AN/APR-39 Radar Warning Receiver (RWR)

Be the hunter, not the prey

The electronic battlefield becomes more complex every day, dominated by an array of multispectral (RF/IR/EO) threats that jeopardize aircrew survival. To survive, aircrews must not only have sophisticated sensors and countermeasures, but a way to manage them as well.

The AN/APR-39 series is a family of RWRs  fitted to a variety of fixed-wing aircraft, helicopters and naval vessels. Current configurations are APR-39A(V)2, and APR-39B(V)2. Both variants cover the frequency range from C to K band, and provide conventional radar warning.

APR-39A(V)2 Threat Warning System

The APR-39A(V)2 is used by the US Army and US Marine Corps Helos and Fixed Wing aircraft. In addition to threat warning, it acts as a control for the EW survivability suite. It is integrated with the laser warning receiver and missile warner.

This low cost system provides state-of-the-art technology combining lightweight and low power consumption. The APR-39A(V)2's highly sensitive, multireceiver architecture provides rapid identification and continuous 360º threat warning for today’s complex battlefield.

APR-39B(V)2 Radar Warning Receiver/Electronic Warfare Management System

The APR-39B(V)2 RWR provides continuous 360º coverage to automatically detect and identify threat types, bearing and lethality, then alerts the crew to each threat with a graphical symbol on the cockpit multifunction display (MFD) or video display. The system also gives the aircrew synthetic speech audio threat warnings.

The APR-39B(V)2 also functions as an EWMS, serving as the heart of Northrop Grumman's Suite of Integrated Sensors and Countermeasures (SISCM),  which integrates and displays data from onboard sensors (RF/IR/EO).
