GE070 Tiger I E (early) Tiger I E (Early) (GE070) Tunisia & Kursk Version When the Tiger was introduced in 1942 it was a weapon un-equalled in performance and protection, there was little the Allies in the Tunisia or Russia could do to knock them out. It had its disadvantages (it was slow and a little unreliable to start with), but at the time its clear advantages outweighed these. Development The Tiger first underwent development when specifications for a new heavy tank were sent out to various manufacturers. It was to mount a gun that penetrated 100mm of armour at a 1500m and also be able to withstand return fire from similar weapons. Henschel developed the VK3601, but this design was to have a squeeze bore weapon, which had to be abandoned due to the lack of an adequate supply of tungsten for the ammunition.

The new prototype became the VK4501 (H), the (H) to distinguish it from the parallel development of Porsche VK4501 (P) (which later became the Ferdinand). The order to start the final design was issued on 26 May 1941. Henschel was to develop the chassis while Krupp developed the turret. Porsche"s version was also still under development and Krupp was also to provide the turret for this. Rheinmetall also developed a turret mounting the 7.5cm KwK L/70 gun (later to become famous as the Panther"s gun) but this was abandoned in favour of the 8.8cm mounts. Production of the Tiger IE began in July 1942. Production of the Porsche model was abandoned after problems with the engines and suspension and only five tanks were completed. The Henschel model now became the sole Tiger in production. The target was to produce 285 by 12 May 1943 in time for the summer offensive. The Production model Henschel Tiger IE had 100mm of front armour on both its hull and turret, 80mm on its rear and s
