Comparing: STA-1 vs. T25 Pilot Number 1

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.

Developed by the United States Army Ordnance Corps on the basis of the mass-produced T23 tank with a 90-mm gun and reinforced armor. After the creation of two prototypes, 40 other vehicles were manufactured.
