Comparing: E 100 vs. STA-2

In June 1943, the Adlerwerke company received an order for development of the E 100. However, in 1944, heavy tank development was discontinued. By the end of the war, only the chassis was completed, which was later captured by the British Army.

One of the first Japanese post-war tanks was developed on the basis of U.S. vehicles, taking into consideration Japanese terrain, rail network specifications, and the smaller stature of Japanese tankers. This variant prototype featured a shortened suspension and a larger hull height. A total of two prototypes were built.
