The Tiger I heavy tank was arguably the most infamous tank of World War II. The design for this tank began as early as January 1937 when Henschel & Sohn worked on a large "breakthrough" called the "Durchbruchwagen" that weighed about 30 tons on request by the German military.^[1] The request was modified over time for more armour and better gun that increased the weight to 36 tons, but this project was dropped in 1938 in favour of the better prototypes VK 30.01(H) and VK 36.01(H). These new prototypes were the start of the usage of the Schachtellaufwerk wheel arrangements, but these also never passed prototype stages and were both cancelled in 1942.

During the development of the prototypes above, the German invasion of France showed that the Allied tanks such as the Somua, Char B1, and Matilda II were impervious to their current anti-tank weaponry and a need for better armoured and armed tanks was emphasized. So on May 26, 1941, Henschel and Porsche were asked to submit designs for a 45-ton heavy tank that was to be ready for demonstration by June 1942. During their development in June 1941, Germany initiated Operation Barbarossa against the Soviet Union and was shocked by appearance of the T-34 and KV-1 tanks that were invulnerable to all but the most potent anti-tank weapon in German inventory, one of which was the 88 mm KwK36 cannon. The potency of the 88 mm cannon against the heavily armoured tanks that the Germans faced had Hitler ordered that the heavy tank design undertaken by Henschel and Porsche to utilize the 88 mm as its main armament instead of a 75 mm cannon.

The designs of the tank were finalized and ready for demonstration on April 20, 1942, Hitler's birthday, and showed the VK 45.01(H) and the VK 45.01 (P). The demonstration and subsequent evaluations on the two designs determined that the Henschel variant was superior to the Porsche variant, proving more reliable, more mobile, and more easily produced than the Porsche. This caused the Henschel variant to be adopted as the Panzerkampfwagen VI Tiger and production started in August 1942. The Porsche variant had many chassis produced as Ferdinand Porsche thought the design would win, so the chassis was instead used in the Ferdinand tank destroyer.
