Comparing: Panzer 58 Mutz vs. STA-1

Developed in 1953 in Switzerland, the first prototype of this tank featured a 90 mm gun. A second prototype with a British 20-pounder gun was built later. In the end, a series of 10 vehicles, featuring 105 mm guns, were produced and remained in service until 1964. After this, the vehicles were used as a basis for the Panzer 61. The only Panzer 58 that survives today features a 20-pounder gun and is currently located in the tank museum in Thun, Bern.

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.
