Mikoyan-Gurevich MiG-15 Bis

The MiG-15 is a single seat Soviet fighter, designed after World War II as an interceptor and then adapted for the role of ground attack, reconnaissance or pilot training as a two seat variant.

Entering service with the Soviet Air Force in 1948, this aircraft was a formidable foe for the UN allies during the Korean War. Later, the type was used by the air forces of forty different countries around the world and became one of the most produced jet combat aircraft in history.

Prior to and during World War II, the Soviet Union lacked certain new aviation technologies. Towards the end of the conflict, Soviet forces captured many German designs, including the already operational Me-262 jet fighter, as well as other aircraft in prototype stage such as the Focke-Wulf Ta 183. The Soviet manufacturers were inspired by these aircraft for their new aerodynamic designs, and attempted to perfect the Junkers Jumo 004 and BMW 003 jets. But the first Soviet jet fighters were nevertheless inferior to their Western counterparts.

In April 1947, the Mikoyan-Gurevich design office acquired the new Klimov RD-45 jet engine, which was merely a copy of the Rolls Royce Nene. On the basis of German research that recognized the superiority of a swept wing design at high speeds, and the existing MiG-9, the engineers redesigned the project. Fitted with a wing swept back by 35°, the prototype made her first flight on the 30th of December 1947. In 1950, the MiG-15bis was fitted with an improved engine, the VK1, and certain airframes are adapted for ground attack purposes. The Soviet fighter was ready to face her Western opponents.
