The AN/APR-39 Digital Radar Warning Receiver Family

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 have not only sophisticated digital radar sensors and countermeasures but also a way to manage them.

AN/APR-39D(V)2 Digital Radar Warning Receiver and Electronic Warfare Management System


The Northrop Grumman APR-39D(V)2 Radar Warning Receiver (RWR)/Electronic Warfare Management System maximizes survivability by improving aircrew situational awareness via interactive management of all onboard sensors and countermeasures. The APR-39D(V)2 provides advanced RWR capability for today's and tomorrow's RF threat environment. The digital radar system features the latest technology in a small, lightweight configuration that protects a wide variety of fixed, rotary and tilt-wing aircraft from today's most modern threats.


Throughout the world, multispectral threats to aviation are becoming more sophisticated and lethal. The key to outfoxing these threats? Agility.

Smart and agile

Preserving the freedom to maneuver in contested areas has never been more important, with AESA-based air defense systems becoming widely proliferated.

Capable of using more of the spectrum than ever before and of changing frequencies on the fly, these systems are more difficult to detect and identify. But not for the AN/APR-39E(V)2, a smarter, more agile radar warning receiver that beats these systems at their own game. Its smart antenna detects agile threats over a wide frequency range, so there's nowhere in the spectrum to hide. Even millimeter wave threats are tracked by the AN/APR-39E(V)2's processor and algorithms to provide effective 360-degree warning.

Family tree

The AN/APR-39E(V)2 is the next step in the evolution of the AN/APR-39, the radar warning receiver and electronic warfare suite that has been protecting aircraft for decades. The AN/APR-39D(V)2 is a digital RWR in production now for the Army, Navy and Marines. The system is designed to maximize survivability by improving aircrew situational awareness via interactive management of all onboard sensors and countermeasures. The AN/APR-39E(V)2 builds on the proven technologies built into the APR-39D(V)2.

Airborne electronic warfare expertise

Northrop Grumman's roots in electronic warfare are deep, with some of the world's most trusted and advanced systems flying today, including Falcon Edge for the F-16 Block 60 and the EA-18G Airborne Electronic Attack Kit.
