Type 42 Destroyer
The Type 42 or ''Sheffield'' class was a class of fourteen guided-missile destroyers that served in the Royal Navy.Marriott, Leo: ''Royal Navy Destroyers since 1945'', , Ian Allan Ltd, 1989 A further two ships of this class were built for and served with the Argentine Navy. The first ship of the class was ordered in 1968 and launched in 1971. Two of the class (''Sheffield'' and ''Coventry'') were lost to enemy action during the Falklands War of 1982. The Royal Navy used this class of destroyer for 38 years between 1975 and 2013. No ships of this class remain active in the Royal Navy and both have also been retired from the Argentine Navy. The Royal Navy has replaced them with Type 45 destroyers. History The class was designed in the late 1960s to provide fleet area air defence. In total fourteen vessels were constructed in three batches. In addition to the Royal Navy ships, two more ships were built to the same specifications as the Batch 1 vessels for the Argentine Navy. ...

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 aircraft, 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, 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 somet ...

Strake
On a vessel's Hull (watercraft), hull, a strake is a longitudinal course of Plank (wood), planking or Plate (metal), plating which runs from the boat's stem (ship), stempost (at the Bow (ship), bows) to the stern, sternpost or transom (nautical), transom (at the rear). The garboard strakes are the two immediately adjacent to the keel on each side. The word derives from traditional wooden boat building methods, used in both Carvel (boat building), carvel and clinker (boat building), clinker construction. In a metal ship, a strake is a course of plating. Construction In small boats strakes may be single continuous pieces of wood. In larger wooden vessels strakes typically comprise several planks which are either scarf joint, scarfed, or Butt joint, butt-jointed and reinforced with a butt block. Where the transverse sections of the vessel's shape are fuller, the strakes are wider; they taper toward the ends. In a Rivet, riveted steel ship, the strakes were usually lapped and ...

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in the older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involve a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Deck
The flight deck of an aircraft carrier is the surface on which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships". Flight decks have been in use upon ships since 1910, the American pilot Eugene Ely being the first individual to take off from a warship. Initially consisting of wooden ramps built over the forecastle of capital ships, a number of battlecruisers, including the British and , the American and , and the Japanese ''Akagi'' and battleship ''Kaga'', were converted to aircraft carriers during the interwar period. The first aircraft carrier to feature a full-length flight deck, akin to the configuration of the modern vessels, was the converted liner which entered service in 1918. The armoured flight deck was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground or the sea to destroy aircraft or other missiles. It is one type of anti-aircraft warfare, anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. T ...

Sea Dart
Sea Dart, or GWS.30 was a Royal Navy surface-to-air missile system designed in the 1960s and entering service in 1973. It was fitted to the Type 42 destroyers, the single Type 82 destroyer and the s. Originally developed by Hawker Siddeley, the missile was built by British Aerospace after 1977. It was withdrawn from service in 2012. Britain's first naval surface-to-air missile was GWS1 Seaslug, which entered service in 1963. This used beam riding guidance which offered limited accuracy and was useful only against slower targets. The need for a higher performance system was seen even as it entered service. Bristol Aerospace, which had recently introduced the ramjet-powered Bloodhound missile for the RAF, offered a new ramjet powered concept, while British Aircraft Corporation (BAC) proposed a shorter-range rocket powered design. The Admiralty asked for a proposal combining BAC's layout with Bristol's engine, which became Sea Dart. Compared to Seaslug, Sea Dart was faster, h ...

CVA-01
CVA-01 was a proposed United Kingdom aircraft carrier, designed during the 1960s. The ship was intended to be the first of a class that would replace all of the Royal Navy's carriers, most of which had been designed before or during the Second World War. CVA-01 and CVA-02 were intended to replace and , while CVA-03 and CVA-04 would have replaced and respectively. The planned four carrier class was soon reduced to three before further being reduced to two until finally, following a government review in the form of the 1966 Defence White Paper, the project was cancelled - along with the proposed Type 82 destroyer class, which were intended primarily as escorts for carrier groups. Factors contributing to the cancellation of CVA-01 included inter-service rivalries, the huge financial costs of the proposed carrier against ongoing budgetary constraints, and the technical complexity and difficulties it would have presented in construction, operation, and maintenance.

Navy Of The Argentine Republic
The Argentine Navy (ARA; ). This forms the basis for the navy's ship prefix "ARA". is the navy of Argentina. It is one of the three branches of the Armed Forces of the Argentine Republic, together with the Army and the Air Force. The Argentine Navy day is celebrated on May 17, anniversary of the victory in 1814 at the Battle of Montevideo over the Spanish fleet during the war of Independence. History 1810–1909 The Argentine Navy was created in the aftermath of the May Revolution of May 25, 1810, which started the war for independence from Spain. The navy was first created to support Manuel Belgrano in the Paraguay campaign, but those ships were sunk by ships from Montevideo, and did not take part in that conflict. Renewed conflicts with Montevideo led to the creation of a second fleet, which participated in the capture of the city. As Buenos Aires had little maritime history, most men in the navy were from other nations, such as the Irish-born admiral William Brown, who ...
