Entwicklung Series (Standard Series)


The E-Series program was conceived by Dipl Ing Heinrich Ernst Kniekamp, Chief Engineer of Waffenpruefamt 6 in May of 1942. In April of 1943, Heereswaffenamt (Army Weapons Office) accepted his program and ordered many different manufacturers to start the planning and development of the Entwicklung (project/development) / Einheitsfahrgestell (general purpose chassis) Series. It was designed in order to replace existing armored vehicles and tanks that were used by the German Army from 1945 onwards. All six basic designs of E-Series would have standardized parts making their production faster and cheaper and maintenance easier. In late 1944, Adolf Hitler cancelled any further development of the super heavy tanks and unfinished E-100 was virtually abandoned with very little work still being done as late as April of 1945.  The end of the war ended the development of the E-Series, which was in various stages ranging from blueprints to prototypes.  The development of the E-Series as seen from the projects developed by various makers was focused on Jagdpanzers and Waffentragers.  This was a direct response to the superior numbers of Allied armor on both fronts as of 1944 and need for mobile anti-tank and field artillery.  In mid 1944, overall capability of the German armaments industry was not in a position to supply the demands of the army, thus making any possibility of E-Series being in production in 1945 unrealistic.
