Q:Information: - The Imperial German Navy ("Imperial Navy") was the navy created at the time of the formation of the German Empire. It existed between 1871 and 1919, growing out of the small Prussian Navy (from 1867 the "Norddeutsche Bundesmarine"), which primarily had the mission of coastal defence. Kaiser Wilhelm II greatly expanded the navy, and enlarged its mission. 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 World War I; its only major engagement, the Battle of Jutland, was indecisive. However, the submarine fleet was greatly expanded and posed a major threat to the British supply system. The Imperial Navy's main ships were turned over to the Allies, but then were sunk at Scapa Flow in 1919 by German crews. - The unification of Germany into a politically and administratively integrated nation state officially occurred on 18 January 1871 in the Hall of Mirrors at the Palace of Versailles in France. Princes of the German states gathered there to proclaim Wilhelm I of Prussia as German Emperor after the French capitulation in the Franco-Prussian War. Unofficially, the "de facto" transition of most of the German-speaking populations into a federated organization of states had been developing for some time through alliances formal and informal between princely rulersbut in fits and starts; self-interests of the various parties hampered the process over nearly a century of autocratic experimentation, beginning in the era of the Napoleonic Wars, which saw the dissolution of the Holy Roman Empire (1806), and the subsequent rise of German nationalism. - In general, a civilian is "a person who is not a member of the military or of a police or firefighting force", as defined by Merriam Webster's Dictionary. From the perspective of the U.S. Department of Defense, Chapter 18 of Title 10 United States Code refers to non-military law enforcement officers as civilians since they are employees rather than enlisted personnel, and also in order to distinguish itself from military police. In military and law enforcement slang, the term "Civies" or "Civvies" are often used to refer civilian population or civilian clothing. - Kaiserliche Werft Danzig was a German shipbuilding company founded in 1852 as "Konigliche Werft Danzig" and renamed "Kaiserliche Werft" after the proclamation of the German Empire in 1871. Together with Kaiserliche Werft Kiel and Kaiserliche Werft Wilhelmshaven it was one of three shipyards responsible for maintenance, repair and construction of warships for the Imperial German Navy. "Kaiserliche Werft Danzig" closed in 1918 after the end of World War I, but soon opened when Danziger Werft was founded on its site in 1919. - World War I (WWI or WW1), also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. - U-boat is the anglicised version of the German word U-Boot , a shortening of Unterseeboot, literally "undersea boat". While the German term refers to any submarine, the English one (in common with several other languages) refers specifically to military submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding), enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada, the British Empire, and the United States to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. - The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states. It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, % of the world population at the time, and by 1920, it covered , % of the Earth's total land area. As a result, its political, legal, linguistic and cultural legacy is widespread. At the peak of its power, the phrase "the empire on which the sun never sets" was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories. - Weimar Republic is an unofficial, historical designation for the German state between 1919 and 1933. The name derives from the city of Weimar, where its constitutional assembly first took place. The official name of the state was still "Deutsches Reich"; it had remained unchanged since 1871. In English the country was usually known simply as Germany. A national assembly was convened in Weimar, where a new constitution for the "Deutsches Reich" was written, and adopted on 11 August 1919. In its fourteen years, the Weimar Republic faced numerous problems, including hyperinflation, political extremism (with paramilitaries both left- and right-wing); and contentious relationships with the victors of the First World War. The people of Germany blamed the Weimar Republic rather than their wartime leaders for the country's defeat and for the humiliating terms of the Treaty of Versailles. However, the Weimar Republic government successfully reformed the currency, unified tax policies, and organized the railway system. Weimar Germany eliminated most of the requirements of the Treaty of Versailles; it never completely met its disarmament requirements, and eventually paid only a small portion of the war reparations (by twice restructuring its debt through the Dawes Plan and the Young Plan). Under the Locarno Treaties, Germany accepted the western borders of the republic, but continued to dispute the Eastern border. - A submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term most commonly refers to a large, crewed vessel. It is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Used as an adjective in phrases such as "submarine cable", "submarine" means "under the sea". The noun "submarine" evolved as a shortened form of "submarine boat" (and is often further shortened to "sub"). For reasons of naval tradition, submarines are usually referred to as "boats" rather than as "ships", regardless of their size. - The German Empire (officially ') was the historical German nation state that existed from the unification of Germany in 1871 to the abdication of Kaiser Wilhelm II in November 1918, when Germany became a federal republic (the Weimar Republic). - Kaiserliche Werft Kiel ("Imperial shipyard Kiel") was a German shipbuilding company founded in 1867, first as Konigliche Werft Kiel but renamed in 1871 with the proclamation of the German Empire. Together with Kaiserliche Werft Danzig and Kaiserliche Werft Wilhelmshaven it was one of three shipyards which produced warships for the Preuische Marine and later the Kaiserliche Marine. With the end of World War I "Kaiserliche Werft Kiel" was closed but the shipyard was opened again when Deutsche Werke was founded on their grounds in 1925. - SM U- 3 was the third German U-Boat created by the German Empire in their history , and the first of two submarines in its class . The boat was built by Kaiserliche Werft Danzig and was launched on 27 March 1909 . U- 3 began its career in World War I as a training boat from 1 August 1914 to 11 November 1918 . On 1 December 1918 , the surrendered boat was being towed to Preston to be broken up when it sank . Unlike the first two U-boat designs , the third design was fitted with a 5 cm ( 2.0 in ) SK L / 40 deck gun . What entity does 'sm u-3 ' has the relation 'operator' with?
