The $91m contract for AN/APR-39D(V)2 follows the completion of engineering and manufacturing development activities.
The small, lightweight system safeguards rotary and fixed-wing aircraft from radar-guided missiles and anti-aircraft artillery and other modern radio frequency (RF) threats.
It can provide 360° coverage to detect and identify radio-frequency threats to an aircraft while determining the identity, bearing and lethality.

Northrop Grumman has planned to integrate the AN/APR-39D(V)2 on the AH-1Z, AH-64E, ARL-E, MV-22, UH-1Y and CH-53E/K aircraft.
Northrop Grumman navigation, targeting and survivability vice-president Ryan Tintner said: “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.”
In March last year, the US Army selected Northrop Grumman to develop the next-generation radar threat warning sensors.
