In the 1930s, Krupp developed two 800 mm railway guns, the Schwerer Gustav and the Dora. These guns were the biggest artillery pieces ever fielded by an army during wartime, and weighed almost 1,344 tons. They could fire a 7-ton shell over a distance of 37 kilometers. More crucial to the operations of the German military was Krupp's development of the famed 88 mm anti-aircraft cannon which found use as a notoriously effective anti-tank gun.
