HMS Jamaica (C44)
HMS ''Jamaica'', a of the Royal Navy, was named after the island of Jamaica, which was a British Crown Colony when she was built in the late 1930s. The light cruiser spent almost her entire wartime career on Arctic convoy duties, except for a deployment south for the landings in North Africa in November 1942. She participated in the Battle of the Barents Sea in 1942 and the Battle of North Cape in 1943. ''Jamaica'' escorted several aircraft carriers in 1944 as they flew off airstrikes that attacked the in northern Norway. Late in the year she had an extensive refit to prepare her for service with the British Pacific Fleet, but the war ended before she reached the Pacific. ''Jamaica'' spent the late 1940s in the Far East and on the North America and West Indies Station. When the Korean War began in 1950 she was ordered, in cooperation with the United States Navy, to bombard North Korean troops as they advanced down the eastern coast. The ship also provided fire support d ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo#Classes and diameters, Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within t ...

Battle Of The Barents Sea
The Battle of the Barents Sea was a World War II naval engagement on 31 December 1942 between warships of the German Navy (''Kriegsmarine'') and British ships escorting convoy JW 51B to Kola Inlet in the USSR. The action took place in the Barents Sea north of North Cape, Norway. The German raiders' failure to inflict significant losses on the convoy infuriated Hitler, who ordered that German naval strategy would henceforth concentrate on the U-boat fleet rather than surface ships. Background JW 51B Convoy JW 51B comprised fourteen merchant ships carrying war materials to the USSR — some 202 tanks, 2,046 vehicles, 87 fighters, 33 bombers, of fuel, of aviation fuel and just over of other supplies. They were protected by the destroyers , , , , and ; the s and ; the minesweeper ; and trawlers and . The escort commander was Captain Robert Sherbrooke RN (flag in ''Onslow''). The convoy sailed in the dead of winter to preclude attacks by German aircraft, like those that d ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Operation Torch
Operation Torch (8 November 1942 – Run for Tunis, 16 November 1942) was an Allies of World War II, Allied invasion of French North Africa during the Second World War. Torch was a compromise operation that met the British objective of securing victory in North Africa while allowing American armed forces the opportunity to engage in the fight against Nazi Germany on a limited scale. It was the first mass involvement of US troops in the Mediterranean and Middle East theatre of World War II, European–North African Theatre, and saw the first major airborne assault carried out by the United States. While the French colonies were formally aligned with Germany via Vichy France, the loyalties of the population were mixed. Reports indicated that they might support the Allies. American General Dwight D. Eisenhower, supreme commander of the Allied forces in Mediterranean Theater of Operations, planned a three-pronged attack on Casablanca (Western), Oran (Center) and Algiers (Easter ...

Arctic Convoys Of World War II
The Arctic convoys of World War II were oceangoing convoys which sailed from the United Kingdom, Iceland, and North America to northern ports in the Soviet Union – primarily Arkhangelsk (Archangel) and Murmansk in Russia. There were 78 convoys between August 1941 and May 1945, sailing via several seas of the Atlantic and Arctic oceans, with two gaps with no sailings between July and September 1942, and March and November 1943. About 1,400 merchant ships delivered essential supplies to the Soviet Union under the Anglo-Soviet agreement and US Lend-Lease program, escorted by ships of the Royal Navy, Royal Canadian Navy, and the U.S. Navy. Eighty-five merchant vessels and 16 Royal Navy warships (two cruisers, six destroyers, eight other escort ships) were lost. Nazi Germany's '' Kriegsmarine'' lost a number of vessels including one battleship, three destroyers, 30 U-boats, and many aircraft. The convoys demonstrated the Allies' commitment to helping the Soviet Union, prior to the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Colony Of Jamaica
The Crown Colony of Jamaica and Dependencies was a British colony from 1655, when it was captured by the English Protectorate from the Spanish Empire. Jamaica became a British colony from 1707 and a Crown colony in 1866. The Colony was primarily used for sugarcane production, and experienced many slave rebellions over the course of British rule. Jamaica was granted independence in 1962. 17th century English conquest In late 1654, English leader Oliver Cromwell launched the ''Western Design'' armada against Spain's colonies in the Caribbean. In April 1655, General Robert Venables led the armada in an attack on Spain's fort at Santo Domingo, Hispaniola. However, the Spanish repulsed this poorly-executed attack, known as the Siege of Santo Domingo, and the English troops were soon decimated by disease. Weakened by fever and looking for an easy victory following their defeat at Santo Domingo, the English force then sailed for Jamaica, the only Spanish West Indies is ...

Island
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...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]   |

Hangar
A hangar is a building or structure designed to hold aircraft or spacecraft. Hangars are built of metal, wood, or concrete. The word ''hangar'' comes from Middle French ''hanghart'' ("enclosure near a house"), of Germanic origin, from Frankish *''haimgard'' ("home-enclosure", "fence around a group of houses"), from *''haim'' ("home, village, hamlet") and ''gard'' ("yard"). The term, ''gard'', comes from the Old Norse ''garðr'' ("enclosure, garden"). Hangars are used for protection from the weather, direct sunlight and for maintenance, repair, manufacture, assembly and storage of aircraft. History The Wright brothers stored and repaired their aircraft in a wooden hangar constructed in 1902 at Kill Devil Hills in North Carolina for their glider. After completing design and construction of the ''Wright Flyer'' in Ohio, the brothers returned to Kill Devil Hills only to find their hangar damaged. They repaired the structure and constructed a new workshop while they waited for th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Aircraft Catapult
An aircraft catapult is a device used to allow aircraft to take off from a very limited amount of space, such as the deck of a vessel, but can also be installed on land-based runways in rare cases. It is now most commonly used on aircraft carriers, as a form of assisted take off. In the form used on aircraft carriers the catapult consists of a track, or slot, built into the flight deck, below which is a large piston or ''shuttle'' that is attached through the track to the nose gear of the aircraft, or in some cases a wire rope, called a catapult bridle, is attached to the aircraft and the catapult shuttle. Other forms have been used historically, such as mounting a launching cart holding a seaplane on a long girder-built structure mounted on the deck of a warship or merchant vessel, but most catapults share a similar sliding track concept. Different means have been used to propel the catapult, such as weight and derrick, gunpowder, flywheel, air pressure, hydraulic, and steam ...

Seaplanes
A seaplane is a powered fixed-wing aircraft capable of takeoff, taking off and water landing, landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to Hydroplane (boat), motor-powered watercraft that use the technique of Planing (boat), hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplan ...

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]   |
