Schwerer Gustav or Hitler’s giant gun was a fearsome weapon of war.
A distinctive feature of artillery of the Second World War were cannons of every increasing size and caliber. One other such weapon was the 914 mm Little David, constructed for the American army. It was intended to be used for attacking Japanese bunkers at the end of WWII. This mortar was the biggest in the world, but it was also never used in combat. The Japanese surrendered before its deployment.
Schwerer Gustav was conceived prior to the beginning of WWII when Hitler demanded its construction as a precursor to the invasion of France. It was to aid the German Army in penetrating the Maginot Line. Its construction missed the invasion of France but it did take part in some actions throughout the war. After years of development and construction, the weapon’s impact on the war was very small in the greater scheme of things. As impressive as the weapon was its fate was far from honorable.
Schwerer Gustav shell was 800 mm or 80 cm in diameter. This baby was a railway gun developed by the Krupp family company who also developed the Big Bertha cannons in WWI.
It was designed in the 1930’s in order to destroy the strongest defensive facilities of their time – the Maginot Line in France. This defensive line was built by the French along the frontier with Germany and consisted of different obstacles, concrete bunkers and fortifications, and weapons installations. The desired specification was that the cannons should be able to destroy 1-meter thick layers of steel or 7-meter thick walls of reinforced concrete. Fate changed its plans when the war began. The Wehrmacht invaded France by passing through Belgium, thus circumventing the Maginot Line and conquering France without the necessity of destroying the defensive line.
According to Wikipedia, Schwerer Gustav weighed in at around 1350 tonnes and was capable of firing 4.8 metric ton heavy projectiles at a distance of 47 km with a muzzle velocity of 820 m/s. Schwerer Gustav damage was incredible! Although not used to fulfill their initial purpose, the Gustav super cannons were transported to the Eastern front and participated in the Fall Barbarossa (Operation Barbarossa in German). During this operation, the cannon was used for the siege of Sevastopol. After that, it was transported near Leningrad (now Saint Petersburg) and started preparation for the siege, but the operation was canceled. The gun was sadly later destroyed in order to avoid its capture.
