The first generation T-34 medium tank made its debut in combat during the summer of 1941, when the Wehrmacht launched its invasion of the Soviet Union. The T-34 easily outclassed the German PzKpfw III and IV models, thanks to its hard-hitting 76.2mm main gun, thick frontal armor, wide tracks, and overall superior mobility.

Early in 1943, orders were given to design a heavy, self-propelled anti-tank gun, which would mate a 12.8cm gun with a Tiger II chassis. On October 20th, 1943 a wooden mock-up of the enormous vehicle was shown to the OKH planners who authorized that a prototype be finished by April 1944.

The Elefant (Elephant) stemmed from the Porsche design for the PzKpfw VI Tiger. Henschel was awarded the contract for the new tank, but it was decided to use the Porsche design as a tank destroyer. Hitler demanded that the new vehicle be ready for the 1943 offensive on the Russian front, so development was rather hurried.
