Vorne
The Vorne, or VK 4502 Ausf. A, is a tank designed by Ferdinand Porsche to compete with Henschel's design, alongside the Ausf. B version of the tank. The Henschel design was selected for production, but never reached the prototype phase. Porsche was confident that his design would win a contract for production and so he ordered Krupp to produce 50 turrets for the tank. These turrets were used on the first Tiger II's, which were supposed to be armed with a KwK L/71 gun, like its Henschel Counterpart.
Later, the Tiger II was upgraded with a better turret that had thicker armor and eliminated the shot trap. It was also more angular and therefore easier to produce.
