The VK 30.01 (P) was the official designation for a medium tank prototype produced by Germany between 1940 and 1941. Two prototype hulls were made. The tank never entered serial production, but was further developed into the VK 4501 Tiger (P). The VK 3001 (P) was sometimes known, and referred to, as the Porsche Typ 100.[1][2]
Beginnings of the VK 30.01 (P)
In 1939, the German Army expressed the need for a 30 ton tank.[1] Projects to meet the demand were designated VK 30.xx (X)[lower-alpha 1] and were developed to varying degrees by four different companies: Porsche, Henschel & Son, MAN, and Daimler Benz. The Porsche version was thus named the VK 30.01 (P).[1][3]
Development
The requirements for the new development of a 30-ton schwere Panzerkampfwagen included the ability to mount at least the 7.5cm KwK L/24 main gun with a desire to fit the 10.5cm KwK L/28 if possible.[1][2][3] Later, in 1941, the German Army encountered unexpectedly-heavily armoured enemy vehicles such as the Soviet T-34 and KV-1. Plans were then made to instead mount the more effective 8.8cm KwK L/56.[2]
Krupp were directly contracted by Porsche to produce the turret to house the 8.8cm KwK L/56 and the two teams worked together to develop it for the VK 3001 (P) chassis. A fully developed drawing with the Krupp turret was completed, dated 5 March 1941.[2] The Krupp turret would go on to be used on both the Tiger (P) and the infamous Tiger I.
Uncommon for tanks at the time, Porsche selected a Gasoline-electric drive train.[1][2] The front drive sprockets for the tracks were driven by two electric motors mounted forward in the hull. Two, air-cooled, V-10 gasoline engines, mounted toward the rear of the vehicle, were each connected to a generator to produce electricity. The generated electricity was then used to power the motors.[2] Each engine produced 210hp at 2500 RPM; a total of 420hp was therefore available to drive the generators.[2]
Notes
- ↑ VK from the German Voll Ketten meaning fully tracked; 30 for the approx. weight of 30t; and the final 2 digits xx denoting 1st/2nd/3rd design from the respective manufacturer. The X in brackets denotes manufacturer.
