The AN/APR-39E(V)2 uses a smart antenna and advanced processing to detect a wider range of radio frequency threats and keep warfighters safe.

Northrop Grumman Corporation has been awarded a multi-year contract to produce initial production units of the AN/APR-39E(V)2 radar warning receivers for the US Army.

Northrop Grumman's AN/APR-39E(V)2 is a fully digital radar warning receiver with the instantaneous bandwidth and frequency coverage to protect against the most advanced radar threats.

  • Clutter reduction and threat geolocation capabilities provide a significant advance in survivability and the ability to turn threats into targets.
  • Open architecture design enables growth to future electronic warfare capabilities.


James Conroy, vice president, navigation, targeting and survivability, Northrop Grumman: “The APR-39E(V)2 is a sophisticated, more agile radar warning receiver that outpaces emerging threats. It provides a generational leap in capability over previous radar warning systems.”

Details on AN/APR-39E(V)2:

Northrop Grumman has been awarded a five-year contract for production of the AN/APR-39E(V)2. The system is a significant advance in the evolution of the widely installed AN/APR-39 radar warning receiver family. The system's smart antenna detects threats over a wide range of the spectrum, including millimeter wave frequencies, to give warfighters a broader view of potential threats.

Another advantage of the AN/APR-39E(V)2 is its readiness to be the survivability suite controller in multi-domain, large-scale combat operations. The system is capable of sharing threat data, enhancing survivability and mission effectiveness.

Shared across a family of electronic warfare systems, this pioneering technology can scale to virtually any platform or mission, including current fleet and future platforms. Northrop Grumman's sensors and electronic warfare systems give warfighters superiority across the spectrum and allow for faster, more informed decisions.
