Mikoyan-Gurevich DIS

The DIS, short for the Russian words for long-range escort fighter, was a twin-engined, twin-tailed Soviet heavy fighter prototype of the Second World War, ordered in October 1940 from the design office that became the Mikoyan-Gurevich bureau. The service name MiG-5 was reserved for its production version. It had a mixed duralumin, wood and steel-tube structure, a pair of Mikulin AM-37 inline engines under the wing, a heavy cannon pod under the nose and room for bombs or a torpedo. The first prototype flew on 11 June 1941 but was well short of its estimated speed, and the second prototype, flown on 28 January 1943 with Shvetsov M-82 radial engines, performed only moderately. The project was cancelled in October 1943.
