HMS Holland 1
''Holland 1'' (or ''HM submarine Torpedo Boat No 1'') is the first submarine commissioned by the Royal Navy. The first in a six-boat batch of the , she was lost in 1913 while under tow to be scrapped following her decommissioning. Recovered in 1982, she was put on display at the Royal Navy Submarine Museum, Gosport. Her battery bank found in the boat was discovered to be functional after being cleaned and recharged. History She was ordered in 1901 from John Philip Holland and built at Barrow-in-Furness. Her keel was laid down 4 February 1901. In order to keep the boat’s construction secret, she was assembled in a building labelled "Yacht Shed", and the parts that had to be fabricated in the general yard were marked for "pontoon no 1". She was launched on 2 October 1901 and dived for the first time (in an enclosed basin) on 20 March 1902. Her sea trials began in April 1902. In September 1902 she arrived at Portsmouth, along with the other completed Holland boat and their ten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fenian Ram
''Fenian Ram'' is a submarine designed by John Philip Holland for use by the Fenian Brotherhood, the American counterpart to the Irish Republican Brotherhood, against the British. The Fenian Ram was the world’s first practical submarine, in that it was able to run on its own power using its 2-cylinder Brayton oil engine and dive & submerge successfully. The ''Ram'''s construction and launching in 1881 by the Delamater Iron Company in New York was funded by the Fenians' Skirmishing Fund. Officially ''Holland Boat No. II'', the role of the Fenians in its funding led the New York Sun newspaper to name the vessel the ''Fenian Ram''. Design ''Fenian Ram'''s design was partly modelled on the Whitehead torpedo, and it had similar cruciform control fins near the tail. The boat did not simply take on ballast until she sank like other contemporary submarines; she maintained a slightly positive buoyancy, and tilted her horizontal planes so that her forward motion forced her under.

John Philip Holland
John Philip Holland ( ga, Seán Pilib Ó hUallacháin/Ó Maolchalann) (24 February 184112 August 1914) was an Irish engineer who developed the first submarine to be formally commissioned by the US Navy, and the first Royal Navy submarine, ''Holland 1''.

Fibreglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo Tube On Holland 1
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/ submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though ...

Eddystone Lighthouse
The Eddystone Lighthouse is a lighthouse that is located on the dangerous Eddystone Rocks, south of Rame Head in Cornwall, England. The rocks are submerged below the surface of the sea and are composed of Precambrian gneiss. View at 1:50000 scale The current structure is the fourth to be built on the site. The first lighthouse (Winstanley's) was swept away in a powerful storm, killing its architect and five other men in the process. The second (Rudyard's) stood for fifty years before it burned down. The third (Smeaton's) is renowned because of its influence on lighthouse design and its importance in the development of concrete for building; its upper portions were re-erected in Plymouth as a monument. The first lighthouse, completed in 1699, was the world's first open ocean lighthouse, although the Cordouan Lighthouse off the western French coast preceded it as the first offshore lighthouse.

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 ...

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] |
Dogger Bank Incident
The Dogger Bank incident (also known as the North Sea Incident, the Russian Outrage or the Incident of Hull) occurred on the night of 21/22 October 1904, when the Baltic Fleet of the Imperial Russian Navy mistook a British trawler fleet from Kingston upon Hull in the Dogger Bank area of the North Sea for Imperial Japanese Navy torpedo boats and fired on them. Russian warships also fired on each other in the chaos of the melée. Two British fishermen died, six more were injured, one fishing vessel was sunk, and five more boats were damaged. On the Russian side, one sailor and a Russian Orthodox priest aboard the cruiser ''Aurora'' caught in the crossfire were killed. "Damage to the ''Aurora'' was concealed...and only discovered by the deciphering of a wireless message intercepted at he BritishFelixstowe station. It was also considered highly significant that no officer from that ship appeared before the Commission, nor were her logs produced." The incident almost led to wa ...

A-class Submarine (1903)
The A class was the Royal Navy's first class of British-designed submarines. Thirteen were built by Vickers at Barrow-in-Furness between 1902 and 1905 as an improvement on the US . Design and construction While there was considerable variation amongst the boats of the class, they were around long and displaced around 200 tons when submerged. The first, ''A1'' (ordered as ''Holland No. 6''), was launched in July 1902, the last, ''A13'', in April 1905. Propulsion All were propelled underwater by battery-powered electric motors and on the surface by shaft-drive Wolseley petrol engines of (''A1''), (''A2-A4'') or (''A5''-''A12''). ''A13'' had an experimental Vickers diesel engine, which proved to be unreliable. Armaments Armament was two torpedo tubes with four torpedoes except for ''A1'', which had 1 tube and 3 torpedoes. Service history This submarine class was plagued by numerous accidents and failures; almost every boat in the class (''A1'', ''A3'', ''A4'', ...

Reginald Bacon
Admiral Sir Reginald Hugh Spencer Bacon, (6 September 1863 – 9 June 1947) was an officer in the Royal Navy noted for his technical abilities. He was described by the First Sea Lord, Admiral Sir Jacky Fisher, as the man "acknowledged to be the cleverest officer in the Navy". Family Reginald was born at Wiggonholt in West Sussex, the son of the parish rector, Rev. Thomas Bacon, and his wife, Lavinia Emma, the daughter of George Shaw of Teignmouth in Devon. Rev. Thomas was the nephew of the industrialist, Anthony Bushby Bacon of Elcot Park in Berkshire and the grand-uncle of the historian, Emma Elizabeth Thoyts, of Sulhamstead House, also in Berkshire. Early career Reginald entered the Navy in 1877, qualified as a torpedo lieutenant, and first came to wider notice as commander of a flotilla of torpedo boats in the British naval manoeuvres of 1896. In 1897 he served as a member of the British punitive expedition to Benin, and on his return from active service wrote the book ''Be ...

Submarine Tender
A submarine tender is a type of depot ship that supplies and supports submarines. Development Submarines are small compared to most oceangoing vessels, and generally do not have the ability to carry large amounts of food, fuel, torpedoes, and other supplies, nor to carry a full array of maintenance equipment and personnel. The tender carries all these, and either meets submarines at sea to replenish them or provides these services while docked at a port near the area where the submarines are operating. In some navies, the tenders were equipped with workshops for maintenance, and as floating dormitories with relief crews. With the increased size and automation of modern submarines, plus in some navies the introduction of nuclear power, tenders are no longer as necessary for fuel as they once were. Canada Canada's first Submarine Depot Ship was . Chile The term used in the Chilean Navy is "submarine mother ship", as for example the BMS (buque madre de submarinos) ''Almirante M ...
