Imperial German Navy

The Imperial German Navy or the Kaiserliche Marine (Imperial Navy) was the navy of the German Empire, which existed between 1871 and 1919. It grew out of the small Prussian Navy (from 1867 the North German Federal Navy), which was mainly for coast defence. Kaiser Wilhelm II greatly expanded the navy. The key leader was Admiral Alfred von Tirpitz, who greatly expanded the size and quality of the navy, while adopting the sea power theories of American strategist Alfred Thayer Mahan. The result was a naval arms race with Britain, as the German navy grew to become one of the greatest maritime forces in the world, second only to the Royal Navy.

The German surface navy proved ineffective during the First World War; its only major engagement, the Battle of Jutland, was a draw, but it kept the surface fleet largely in port for the rest of the war. The submarine fleet was greatly expanded and threatened the British supply system during the U-boat campaign. As part of the Armistice, the Imperial Navy's main ships were ordered to be turned over to the Allies but they were instead scuttled by their own crews. All ships of the Imperial Navy bore the prefix SMS, for Seiner Majestät Schiff (His Majesty's Ship).

The Imperial Navy achieved some important operational feats. At the Battle of Coronel, it inflicted the first major defeat on the Royal Navy in over one hundred years, although the German squadron of ships was subsequently defeated at the Battle of the Falkland Islands, only one ship escaping destruction. The Navy also emerged from the fleet action of the Battle of Jutland having destroyed more ships than it lost, although the strategic value of both of these encounters was minimal.^{[citation needed]}

The Imperial Navy was the first to operate submarines successfully on a large scale in wartime, with 375 submarines commissioned by the end of the First World War, and it also operated zeppelins. Although it was never able to match the number of ships of the Royal Navy, it had technological advantages, such as better shells^{[citation needed]} and propellant for much of the Great War, meaning that it never lost a ship to a catastrophic magazine explosion from an above-water attack,^{[citation needed]} although the elderly pre-dreadnought SMS Pommern sank rapidly at Jutland after a magazine explosion was caused by an underwater attack.

The unification of Germany under Prussian leadership was the defining point for the creation of the Imperial Navy in 1871. The newly created emperor, Wilhelm I, as King of Prussia, had previously been head of state of the strongest state forming part of the new empire. The navy remained the same as that operated by the empire's predecessor organisation in the unification of Germany, the North German Confederation, which itself in 1867 had inherited the navy of the Kingdom of Prussia. Article 53 of the new Empire's constitution recognised the existence of the Navy as an independent organisation, but until 1888 it was commanded by army officers and initially adopted the same regulations as the Prussian army. Supreme command was vested in the emperor, but its first appointed chief was General der Infanterie (General of the Infantry) Albrecht von Stosch. Kiel on the Baltic Sea and Wilhelmshaven on the North Sea served as the Navy's principal naval bases. The former Navy Ministry became the Imperial Admiralty on 1 February 1872, while Stosch became formally an admiral in 1875. Initially the main task of the new Imperial Navy was coastal protection, with France and Russia seen as Germany's most likely future enemies. The Imperial Navy's tasks were then to prevent any invasion force from landing and to protect coastal towns from possible bombardment.

In March 1872 a German Imperial Naval Academy was created at Kiel for training officers, followed in May by the creation of a 'Machine Engineer Corps', and in February 1873 a 'Medical Corps'. In July 1879 a separate 'Torpedo Engineer Corps' was created dealing with torpedoes and mines. In May 1872 a ten-year building programme was instituted to modernise the fleet. This called for eight armoured frigates, six armoured corvettes, twenty light corvettes, seven monitors, two floating batteries, six avisos, eighteen gunboats and twenty-eight torpedo boats, at an estimated cost of 220 million gold marks. The building plan had to be approved by the Reichstag, which controlled the allocation of funds, although one-quarter of the money came from French war reparations.

In 1883 Stosch was replaced by another general, Count Leo von Caprivi. At this point the navy had seven armoured frigates and four armoured corvettes, 400 officers and 5,000 ratings. The objectives of coastal defence remained largely unchanged, but there was a new emphasis on development of the torpedo, which offered the possibility of relatively small ships successfully attacking much larger ones. In October 1887 the first torpedo division was created at Wilhelmshaven and the second torpedo division based at Kiel. In 1887 Caprivi requested the construction of ten armoured frigates.

Greater importance was placed at this time on development of the army, which was expected to be more important in any war. However, the Kiel Canal was commenced in June 1887, which connected the North Sea with the Baltic through the Jutland peninsula, allowing German ships to travel between the two seas avoiding waters controlled by other countries. This shortened the journey for commercial ships, but specifically united the two areas principally of concern to the German navy, at a cost of 150 million marks. Later, the protection of German maritime trade routes became important. This soon involved the setting up of some overseas supply stations, so called Auswärtige Stationen (foreign stations) and in the 1880s the Imperial Navy played a part in helping to secure the establishment of German colonies and protectorates in Africa, Asia and Oceania.
