History of creation and combat usage

Ideas of rearming the Tiger II from its original 88 mm cannon was brought up by Krupp in sometime in late 1944. The concept drawing Krupp made was for the Tiger II to be rearmed with a 10.5 cm KwK L/68 cannon. This design would require new mountings and new mechanical parts to be optimized for the larger 10.5 cm gun. While the idea was indeed a very interesting one to up gun the Tiger II, it was never implemented because of its draw backs. The 10.5 gun would use a two-piece ammunition, which requires the presence of another loader. This is impossible because the turret is already cramped as is with three people inside, and the addition of another will make the interior a very miserable place to be in. Plus, the fact the gun's ammunition is two-piece already means that the drawback behind this upgrade is a much slower fire rate. This causes the concept to be rejected by German high command, and if it wasn't, it certainly ended with Germany's surrender in May 1945.
