The document summarizes the Mikoyan Project 1.44, also known as the MiG MFI, which was a Soviet fifth-generation fighter aircraft developed in the late 20th century as a technology demonstrator. Key aspects of the design included stealth, supermaneuverability, and supercruise capabilities. The aircraft first flew in February 2000 after many delays due to lack of funding. It demonstrated speeds up to 600 km/h and a maximum height of 1,000 m during its short test program, which was ultimately cancelled with the aircraft's status becoming unknown.
