The Treaty of Versailles created, at best, a tenuous truce. Hoping to ward off another assault, France erected a seemingly impregnable network of forts along the German frontier. Determined to overcome this obstacle, Adolf Hitler issued orders that specified "a gun able to pierce a meter of steel, seven meters of concrete, or thirty meters of dense earth."
Krupp quickly complied, presenting Hitler the Gustav Gun—named in honor of family patriarch Gustav Krupp von Bohlen und Halbach. The biggest gun ever built, it weighed a crushing 1344 tons, including its railway carriage. With its breech block, the entire machine stood 4 stories tall, 20 ft. wide and 140 ft. long. Moving, positioning, loading and maintaining this monster required a 500-man crew commanded by a major general.
The Gustav's 800mm bore accepted two giant projectiles: a 10,584-pound high-explosive shell and a 16,540-pound concrete-piercing shell. Though it didn't deliver the range of the Paris Gun, the Gustav could strike targets up to 29 miles away.
As often happens in war, the original mission evaporated when German troops outflanked the Maginot line, quickly forcing France to surrender. Plans to use the Gustav against the British at Gibraltar were also scrapped, but eventually Gustav found a suitable target.
In April 1942, the Soviet city of Sevastopol fell under assault. One shot inadvertently destroyed a Russian ammo dump hidden 100 ft. below the Sevemaya military base. In quick succession, the gun crumbled the forts that were vainly defending the city.
In all, the Gustav fired 300 shells on Sevastopol, and another 30 during the 1944 Warsaw Uprising. It was never used again. Unlike the mysterious Paris Gun, the gun met a final—if ignoble—end. It was captured by U.S. troops and cut up for scrap. A duplicate gun, named for the chief engineer's wife, Dora, saw action only briefly and was destroyed to prevent its capture by the Russian army.
