The Imperial German Navy or the (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 coastal 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 (His Majesty's Ship).
Achievements 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.
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 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, although the elderly pre-dreadnought sank rapidly at Jutland after a magazine explosion was caused by an underwater attack.
1871 to 1888, Kaiser Wilhelm I
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 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.
1888 to 1897, under Kaiser Wilhelm II
In June 1888 Wilhelm II became Emperor after the death of his father Frederick III, who ruled for only 99 days. He started his reign with the intention of doing for the navy what his grandfather Wilhelm I had done for the army. The creation of a maritime empire to rival the British and French empires became an ambition to mark Germany as a truly global great power. Wilhelm became Grand Admiral of the German Navy, but also was awarded honorific titles from all over Europe, becoming admiral in the British, Russian, Swedish, Danish, Norwegian, Austro-Hungarian and Greek navies. On one occasion he wore the uniform of a British admiral to receive the visiting British ambassador. At this time the Imperial Navy had 534 officers and 15,480 men.
The concept of expanding naval power, inevitably at the cost of not expanding other forces, was opposed by the three successive heads of the German armed forces, Waldersee, Schlieffen and Moltke between 1888 and 1914. It would also have been more widely opposed, had the Kaiser's intentions been widely known. Instead, he proceeded with a plan to expand the navy slowly, justifying enlargement step by step. In July 1888 Wilhelm II appointed Vice-Admiral Alexander von Monts as head of the admiralty. Monts oversaw the design of the , four of which were constructed by 1894 at a cost of 16 million marks each and displacement of 10,000 tons.
In 1889 Wilhelm II reorganised top level control of the navy by creating a Navy Cabinet (Marine-Kabinett) equivalent to the German Imperial Military Cabinet which had previously functioned in the same capacity for both the army and navy. The Head of the navy cabinet was responsible for promotions, appointments, administration and issuing orders to naval forces. Captain Gustav von Senden-Bibran was appointed as its first head and remained so until 1906, when he was replaced by the long-serving Admiral Georg Alexander von Müller. The existing Imperial admiralty was abolished and its responsibilities divided between two organisations. A new position of Chief of the Imperial Naval High Command was created, being responsible for ship deployments, strategy and tactics, an equivalent to the supreme commander of the Army. Vice admiral Max von der Goltz was appointed in 1889 and remained in post until 1895. Construction and maintenance of ships and obtaining supplies was the responsibility of the State Secretary of the Imperial Navy Office (Reichsmarineamt), responsible to the chancellor and advising the Reichstag on naval matters. The first appointee was Rear Admiral Karl Eduard Heusner, followed shortly by Rear Admiral Friedrich von Hollmann from 1890 to 1897. Each of these three heads of department reported separately to Wilhelm II.
In 1895 funding was agreed for five battleships of the , completed by 1902. The ships were innovative for their time, introducing a complex system of watertight compartments and storing coal along the sides of the ship to help absorb explosions. However, the ships went against the trend for increasingly larger main guns, having smaller diameter guns than the Brandenburg design, but with a quick-loading design and more powerful secondary armaments. Costs rose to 21 million marks each, as had size to 11,500 tons.
In 1892 Germany had launched the protected cruiser , the first navy ship to have triple propellers. She was succeeded by five protected cruisers, the last 'protected', as distinct from 'armoured' cruiser class constructed by Germany. The ships, completed between 1898 and 1900, had deck armour but not side armour and were intended for overseas duties. Shortages of funding meant it was not possible to create several designs of cruisers specialised for long range work, or more heavily armoured for fleet work. Work commenced on an armoured cruiser design, started in 1896 and commissioned in 1900.
1897 to 1906, Tirpitz and the Navy bills
On 18 June 1897 Rear-Admiral Alfred von Tirpitz was appointed State Secretary of the Navy, where he remained for nineteen years. Tirpitz advocated the cause of an expanded navy necessary for Germany to defend her territories abroad. He had great success in persuading parliament to pass successive Navy bills authorising expansions of the fleet. German foreign policy as espoused by Otto von Bismarck had been to deflect the interest of great powers abroad while Germany consolidated her integration and military strength. Now Germany was to compete with the rest. Tirpitz started with a publicity campaign aimed at popularising the navy. He created popular magazines about the navy, arranged for Alfred Thayer Mahan's The Influence of Sea Power upon History, which argued the importance of naval forces, to be translated into German and serialised in newspapers, arranged rallies in support and invited politicians and industrialists to naval reviews. Various pressure groups were formed to lobby politicians and spread publicity. One such organisation, the navy league or Flottenverein, was organized by principals in the steel industry (Alfred Krupp), ship yards and banks, gaining more than one million members. Political parties were offered concessions, such as taxes on imported grain, in exchange for their support for naval bills.
On 10 April 1898 the first Navy Bill was passed by the Reichstag. It authorised the maintenance of a fleet of 19 battleships, 8 armoured cruisers, 12 large cruisers and 30 light cruisers to be constructed by 1 April 1904. Existing ships were counted in the total, but the bill provided for ships to be replaced every 25 years on an indefinite basis. Five million marks annually was allocated to run the navy, with a total budget of 408 million marks for shipbuilding. This would bring the German fleet to a strength where it could contemplate challenging France or Russia, but would remain clearly inferior to the world's largest fleet, the Royal Navy.
