Land Cruiser Ratte was a concept of superheavy tank to be used by Germany during World War II which have been proposed in June 1942.

The tank was planned to be 1000 tons, far heavier than any other tank of that or other time. The project was cancelled in early 1943. as unrealistic.

Land Cruiser should consist of a fully tracked chassis carrying one of the surplus main gun turrets left over from the planned refitting of the battleships.

To protect this immense vehicle, the hull of the mega tank was to carry armor up to 25 centimeters thick, and several anti-aircraft guns were to be installed on the vehicle's engine deck to fend off Allied ground-attack aircraft.

Planned propulsion was by two marine diesel engines from submarines.

The Ratte′s primary weapon would have been a dual 28 cm naval gun turret but with the center gun and its associated loading mechanism removed.

The tank was to be provided with a vehicle bay that could hold two motorcycles for scouting, and several smaller storage rooms, a compact infirmary area, and a self-contained lavatory system.
