AMX Tracteur C Mle. 1939

While French firm FCM was developing the F1 superheavy tank, rival firm AMX was working on its own response to the French Army’s request for updated “fortress tank” designs: a design it called the Tracteur C. Unlike the FCM F1, the Tracteur C mounted its primary 105mm gun on the main turret toward the front and its secondary 47mm gun on the rear turret. The French Army selected the F1 for further development in December 1939, but AMX continued refining its design the following year.
