Background Continual improvements in airborne radars through 1956 led to the construction of AEW airplanes by several different countries and several different armed forces. The functions of command and control and sea and air surveillance were also added. The first carrier-based aircraft to perform these missions for the U.S. Navy and its allies was the Douglas AD Skyraider, which was replaced in US Navy service by the Grumman E-1 Tracer, which was a modified version of the S-2 Tracker twin-engine anti-submarine warfare aircraft, where the radar was carried in an aerofoil-shaped radome carried above the aircraft's fuselage.Godfrey 1977, pp. 7–8.
