A Hawkeye successor and the longevity of the E-2

Is there a replacement for the E-2 Hawkeye?

No clear successor is identified. The E-2D Advanced Hawkeye, continuing upgrades and a possible further variant remain the options considered.

No distinct aircraft is identified as ready to replace the Hawkeye. The E-2D Advanced Hawkeye remains the reference point, with upgrades and a possible later variant discussed tentatively. The E-2 family's origins are traced to a first flight in 1960 and service entry in 1964. Successive versions explain how the familiar name has continued across decades of development. E-2Ds are described as broadly new airframes that are themselves receiving further work.
