The J57 (first run January 1950[1]) was the first 10,000 lbf (45 kN) thrust class engine in the United States. The J57/JT3C was developed into the J52 turbojet, the J75/JT4A turbojet, the JT3D/TF33 turbofan, and the XT57 turboprop (of which only one was built).[2] The J57 and JT3C saw extensive use on fighter jetsjetliners, and bombers for many decades.
