The General Electric J73 turbojet was developed by General Electric from the earlier J47 engine. Its original USAF designation was J47-21, but the innovative features (variable inlet guide vanes, and single-shell combustor case) led to its redesignation as J73. The J73 featured a compressor scaled down from the J53 developmental prototype to fit the J47 frame size; the J53 was a much larger type intended for use in early cruise missiles but never put in to production.
