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.
History of the tank
The Tsar Tank, also known as the Lebedenko tank after its designer – was a tricycle design vehicle on 9 m high front wheels. It was expected that such large wheels would be able to cross any obstacle but because of a flawed design most of the weight was forced through the smaller rear wheel, which became stuck when tested in 1915. The designers were prepared to fit larger engines but the project – and the vehicle – was abandoned.
