Comparing: T-54 vs. Type 61

The first prototype was constructed at the end of 1944. After successful trials in 1945–1947 the T-54 mod. 1947 was adopted for service. 713 vehicles were constructed before production was phased out. In 1949 production of a new variant was launched.

The first tank developed in Japan after WWII. It was developed from 1954 through 1961 on the basis of the American M47 tank. The dimensions of the vehicle were decreased and the armor was reduced. As a result, the weight of the tank was lighter, and the tank complied with the requirements of the Japanese armed forces.
