To meet a US. Navy requirement of 1954 for a carrier based airborne early warning plane, Grumman began to develop a G-117 version of the S2F anti submarine plane. The type first flew during March 1957 as an aerodynamic prototype based on the airframe of a TF-1 Trader, itself the carrier onboard delivery version of the S2F. The type was fitted with a giant type radar dome above the fuselage, and adequate directional control with this arrangement was ensured by the revision of the tail unit with shortened central fin and two endplate vertical surfaces. Deliveries of 88 WF-2s began in February 1958. and these "willy Fudds" entered first line service with the VAW-11 and VAW-12 squadrons in 1960. The radar dome carried APS-82 surveillance radar development by Hazel tine, for all weather use. The equipment was operated by two specialists, with the co-pilot occupying a fold out seat between them as tactical co-ordinator. In 1962 the type was redesigned E-1B Tracer, and from 1965 it was replaced  by the altogether from capable Grumman E-2 Hawkeye.
