The E-2 Hawkeye is the Navy's all-weather, carrier-based tactical battle management airborne early warning, command and control aircraft. Its missions also include surface surveillance coordination, air interdiction, offensive and defensive counter air control, close air support coordination, time critical strike coordination, search and rescue airborne coordination and communications relay. An integral component of the Carrier Strike Group air wing, the E-2C uses computerized radar, Identification Friend or Foe and electronic surveillance sensors to provide early warning, threat analysis against potentially hostile air and surface targets.
E-2D Advanced Hawkeye (AHE) uses the E-2C Hawkeye 2000 configuration as a baseline, it features a state of the art radar with a two generation leap in capability and upgraded aircraft systems that improves supportability and increases readiness. Key AHE program objectives include improved battle space target detection and situational awareness, support of Theater Air and Missile Defense (TAMD) operations, and improved Operational Availability. The Advanced Hawkeye provides advance warning of approaching enemy surface units, cruise missiles and aircraft, to vector interceptors or strike aircraft to attack, and it also provides area surveillance, intercept, communications relay, search and rescue and strike and air traffic control.
