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.
German tanks in World War II
Even larger and heavier than the Tiger I, the Pzkpfw VIB Tiger II. It is also known under the informal name Königstiger (the German name for the "Bengal tiger"), often semi-literally translated as the King Tiger or Royal Tiger by Allied soldiers. It was the largest tank mass-produced by German forces during the war, and remains among the heaviest mass-produced tanks ever. Its 8.8 cm KwK 43 could virtually knock out every Allied tank, while its sloped armor was thick enough to defeat most Allied guns (excluding hollow charge weapons). However, the Tiger II suffered from multiple mechanical problems due to its rushed development and excessive weight. It was named after the Tiger but it was a combination of innovations learned from the Panther and Tiger I.
