The Mikoyan Project 1.44/1.42 is a multirole fighter technology demonstrator developed by the Mikoyan design bureau. It was designed for the Soviet Union's MFI project for the I-90 program, the answer to the U.S.'s Advanced Tactical Fighter (ATF). The MFI was to incorporate many fifth-generation jet fighter features such as supermaneuverability, supercruise, and advanced avionics, as well as some degree of radar signature reduction.
