According to a recent press release, the Army and Navy have supplied funding to Northrop Grunman to develop and test pre-production units of the APR-39D(V)2 radar warning receiver (RWR)/electronic warfare management system (EWMS).
Under the terms of the agreement with the U.S. Army and Navy, Northrop Grunman will produce 18 APR-39D(V)2 units which are expected to be delivered by late 2014. Platform and hardware-software integration testing is set to begin in early 2015. The APR-39D(V)2 RWR/ EWMS is designed to improve aircrew situational awareness through interactive management of all onboard sensors and countermeasures. The system is designed to offer crews 360-degree coverage to automatically detect and identify threat types, bearing, and lethality. It features the latest technology in a small, lightweight configuration that protects a wide variety of fixed-, rotary- and tilt-wing aircraft.
Janine Nyre, vice president of radio frequency combat information systems at Northrop Grumman, said about the system development in the release, "Our APR-39D(V)2 merges the baseline capability of previous systems with the Northrop Grumman digital receiver technology to provide advanced capability for today's and tomorrow's threat environment. This lightweight system maintains interfaces with legacy systems and includes flexibility for future growth enhancements."
To date, more than 7,000 APR-39 systems have been implemented onboard 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. The agreement between Northrop Grunman and the United States Army and Navy will ensure the hardware and software implemented on aircrafts go through integration testing processes to improve quality.
