DREXR upgrade flight trials completed on US Navy E-2D Advanced Hawkeye

Lockheed Martin and Northrop Grumman have completed flight trials of the Digital Receiver Exciter Recorder (DREXR) upgrade on the US Navy’s E-2D Advanced Hawkeye.

DREXR consolidates the functions of the existing Exciter and Receiver subsystems into a single compact unit, supporting next-generation radar performance and prolonging the operational lifespan of the US Navy’s main airborne early warning platform.

During the flight test campaign, the team validated key capabilities including wideband transmission and reception, independent transmission for each radar element, and software-defined waveform functionality.

Data collected from the integrated recorder will assist with mission analysis and the continued development of advanced capabilities, including applications involving AI.

These tests improve the US Navy’s capacity to detect, track, and respond to emerging threats in challenging environments, Lockheed Martin stated.

Lockheed Martin radar and sensor systems vice president Rick Cordaro said: “The successful DREXR flight tests demonstrate our commitment to keeping the E-2D Advanced Hawkeye at the forefront of airborne early warning and battle management.

“By modernising this proven platform, we are ensuring it remains a critical enabler for force protection, command and control, and mission success in today’s increasingly complex threat environment.”

The E-2D Advanced Hawkeye is an airborne early warning and battle management platform for the US Navy. It incorporates APY-9 radar, mission computer, and sensor suite, enabling operations spanning multiple domains from both sea and land.

The flight tests also enhance the aircraft’s role in defending the Carrier Strike Group.

Commanders benefit from the upgrade through improved situational awareness and faster decision-making, which contributes to operational effectiveness throughout the battlespace.
