The E-100 is infrequently referred to as the "Tiger III" and more commonly mistaken for the Maus super heavy tank. Not without good reason, considering that development of the E-100 and the Maus were concurrent and because the Maus progressed more quickly the E-100 was intended to have mounted an identical turret. This makes even technical illustrations of the two look surprisingly similar, but the E-100 was more than just a lousy Maus imposter. As the scale tipping end of Germany's rather ingenious "E-series" of next generation tanks the E-100 was planned to be the platform for a variety of super heavy armored vehicles. Among these was the E-100 "Krokodil", a super heavy anti-tank vehicle.

Without the Maus turret to contend with the Krokodil would have slimmed down the slightly ridiculous 3.6 meter profile of the turreted E-100 and lightened the load on the E-100's 800 horsepower Maybach engine. While the E-100 would have never lived up to its promised road speed of 40 kilometers per hour (twice as fast as the Maus!) the Krokodil would have likely come closer. The Krokodil would have maintained or even enhanced the E-100s already comical 24 centimeters of sloped armor. The most powerful anti-tank gun fielded by the Germans by the end of the war was the 128mm KwK 44 used by the Jagdtiger and planned for the Maus. The E-100 tank and Jagdpanzer Krokodil both would have mounted a 170mm anti-tank gun capable of driving an armor piercing shot through anything on the battlefield at ranges up to four kilometers.

The E-100 was projected to weigh a "mere" 136 tons, but this number hardly seems realistic given that the weight of the less heavily armed Maus was 188 tons. The E-100, like the Maus, also mounted a coaxial 75mm gun for anti-personnel duty. This gun would have been done away with in the purpose-built Krokodil and would have further trimmed the operational weight of the vehicle and freed up room for more ammunition. Sold Out!
