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 B. The ordnance inventory designation was Sd.Kfz. 182. It is also known under the informal name Königstiger (German for "Bengal tiger"), often mistranslated as King Tiger or Royal Tiger by Allied soldiers.
The Tiger II was the successor of the Tiger I, combining the latter's thick armor with the armor sloping used on the Panther medium tank. The tank weighed almost seventy metric tons, was protected by 100 to 180 mm (3.9 to 7.1 in) of armor to the front, and was armed with the long barreled 8.8 cm Kampfwagenkanone 43 L/71 gun. The chassis was also the basis for the Jagdtiger turretless tank destroyer.
