Allison J33-A-35 is a historical centrifugal-flow turbojet variant. The National Museum of the United States Air Force identifies it as the J33-series engine used exclusively on the F-80C fighter, T-33A trainer, and Navy TV-2 trainer; Allison produced more than 6,600 from 1949 to 1955. Its normal thrust is 4,600 lb (20.461 kN, derived), rising to 5,400 lb (24.015 kN, derived) with water/alcohol injection. This exact variant remains separate from broader J33, aircraft, missile, and actor records.
