Development history
FCM built the 1A at its La Seyne shipyard in response to a 1916 requirement for a heavy breakthrough tank. Unusually for the time it carried its main gun in a fully rotating turret and had thick armour. Trials from late 1917 were encouraging, and the design was enlarged into the Char 2C, ten of which were completed after the war. The 1A itself remained a single prototype.
