Comparing: 110 vs. O-Ho

From the mid-1940s to the 1950s, Soviet engineers attempted to modernize the IS-2 tank. The IS-2U variant, developed in November 1944, was conceived to have a reinforced frontal hull with a plate configuration resembling that of the IS-3. In the mid-1950s the design project was passed to China and became the basis of further Chinese tank development.

The O-Ho was a further development of the idea of a superheavy tank with improved armor protection. The vehicle had a good set of guns that allowed for all-angle fire. The project was discontinued due to the war ending. No finished prototypes were built and the vehicle never saw action.
