||While the external appearance is similar to the E-2C, the systems and capabilities which the E-2D Advanced Hawkeye contains are completely redesigned. At the heart of the aircraft is the new radar, the APY-9, designed and built by Lockheed Martin Corporation. It can "see" smaller targets and more of them at greater ranges than the E-2C. The new rotodome, developed by L-3 Communications Randtron Antenna Systems, contains the critically important, continuous, 360-degree scanning capability, while adding an electronically scanned array. This system allows operators to focus the radar on selected areas of interest.
Hawkeye operators will have new radar system workstations, integrated satellite communications capabilities and other tools to better manage the battle space and provide warfighters with expanded situational awareness and information to complete their missions.
An additional new feature of the E-2D is the state-of-the-art glass cockpit that replaces prior-generation Hawkeye displays and avionics systems. One of the advantages is that pilots can also serve as weapon system operators.
