Northrop Grumman to Develop US Army Next Generation RWR

AN/APR-39E(V2) Will Employ DRE Architecture

Northrop Grumman announced on 4 March it has received a US Army award to develop the service’s next-generation radar warning receiver (RWR).

Sophisticated RF-guided weapons continue to proliferate and pose an expanding threat envelope for aviators in contested airspace. Protecting aircrews from this new generation of highly mobile anti-aircraft weapons requires the ability to track a broader variety of threats across a wider spectral range.

The AN/APR-39E(V)2, previously known as the Modernised Radar Warning Receiver, will provide a new level of precision in detecting, locating and identifying threats by combining Northrop Grumman’s digital receiver exciter (DRE) architecture with novel digital signal processing algorithms. The DRE architecture is also employed on the AN/APR-39D(V)2 RWR and other electronic warfare systems, allowing for more rapid updates to stay ahead of the threat.

The AN/APR-39E(V)2 will see more threats, including millimetre-wave radars, at greater range. That advanced level of protection is critical to our customers’ mission success,” observed Northrop Grumman Vice President, Land and Avionics C4ISR, Brent Toland.
