Mikoyan-Gurevich I-220

The I-220, called Samolyot A inside the bureau, was a Soviet high-altitude fighter prototype of the Second World War, ordered in late 1942 to counter German high-altitude reconnaissance aircraft such as the Ju 86R. It was an entirely new design of mostly wood veneer construction with a steel-tube engine mount, a laminar-flow wing, slats and split flaps, and four ShVAK cannon. Its development grew into the I-221, I-222, I-224 and I-225, which added turbo-superchargers, pressurized cockpits and different Mikulin engines, and seven prototypes were built across the five versions. The I-222 had the best ceiling of any Allied piston fighter, but by 1944 the threat had faded and no production was ordered, though the MiG-7 and MiG-11 names were reserved.
