What is the world’s biggest gun?
Schwerer Gustav, also known as the “Heavy Gustav,” was the heaviest mobile artillery piece ever built. Moreover, the largest caliber rifled weapon ever on the field of combat.
A railway gun weighing nearly 1350 tons. In addition, boasting a firing capacity of 7-ton projectiles with a distance of up to 47 kilometers.
However her need of 500 men to man the gun, in addition to the 4,000 or so troops necessary to protect it, took away the tactical usefulness of the giant.
Originally developed in the late 1930s as siege artillery for the explicit purpose of destroying the main forts of the French Maginot Line. At the time the strongest fortifications in existence in the world.
