The Panzerkampfwagen E-100 was a superheavy tank project developed by the nazi Germany during the second world war. The E-100 was part of the panzer E series, which was an attempt of the Germans to standardize the fabrication and assembling vehicle lines and replacing their actual tanks. The tank was designed by Adler company following the Wehrmacht requeriments. Its design started during 1942, and its assembly started in the middles of 1943. But due to the Allied advances in the war and the Germany's resourses lack, Hitler ordered to stop the Superheavy tank projects and the work on the E-100 continued with a low priority, with only 3 Adler employees working on it. The E-100 was never finished and the prototype was captured by the Brithis forces, sent to England to being studied and finally scrapped during 1950s. Source: Objaverse 1.0 / Sketchfab
