E-100
The E-100 was to be a superheavy combat tank like the Maus, developed from an enlarged Tiger II chassis. It was to be fitted with the same turret as the Maus, although plans are also existed for two further turret designs. Development and building of a prototype E-100 started in 1944 but was largely abandoned after Adolf Hitler ordered an end to the development of the Maus.
Only the chassis was finished. It was taken to the United Kingdom for evaluation purposes and eventually scrapped.
The turret of the tanks had three versions. One was a tiger II version, another was the Maus turret, the last one was the Krupp turret.The Maus turret housed 150 or 170 mm KwK gun + secondary 75 mm KwK gun . The Krupp turret housed the deadly 128 mm KwK gun + secondary 75 mm KwK gun. The Tiger-Maus Variant only had a 128 mm KwK 44 L/55 (75 rounds). Amour was 240mm-40mm.
Development drawings have been circulated for E-100 variants including an E-100 with a twin 55-mm anti-aircraft turret (Alligator) and a tank destroyer mounting a 152/170mm gun (Krokodil). Although the subject of models and much discussion, it is not clear whether these would have proceeded to production with the E-100 itself.
