E-100 Tiger-Maus

By Christian Ankerstjerne


In September 1942, while the Maus super-heavy tanks was being designed by Porsche, Krupp decided to submit a competitive design. It was suggested to use components from the Tiger II chassis, including the Maybach HL 230 engine, for a 150 ton tank. The turret was planned to be the same as that of the Maus.


While the use of already existing components made Krupp's Tiger-Maus more feasible, the Maybach HL 230 meant that it was significantly underpowered. As a result, Krupp's design developed as a somewhat lighter vehicle, at 130 tons, compared to the Maus' then-projected weight of 170 tons. The reduced weight gave additional advantages of superior speed, ground pressure, and fuel consumption, as well as decrease raw material usage. In addition, a supercharged version of the HL 230 was considered, which would have an output of 1000 horse powers. Nevertheless, Hitler favored the more technically complex Maus. As a result, on 15 December 1942, Krupp was informed that the Tiger-Maus should cease, and on 5 January 1943, the Maus was chosen for production.

After the Maus had been chosen for production, Waffenamt Prüfwesen 6 (Weapons Testing Office 6, the office responsible for armor design) copied Krupp's Tiger-Maus for their E-100 design. Adler, who had no prior experience in armor design, was awarded the contract for a single E-100 prototype during 1943. Krupp designed a new turret in 1944, closely resembling the Maus turret, the only difference being somewhat thinner armor. As the war situation deteriorated, work on the E-100 stopped. By the time the war ended, an only partially assembled E-100 chassis was found by Allied forces.
