Comparing: Bat.-Châtillon 25 t AP vs. T 55A

In 1950–1951, engineers of the FAMH company (Compagnie des forges et aciéries de la marine et d'Homécourt) worked on the development of a medium tank with a 90-mm gun and a 25-ton rotating turret. Work was discontinued at the preliminary design stage. Later, all elements of the vehicle were incorporated in the Batignolles-Châtillon 25 t tank.

An upgraded version of the T-55 tank. The T 55A had a higher level of nuclear protection and no bow machinegun. From 1962 through 1970, about 1,800 of the T-55 and T 55A tanks were supplied to East Germany by the U.S.S.R.
