Char B1 bis

Historical information

The Char B1 was a French heavy tank manufactured before World War II.

It was a specialised heavy break-through vehicle, originally conceived as a self-propelled gun with a 75 mm howitzer in the hull; later a 47 mm gun in a turret was added, to allow it to function also as a Char de Bataille, a "battle tank" fighting enemy armour, equipping the armoured divisions of the Infantry Arm. Starting in the early twenties, its development and production were repeatedly delayed, resulting in a vehicle that was both technologically complex and expensive, and already obsolescent when real mass-production of a derived version, the Char B1 "bis", started in the late thirties. Although a second uparmoured version, the Char B1 "ter", was developed, only two prototypes were built.

The Char B1 bis was an upgraded variant with thicker armour at 60 mm maximum (55 mm at the sides) and an APX4 turret with a longer-barrelled (L/32) 47 mm SA 35 gun, to give the tank a real anti-tank capacity. It was the main production type: from 8 April 1937 until June 1940 369 units were delivered out of a total order for 1144, with series numbers 201 to 569. Before the war manufacture was slow: only 129 had been delivered on 1 September 1939. The monthly delivery was still not more than fifteen in December; it peaked in March 1940 with 45.
