Notes: Two designs actually had this designation. The first one in 1945 only reached the wooden mockup stage. The second had it's first prototype completed 8 September 1946, followed by a second on 25 December 1946. This version had the 130mm S-26 gun.
Tests with 88mm, 122mm, and 128mm guns were carried out; and the hull and turret were redesigned for better armor protection. Additionally, the newer 130mm S-70 gun was fitted. Four of these improved IS-7s were built in the summer of 1948 and tested.
