Comparing: M4A1 Revalorisé vs. STA-1

In the 1950s, the M4 Sherman of various modifications was supplied to France as part of MDAP. French design bureaus started modernizing the vehicle with the goal of improving its firepower. This initiative was followed by a modernization program for the Israel Defense Forces (Sherman M51). The tank never saw service in France. The number of prototypes built is unknown.

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.
