Who canceled the project for the Landkreuzer P. 1000 Ratte, which would have surpassed the Panzer VIII Maus as being the heaviest fully enclosed armoured fighting vehicle ever built?
Landkreuzer P. 1000 Ratte The "Landkreuzer" P. 1000 "Ratte" (English: "Land Cruiser P. 1000 "Rat"") was a design for a super-heavy tank for use by Nazi Germany during World War II, proposed by Krupp director Edward Grotte in June 1942, who had already named it ""Landkreuzer"". Submitted designs and drawings of the tank went under the names "OKH Auftrag Nr. 30404" and "E-30404/1", which were presented in December 1942. The tank was planned to be 1000 metric tonnes, being far heavier than the Panzer VIII "Maus", the heaviest tank ever built (weighing 188 tonnes). The project gained the approval of Adolf Hitler, who had expressed interest in the development of the tank, but was canceled by Minister of Armaments Albert Speer in early 1943.
Sd.Kfz. 8 The "Sonderkraftfahrzeug" 8 ("special motorized vehicle 8") was a German half-track that saw widespread use in World War II. Its main roles were as a prime mover for heavy towed guns such as the 21 cm Mörser 18, the 15 cm Kanone 18 and the 10.5 cm FlaK 38. Approximately 4,000 were produced between 1938 and 1945. It was used in every campaign fought by the Germans in World War II, notably the Invasion of Poland, the Battle of France, the Balkans Campaign, the Eastern Front, the North African Campaign, the Battle of Normandy and the Italian Campaign.
