Northrop Grumman Corp. Land and Self Protection Systems Division in Rolling Meadows, Ill., will provide electronic warfare radar warning receivers for U.S. Army helicopters under terms of a potential $457 million contract announced this week. Northrop Grumman will provide APR-39C(V)1 upgrade kits and APR-39A/B(V)2 radar warning receiver systems as part of a $118 million initial order from the Army Communications-Electronics command (CECOM) at Fort Monmouth, N.J.
The APR-39 provides continuous 360-degree coverage to detect and identify potentially hostile radar types automatically, as well as the radar's bearing and danger level before alerting a helicopter cockpit crew to each threat with a graphical symbol on the cockpit multifunction display or video display.
The APR-39 is designed to product a wide variety of fixed-wing and tiltrotor aircraft, as well as helicopters from today's most modern surveillance radar and radar-guided weapons threats. To date more than 6,000 APR-39 systems have been installed on domestic and international AH-1W/Z, UH-1N/Y, MV-22B, KC-130T, UH-60, OH-58D, CH-53, CH-46, AH-64A/D, and CH-47 aircraft.
