Landkreuzer P. 1500 Monster
In 1942 Hitler approved the design and construction of an extremely large tank, but the project was cancelled in 1943 before any actual construction had begun. The tank was supposed to be more than fifteen times as big as a normal tank and it should have been armed with a 800 mm Krupp cannon (the main cannon on a normal tank like the M1 Abrams is 105 mm).
The 800 mm Krupp cannon is the largest artillery weapon ever built. Each projectile weighted 7 tons and it could be fired up to 37 km (23 miles). I haven’t seen any pictures of the Landkreuzer P. 1500 Monster, so you must make do with a picture of the Krupp cannon (check out the soldier in front of the cannon).
