Northrop Grumman to Upgrade US Military’s Radar Warning Receiver Capability to Digital Standard

Northrop Grumman Corporation received a $91 million contract for the additional production of AN/APR-39D(V)2 digital radar warning receivers (RWR).

Small and lightweight, the system protects rotary and fixed wing aircraft from modern radio frequency (RF) threats such as radar-guided missiles and anti-aircraft artillery. The all-digital, multichannel APR-39D(V)2 RWR monitors a 360° spherical coverage area to detect threats and determine their identity, bearing and lethality. The system can automatically initiate optimal defensive measures and has an immediate growth capability for RF countermeasures.

The AN/APR-39D(V)2 is planned for integration on the AH-1Z, AH-64E, ARL-E, MV-22, UH-1Y and CH-53E/K.
