HMS Cressy (1899)
HMS ''Cressy'' was a armoured cruiser built for the Royal Navy around 1900. Upon completion she was assigned to the China Station. In 1907 she was transferred to the North America and West Indies Station before being placed in reserve in 1909. Recommissioned at the start of World War I, she played a minor role in the Battle of Heligoland Bight a few weeks after the beginning of the war. ''Cressy'' and two of her sister ships were torpedoed and sunk by the German submarine ''U-9'' on 22 September 1914 with the loss of 560 of her crew. Design and description ''Cressy'' was designed to displace . The ship had an overall length of , a beam of and a deep draught of . She was powered by two 4-cylinder triple-expansion steam engines, each driving one shaft, which produced a total of and gave a maximum speed of . The engines were powered by 30 Belleville boilers. On her sea trials, ''Cressy'' only reached , the slowest performance of any of her class. She carried a maximum of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Crécy
The Battle of Crécy took place on 26 August 1346 in northern France between a French army commanded by King PhilipVI and an English army led by King EdwardIII. The French attacked the English while they were traversing northern France during the Hundred Years' War, resulting in an English victory and heavy loss of life among the French. The English army had landed in the Cotentin Peninsula on 12 July. It had burnt a path of destruction through some of the richest lands in France to within 2 miles (3 km) of Paris, sacking many towns on the way. The English then marched north, hoping to link up with an allied Flemish army which had invaded from Flanders. Hearing that the Flemish had turned back, and having temporarily outdistanced the pursuing French, Edward had his army prepare a defensive position on a hillside near Crécy-en-Ponthieu. Late on 26 August the French army, which greatly outnumbered the English, attacked. During a brief archery duel a large force of ...

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] |
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 ...

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 ...

Action Of 22 September 1914
The Action of 22 September 1914 was an attack by the German U-boat that took place during the First World War. Three obsolete Royal Navy cruisers, of the 7th Cruiser Squadron, manned mainly by Royal Naval Reserve part-time reservists and sometimes referred to as the Live Bait Squadron, were sunk by ''U-9'' while patrolling the southern North Sea. Neutral ships and trawlers nearby began to rescue survivors but 1,459 British sailors were killed. There was a public outcry in Britain at the losses. The sinkings eroded confidence in the British government and damaged the reputation of the Royal Navy, when many countries were still unsure about taking sides in the war. Background The cruisers were part of the Southern Force (Rear-Admiral Arthur Christian) composed of the flagship , the light cruiser and the 7th Cruiser Squadron (7th CS, also known as Cruiser Squadron C, Rear-Admiral H. H. Campbell, nicknamed the ''live-bait squadron''), comprising the armoured cruisers , , , and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Sister Ship
A sister ship is a ship of the same class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s, consisting of , and . As with some other liners, the sisters worked as running mates. Other sister ships include the Royal Caribbean International's and . ''Half-sister'' refers to a ship of the same class but with some s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Heligoland Bight (1914)
The Battle of Heligoland Bight was the first Anglo-German naval battle of the First World War, fought on 28 August 1914, between ships of the United Kingdom and Germany. The battle took place in the south-eastern North Sea, when the British attacked German patrols off the north-west German coast. The German High Seas Fleet was in harbour on the north German coast while the British Grand Fleet was out in the northern North Sea. Both sides engaged in long-distance sorties with cruisers and battlecruisers, with close reconnaissance of the area of sea near the German coast—the Heligoland Bight—by destroyer. The British devised a plan to ambush German destroyers on their daily patrols. A British flotilla of 31 destroyers and two cruisers under Commodore Reginald Tyrwhitt, with submarines commanded by Commodore Roger Keyes, was dispatched. They were supported at longer range by an additional six light cruisers commanded by William Goodenough and five battlecruisers commanded b ...

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reserve Fleet
A reserve fleet is a collection of naval vessels of all types that are fully equipped for service but are not currently needed; they are partially or fully decommissioned. A reserve fleet is informally said to be "in mothballs" or "mothballed"; an equivalent expression in unofficial modern US naval usage is "ghost fleet". In earlier times, especially in British usage, the ships were said to be "laid up in ordinary". Overview Such ships are held in reserve against a time when it may be necessary to call them back into service. They are usually tied up in backwater areas near naval bases or shipyards in order to speed the reactivation process. They may be modified for storage during such a period, for instance by having rust-prone areas sealed off or wrapped in plastic or, in the case of sailing warships, the masts removed. While being held in the reserve fleet, ships typically have a minimal crew (known informally as a skeleton crew) to ensure that they stay in somewhat usable co ...

North America And West Indies Station
The North America and West Indies Station was a formation or command of the United Kingdom's Royal Navy stationed in North American waters from 1745 to 1956. The North American Station was separate from the Jamaica Station until 1830 when the two combined to form the North America and West Indies Station. It was briefly abolished in 1907 before being restored in 1915. It was renamed the America and West Indies Station in 1926. It was commanded by Commanders-in-Chief whose titles changed with the changing of the formation's name, eventually by the Commander-in-Chief, America and West Indies Station. History The squadron was formed in 1745 to counter French forces in North America, with the headquarters at the Halifax Naval Yard in Nova Scotia (now CFB Halifax). The area of command had first been designated as the North American Station in 1767, under the command of Commodore Samuel Hood, with the headquarters in Halifax from 1758 to 1794, and thereafter in Halifax and Bermu ...

China Station
The Commander-in-Chief, China was the admiral in command of what was usually known as the China Station, at once both a British Royal Navy naval formation and its admiral in command. It was created in 1865 and deactivated in 1941. From 1831 to 1865, the East Indies Station and the China Station were a single command known as the East Indies and China Station. The China Station, established in 1865, had as its area of responsibility the coasts of China and its navigable rivers, the western part of the Pacific Ocean, and the waters around the Dutch East Indies. The navy often co-operated with British commercial interests in this area. The formation had bases at Singapore (Singapore Naval Base), HMS ''Tamar'' (1865–1941 and 1945–1997) in Hong Kong and Wei Hai (at Liugong Island) (1898–1940). The China Station complement usually consisted of several older light cruisers and destroyers, and the Chinese rivers were patrolled by a flotilla of suitable, shallow-draught gunboats, ...
