Comparing: Bat.-Châtillon 25 t AP vs. Lorraine 40 t

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.

A single prototype was manufactured in 1952. The vehicle featured suspension air-core tires and oscillating turret. The design passed trials but never entered mass production.
