The Westinghouse J30, initially known as the Westinghouse 19XB, was a turbojet engine developed by Westinghouse Electric Corporation.
 It was the first American-designed turbojet to run, and only the second axial-flow turbojet to run outside Germany.
The General Electric GE4 turbojet engine was designed in the late 1960s as the powerplant for the Boeing 2707 supersonic transport.
 The GE4 was a nine-stage, single-shaft, axial-flow turbojet based largely on the General Electric YJ93 which powered the North American XB-70 bomber.
 The GE4 was the most powerful engine of its era, producing 50000 lbf dry, and 65000 lbf with afterburner.
 The Boeing 2707 was cancelled in 1971, putting an end to further work on the GE4.
The General Electric YJ93 turbojet engine was designed as the powerplant for both the North American XB-70 Valkyrie bomber and the North American XF-108 Rapier interceptor.
 The YJ93 was a single-shaft axial-flow turbojet with a variable-stator compressor and a fully variable convergent/divergent exhaust nozzle.
 The maximum sea-level thrust was 28,800 lbf .
The SNECMA ATAR 101 is a French axial-flow turbojet engine built by SNECMA.
 It was derived from engines and design work carried out at BMW in Germany during World War II, and extensively developed though a progression of more powerful models.
 The name is derived from its original design group, Atelier Technique Aéronautique de Rickenbach employing Herman Östrich and many of the wartime BMW gas turbine design group as well as other German engine design teams.
 The ATAR 101 powered many of the French post-war jet aircraft, including the Vautour II, Étendard IV, Super Mystère B2, and the Mirage III-001, prototype of the Mirage III series.
The BMW 018 ("RLM" designation BMW 109-018) was an early axial-flow turbojet engine project by BMW AG in Germany.
The Dobrynin RD-7 or "VD-7" is a Soviet axial-flow turbojet engine.
The Pratt & Whitney J57 (company designation: JT3C) was an axial-flow turbojet engine developed by Pratt & Whitney in the early 1950s.
 The J57 (first run January 1950) was the first 10,000 lbf (45 kN) thrust class engine in the United States.
 The J57/JT3C was developed into the J75/JT4A turbojet, JT3D/TF33 turbofan and the PT5/T57 turboprop.
The Westinghouse J34, company designation Westinghouse 24C, was a turbojet engine developed by Westinghouse Aviation Gas Turbine Division in the late 1940s.
 Essentially an enlarged version of the earlier Westinghouse J30, the J34 produced 3,000 pounds of thrust, twice as much as the J30.
 Later models produced as much as 4,900 lb with the addition of an afterburner.
 It first flew in 1947.
 The J46 engine was developed as a larger, more powerful version of Westinghouse's J34 engine, about 50% larger.
The Wright J65 was an axial-flow turbojet engine produced by Curtiss-Wright under license from Armstrong Siddeley.
 A development of the Sapphire, the J65 powered a number of US designs.
The Pratt & Whitney J75 (company designation: JT4A) was an axial-flow turbojet engine first flown in 1955.
 A two-spool design in the 17,000 lbf (76 kN) thrust class, the J75 was essentially the bigger brother of the Pratt & Whitney J57 (JT3C).
 It was known in civilian service as the JT4A, and in a variety of stationary roles as the GG4 and FT4.
