Franco-Prussian War The unexpected
victory of Prussia over France (19 July 187010 May 1871) demonstrated the superiority of
breech-loaded steel cannon over
muzzle-loaded brass. Krupp artillery was a significant factor at the battles of
Wissembourg and
Gravelotte, and was used during the siege of Paris. Krupp's
anti-balloon guns were the first
anti-aircraft guns. Prussia fortified the major North German ports with batteries that could hit French ships from a distance of , inhibiting invasion.
Venezuela Crisis Krupp's construction of the
Great Venezuela Railway from 1888 to 1894 raised Venezuelan national debt. Venezuela's suspension of debt payments in 1901 led to
gunboat diplomacy of the
Venezuela Crisis of 1902–1903.
Balkan Wars Russia and the Ottoman Empire both bought large quantities of Krupp guns. By 1887, Russia had bought 3,096 Krupp guns, while the Ottomans bought 2,773 Krupp guns. By the start of the
Balkan Wars the largest export market for Krupp worldwide was Turkey, which purchased 3,943 Krupp guns of various types between 1854 and 1912. The customer in the Balkans was Romania, which purchased 1,450 guns in the same period, while Bulgaria purchased 517 pieces, Greece 356, Austria-Hungary 298, Montenegro 25, and Serbia just 6 guns.
World War I Krupp produced most of the artillery of the Imperial German Army, including its heavy siege guns: the 1914 420 mm
Big Bertha, the 1916
Langer Max, and the seven
Paris Guns in 1917 and 1918. In addition,
Friedrich Krupp Germaniawerft built German warships and submarines in Kiel. During the war, Krupp also modified the design of an existing
Langer Max gun, which they built in
Koekelare. The gun called
Batterie Pommern was the largest gun in the world in 1917 and was able to shoot shells of ±750 kg from
Koekelare to
Dunkirk. Before World War I Krupp had a contract with the British armaments company Vickers and Son Ltd. (formerly Vickers Maxim) to supply Vickers-constructed Maxim machine guns. Conversely, from 1902 Krupp was contracted by Vickers to supply its patented fuses to Vickers bullets. It is known that wounded and deceased German soldiers were found to have spent Vickers bullets with the German inscription "Krupps patent zünder [fuses]" lying around their bodies.
World War II Krupp received its first order for 135
Panzer I tanks in 1933, and during World War II made
tanks, artillery, naval guns, armor plate, munitions and other armaments for the German military.
Friedrich Krupp Germaniawerft shipyard launched the
cruiser Prinz Eugen, as well as many of Germany's
U-boats (130 between 1934 and 1945) using preassembled parts supplied by other Krupp factories in a process similar to the construction of the US
liberty ships. In the 1930s, Krupp developed two 800 mm
railway guns, the
Schwerer Gustav and the
Dora. These guns were the biggest artillery pieces ever fielded by an army during wartime, and weighed almost 1,344 tons. They could fire a 7-ton shell over a distance of 37 kilometers. More crucial to the operations of the German military was Krupp's development of the famed
88 mm anti-aircraft cannon which found use as a notoriously effective anti-tank gun. In an address to the
Hitler Youth,
Adolf Hitler stated "In our eyes, the German boy of the future must be slim and slender, as fast as a greyhound, tough as leather and hard as Krupp steel" (
"... der deutsche Junge der Zukunft muß schlank und rank sein, flink wie Windhunde, zäh wie Leder und hart wie Kruppstahl.") During the war Germany's industry was heavily bombed. The Germans built large-scale night-time decoys like the
Krupp decoy site (German: Kruppsche Nachtscheinanlage) which was a German decoy-site of the
Krupp steel works in
Essen. During World War II, it was designed to divert Allied
airstrikes from the actual production site of the arms factory. Krupp Industries employed workers conscripted by the Nazi regime from across Europe. These workers were initially paid, but as Nazi fortunes declined
they were kept as slave workers. They were abused, beaten, and starved by the thousands, as detailed in the book
The Arms of Krupp. Nazi Germany kept two million French POWs captured in 1940 as forced laborers throughout the war. They added compulsory (and volunteer) workers from occupied nations, especially in metal factories. The shortage of volunteers led the Vichy government of France to deport workers to Germany, where they constituted 15% of the labor force by August 1944. The largest number worked in the giant Krupp steel works in
Essen. Low pay, long hours, frequent bombings, and crowded air raid shelters added to the unpleasantness of poor housing, inadequate heating, limited food, and poor medical care, all compounded by harsh Nazi discipline. In an affidavit provided at the Nuremberg Trials following the war, Dr. Wilhelm Jaeger, the senior doctor for the Krupp slaves, wrote: The survivors finally returned home in the summer of 1945 after their liberation by the allied armies. Krupp industries was
prosecuted after the end of war for its support to the
Nazi regime and use of forced labour.
Post–World War II Krupp's trucks were once again produced after the war, but so as to minimize the negative wartime connotations of the Krupp name they were sold as "
Südwerke" trucks from 1946 until 1954, when the Krupp name was considered rehabilitated.
The Mustang Krupp also used the name "Mustang" for some of their products, causing a problem for Ford Motor Company in 1964 when they desired to export their car of the same name to Germany, especially since American military personnel stationed there wanted the new car. Although Krupp offered to sell the Mustang name to Ford for a reasonable price, Ford declined and as a result, badged all Mustangs destined for Germany "T-5." By 1978 Krupp's rights to the Mustang name expired and all Mustangs exported to Germany henceforth retained the Mustang name.
Other accomplishments Krupp Steel Works of Essen, Germany, manufactured the spherical pressure chamber of the dive vessel
Trieste, the first vessel to take humans to the
deepest known point in the oceans, accomplished in 1960. This was a heavy duty replacement for the original pressure sphere (made in Italy by Acciaierie Terni) and was manufactured in three finely machined sections: an equatorial ring and two hemispherical caps. The sphere weighed 13 tonnes in air (net displacement eight tonnes in water) with walls that were 12.7 centimetres (5.0 in) thick. Krupp Steel Works was also contracted in the mid-1960s to construct the
Effelsberg 100-m Radio Telescope, which, from 1972 to 2000 was the largest fully steerable
radio telescope in the world.
Peacetime activities Railway expansion period Krupp was the first company to patent a seamless, reliable and strong enough railway tyre for rail freight. Krupp received original contracts in the United States and enjoyed a period of technological superiority while also contributing the majority of rail to the new continental railway system. "Nearly all railroads were using Krupp rails, the
New York Central,
Illinois Central,
Delaware and Hudson,
Maine Central,
Lake Shore and Michigan Southern,
Bangor and Aroostook,
Great Northern,
Boston and Albany,
Florida and East Coast,
Texas and Pacific,
Southern Pacific, and
Mexican National."
Diesel engines In 1893, a mechanical engineer by the name of
Rudolf Diesel approached Gustav with a patent for a "new kind of internal combustion engine employing autoignition of the fuel". He also included his text "". Four years later, the first 3-
horsepower diesel engine was produced. ==Pronunciation==
