General Electric YF120

Common card · No. 473741

The General Electric YF120, internally designated as GE37, is a variable-cycle afterburning turbofan engine designed by General Electric Aircraft Engines in the late 1980s and early 1990s for the United States Air Force's Advanced Tactical Fighter (ATF) program. It was designed to produce maximum thrust in the 35,000 lbf (156 kN) class. Prototype engines were installed in the two competing technology demonstrator aircraft, the Lockheed YF-22 and Northrop YF-23. While the F120 design more ambitious due to its variable cycle architecture, the Pratt & Whitney's competing F119 was deemed less expensive and risky, and was selected over the F120 to power the ATF, the competition for which the Lockheed team won and became F-22 Raptor.
