Jagdpanzer E 100

In 1943, work started on the Entwicklung series or E-series, a proposed line of German tanks that would use standardized components and designs to make production simpler and more affordable. Of these vehicles, the heaviest was the E 100, which the Adler firm began developing after it was proposed by Heinrich Ernst Kniepkampf. Little remains known about plans for the E 100; however, a partially built hull was seized by Allied forces in 1945. It has been suggested that the vehicle was to be modified to accommodate various large-caliber main guns.
