PATUXENT RIVER NAS, Md. – Military aviation experts at Northrop Grumman Corp. are providing new embedded computing and RF and microwave components to increase production capability of the U.S. Navy AN/APR-39 family of airborne electronic warfareradar warning receiveravionics.

Officials of the Naval Air Systems Command at Patuxent River Naval Air Station, Md., announced a $124.7 million contract Thursday to the Northrop Grumman Mission Systems segment in Rolling Meadows, Ill., for a variety of electronic components for the AN/APR-39D(V)2 -- the latest upgrade to the AN/APR-39 radar warning receiver.

The AN/APR-39 family of radar warning receivers is for a variety of Navy fixed-wing aircraft, helicopters, and naval vessels. It detects radar threats to aircraft, such as radar ground sites and particularly radar-guided missiles.

Navy avionics officials are ordering these new electronic components to increase production capacity to meet necessary fielding requirements for the AN/APR-39D(V)2 for the U.S. Navy, Army, and the governments of Japan, Austria, and Canada.

For the AN/APR-39 radar warning receiver, Northrop Grumman will provide:

-- 127 D(V)2 processors;
-- 462 D(V)2 antenna detectors;
-- 290 D(V)2 radar receivers;
-- 121 D(V)2 low band arrays;
-- 168 D(V)2 battery handle assemblies;
-- 20 D(V)2 circuit card assemblies;
-- 40 C(V)2 processors, 63 C(V)2 antenna detectors;
-- 131 C(V)2 radar receivers;
-- 19 C(V)2 upgrade kits; and
-- two test stations in support of the AN/APR-39 program.

In mid-2012 the Navy asked Northrop Grumman to upgrade the Navy's AN/APR-39 family of radar warning receivers with new digital signal processing (DSP) capability based on 6U-form-factor circuit cards.

The APR-39 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 system 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 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, Northrop Grumman will do the work in Rolling Meadows, Ill.; Woburn, Mass.; Lansdale, Pa.; Longmont, Colo.; Menlo Park, Calif., and other U.S. locations, and should be finished by February 2020.
