It likely equipped ''Artillerie-Abteilungen 767'' and ''768'', which were the only ''Heer'' battalions to field 21 cm guns during the war. Some guns may have served on coastal defence duties.

Siege Gun
Siege artillery (also siege guns or siege cannons) are heavy guns designed to bombard fortifications, cities, and other fixed targets. They are distinct from field artillery and are a class of siege weapon capable of firing heavy cannonballs or shells that required enormous transport and logistical support to operate. They lacked mobility and thus were rarely useful in more mobile warfare situations, generally having been superseded by heavy howitzers (towed and self-propelled artillery), strategic bomber aircraft, surface-to-surface missiles, ballistic missiles, cruise missiles and multiple rocket launchers in modern warfare.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krupp
The Krupp family (see pronunciation), a prominent 400-year-old German dynasty from Essen, is notable for its production of steel, artillery, ammunition and other armaments. The family business, known as Friedrich Krupp AG (Friedrich Krupp AG Hoesch-Krupp after acquiring Hoesch AG in 1991 and lasting until 1999), was the largest company in Europe at the beginning of the 20th century, and was the premier weapons manufacturer for Germany in both world wars. Starting from the Thirty Years' War until the end of the Second World War, it produced battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities. The dynasty began in 1587 when trader Arndt Krupp moved to Essen and joined the merchants' guild. He bought and sold real estate, and became one of the city's richest men. His descendants produced small guns during the Thirty Years' War and eventually acquired fulling mills, coal mines and an iron forge. During the Napoleonic Wars, Friedrich Kr ...
