Historic:

The King Tiger, Germany's most formidable Heavy Tank, made its first appearance on the WWII theater in 1944. The first 50 tanks produced had Porsche turrets whereas subsequent tanks were equipped with the Henschel designed production turret. The King Tiger was armed with a 71-caliber 88mm gun that had enough power to penetrate 150mm thick armor from 2000m away. For protection, the chassis front armor was 150mm thick with 80mm thick side armor.

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.
