Amphion-class Cruiser
The ''Leander'' class was a class of eight light cruisers built for the Royal Navy in the early 1930s that saw service in World War II. They were named after mythological figures, and all ships were commissioned between 1933 and 1936. The three ships of the second group were sold to the Royal Australian Navy (RAN) before World War II and renamed after Australian cities. Design The ''Leander'' class was influenced by the ''York''-class heavy cruiser and was an attempt to better provide for the role of commerce protection. The 7,000-7,200 ton ''Leander''s were armed with eight BL 6 inch Mk XXIII naval guns in twin turrets, two forward and two aft. Their secondary armament consisted of four high-angle QF 4 inch Mk V naval guns, which were later replaced by twin mountings for eight guns (the later high angle QF 4 inch Mk XVI naval gun). Their close-range anti-aircraft weaponry consisted of twelve Vickers machine guns in three quadruple mounts. They also shipped a bank of four to ...

Crane (machine)
A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy objects and transporting them to other places. The device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment. The first known crane machine was the shaduf, a water-lifting device that was invented in ancient Mesopotamia (modern Iraq) and then appeared in ancient Egyptian technology. Construction cranes later appeared in ancient Greece, where they were powered by men or animals (such as donkeys), and used for the construction of buildings. Larger cranes were later developed in the Roman Empire, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairey Seafox
The Fairey Seafox was a 1930s British reconnaissance floatplane designed and built by Fairey for the Fleet Air Arm. It was designed to be catapulted from the deck of a light cruiser and served in the Second World War. Sixty-six were built, with two finished without floats and used as landplanes. Design and development The Fairey Seafox was built to satisfy Air Ministry Specification S.11/32 for a two-seat spotter-reconnaissance floatplane. The first of two prototypes appeared in 1936, first flying on 27 May 1936,Taylor 1974, p.285. and the first of the 64 production aircraft were delivered in 1937.Taylor 1974, p.287. The flights were organised as 700 Naval Air Squadron of the Fleet Air Arm. The fuselage was of all-metal monocoque construction, the wings being covered with metal on the leading edge, otherwise fabric. It was powered by a 16-cylinder 395 hp (295 kW) air-cooled Napier Rapier H engine. It cruised at 106 mph (171 km/h), and had a range of 440 ...

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 ...

Vickers Machine Gun
The Vickers machine gun or Vickers gun is a Water cooling, water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The gun was operated by a three-man crew but typically required more men to move and operate it: one fired, one fed the ammunition, the others helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allies of World War I, Allied World War I fighter aircraft. The weapon had a reputation for great solidity and reliability. Ian V. Hogg, in ''Weapons & War Machines'', describes an action that took place in August 1916, during which the British 100th Company of the Machine Gun Corps fired their ten Vickers guns to deliver sustained fire for twelve hours. Using 100 barrels, they fired a million rounds without breakdowns. "It was this absolute foolproof reliability which endeared the Vickers to every Britis ...

QF 4 Inch Mk XVI Naval Gun
The QF 4 inch Mk XVI gunMk XVI = Mark 16. Britain used Roman numerals to denote marks (models) of ordnance until after World War II. Mark XVI indicates this was the sixteenth model of QF 4 inch gun. was the standard British Commonwealth naval anti-aircraft and dual-purpose gun of World War II. Service The Mk XVI superseded the earlier QF 4 inch Mk V naval gun on many Royal Naval ships during the late 1930s and early 1940s. The ammunition fired by the Mk V gun and the Mk XVI guns was different. The Mk V ammunition was long and weighed , while the ammunition fired by the Mk XVI gun was long and weighed . The weight of the high-explosive projectile grew from for the Mk V to for the Mk XVI. There were three variants of the gun produced with differing construction methods. The original Mk XVI had an A tube, jacket to from the muzzle and a removable breech ring. The Mk XVI* replaced the A tube with an autofretted loose barrel with a sealing collar at the front of the jacket. ... [...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] |
York-class Cruiser
The ''York'' class was the second and final class of heavy cruisers built for the Royal Navy under the terms of the 1922 Washington Naval Treaty. They were essentially a reduced version of the preceding , scaled down to enable more cruisers to be built from the limited defence budgets of the late 1920s. It was initially planned to build seven ships of this class, though in the end only two were constructed—, started in 1927, and , started in 1928. ''Exeter'' differed in appearance from ''York'' because of late changes in her design. The remaining ships were delayed due to budget cuts, and then following the London Naval Treaty of 1930 the Royal Navy decided its cruiser needs were best met by building a greater number of yet smaller cruisers with 6–in guns.Marriott, p. 35 While both ships served extensively in the first few years of the Second World War, it was ''Exeter'' that had the more notable career. ''Exeter'' took part in the Battle of the River Plate against the Germ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greek Mythology
A major branch of classical mythology, Greek mythology is the body of myths originally told by the Ancient Greece, ancient Greeks, and a genre of Ancient Greek folklore. These stories concern the Cosmogony, origin and Cosmology#Metaphysical cosmology, nature of the world, the lives and activities of List of Greek mythological figures, deities, Greek hero cult, heroes, and List of Greek mythological creatures, mythological creatures, and the origins and significance of the ancient Greeks' own cult (religious practice), cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of ancient Greece, and to better understand the nature of myth-making itself. The Greek myths were initially propagated in an oral tradition, oral-poetic tradition most likely by Minoan civilization, Minoan and Mycenaean Greece, Mycenaean singers starting in the 18th century BC; eventually the myths of the heroes of the Trojan War and its after ...
