Eventually, the Grumman C-2 Greyhound would be created from the E-2. 313 E-2 Hawkeye aircraft have been constructed to date. The E-2 has been dubbed "Super Fudd" and "Hummer," the latter due to the noises made by its engine. The avionics package is what separates the E-2D Hawkeye from the previously stated E-2D Advanced Hawkeye. Along with an improved mission computer, radar suite, flight management, integrated satellite systems, new engines, and a glass cockpit to facilitate aerial refueling, the new avionics suite includes the APY-9 radar.
