The French tier 9 medium tank Bat.-Chatillon 25t AP which was spotted on the supertest seems to be a potential replacement for the Lorraine 40t. This information is provisional.
In 1950-51 the engineers of FAMH were developing a medium tank project with a 90mm gun and a 25 ton hinged turret. All work was stopped during preliminary design phase and the results used to create the Batignolles-Chatillon 25t.
