Bremen-class Cruiser
The class was a group of seven light cruisers built for the Imperial German Navy in the early 1900s. The seven ships, , , , , , , and , were an improvement upon the previous . They were significantly larger than the earlier class, and were faster and better armored. Like the s, they were armed with a main battery of ten 10.5 cm SK L/40 guns and a pair of torpedo tubes. The ships of the class served in a variety of roles, from overseas cruiser to fleet scout to training ship. and were deployed to the American and Asian stations, respectively, while the other five ships remained in German waters with the High Seas Fleet. At the outbreak of World War I in August 1914, was in the Pacific Ocean in the East Asia Squadron; she saw action at the Battle of Coronel in November and was sunk a month later at the Battle of the Falkland Islands. was sunk by a Russian mine in December 1915, but the other five ships of the class survived the war.

Light Cruiser
A light cruiser is a type of small or medium-sized warship. The term is a shortening of the phrase "light armored cruiser", describing a small ship that carried armor in the same way as an armored cruiser: a protective belt and deck. Prior to this smaller cruisers had been of the protected cruiser model, possessing armored decks only. While lighter and smaller than other contemporary ships they were still true cruisers, retaining the extended radius of action and self-sufficiency to act independently around the world. Through their history they served in a variety of roles, primarily as convoy escorts and destroyer command ships, but also as scouts and fleet support vessels for battle fleets. Origins and development The first small steam-powered cruisers were built for the British Royal Navy with HMS ''Mercury'' launched in 1878. Such second and third class protected cruisers evolved, gradually becoming faster, better armed and better protected. Germany took a lead in small crui ...

Battle Of The Falkland Islands
The Battle of the Falkland Islands was a First World War naval action between the British Royal Navy and Imperial German Navy on 8 December 1914 in the South Atlantic. The British, after their defeat at the Battle of Coronel on 1 November, sent a large force to track down and destroy the German cruiser squadron. The battle is commemorated every year on 8 December in the Falkland Islands as a public holiday.

Hanseatic League
The Hanseatic League (; gml, Hanse, , ; german: label=Modern German, Deutsche Hanse) was a medieval commercial and defensive confederation of merchant guilds and market towns in Central and Northern Europe. Growing from a few North German towns in the late 12th century, the League ultimately encompassed nearly 200 settlements across seven modern-day countries; at its height between the 13th and 15th centuries, it stretched from the Netherlands in the west to Russia in the east, and from Estonia in the north to Kraków, Poland in the south. The League originated from various loose associations of German traders and towns formed to advance mutual commercial interests, such as protection against piracy and banditry. These arrangements gradually coalesced into the Hanseatic League, whose traders enjoyed duty-free treatment, protection, and diplomatic privileges in affiliated communities and their trade routes. Hanseatic Cities gradually developed a common legal system governing t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaiser Wilhelm II
Wilhelm II (Friedrich Wilhelm Viktor Albert; 27 January 18594 June 1941) was the last German Emperor (german: Kaiser) and List of monarchs of Prussia, King of Prussia, reigning from 15 June 1888 until Abdication of Wilhelm II, his abdication on 9 November in German history, 9 November 1918. Despite strengthening the German Empire's position as a great power by building a powerful navy, his tactless public statements and erratic foreign policy greatly antagonized the international community and are considered by many to be one of Causes of World War I, the underlying causes of World War I. When the German war effort collapsed after a series of crushing defeats on the Western Front (World War I), Western Front in 1918, he was forced to abdicate, thereby marking the end of the German Empire and the House of Hohenzollern's 300-year reign in Prussia and 500-year reign in Margraviate of Brandenburg, Brandenburg.

Triple-expansion Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reichsmarineamt
The Imperial Naval Office (german: Reichsmarineamt) was a government agency of the German Empire. It was established in April 1889, when the German Imperial Admiralty was abolished and its duties divided among three new entities: the Imperial Naval High Command (''Kaiserliches Oberkommando der Marine''), the Imperial Naval Cabinet (''Kaiserliches Marinekabinett'') and the Imperial Naval Office performing the functions of a ministry for the Imperial German Navy. Structure and tasks According to the 1871 Constitution of the German Empire, the federal states were responsible for the German land forces and the imperial government for the navy. So while there were Prussian, Bavarian, Saxon and Württemberg armies, there was a single Imperial Navy, the only formation under the direct authority of the German Reich beside the colonial ''Schutztruppe'' forces. The head of the Naval Office was a Secretary of State who reported directly to the Imperial Chancellor (''Reichskanzler''). W ...

Alfred Von Tirpitz
Alfred Peter Friedrich von Tirpitz (19 March 1849 – 6 March 1930) was a German grand admiral, Secretary of State of the German Imperial Naval Office, the powerful administrative branch of the German Imperial Navy from 1897 until 1916. Prussia never had a major navy, nor did the other German states before the German Empire was formed in 1871. Tirpitz took the modest Imperial Navy and, starting in the 1890s, turned it into a world-class force that could threaten Britain's Royal Navy. However, during World War I, his High Seas Fleet proved unable to end Britain's command of the sea and its chokehold on Germany's economy. The one great engagement at sea, the Battle of Jutland, ended in a narrow German tactical victory but a strategic failure. As the High Seas Fleet's limitations became increasingly apparent during the war, Tirpitz became an outspoken advocate for unrestricted submarine warfare, a policy which would ultimately bring Germany into conflict with the United States.

German Naval Laws
The Naval Laws (german: Flottengesetze, "Fleet Laws") were five separate laws passed by the German Empire, in 1898, 1900, 1906, 1908, and 1912. These acts, championed by Kaiser Wilhelm II and his Secretary of State for the Navy, Grand Admiral Alfred von Tirpitz, committed Germany to building up a navy capable of competing with the Royal Navy of the United Kingdom. German desires and the strategic debate The Kaiser had long wanted a large naval force to assure Germany of what he called " a place in the sun". A large German navy could assist in German attempts to attain colonies, as well as further the country's economic and commercial interests elsewhere in the world. He was determined to make his country a colonial power in Africa and the Pacific. He was also a very militaristic man, and wished to increase the strength of the German armed forces; in particular he wanted to develop a navy that could match the British Royal Navy. As he wrote in his autobiography: Though Wilhel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SMS Medusa
SMS was a member of the ten-ship of light cruisers that were built for the German (Imperial Navy) in the late 1890s and early 1900s. The class was the culmination of earlier unprotected cruiser and aviso designs, combining the best aspects of both types in what became the progenitor of all future light cruisers of the Imperial fleet. Built to be able to serve with the main German fleet and as a colonial cruiser, she was armed with a battery of ten guns and a top speed of . served in all three German navies—the , the (Navy of the Realm) of Weimar Germany, and the (War Navy) of Nazi Germany—over the span of over forty years. During her career in the Imperial fleet, she served in the reconnaissance unit for the High Seas Fleet from 1903 to 1907; during this period, she took part in cruises overseas and routine training exercises. She temporarily replaced her sister ship as a gunnery training ship in 1908 while the latter was undergoing repairs. was herself ove ...
