Siege of Sevastopol, 1942, Karl-Gerät and Schwerer Gustav

 


⇒ “Karl-Gerät” (040/041) (German literally “Karl-device”), also known as Mörser Karl, was a World War II German self-propelled siege mortar (Mörser) designed and built by Rheinmetall. Its heaviest munition was a 60 cm (24 in) diameter, 2,170 kg (4,780 lb) shell, and the range for its lightest shell of 1,250 kg (2,760 lb) was just over 10 km (6.2 mi). Each gun had to be accompanied by a crane, a heavy transport trailer, and several modified tanks to carry shells.

Seven guns were built, six of which saw combat between 1941 and 1945. It was used in attacking the Soviet fortresses of Brest-Litovsk and Sevastopol, bombarded Polish resistance fighters in Warsaw, participated in the Battle of the Bulge, and was used to try to destroy the Ludendorff Bridge during the Battle of Remagen. One Karl-Gerät has survived and the remainder were scrapped after the war.

⇒ Schwerer Gustav (English: Heavy Gustaf) was the name of a German 80 cm (31.5 in.) railway gun. It was developed in the late 1930s by Krupp in Darłowo (then Rügenwalde) as siege artillery for the explicit purpose of destroying the main forts of the French Maginot Line, the strongest fortifications then in existence. The fully assembled gun weighed nearly 1,350 tonnes, and could fire shells weighing seven tonnes to a range of 47 kilometres (29 mi). The gun was designed in preparation for the Battle of France, but was not ready for action when the battle began, and in any case the Wehrmacht‘s Blitzkrieg offensive through Belgium rapidly outflanked and isolated the Maginot Line’s static defenses, eventually forcing the French to surrender and making their destruction unnecessary. Gustav was later employed in the Soviet Union at the siege of Sevastopol during Operation Barbarossa, where among other things, it destroyed a munitions depot buried in the bedrock under a bay. The gun was moved to Leningrad, and may have been intended to be used in the Warsaw Uprising like other German heavy siege pieces, but the rebellion was crushed before it could be prepared to fire. Gustav was destroyed by the Germans near the end of the war in 1945 to avoid capture by the Red Army.

It was the largest-calibre rifled weapon ever used in combat, the heaviest mobile artillery piece ever built in terms of overall weight, and fired the heaviest shells of any artillery piece. It is only surpassed in caliber by the unused British Mallet’s Mortar and the American Little David bomb-testing mortar (both 36 inch; 914 mm).
