The Tiger II was 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 was also known informally as the King Tiger.
Henschel won the design contract, and all Tiger IIs were produced by the firm. Two turret designs were used in production vehicles. The initial design is often misleadingly called the "Porsche" turret due to the misbelief that it was designed by Porsche for their Tiger II prototype; in fact it was the initial Krupp design for both prototypes.
