Power for the Douglas X-3 "Stiletto" was provided by two XJ34-WE-17s of 3,370 lbs. The McDonnell F2H-2 Banshee fighter jet of 1950 had 2 Westinghouse J34 WE-34 engines with 3000 lbs thrust. thrust, while the XF-88B used two XJ34-WE-19s, each rated at 3,250 lbs. thrust, powered the tiny McDonnell XF-85 "Goblin." The McDonnell XF-88A used two J34-WE-15 engines, each rated at 3,150 lbs. Several different series J34s were used in Air Force experimental aircraft during the 1948-1953 period. Model W-340 was satisfactory for operation in icing conditions. Model J34-WE-34 had no provisions for anti-icing the engine inlet and waa not approved for use in icing conditions.
The -2 engines incorporate Steward-Davis accessory gear box drive shaft SDD-410A. The J34-WE-34-1, J34-WE-36-1 and the W340-1 engines incorporate Steward-Davis accessory gear box drive shaft SDD-472. The -15, -17, and -19 engines were fitted with an afterburner for additional thrust when needed. of thrust (depending on engine series) and was twice as powerful as its predecessor. It was an axial flow turbojet with eleven stage compressor double annular combustion chamber, two stage turbine.
Developed by Westinghouse Electric Corporation in the late 1940s, the J34 engine was an enlarged version of the earlier Westinghouse J30.
