Comparing: Bat.-Châtillon 25 t AP vs. AMX 30 1er prototype

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.

Developed as part of a competitive search for a unified European tank. The vehicle turned out to have maneuverability, engine power, and effective anti-tank engagement distance superior to all other vehicles except the Leopard 1. The armor of the vehicle was quite thin, but it was decided that technological advances in anti-tank shells had essentially rendered armor obsolete: survivability would depend on mobility and firepower.
