Object 263Tier 9, Tank destroyer

The development of a heavy tank destroyer on the basis of the IS-7 heavy tank was started in 1950. Three design projects were developed, one of which resulted in a full-size wooden prototype. However, further development was discontinued due to phasing out mass-production of the IS-7.
