''Alaric'' was fitted with ten torpedo tubes, one QF 4 inch naval gun Mk XXIII, one Oerlikon 20 mm cannon, and a .303 British Vickers machine gun. Its torpedo tubes were fitted to the Bow (ship), b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Ensign Of The United Kingdom
The White Ensign, at one time called the St George's Ensign due to the simultaneous existence of a cross-less version of the flag, is an ensign worn on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field, identical to the flag of England except with the Union Flag in the upper canton. The White Ensign is also worn by yachts of members of the Royal Yacht Squadron and by ships of Trinity House escorting the reigning monarch. In addition to the United Kingdom, several other nations have variants of the White Ensign with their own national flags in the canton, with the St George's Cross sometimes being replaced by a naval badge omitting the cross altogether. Yachts of the Royal Irish Yacht Club wear a white ensign with an Irish tricolour in the first quadrant and defaced by the crowned harp from the Heraldic Badge of Ireland. The Flag of the British Antarctic Territory and the Commissioners' flag of the Northern Lighthouse Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
303 British
The .303 British (designated as the 303 British by the C.I.P. and SAAMI) or 7.7×56mmR, is a calibre rimmed rifle cartridge. The .303 inch bore diameter is measured between rifling lands as is the common practice in Europe which follows the traditional black powder convention. It was first manufactured in Britain as a stop-gap black powder round put into service in December 1888 for the Lee–Metford rifle. From 1891 the cartridge used smokeless powder which had been the intention from the outset, but the decision on which smokeless powder to adopt had been delayed. It was the standard British and Commonwealth military cartridge for rifles and machine guns from 1889 until the 1950s when it was replaced by the 7.62×51mm NATO. Cartridge specifications The .303 British has 3.64 ml (56 grains H2O) cartridge case capacity. The pronounced tapering exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns a ...

Cold War Submarines Of The United Kingdom
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero ...

Thos
Jackals are medium-sized canids native to Africa and Eurasia. While the word "jackal" has historically been used for many canines of the subtribe canina, in modern use it most commonly refers to three species: the closely related black-backed jackal (''Lupulella mesomelas'') and side-striped jackal (''Lupulella adusta'') of sub-Saharan-Africa, and the golden jackal (''Canis aureus'') of south-central Europe and Asia. The African golden wolf (''Canis lupaster'') was also formerly considered as a jackal. While they do not form a monophyletic clade, all jackals are opportunistic omnivores, predators of small to medium-sized animals and proficient scavengers. Their long legs and curved canine teeth are adapted for hunting small mammals, birds, and reptiles, and their large feet and fused leg bones give them a physique well-suited for long-distance running, capable of maintaining speeds of for extended periods of time. Jackals are crepuscular, most active at dawn and dusk. Their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coronation
A coronation is the act of placement or bestowal of a coronation crown, crown upon a monarch's head. The term also generally refers not only to the physical crowning but to the whole ceremony wherein the act of crowning occurs, along with the presentation of other items of regalia, marking the formal investiture of a monarch with regal power. Aside from the crowning, a coronation ceremony may comprise many other rituals such as the taking of special vows by the monarch, the investing and presentation of regalia to the monarch, and acts of homage by the new ruler's subjects and the performance of other ritual deeds of special significance to the particular nation. Western-style coronations have often included anointing the monarch with holy anointing oil, holy oil, or chrism as it is often called; the anointing ritual's religious significance follows examples found in the Bible. The monarch's consort may also be crowned, either simultaneously with the monarch or as a separate eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fleet Review
A fleet review or naval review is an event where a gathering of ships from a particular navy is paraded and reviewed by an incumbent head of state and/or other official civilian and military dignitaries. A number of national navies continue to hold fleet reviews. Fleet reviews may also include participants and warships from multiple navies. Commonwealth realms Fleet reviews in the Commonwealth realms are typically observed by the reigning monarch or their representative, a practice allegedly dating back to the 15th century. Such an event is not held at regular intervals and originally only occurred when the fleet was mobilised for war or for a show of strength to discourage potential enemies, or during periods of commemorations. Since the 19th century, they have often been held for the coronation or for special royal jubilees and increasingly included delegates from other national navies. Traditionally, a fleet review will have participating ships dressed in flags and pennants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow (ship)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ...

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 ...
