
The Northrop Grumman Mission Systems segment in Rolling Meadows, Ill., builds the AN/APR-39 family of radar warning receivers, which detect radar threats to aircraft, such as radar ground sites and particularly radar-guided missiles, and provides 360-degree coverage around the aircraft. When the system detects radar threats, it alerts the aircraft crew to each threat with a graphic symbol on the cockpit display.
The AN/APR-39D(V)2 RF and microwave system is the latest upgrade to the AN/APR-39 radar warning receiver that corrects deficiencies and enhances capability in the same weight and dimensions as the previous system. The upgrade calls for a new digital receiver for the AN/APR-39D(V)2.
The APR-39 provides the pilot and air crew with information on threat types, bearing, and the severity of the threat. The system also gives the aircrew synthetic speech audio threat warnings.
The APR-39 electronic warfare (EW) system also functions as an electronic warfare management system, and serves as the heart of Northrop Grumman's suite of integrated sensors and countermeasures that integrates and displays data from onboard sensors radio frequency and electro-optical sensors.
On this contract Randtron Antenna will do the work in Menlo Park, Calif., and should be finished by March 2027.
