1:1 scaled build of the ratte tank from the Third Reich.
History:
The development history of the Ratte originated with a 1941 strategic study of Soviet heavy tanks conducted by Krupp, the study also giving birth to the Panzer VIII Maus super-heavy tank. The study led to a suggestion from Krupp director Grote, special officer for submarine construction, who on June 23, 1942 proposed to Hitler a 1,000-tonne tank which he named a Landkreuzer. It was to be armed with naval artillery and armored with 10 inches (25 cm) of hardened steel, so heavily that only similar weapons could hope to affect it. To compensate for its immense weight, the Ratte would have been equipped with three 1.2 metre (3.9 ft) wide treads on each side with a total tread width of 7.2 metres (24 ft). This would help stability and weight distribution, but the vehicle's sheer mass would have destroyed roads and rendered bridge crossings completely impractical. However, it was anticipated that its height, and its ground clearance of 2 metres (6.6 ft) would have allowed it to ford most rivers with ease.
Hitler became enamored with Grote's concept and ordered Krupp to begin development on it in 1942. As of December 29, 1942 a few preliminary drawings had been completed, by which time the concept had been named Ratte (Rat). Albert Speer canceled the project in 1943 before any were actually constructed.
Propulsion
The Ratte was to be propelled by two MAN V12Z32/44 24 cylinder marine diesel engines of 8,500 hp (6.2 MW) each (as used in U-boats) or eight Daimler-Benz MB 501 20 cylinder marine diesel engines of 2,000 hp (1.5 MW) each (as used in E-boats) to achieve the 16,000 hp (11.8 MW) needed to move this tank. The engines were to be provided with snorkels also like those used by German submarines. The snorkels were of course designed to provide a way for oxygen to reach the engine, even during amphibious operations passing through deep water.
Armament
The Ratte's primary weapon would have been a dual 280 mm SK C/28 gun turret. The turret was to have been a modified Kriegsmarine triple gun turret, removing one of the guns and loading mechanism.
Further armament was to consist of a 128 mm anti-tank gun of the type used in the Jagdtiger or Maus, two 15 mm Mauser MG 151/15 autocannons, and eight 20 mm Flak 38 anti-aircraft guns, probably with at least four of them as a quad mount. The 128 mm anti-tank gun's precise location on the Ratte is a point of contention among historians, most believing that it would have been mounted within the primary turret, with some others thinking a smaller secondary turret at the rear of the Ratte more logical. Some concept drawings exist to suggest a flexible mount on the glacis plate. The tank was to be provided with a vehicle bay sufficient to hold two BMW R12 motorcycles for scouting, two kubelwagen-jeeps and/or two light tanks. as well as several smaller storage rooms, a compact infirmary area, and a self-contained lavatory system.

1. The gun would be to innacurate to hit something even at close range (The JagdTiger had the same problem)
2.With the size and lack of speed in this tank, it would be forced to hit long distance targets
