Derfflinger-class Battlecruiser
The class was a class of three battlecruisers (german: Schlachtkreuzer, links=no) of the Imperial German Navy. The ships were ordered for the 1912–13 Naval Building Program of the German Imperial Navy as a reply to the Royal Navy's two new s that had been launched a few years earlier. The preceding and the incrementally improved represented the end of the evolution of Germany's first generation of battlecruisers. The class had considerable improvements, including a larger primary armament, all of which was mounted on the centerline. The ships were also larger than the preceding classes. The class used a similar propulsion system, and as a result of the increased displacement were slightly slower. The class comprised three ships: , , and . All three of the ships saw active service with the High Seas Fleet during World War I. was commissioned shortly after the outbreak of war, and was present at most of the naval actions in the North Sea, including the battles of Dogger Ban ...

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 were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwig Von Reuter
Hans Hermann Ludwig von Reuter (9 February 1869 – 18 December 1943) was a German admiral who commanded the High Seas Fleet when it was interned at Scapa Flow in the north of Scotland at the end of World War I. On 21 June 1919 he ordered the scuttling of the German fleet in Scapa Flow to prevent the UK from seizing the ships. Early life Reuter was born in Guben into a Prussian military family. His father, a colonel in the army, was killed in the Franco-Prussian War. In 1885, he became a cadet in the Imperial German Navy at the instigation of his mother. As a midshipman at the age of 17, he was promoted to '' Unterleutnant zur See'' in 1888. By 1910, he was a ''Kapitän zur See'', commanding the armored cruiser .Van der Vat, 1982, pp. 109–111. World War I Two months after the outbreak of World War I, he was made captain of the battlecruiser , which he also commanded during the Battle of Dogger Bank. In September 1915, he became Commodore and commanding officer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm II
Wilhelm II (Friedrich Wilhelm Viktor Albert; 27 January 18594 June 1941) was the last German Emperor (german: Kaiser) and King of Prussia, reigning from 15 June 1888 until his abdication on 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 the underlying causes of World War I. When the German war effort collapsed after a series of crushing defeats on the 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 Brandenburg. Wilhelm II was the son of Prince Frederick William of Prussia and Victoria, German Empress Consort. His father was the son of Wilhelm I, German Emperor, and his mother was the eldest daughter of Queen Victoria of the United Kingdom and ...

Parliament Of The United Kingdom
The Parliament of the United Kingdom is the supreme legislative body of the United Kingdom, the Crown Dependencies and the British Overseas Territories. It meets at the Palace of Westminster, London. It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and the overseas territories. Parliament is bicameral but has three parts, consisting of the sovereign ( King-in-Parliament), the House of Lords, and the House of Commons (the primary chamber). In theory, power is officially vested in the King-in-Parliament. However, the Crown normally acts on the advice of the prime minister, and the powers of the House of Lords are limited to only delaying legislation; thus power is ''de facto'' vested in the House of Commons. The House of Commons is an elected chamber with elections to 650 single-member constituencies held at least every five years under the first-past-the-post system. By constitutional convention, all governme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo Bulkhead
A torpedo bulkhead is a type of naval armour common on the more heavily armored warships, especially battleships and battlecruisers of the early 20th century. It is designed to keep the ship afloat even if the hull is struck underneath the belt armor by a shell or by a torpedo. History After the lessons learned during World War I, many capital ships were refitted with double, triple, or even quadruple torpedo bulkheads, as well as anti-torpedo bulges to the exterior of the hull.Gillmer and Johnson, p.185 For example, the last US battleship designs during World War II had up to four torpedo bulkheads and a triple-bottom. The innermost bulkhead is commonly referred to as the ''holding bulkhead'', and often this bulkhead would be manufactured from high tensile steel that could deform and absorb the pressure pulse from a torpedo hit without breaking. If the final bulkhead was at least 37 mm thick, it may also be referred to as an ''armored bulkhead'', as it would be capable of st ...

Line Of Battle
The line of battle is a tactic in naval warfare in which a fleet of ships forms a line end to end. The first example of its use as a tactic is disputed—it has been variously claimed for dates ranging from 1502 to 1652. Line-of-battle tactics were in widespread use by 1675. Compared with prior naval tactics, in which two opposing ships closed on one another for individual combat, the line of battle has the advantage that each ship in the line can fire its broadside without fear of hitting a friendly ship. This means that in a given period, the fleet can fire more shots. Another advantage is that a relative movement of the line in relation to some part of the enemy fleet allows for a systematic concentration of fire on that part. The other fleet can avoid this by manoeuvring in a line itself, with a result typical for sea battles since 1675: two fleets sail alongside one another (or on the opposite tack). Early development The first recorded mention of the use of a line of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Dreadnought
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 naval arms race between the United Kingdom and Germany. Dreadnought races sprang up around the world, including 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 throughout the dreadnought era. Within five years, new battleships outclassed ''Dreadnought'' herself. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reichstag (German Empire)
The Reichstag () of the German Empire was Germany's lower house of parliament from 1871 to 1918. Within the governmental structure of the Reich, it represented the national and democratic element alongside the federalism of the Bundesrat and the monarchic and bureaucratic element of the executive, embodied in the Reich chancellor. Together with the Bundesrat, the Reichstag had legislative power and shared in decision-making on the Reich budget. It also had certain rights of control over the executive branch and could engage the public through its debates. The emperor had little political power, and over time the position of the Reichstag strengthened with respect to the Bundesrat. Reichstag members were elected for three year terms from 1871 to 1888 and following that for five years. It had one of the most progressive electoral laws of its time: with only a few restrictions, all men 25 and older were allowed to vote, secretly and equally. The Reichstag met throughout the First Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agadir Crisis
The Agadir Crisis, Agadir Incident, or Second Moroccan Crisis was a brief crisis sparked by the deployment of a substantial force of French troops in the interior of Morocco in April 1911 and the deployment of the German gunboat to Agadir, a Moroccan Atlantic port. Germany did not object to France's expansion but wanted territorial compensation for itself. Berlin threatened warfare, sent a gunboat, and stirred up German nationalists. Negotiations between Berlin and Paris resolved the crisis on 4 November 1911: France took over Morocco as a protectorate in exchange for territorial concessions to German Cameroon from the French Congo. In Britain, David Lloyd George, then Chancellor of the Exchequer, made a dramatic " Mansion House" speech on 21 July 1911 – with the consent of the prime minister and Foreign Secretary Sir Edward Grey, bypassing the non-interventionist majority in the Cabinet – that denounced the German move as an intolerable humiliation. There was ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
