Tiger II is the common name of a German heavy tank of the Second World War. The final official German designation was Panzerkampfwagen Tiger Ausf. B, often shortened to Tiger II. The ordnance inventory designation was Sd.Kfz. 182. It is also known under the informal name Königstiger (the German name for the Bengal tiger), often translated literally as Royal Tiger, or somewhat incorrectly as King Tiger by Allied soldiers, especially by American forces. The Tiger II was the successor to the Tiger I, combining the latter's thick armour with the armour sloping used on the Panther medium tank. The tank weighed almost 70 tonnes, and was protected by 100 to 185 mm (3.9 to 7.3 in) of armour to the front. It was armed with the long barrelled 8.8 cm KwK 43 L/71 anti-tank cannon. The chassis was also the basis for the Jagdtiger turretless tank destroyer.
