The Mikoyan-Gurevich I-3 was the first of three interrelated fighter prototype programs developed by the Mikoyan-Gurevich design bureau in the Soviet Union in the mid/late 1950s – starting with the I-3, continuing with the I-7 and finally evolving into the I-75. On several occasions airframes were rebuilt and/or reused, both within a program or in a succeeding program. All the aircraft in the I-3 program were affected by delays in the development of the Klimov VK-3 afterburning bypass turbojet engine, and its cancellation and replacement by the Lyulka AL-7F turbojet engine.
