Mikoyan-Gurevich I-211

The I-211, also called the MiG-9Ye, was a Soviet high-altitude fighter prototype of the Second World War. It descended from the I-210, itself a MiG-3 re-engined with a Shvetsov ASh-82 radial after production of the liquid-cooled Mikulin AM-35A was to be phased out, and it used the improved ASh-82F. Compared with the I-210 the bureau reworked the engine cowling, moved the cockpit 24.5 cm aft, put the oil cooler inside the fuselage and fitted a larger tail, and armed it with two 20 mm ShVAK cannon. It first flew on 24 February 1943 and reached 670 km/h, but manufacturer trials dragged on until early 1944, by which time no high-altitude fighter was wanted, so the project ended with a single aircraft built.
