Heavy Gustav

Leisure Projects

Heavy Gustav was named after the head of the Krupp family, the Gustav Gun weighed in at a massive 1344 tons, so heavy that even though it was attached to a rail car, it still had to be disassembled before moving so as to not destroy the twin set of tracks as it passed over. This 4-story (12 meters) behemoth stood 20 feet wide (7 meters) and 140 feet long (47 meters). Its 500 man crew, commanded by a Major-General, needed nearly three full days (54 hours, to be exact) to set it up and prep for firing. With a maximum elevation of 48 degrees, the Gustav shell could fire shells weighing seven tons to a range of 47 kilometers (29 miles). The caliber was 80 cm, and Gustav could fire 1 round every 30 to 45 minutes. The Gustav saw only very brief action. The siege of Sevastopol was the gun’s first combat test. Installation began in early May, and by June 5 the gun was ready to fire. It fired 300 shells on Sevastopol (at a rate of about 14 shells a day) and 30 more during the Warsaw Uprising of 1944 before being captured. On 14 April 1945, one day before the arrival of US troops, Schwerer Gustav was destroyed to prevent its capture. On 22 April 1945, its ruins were discovered in a forest 15 kilometres (9.3 mi) north of Auerbach and about 50 kilometers (31 mi) southwest of Chemnitz. In summer 1945 Schwerer Gustav was studied by Soviet specialists and in autumn of the same year was transferred to Merseburg, where the Soviets were gathering German military material. Thereafter, the trail of the gun was lost.
