The Mikoyan Project 1.44/1.42 (Russian: Микоян МиГ-1.44; NATO reporting name: Flatpack) was a technology demonstrator developed by the Mikoyan design bureau. It was the Soviet Union's answer to the U.S.'s Advanced Tactical Fighter (ATF), incorporating many fifth-generation jet fighter aspects such as advanced avionics, stealth technology, supermaneuverability, and supercruise. The design’s development was a protracted one, characterized by repeated and lengthy postponements due to a chronic lack of funds; the MiG 1.44 made its maiden flight in February 2000, nine years behind schedule, and was cancelled later that year.
