Kaiser-class Battleship
The class was a class of five dreadnought battleships that were built in Germany prior to World War I and served in the (Imperial Navy) during the war. They were the third class of German dreadnoughts, and the first to feature turbine engines and superfiring turrets. The five ships were , , , , and . As was usual for German battleships of the period, the class mounted main guns that were smaller than those of their British rivals: , compared to the guns of the British . All five ships saw action in the North Sea during the war; they served together as VI Division of III Battle Squadron. Four were present during the Battle of Jutland; was in dock at the time. Of the four ships that took part in the battle, only was damaged, being struck by two heavy-caliber shells. The ships also took part in Operation Albion in the Baltic Sea; during the operation they were reorganized as IV Battle Squadron, under the command of Vice Admiral Wilhelm Souchon. At the end of the war, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 throughout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Watertight Compartment
A compartment is a portion of the space within a ship defined vertically between decks and horizontally between bulkheads. It is analogous to a room within a building, and may provide watertight subdivision of the ship's hull important in retaining buoyancy if the hull is damaged. Subdivision of a ship's hull into watertight compartments is called compartmentation. History Bulkhead watertight compartments were originally invented by the Chinese. These compartments strengthened the junks and slowed flooding in case of holing during the Han and Song dynasties. The wide application of Chinese watertight compartments soon spread to the Europeans through the Indian and Arab merchants. The economics of early unsinkable passenger ships was scrutinized in an 1882 Scientific American article. Watertight subdivision Watertight subdivision limits loss of buoyancy and freeboard in the event of damage, and may protect vital machinery from flooding. Most ships have some pumping capacit ...

Double Bottom
A double hull is a ship Hull (watercraft), hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard, typically by a few feet, which forms a redundant barrier to seawater in case the outer hull is damaged and leaks. The space between the two hulls is sometimes used for storage of ballast water. Double hulls are a more extensive safety measure than double bottoms, which have two hull layers only in the bottom of the ship but not the sides. In low-energy collisions, double hulls can prevent flooding beyond the penetrated compartment. In high-energy collisions, however, the distance to the inner hull is not sufficient and the inner compartment is penetrated as well. Double hulls or double bottoms have been required in all passenger ships for decades as part of the International Convention for the Safety of L ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Length At The Waterline
A vessel's length at the waterline (abbreviated to L.W.L)Note: originally Load Waterline Length is the length of a ship or boat at the level where it sits in the water (the ''waterline''). The LWL will be shorter than the length of the boat overall (''length overall'' or LOA) as most boats have bows and stern protrusions that make the LOA greater than the LWL. As a ship becomes more loaded, it will sit lower in the water and its ambient waterline length may change; but the registered L.W.L it is measured from a default load condition. This measure is significant in determining several of a vessel's properties, such as how much water it displaces, where the bow and stern waves occur, hull speed, amount of bottom-paint needed, etc. Traditionally, a stripe called the "boot top" is painted around the hull just above the waterline. In sailing boats, longer waterline length will usually enable a greater maximum speed, because it allows greater sail area, without increasing beam or d ...

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] |
Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scuttling Of The German Fleet In Scapa Flow
Shortly after the end of the First World War, the German Kaiserliche Marine was scuttled by its sailors while held off the harbor of the British Royal Navy base at Scapa Flow, in the Orkney Islands of Scotland. The High Seas Fleet was interned there under the terms of the Armistice while negotiations took place over the fate of the ships. Fearing that either the UK would seize the ships unilaterally or the German government at the time might reject the Treaty of Versailles and resume the war effort (in which case the ships could be used against Germany), Admiral Ludwig von Reuter decided to scuttle the fleet. The scuttling was carried out on 21 June 1919. Intervening British guard ships were able to beach some of the ships, but 52 of the 74 interned vessels sank. Many of the wrecks were salvaged over the next two decades and were towed away for scrapping. Those that remain are popular diving sites. The ships are a source of low-background steel.

Scapa Flow
Scapa Flow viewed from its eastern end in June 2009 Scapa Flow (; ) is a body of water in the Orkney Islands, Scotland, sheltered by the islands of Mainland, Graemsay, Burray,S. C. George, ''Jutland to Junkyard'', 1973. South Ronaldsay and Hoy. Its sheltered waters have played an important role in travel, trade and conflict throughout the centuries. Vikings anchored their longships in Scapa Flow more than a thousand years ago. It was the United Kingdom's chief naval base during the First and Second World Wars, but the facility was closed in 1956. Scapa Flow has a shallow sandy bottom not deeper than and most of it is about deep; it is one of the great natural harbours and anchorages of the world, with sufficient space to hold a number of navies. The harbour has an area of and contains just under 1 billion cubic metres of water. Since the scuttling of the German fleet after World War I, its wrecks and their marine habitats form an internationally acclaimed diving lo ...

Wilhelm Souchon
Wilhelm Anton Souchon (; 2 June 1864 – 13 January 1946) was a German admiral in World War I. Souchon commanded the ''Kaiserliche Marine''s Mediterranean squadron in the early days of the war. His initiatives played a major part in the entry of the Ottoman Empire into World War I. Biography Early life and career Wilhelm Anton Souchon was born on 2 June 1864 in Leipzig Saxony, to a family of Huguenot ancestry. His father was an artist and his mother the daughter of a Berlin banker. Souchon entered the Imperial German Naval Academy in 1881. After graduation he served on board the corvette ''Leipzig'' when it participated in the coastal colonisation of German South-West Africa in 1884. In 1884 Souchon, with the rank of Kapitän, had risen to command a training ship specialising in mine laying techniques. Between 1884 and 1903 Souchon progressed through several sea going and staff positions, reaching the rank of Korvettenkapitän in what was a steadily expanding navy. In 1904 ...
