The St-Chamond tank

The St-Chamond tank

An official counter foot on the initiative of Colonel Estienne, this tank also bears the name of its constructor. Better armed - a long barrel of 75 mm - and a much more sophisticated mechanical design, it had to be much superior to its "competitor". A thermal engine supplied a generator which, in turn, supplied power to two electric motors, one per crawler. The differential power supply made it possible to control the machine. An astute but complex system that will cause many setbacks in operations.
