HMS Warrior (1905)
HMS ''Warrior'' was a armoured cruiser built for the Royal Navy in the first decade of the 20th century. She was stationed in the Mediterranean when the First World War began and participated in the pursuit of the German battlecruiser and light cruiser . ''Warrior'' was transferred to the Grand Fleet in December 1914 and remained there for the rest of her career. She was heavily damaged during the Battle of Jutland in 1916, after which she withdrew and was later abandoned and sank in a rising sea. Description ''Warrior'' displaced as built and fully loaded. The ship had an overall length of , a beam of and a draught of . She was powered by four-cylinder triple-expansion steam engines, driving two shafts, which developed a total of and gave a maximum speed of .Roberts, p. 34 The engines were powered by 19 Yarrow water-tube boilers and six cylindrical boilerss. The ship carried a maximum of of coal and an additional of fuel oil that was sprayed on the coal to in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Round Tower (Portsmouth)
The Round Tower is a fortification at the entrance to Portsmouth harbour. It is a Grade I listed building. History The site was originally occupied by a wooden tower before being replaced by a stone one. The wooden tower The wooden tower was built between 1418 and 1426 on the orders of King Henry V, or c1415. In 1422, a defensive chain that could be raised in an emergency was built from the round tower across the harbour entrance. The stone tower In the 1490s the tower was rebuilt in stone. In the 1680s a line of ramparts was added that connected the tower to the square tower. The upper section was later rebuilt during the Napoleonic wars. Between 1847 and 1850 the roof of the tower was modified to serve as a gun platform. Portsmouth city council purchased the tower in 1958. See also *Fortifications of Portsmouth The fortifications of Portsmouth are extensive due to its strategic position on the English Channel and role as home to the Royal Navy.

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] |
Draft (ship)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull Hull may refer to: Structures * Chassis, of an armored fighting vehicle * Fuselage, of an aircraft * Hull (botany), the outer covering of seeds * Hull (watercraft), the body or frame of a ship * Submarine hull Mathematics * Affine hull, in affi ..., and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are fro ...

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 repo ...

Warrior Class Cruiser Diagrams Brasseys 1912
A warrior is a person specializing in combat or warfare, especially within the context of a tribal or clan-based warrior culture society that recognizes a separate warrior aristocracies, class, or caste. History Warriors seem to have been present in the earliest pre-state societies. Scholars have argued that horse-riding Yamnaya warriors from the Pontic–Caspian steppe played a key role during the Indo-European migrations and the diffusion of Indo-European languages across Eurasia. Most of the basic weapons used by warriors appeared before the rise of most hierarchical systems. Bows and arrows, clubs, spears, swords, and other edged weapons were in widespread use. However, with the new findings of metallurgy, the aforementioned weapons had grown in effectiveness. When the first hierarchical systems evolved 5000 years ago, the gap between the rulers and the ruled had increased. Making war to extend the outreach of their territories, rulers often forced men from lower o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Fleet
The Grand Fleet was the main battlefleet of the Royal Navy during the First World War. It was established in August 1914 and disbanded in April 1919. Its main base was Scapa Flow in the Orkney Islands. History Formed in August 1914 from the First Fleet and part of the Second Fleet of the Home Fleets, the Grand Fleet included 25–35 modern capital ships. It was commanded initially by Admiral Sir John Jellicoe.Heathcote, p. 130 The 10th Cruiser Squadron carried out the Northern Patrol between the Shetlands and Norway and cruisers from Cromarty and Rosyth operated a second line (and screened the fleet) in enforcing the blockade of Germany. The administrative complications of the distant blockade across the northern exits of the North Sea overwhelmed the capacity of Vice Admiral Francis Miller, the Base Admiral in Chief from 7 August 1914, devolving on the commander in chief, Admiral John Jellicoe. To relieve the administrative burdens on Miller and Jellicoe, the post of the ... [...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 c ...

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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pursuit Of Goeben And Breslau
The pursuit of ''Goeben'' and ''Breslau'' was a naval action that occurred in the Mediterranean Sea at the outbreak of the First World War when elements of the British Mediterranean Fleet attempted to intercept the German '' Mittelmeerdivision'' consisting of the battlecruiser and the light cruiser . The German ships evaded the British fleet and passed through the Dardanelles to reach Constantinople, where they were eventually handed over to the Ottoman Empire. Renamed ''Yavuz Sultan Selim'' and ''Midilli'', the former ''Goeben'' and ''Breslau'' were ordered by their German commander to attack Russian positions, in doing so bringing the Ottoman Empire into the war on the side of the Central Powers. Though a bloodless "battle," the failure of the British pursuit had enormous political and military ramifications. In the short term it effectively ended the careers of the two British Admirals who had been in charge of the pursuit. Writing several years later, Winston Churchill—w ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was 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, 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 within the Ottoman Empire and in the 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 France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western Europe, Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological Evidences of the Antiquity of Man, Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from ...
