  History: The Landkreuzer P 1500 Monster ('monster') was a German self-propelled artillery pre-prototype designed during World War II, representing the pinnacle of extreme German tank and combat vehicle designs. On June 23, 1942, the German Ministry of Armaments proposed a 1,000-ton tank, the Landkreuzer P. 1000 Ratte. Adolf Hitler himself expressed interest in the project, for which he immediately received the go-ahead. In December of the same year, Krupp designed an even larger 1,500-ton tank, the P 1500 Monster, but in early 1943 Albert Speer, the Minister of Armaments, canceled the project. Possible design problems that led to its cancellation (along with the cancellation of the Ratte) were massive size (which would make it very easy to detect by Allied aircraft in the air and impossible to transport by rail), difficult to transport (because of its heavy would devastate highways and byways), the amount of material needed to manufacture it (Germany could not afford to use

  History: was a German 80-centimetre (31.5 in) railway gun. It was developed in the late 1930s by Krupp in Rügenwalde as siege artillery for the explicit purpose of destroying the main forts of the French Maginot Line, the strongest fortifications in existence at the time. The fully assembled gun weighed nearly 1,350 tonnes (1,490 short tons), and could fire shells weighing 7 t (7.7 short tons) to a range of 47 km (29 mi). The gun was designed in preparation for the Battle of France, but was not ready for action when that battle began, and in any case the Wehrmacht's Blitzkrieg offensive through Belgium rapidly outflanked and isolated the Maginot Line's static defences, which were then besieged with more conventional heavy guns until French capitulation. Gustav was later deployed in the Soviet Union during the Battle of Sevastopol, part of Operation Barbarossa, where, among other things, it destroyed a munitions depot located roughly 30 m below ground level. The gun was moved
