The Mikoyan-Gurevich I-75 was the final design of a series of three experimental swept-wing interceptors developed in the Soviet Union in the mid-late 1950s by the Mikoyan-Gurevich design bureau from their Mikoyan-Gurevich I-3 airframe. All the aircraft in the I-3 program were affected by delays in the development of the Klimov VK-3 turbojet engine, its cancellation and ultimate replacement by the Lyulka AL-7F turbojet engine.
