Comparing: Centurion Mk. I vs. STA-1

Development of the Centurion started in 1943. The vehicle was designed as a "universal tank" to replace existing infantry and cruiser tanks. The Centurion was the first British vehicle that featured sloped armor plates. The tank entered service in 1947. A total of 100 vehicles of this series were manufactured from 1945 through 1946.

The first Japanese post-war tank was developed on the basis of U.S. vehicles. The STA-1 was developed, taking into consideration Japanese terrain, rail network specifications, and anthropometric data of Japanese tankers. Only one prototype was built, in December 1956.
