This tank was designed in March-August 1949 at OKB IK SV (Special Design Bureau of Engineering Committee of Ground Forces) under the direction of A.F. Kravtsev. As per the design, the tank was planned to feature the driver's seat in the fighting compartment, a 100 mm gun with an autoloader, and a large-caliber coaxial machine gun. The power unit was represented by a 12-cylinder opposed turbo diesel engine. Ski-shaped mountings were to perform the task of support rollers. The K-91 design did not move past the draft stage, and its development stopped in December 1949.
