The Landkreuzer P 1500 Monster was a German pre-prototype super-heavy artillery designed during World War II, representing the apex of the German extreme artillery designs.

Conception

On 23 June 1942 the German Ministry of Armaments proposed a 1,000 tonne tank—the Landkreuzer P. 1000 Ratte. Adolf Hitler himself expressed interest in the project and go-ahead was granted. In December the same year, Krupp designed an even larger 1,500 tonne vehicle—the P. 1500 Monster.

In 1943, Albert Speer, the Minister for Armaments, canceled both projects.

Purpose

An 800 mm shell that would have been used, next to a T-34/85

This "land cruiser" was a self-propelled platform for the 800mm Schwerer Gustav artillery piece also made by Krupp—the largest artillery guns ever fired for effect. Their 7-tonne projectiles fired up to 37 km (23 mi) and were designed for use against heavily fortified targets.

Specification

The Landkreuzer P. 1500 Monster was to be 42 m (138 ft) long, weighing 1500 tonnes, with a 250 mm hull front armor, four MAN U-boat (submarine) marine diesel engines, and an operating crew of over 100 men.

The main armament was to be an 800 mm Dora/Schwerer Gustav K (E) railway gun, and with a secondary armament of two 150 mm sFH 18/1 L/30 howitzers and multiple 15 mm MG 151/15 autocannons. The main armament could have been mounted without a rotating turret, making the vehicle a self-propelled gun rather than a tank. Such a configuration would have allowed the P. 1500 to operate in a similar manner to the original 800mm railroad gun and Karl 600mm self-propelled mortars, launching shells without engaging the enemy with direct fire.

Issues

Development of the Panzer VIII Maus had highlighted significant problems associated with very large vehicles, such as their destruction of roads/rails, their inability to use bridges and the difficulty of strategic transportation by road or rail. The bigger the vehicle, the bigger these problems became, to the point where they were insurmountable.

Propulsion had also proved problematic in the development of the Maus: The prototype had failed to meet its specified speed requirements which meant that even larger vehicles such as the P. 1500 were likely to be slow-moving and, due to its massive size, it would be a major target to Allied aircraft.
