The Grumman E-2 Hawkeye is an American all-weather, aircraft carrier-based tactical Airborne Early Warning (AEW) aircraft. The twin turboprop aircraft was designed and developed in the 1950s by Grumman for the United States Navy as a replacement for the E-1 Tracer. The aircraft has been progressively updated with the latest variant, the E-2D, first flying in 2007.
The aircraft was nicknamed "Super Fudd" because it replaced "Willy Fudd" (the E-1 Tracer). In the present day, it is most commonly nicknamed the "Hummer" due to the distinctive sound of its twin turboprop engines.
