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.
T-28 The T-28 was a Soviet multi-turreted medium tank. The prototype was completed in 1931, and production began in late 1932. It was an infantry support tank intended to break through fortified defences. The T-28 was designed to complement the heavier T-35 (also multi-turreted), with which it shared turret designs. The type did not have great success in combat, but it played an important role as a development project for Soviet tank designers. A series of new ideas and solutions that were tried out on the T-28 were later incorporated in future models.
