Northrop Grumman has rolled out the first E-2D Advanced Hawkeye, the latest version of the US Navy’s carrier-based airborne early warning aircraft. The first of two test aircraft was revealed at Northrop’s St Augustine, Florida plant.

While externally similar to today’s E-2C, the E-2D has a new Lockheed Martin APY-9 radar with an L-3 Randtron rotodome antenna that combines mechanical rotation with electronic scanning. This provides 360º coverage while allowing operators to focus the radar on areas of interest.


The E-2D also features new operator workstations, mission data processors, electronic support measures and satellite communications. Electrical and cooling systems are improved.

The airframe is strengthened for a higher carrier landing weight and a new glass cockpit is installed. The E-2D is powered by Rolls-Royce T56-427A turboprops driving eight-blade Hamilton Sundstrand NP2000 propellers.

Northrop is working under a $2 billion system development and demonstration contract. Flight testing will begin late this year and the Advanced Hawkeye is scheduled to enter service with the US Navy in 2011.
