In 1946, GE proposed to the Army Air Forces a new engine, more powerful and fuel efficient than its earlier J35, but within the same frame size. To provide higher pressure ratios, and overall better performance, GE chose an axial-flow compressor design. First tested in 1947, the J47 passed its 150-hour test in 1948, and went into production later in the same year. Production ended in 1956, with more than 35,000 J47s manufactured, making it the most mass-produced turbojet engine in history.

The J47 powered a wide variety of aircraft including the the North American B-45 Tornado bomber, Consolidated-Vultee B-36 bomber (boost power), Boeing B-47 Stratojet bomber, Martin XB-51 attack bomber, North American F-86 Sabre Jet fighter, North American FJ-2 Fury fighter, Republic XF-91 interceptor, Chase XC-123A transport, and Boeing KC-97 Stratotanker (boost power). This J47-GE-17 engine powered the North American F-86D Sabre Jet and the Italian Fiat F-86K.
