It is called the 800mm siege. It is a giant cannon that travels on giant railroads, and when the gun is fully assembled it weighed 1,350 tonnes and could fire shells weighing 7 tonnes as far as 47 kilometers ( Or 29 miles). A Krupp engineer, Erich Müller, calculated the task to penetrate the concrete would require a weapon with a caliber of 80 cm, firing a projectile weighing 7 tonnes from a barrel 30 meters long. The gun's shells had to punch through seven metres of reinforced concrete or one full metre of steel armour plate, from beyond the range of French artillery. This weapon was originally built for the Battle of France in the Great War, but by the time the battle came, the weapon was not fully assembled. This giant cannon is the largest caliber rifled weapon that was ever used in combat, it is the heaviest mobile artillery piece ever built in terms of weight, and fired the heaviest shells of any artillery piece. It is only surpassed by the British Mallet’s Mortar and the American Little David (both 36 inches; 914 mm) which neither ever used in combat. This operation stopped because it became to expensive to build new railroads for the
