Comparing: T-54 first prototype vs. M4A1 Revalorisé

Developed at Factory No. 183 in 1944. It was based on the T-44, with many components modified to enhance the armor and armament of the new vehicle. According to one source, the first prototype was built at the end of 1944. However, some other sources mention another date—January 1945. The tank underwent trials in March and April 1945, but never entered mass production.

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.
