Panzer VIII Maus
Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed before the testing grounds were captured by advancing Soviet military forces.
Char G1
"Baudet-Donon-Roussel" proposed to build a tank with the general outlines of the Char B1, including a high return track run, but with seven road wheels per side that unlike the B1 did not require a daily greasing, instead using sealed ball-bearings. The track was to have a continuous rubber (Pendelastic) inner lining. The project was to have the following dimensions: a length of 556 cm; a width of 280 cm and a height of 285 cm. It thus was the largest and heaviest of all proposals with a weight of 28,5 tonnes. Track width was to be 35 cm. The normal wading capacity was to be 145 cm; BDR thought it also possible to make the tank fully immersible to cross rivers while being guided from the river bank. It was planned to install an air-cooled Potez 12V 320 hp engine, placed transversely in the hull. The transmission was petro-electrical and of the Gebus-Roussin type. The fuel tank was to have a capacity of 520 litres. The armament was to consist of a 75 mm SA35 howitzer in the hull with 70 rounds. In the 1937 configuration, the tank was to have an APX4 turret with a 47 mm SA35 gun with 102 rounds. As the hull was wide enough to place the 75 mm gun in its middle, the turret should have been moved to the left, but this was forgotten in the proposal, as the commission pointed out.
