König-class Battleship
The ''König'' class was a group of four dreadnought battleships built for the German (Imperial Navy) in the early 1910s. The class comprised , the lead ship, , , and . The design for the ships was derived from the preceding , using the same basic hull but with a rearranged main battery of ten guns in five twin- gun turrets to improve the guns' firing arcs. Instead of the staggered wing turrets used in the ''Kaiser''s, the ''König''s placed their main guns all on the centerline using superfiring pairs fore and aft. Budgetary constraints and the need to begin construction quickly to compete with Britain in the Anglo-German naval arms race prevented any more radical changes. Diesel engines were planned for the ships, but they could not be readied in time, so all four vessels reverted to steam turbines for their propulsion system. As tensions in Europe spiraled out of control during the July Crisis in 1914, work on the ships was accelerated; all four ships were completed in ...

Dreadnought Battleship
The dreadnought (alternatively spelled dreadnaught) was the predominant type of battleship in the early 20th century. The first of the kind, the Royal Navy's , had such an impact when launched in 1906 that similar battleships built after her were referred to as "dreadnoughts", and earlier battleships became known as pre-dreadnoughts. Her design had two revolutionary features: an "all-big-gun" armament scheme, with an unprecedented number of heavy-calibre guns, and steam turbine propulsion. As dreadnoughts became a crucial symbol of national power, the arrival of these new warships renewed the Causes of World War I#Arms race, naval arms race between the Anglo–German naval arms race, United Kingdom and Germany. Dreadnought races sprang up around the world, including South American dreadnought race, in South America, lasting up to the beginning of World War I. Successive designs increased rapidly in size and made use of improvements in armament, armour and propulsion throughou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...

I Scouting Group
The I Scouting Group (german: I. Aufklärungsgruppe) was a special reconnaissance unit within the German Kaiserliche Marine. The unit was famously commanded by Admiral Franz von Hipper during World War I. The I Scouting Group was one of the most active formations in the High Seas Fleet during the war; the unit took part in every major fleet operation in the North Sea, including the battles of Dogger Bank and Jutland. The unit also saw limited action in the Baltic Sea, including the Battle of the Gulf of Riga. Ships assigned to the I Scouting Group was the first battlecruiser assigned to the I Scouting group. The ship joined the unit on 8 May 1911. On 30 September, was commissioned into the I Scouting Group, and replaced the old armored cruiser .Staff, p. 15 joined the unit after she was commissioned on 22 May 1913. was attached to the unit from August 1914. was slated to be assigned to the unit by the end of October 1914, but turbine damage delayed the ship from joining the ...

Battlecruiser
The battlecruiser (also written as battle cruiser or battle-cruiser) was a type of capital ship of the first half of the 20th century. These were similar in displacement, armament and cost to battleships, but differed in form and balance of attributes. Battlecruisers typically had thinner armour (to a varying degree) and a somewhat lighter main gun battery than contemporary battleships, installed on a longer hull with much higher engine power in order to attain greater speeds. The first battlecruisers were designed in the United Kingdom, as a development of the armoured cruiser, at the same time as the dreadnought succeeded the pre-dreadnought battleship. The goal of the design was to outrun any ship with similar armament, and chase down any ship with lesser armament; they were intended to hunt down slower, older armoured cruisers and destroy them with heavy gunfire while avoiding combat with the more powerful but slower battleships. However, as more and more battlecruisers we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Seas Fleet
The High Seas Fleet (''Hochseeflotte'') was the battle fleet of the German Imperial Navy and saw action during the First World War. The formation was created in February 1907, when the Home Fleet (''Heimatflotte'') was renamed as the High Seas Fleet. Admiral Alfred von Tirpitz was the architect of the fleet; he envisioned a force powerful enough to challenge the Royal Navy's predominance. Kaiser Wilhelm II, the German Emperor, championed the fleet as the instrument by which he would seize overseas possessions and make Germany a global power. By concentrating a powerful battle fleet in the North Sea while the Royal Navy was required to disperse its forces around the British Empire, Tirpitz believed Germany could achieve a balance of force that could seriously damage British naval hegemony. This was the heart of Tirpitz's "Risk Theory", which held that Britain would not challenge Germany if the latter's fleet posed such a significant threat to its own. The primary component ...

III Battle Squadron
The III Battle Squadron was a unit of the German High Seas Fleet before and during World War I. The squadron saw action throughout the war, including the Battle of Jutland on 31 May – 1 June 1916, where it formed the front of the German line. The ships were interned in Scapa Flow after the end of the war, where they were scuttled by their crews. Most of the ships of the squadron were raised for scrapping, though three remain on the bottom of the harbor. Organization The III Battle Squadron was divided into the V Division and the VI Division. For the first half of the wartime service of these divisions, they contained the and es, respectively. During this period, the battleship served as the flagship of both the squadron and the V Division, while the battleship served as the flagship of the VI Division.Tarrant, p. 286 On 1 December 1916, the five ''Kaiser''-class ships were transferred to the newly re-formed IV Battle Squadron while the new battleships and took their pl ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was List of wars and anthropogenic disasters by death toll, one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific Ocean, Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in Genocides in history (World War I through World War II), genocides within the Ottoman Empire and in the Spanish flu, 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising French Third Republic, France, Russia, and British Empire, Britain) and the Triple A ...

July Crisis
The July Crisis was a series of interrelated diplomatic and military escalations among the major powers of Europe in the summer of 1914, which led to the outbreak of World War I (1914–1918). The crisis began on 28 June 1914, when Gavrilo Princip, a Bosnian Serb, assassinated Archduke Franz Ferdinand, heir presumptive to the Austro-Hungarian throne, and his wife Sophie, Duchess of Hohenberg. The assassin team was armed, trained, smuggled across the border and instructed by the head of the Serbian military intelligence service and his staff. A complex web of alliances, coupled with miscalculations when many leaders regarded war as in their best interests or felt that a general war would not occur, resulted in a general outbreak of hostilities among most major European nations in early August 1914. Austria-Hungary viewed the irredentist movements of South Slavs, as promoted by Serbia, as a threat to the unity of its multi-national empire. Following the assassination, Austria s ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine ( gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglo-German Naval Arms Race
The arms race between Great Britain and Germany that occurred from the last decade of the nineteenth century until the advent of World War I in 1914 was one of the intertwined causes of that conflict. While based in a bilateral relationship that had worsened over many decades, the arms race began with a plan by German Admiral Alfred von Tirpitz in 1897 to create a fleet in being to force Britain to make diplomatic concessions; Tirpitz did not expect the Imperial German Navy to defeat the Royal Navy. With the support of Kaiser Wilhelm II, Tirpitz began passing a series of laws to construct an increasing number of large surface warships. The construction of in 1906 prompted Tirpitz to further increase the rate of naval construction. While some British observers were uneasy at German naval expansion, alarm was not general until Germany's naval bill of 1908. The British public and political opposition demanded that the Liberal government meet the German challenge, resulting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superfire
Superfiring armament is a naval military building technique in which two (or more) turrets are located in a line, one behind the other, with the second turret located above ("super") the one in front so that the second turret can fire over the first. This configuration meant that both forward or aft turrets could fire at any target within their sector, even when the target was in the same vertical plane as the turrets. History The history of large surface warships follow generic labels as battleships, and a further distinction between pre-dreadnoughts and dreadnoughts. The era of technical evolution occurred roughly from 1900 to 1945. Part of the technical evolution was driven by the need to compress as much large-gun firepower into the smallest space possible. In early designs, the large-caliber turrets were all located on the same plane firing to one side or the other. In firing ahead or to the rear, usually only the forward-most or rearmost turret could fire, especially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
