Landkreuzer P. 1000 Ratte

"Next, there's the Landkreuzer P. 1000 Ratte. Despite being unfinished during World War II, Fegelein has a job to fulfill the wishes of using Nazi superweapons that were frozen in the drawing board back in the time when the whole world was still fighting against the Nazis for the first time, in the early 40s, in the battlefield, for such a full time."

--Su Ji-Hoon, The Fulfillment

The Landkreuzer P. 1000 "Ratte" (English: Land Cruiser P. 1000 "Rat") is 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," and for full usage by the Nazi Union during World War III. 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.

Fortunately, during the Third World War, it was finished by Hermann Fegelein and a team of Chinese, Russian, North Korean and North Japanese factory workers, including Wehrmacht soldiers, just like any other Wunderwaffen.
