Comparing: T110E5 vs. (R) IS-7

Developed from 1952 as a heavy tank with more powerful armament, compared to the T-43 (M103). Restrictions were placed on the vehicle sizing as the tank was supposed to pass through the narrow tunnels of the Bernese Alps. Several designs were considered, but the project was canceled. No vehicles were ever manufactured.

Development of the IS-7 started in the spring of 1945. Prototypes successfully underwent trials in 1946 and 1947. However, the IS-7 never saw mass production.
