Oberon Class Submarine
The ''Oberon'' class was a ship class of 27 British-designed submarines operated by five different nations. They were designed as a direct follow-on from the ''Porpoise'' class: physical dimensions were the same, but stronger materials were used in hull construction, and updated equipment was fitted. The submarines were built between 1957 and 1978 by four shipyards: Cammell Laird (4), Chatham Dockyard (6), Scotts Shipbuilding and Engineering Company (11) and Vickers-Armstrongs (6). Thirteen of the submarines were operated by the Royal Navy, six by the Royal Australian Navy, three by the Brazilian Navy, three by the Royal Canadian Navy/Canadian Forces Maritime Command (plus two ex-Royal Navy boats later acquired for non-commissioned roles), and two by the Chilean Navy. The ''Oberon''s operated during the height of the Cold War, with duties including surveillance, tracking of other ships and submarines, delivery and retrieval of special forces personnel, and serving as targets f ...

Chilean Navy
The Chilean Navy ( es, Armada de Chile) is the naval warfare service branch of the Chilean Armed Forces. It is under the Ministry of National Defense. Its headquarters are at Edificio Armada de Chile, Valparaiso. History Origins and the Wars of Independence (1817–1830) The origins of the Chilean Navy date back to 1817, when General Bernardo O'Higgins prophetically declared after the Chilean victory at the Battle of Chacabuco that a hundred such victories would count for nothing if Chile did not gain control of the sea. This led to the development of the Chilean Navy, and the first legal resolutions outlining the organization of the institution were created. Chile's First National Fleet and the Academy for Young Midshipmen, which was the predecessor of the current Naval Academy, were founded, as well as the Marine Corps and the Supply Commissary. The first commander of the Chilean Navy was Manuel Blanco Encalada. Famous British naval commander Lord Cochrane, who for ...

Stonefish (mine)
Stonefish is a naval influence mine manufactured by British defence company BAE Systems. It has been exported to friendly countries such as Australia, which has both warstock and training versions of Stonefish. There has been conjecture that South Africa, Chile, Iraq, Libya and possibly other countries may have gained access to either some early Stonefish information or to similar technology. The mine is named after the venomous stonefish. Design Stonefish mines generally have two suspension lugs in order to facilitate handling operations e.g. winching. They can be deployed by fixed-wing aircraft, helicopters, surface vessels and submarines. It is a cylindrically shaped, modular weapon, comprising three separate sections which are joined together to form one unit: * launching system (e.g. nose fairing, tail-fin unit, parachute-pack and arming lanyards for air-dropped delivery) * electronics pack (incorporating safety/arming devices, target processing computer and associated fuz ...

Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individ ...

British 21 Inch Torpedo
There have been several British 21-inch (533 mm) torpedoes used by the Royal Navy since their first development just before the First World War. Torpedoes of 21 inch calibre were the largest torpedoes in common use in the RN. They were used by surface ships and submarines rather than aircraft, which used smaller 18-inch torpedoes. Mark I The first British 21-inch torpedo came in two lengths, "Short" at , and "Long" at . The explosive charge was of gun cotton increased later to . Mark II The Mark II, chiefly used by destroyers, entered service in 1914. Apart from some older British ships, it was used with the old US (destroyers-for-bases deal) Town-class destroyers provided to the UK during the early part of the Second World War. The running speed was reduced from (over 3,000 yards) for better reliability. The Mark II*, an improved Mark II, was used by battleships and battlecruisers. A wet heater design, it could run for at . Mark IV From 1912, used by destr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mark 24 Tigerfish
The Mark 24 Tigerfish was a heavyweight acoustic homing torpedo used by the Royal Navy (RN) during the 1980s and 90s. Conceptual development dates to the mid-1950s, and formally started in 1959 with a target introduction date in 1969. A lengthy development process led to a greatly reduced performance requirement, including the removal of anti-surface capabilities. The first prototype "Tiger Fish" examples were delivered in 1967. The Tigerfish was fitted with both active and passive sonar and could be remotely controlled through a thin wire which connected it to the launching submarine. Wire guidance permits a torpedo to be launched on-first-warning, i.e. when a target is first detected at long range. This permits the torpedo the time needed to close the range while target course and speed is being updated by the submarine's superior sensors and transmitted 'down-the-wire'. The torpedo can also be reassigned to another target or recalled. Typically, wire-guided torpedoes initially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Control Consoles - HMCS Onondaga
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The ''flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and property, atmospheric pollution, and water contamination. If fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scott Lithgow
Scott Lithgow, Limited was a Scottish shipbuilding company. History The Company was formed in 1967 by the merger of Scotts Shipbuilding and Engineering Company and Lithgows. Scott Lithgow was based in Port Glasgow and Greenock on the lower Clyde in Scotland. Scott Lithgow was nationalised and subsumed into British Shipbuilders in 1977. Reorganisation of Scott Lithgow in 1981 saw all the assets of its subsidiary companies transferred under the direct operational control of Scott Lithgow. From 1980, the company became the centre of British Shipbuilders’ Offshore Division and it was hoped that the offshore semi-submersible market would lead the yard back to profitability. However the ''Ocean Alliance'' semi-submersible construction was a disastrous contract for the company, with the rig eventually delivered four years late and at a loss of over £200 million.Scott Lithgow: Déjà vu all over again!

HMAS Onslow Fin And Masts
His Majesty's Australian Ship (HMAS) (or Her Majesty's Australian Ship when the monarch is female) is a ship prefix used for commissioned units of the Royal Australian Navy (RAN). This prefix is derived from HMS (Her/His Majesty's Ship), the prefix used by the Royal Navy of the United Kingdom, and can be equally applied to warships and shore bases (as Australia follows the British tradition of referring to naval establishments as stone frigates). On 10 July 1911, King George V granted the title of Royal Australian Navy to the naval forces of Australia. At the same time, the prefix and acronym were approved for use in identifying units commissioned into the RAN. The prefix had been used prior to formal approval, with the torpedo-boat destroyer In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casing (submarine)
The casing of a submarine is a light metal structure, usually incorporating a deck, built over the upper surface of the vessel's pressure hull. The pressure hull of a submarine is usually cylindrical and possesses a low freeboard when in the water, which makes walking on the hull when on the surface dangerous in high seas or rough weather. The casing provides a flat and therefore safer platform for personnel to walk on. The casing is outside the pressure hull and free-flooding so is usually perforated with numerous holes, allowing water to enter and trapped air to escape easily, eliminating any buoyancy contributed by the casing and allowing the submarine to submerge with as little delay as possible. Casings have been eliminated since the end of World War II as the flow of water through the numerous flood-holes creates noise that may be detected by an enemy using passive sonar, as well as causing hydrodynamic In physics and engineering, fluid dynamics is a subdiscipline ...
