The Northrop Grumman E-2 Hawkeye, a carrier-based airborne early warning (AEW) aircraft, first flew in October 1960. It is the first aircraft designed specifically for AEW and has been a key component of US Navy carrier strike groups. The E-2 provides radar detection and command and control for naval operations.

The E-2 Hawkeye, with its distinctive rotating radar dome, is a symbol of naval aviation and the technological sophistication of modern air warfare. It appears in naval aviation literature and poetry, often representing the 'lookout' of the fleet. The name 'Hawkeye' itself evokes a sense of all-seeing vigilance.
