Comparing: KV-13 vs. T-34-1 vs. Type 5 Chi-Ri

Development was started in the fall of 1941, under the initiative of Semyon Ginsburg. After successful trials in the fall of 1942, the development of a second prototype was begun.

In 1954 the Chinese government considered the possibility of launching production of the T-34-85 in China. At the same time, Chinese engineers proposed an alternative project: the T-34-1. While based on the T-34-85, the T-34-1's transmission compartment and suspension were to be rearranged, reducing overall weight and giving a lower hull. In 1954, several designs of the vehicle, with varying turrets and armament, were developed. However, a prototype was never built.

A single prototype was manufactured at the beginning of 1945. The vehicle underwent trials and was recommended for service. However, Japan was defeated before mass production could begin. After the surrender, the prototype was confiscated by American occupation authorities and was shipped to the United States.
