Northrop Grumman has received a $91 million contract from the U.S. Department of the Navy’s Naval Air Systems Command (NAVAIR) for the additional production of AN/APR-39D(V)2 digital radar warning receivers (RWR).
The contract (N00019-20-C-0054) is in support of the U.S. Navy, Army, Navy Supply Command (NAVSUP) and various Foreign Military Sales (FMS) customers.
Hardware procured on this contract includes Weapon Replaceable Assemblies and support equipment such as 55 AN/APR-39D(V)2 processors; 185 AN/APR-39D(V)2 antenna detectors; 126 AN/APR-39D(V)2 radar receivers; 46 AN/APR-39D(V)2 low band arrays; 22 AN/APR-39D(V)2 handle assemblies; 59 AN/APR-39C(V)2 processors; 236 AN/APR-39C(V)2 antenna detectors; 188 AN/APR-39C(V)2 radar receivers; 76 AN/APR-39C(V)2 upgrade kits; and 65 AN/APR-39C(V)2 circuit card assemblies. Additionally, this contract provides non-recurring engineering efforts that support production capacity to meet necessary fielding requirements.
According to the U.S. Department of Defense contract announcement, the contract is expected to be completed in March 2023.
APR-39D(V)2 is a small, lightweight all-digital multichannel radar warning receiver system that protects rotary and fixed wing aircraft from modern radio frequency (RF) threats such as radar-guided missiles and anti-aircraft artillery. The system 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.
“As the radio frequency threat grows worldwide, the protection the AN/APR-39D(V)2 provides has become essential for our warfighters and international partners,” said Ryan Tintner, vice president, navigation, targeting and surveillance, Northrop Grumman.
Underlying the system’s advanced capabilities is Northrop Grumman’s next generation electronic warfare (EW) architecture. Shared across proven electronic warfare systems in production now, it provides exceptional value and agility. Northrop Grumman EW and RWR systems are currently protecting thousands of aircraft worldwide.
The AN/APR-39D(V)2 is planned for integration on the AH-1Z Viper and AH-64E Apache attack helicopters, Airborne Reconnaissance Low-Enhanced (ARL-
