HMS Onyx (S21)
HMS ''Onyx'' was an ''Oberon'' class submarine of the Royal Navy. Design and construction The ''Oberon'' class was a direct follow on of the ''Porpoise''-class, with the same dimensions and external design, but updates to equipment and internal fittings, and a higher grade of steel used for fabrication of the pressure hull. As designed for British service, the ''Oberon''-class submarines were in length between perpendiculars and in length overall, with a beam of , and a draught of . Displacement was 1,610 tons standard, 2,030 tons full load when surfaced, and 2,410 tons full load when submerged. Propulsion machinery consisted of 2 Admiralty Standard Range 16 VMS diesel generators, and two electric motors, each driving a 3-bladed propeller at up to 400 rpm.

Cammell Laird
Cammell Laird is a British shipbuilding company. It was formed from the merger of Laird Brothers of Birkenhead and Johnson Cammell & Co of Sheffield at the turn of the twentieth century. The company also built railway rolling stock until 1929, when that side of the business was separated and became part of the Metro-Cammell, Metropolitan-Cammell Carriage & Wagon Company. History Formation from merger of Laird Company and Cammell & Co. The Laird Company was founded by William Laird (shipbuilder), William Laird, who had established the Birkenhead Iron Works in 1824. When he was joined by his son, John Laird (shipbuilder), John Laird in 1828, their first ship was an iron barge. John realised that the techniques of making boilers could be applied to making ships. The company soon became pre-eminent in the manufacture of iron ships and also made major advances in propulsion. In 1860, John Laird was joined in the business by his three sons, renaming the company John Laird, Sons & Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Argentine Air Forces In The Falklands War
This article describes the composition and actions of the Argentine air forces in the Falklands War ( es, Guerra de las Malvinas), which comprised units of the Air Force, Army, Navy and other services. For a description of air forces of the United Kingdom, see British air services in the Falklands War. Background Despite initiating the war, Argentina had not prepared a plan for the subsequent defence of the islands. The military dictatorship that governed the country at the time regarded the seizure of the Falklands as a political act to obtain a diplomatic bargaining position, and not as an act of war. Consequently they were taken by surprise when the British responded with a large-scale mobilization, and a task force to retake the islands. The Argentine Air Force (''Fuerza Aérea Argentina''; FAA), which had never fought against an external enemy since its establishment in 1912, had never considered the possibility of waging a long-range naval air campaign against a majo ...

RFA Sir Galahad (1966)
RFA ''Sir Galahad'' (L3005) was a Round Table class landing ship logistics ship, Round Table class landing ship logistics (LSL) vessel belonging to the Royal Fleet Auxiliary of the United Kingdom. The ship saw service in the Falklands War of 1982, where she was bombed and set afire at Fitzroy on 8 June. Background She was first managed for the British Army by the British-India Steam Navigation Company, before being transferred in 1970 to the RFA, and was manned by Hong Kong Chinese civilian crew. Design and construction The ''Sir Galahad'' was a 3,322-tonne LSL built by Alexander Stephen and Sons, Stephens and launched in 1966. She was built to merchant standards, which aided her destruction.

Exocet
The Exocet () is a French-built anti-ship missile whose various versions can be launched from surface vessels, submarines, helicopters and fixed-wing aircraft. Etymology The missile's name was given by M. Guillot, then the technical director at Nord Aviation. It is the French word for flying fish, from the Latin ''exocoetus'', a transliteration of the Greek name for the fish that sometimes flew into a boat: (''exōkoitos''), literally "lying down outside (, ), sleeping outside". Description The Exocet is built by MBDA, a European missile company. Development began in 1967 by Nord as a ship-launched weapon named the MM38. A few years later, Aerospatiale and Nord merged. The basic body design was based on the Nord AS-30 air-to-ground tactical missile. The sea-launched MM38 entered service in 1975, whilst the air-launched AM39 Exocet began development in 1974 and entered service with the French Navy five years later in 1979. The relatively compact missile is designed for at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Mikado
Operation Mikado was the code name of a military plan by the United Kingdom to use Special Air Service troops to attack the home base of Argentina's five Super Etendard strike fighters at Río Grande, Tierra del Fuego, during the 1982 Falklands War. Brigadier Peter de la Billière was in charge of planning the operation. The British Task Force had been successfully attacked by these Argentinian aircraft using French Exocet air-to-sea missiles, sinking two ships. This operation was intended to destroy the three remaining Exocet missiles that Argentina had in its possession as well as the Super Étendard launch aircraft. It was also intended to kill the pilots in their quarters. To achieve this, Brigadier Peter de la Billière ( Director of the SAS) proposed an operation similar to Operation Entebbe, which consisted of landing 55 SAS soldiers in two Lockheed C-130 Hercules aircraft directly on the runway at Rio Grande. According to the plan, the C-130s would be kept on the ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Skua
The Sea Skua is a British lightweight short-range air-to-surface missile (ASM) designed for use from helicopters against ships. It was primarily used by the Royal Navy on the Westland Lynx. Although the missile is intended for helicopter use, Kuwait employs it in a shore battery and on their ''Umm Al Maradem'' (Combattante BR-42) fast attack craft. The Royal Navy withdrew the missile from active service in 2017. Its replacement, Sea Venom, entered service in 2021. Development Sea Skua ultimately traces its history, indirectly, to the immediate post-war era. Growing increasingly concerned about the threat of aircraft, especially after the introduction of glide bombs during the war, the Royal Navy had long been convinced that all ships required some form of surface-to-air missile (SAM) for defence. These systems tended to be relatively large, especially in the era before vertical launch, and it was difficult to mount both a useful SAM and a conventional gun on smaller ships. Th ...

Magnetic Anomaly Detector
A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth's magnetic field. The term refers specifically to magnetometers used by military forces to detect submarines (a mass of ferromagnetic material creates a detectable disturbance in the magnetic field); military MAD equipment is a descendant of geomagnetic survey or aeromagnetic survey instruments used to search for minerals by detecting their disturbance of the normal earth-field. History Geoexploration by measuring and studying variations in the Earth's magnetic field has been conducted by scientists since 1843. The first uses of magnetometers were for the location of ore deposits. Thalen's "The Examination of Iron Ore Deposits by Magnetic Measurements", published in 1879, was the first scientific treatise describing this practical use. Magnetic anomaly detectors employed to detect submarines during World War II harnessed the fluxgate magnetometer, an inexpensive and easy to use t ...

Nautical Mile
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. Historically, it was defined as the meridian arc length corresponding to one minute ( of a degree) of latitude. Today the international nautical mile is defined as exactly . The derived unit of speed is the knot, one nautical mile per hour. Unit symbol There is no single internationally agreed symbol, with several symbols in use. * M is used as the abbreviation for the nautical mile by the International Hydrographic Organization. * NM is used by the International Civil Aviation Organization. * nmi is used by the Institute of Electrical and Electronics Engineers and the United States Government Publishing Office. * nm is a non-standard abbreviation used in many maritime applications and texts, including U.S. Government Coast Pilots and Sailing Directions. It conflicts with the SI symbol for nanometre. History The word mile is from the Latin word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grumman S-2 Tracker
The Grumman S-2 Tracker (S2F prior to 1962) was the first purpose-built, single airframe anti-submarine warfare (ASW) aircraft to enter service with the United States Navy. Designed and initially built by Grumman, the Tracker was of conventional design — propeller-driven with twin radial engines, a high wing that could be folded for storage on aircraft carriers, and tricycle undercarriage. The type was exported to a number of navies around the world. Introduced in 1952, the Tracker and its E-1 Tracer derivative saw service in the U.S. Navy until the mid-1970s, and its C-1 Trader derivative until the mid-1980s, with a few aircraft remaining in service with other air arms into the 21st century. Argentina and Brazil are the last countries to still use the Tracker. Design and development The Tracker was intended as a replacement for the Grumman AF Guardian, which was the first purpose-built aircraft system for ASW, using two airframes for two versions, one with the detecti ...
