In response to the Special Committee on Jet Propulsion of the National Advisory Committee for Aeronautics, the Westinghouse Research Laboratories proposed development of a turbojet engine, but started development without a contract. The 4,893 N (1,100 lb) thrust 19A Yankee (military designation J30), the first all-American-designed turbojet engine flew on a Chance Vought FG-1 Corsair testbed aircraft in 1944 in its original function as a booster engine.

In succession, the Westinghouse J46, with a thrust of 22,240 N (5,000 lb) without afterburner, was planned as a replacement for the Westinghouse J34. With three bearings instead of two, as had the J40, it passed the 150 hour qualification test in 1953. It only had limited production, primarily for the Vought F7U Cutlass.

With afterburner, the J46-WE-8 powered the Chance Vought A2U-1 and F7U-3 Cutlass as well as the Convair XF2Y-1 Sea Dart. This J46-WE-8 was accepted for service in 1955 and was installed in a Chance Vought F7U-3M aircraft.
