A full-scale wooden mock-up was part produced, but the project was terminated in favor of FCM F1 (a directly competing design, which proved to be superior).

ARL C was intended to be very long to meet the requirement to cross trenches up to 7 meters wide.

The development path of the ARL C was extremely complex, due to the existence of a number of parallel super-heavy tank projects with overlapping design goals, the specifications of which were regularly changed.

It had a proposed weight of 120 tons, consisted of two detachable modules, armor up to 120 mm thick and could be armed with either a gun or a flamethrower.

In 1940, the specifications of ARL's tank, now named as "Tracteur C" to keep the project secrecy for outsiders, were changed: the tank was designed to have two turrets, 47 mm gun on front and on new larger turret, a 90 mm gun.
