The '''Krupp Landkreuzer P-1000 Ratte''' was a proposed German main battle tank in 1942 which, if actually built, would have been the largest tank ever placed in the field. Its extreme size and the estimated cost of production during [[World War II]] led to the project's cancellation in 1943. | The '''Krupp Landkreuzer P-1000 Ratte''' was a proposed German main battle tank in 1942 which, if actually built, would have been the largest tank ever placed in the field.
