During the ATF program, one YF-23 was powered by twin Pratt and Whitney YF119 turbofan engines, while two General Electric YF120 turbofan engines were installed in the other prototype. Featuring a diamond-shaped planform, two large, sharply-canted ruddervators, and a serrated aft profile, the high performance aircraft was larger than the F-15 it was designed to replace. The YF-23 employed stealth characteristics and was capable of supersonic cruise flight without afterburner.
