The Tiger II unofficially known as the King Tiger developed in 1943 was produced by Henschel from 1944 onwards The King Tiger combined the requirements for armoured protection & fire power in an exemplary manner The front armour up to 150 mm thick could not be penetrated by any of the on-board weapons of its opponents The side armour was up to 80 mm thick Despite several massive allied bombardments of the Henschel works in Kassel a total of 492 Tiger IIs
- including the prototypes & 50 vehicles equipped with the Porsche turret
- were delivered to the troops However not all of these reached the units at the front A large number of Tiger IIs were lost when they broke down as a result of their heavy overall weight or simply because they ran out of fuel
