Comparing: Jagdpanzer E 100 vs. Jagdtiger vs. Ferdinand

The E 100 was conceived as the basis for a self-propelled gun, an antiaircraft vehicle, and a tank destroyer. However, development was never started.

Developed from 1942 through 1944, the heavy tank destroyer, with the chassis of the Tiger II heavy tank, became the heaviest mass-produced armored vehicle ever. According to various sources, 70–79 tank destroyers were manufactured from 1944 through 1945. The vehicles saw service in the 653rd and 512th Heavy Panzerjäger Battalions.

Developed on the basis of the Porsche Tiger, with a total of 90 vehicles produced in April and May 1943. They first saw combat in the Battle of Kursk (Operation Citadel).
