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] |
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 to destroy aircraft or other missiles. It is one type of 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. This evolution of design increasin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elizabeth II
Elizabeth II (Elizabeth Alexandra Mary; 21 April 1926 – 8 September 2022) was Queen of the United Kingdom and other Commonwealth realms from 6 February 1952 until her death in 2022. She was queen regnant of 32 sovereign states during her lifetime, and was head of state of 15 realms at the time of her death. Her reign of 70 years and 214 days was the longest of any British monarch and the longest verified reign of any female monarch in history. Elizabeth was born in Mayfair, London, as the first child of the Duke and Duchess of York (later King George VI and Queen Elizabeth The Queen Mother). Her father acceded to the throne in 1936 upon the abdication of his brother Edward VIII, making the ten-year-old Princess Elizabeth the heir presumptive. She was educated privately at home and began to undertake public duties during the Second World War, serving in the Auxiliary Territorial Service. In November 1947, she married Philip Mountbatten, a former prince ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beira Patrol
The Beira Patrol was a blockade of oil shipments to Rhodesia (now Zimbabwe) through Beira, Mozambique, resulting from United Nations trade sanctions on Rhodesia. Background Rhodesia's government unilaterally declared the former colony's independence on 11 November 1965, after rejecting British preconditions for independence that involved racial equality and rule by the black majority. Ian Smith, the country's elected prime minister, continued in that role. The United Nations Security Council reacted by passing Resolution 217, calling for sanctions on Rhodesia. The resolution was later used by the British as legal justification for the blockade. Britain imposed its own national sanctions, including an oil embargo, but ruled out invading Rhodesia. The British were initially opposed to military action, instead relying on UN sanctions to pressure the Rhodesians. A majority of UN member states wanted expanded sanctions and military measures. The British initially attempted to blo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isle Of Portland
An isle is an island, land surrounded by water. The term is very common in British English. However, there is no clear agreement on what makes an island an isle or its difference, so they are considered synonyms. Isle may refer to: Geography * Isle (river), a river in France * Isle, Haute-Vienne, a commune of the Haute-Vienne ''département'' in France * Isle, Minnesota, a small city in the United States * River Isle, a river in England Arts, entertainment, and media * ''Interdisciplinary Studies in Literature and Environment'' (or ''ISLE''), a journal published by Oxford University Press for the Association for the Study of Literature and Environment *''The Isle'', 2017 film with Conleth Hill * ''The Isle'', a 2000 South Korean film directed by Kim Ki-duk * ''Isle'' (album) Other uses * International Society for the Linguistics of English (ISLE), a learned society of linguists See also * Aisle An aisle is, in general, a space for walking with rows of non-walking spaces o ...

Far East Fleet
The Far East Fleet (also called the Far East Station) was a fleet of the Royal Navy which existed between 1952 and 1971. During the Second World War, the Eastern Fleet included many ships and personnel from other navies, including those of the Netherlands, Australia, New Zealand, and the United States. On 22 November 1944 the Eastern Fleet was re-designated East Indies fleet and continued to be based in Trincomalee. Following its re-designation its remaining ships formed the British Pacific Fleet. In December 1945 the British Pacific Fleet was disbanded and its forces were absorbed into the East Indies Fleet. In 1952 The East Indies Fleet was renamed the Far East Fleet. After the Second World War the East Indies Station continued as a separate command to the Far East until 1958. In 1971 the Far East Fleet was abolished and its remaining forces returned home, coming under the command of the new, unified, Commander-in-Chief Fleet. Post-war After the war, the East Indies Fleet wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable Depth Sonar
A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. Trailing the hydrophones behind the vessel, on a cable that can be kilometers long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting and tracking faint contacts, such as quiet, low noise-emitting submarine threats, or seismic signals. A towed array offers superior resolution and range compared with hull mounted sonar. It also covers the baffles, the blind spot of hull mounted sonar. However, effective use of the system limits a vessel's speed and care must be taken to protect the cable from damage. History During World War I, a towed sonar array known as the "Electric Eel" was developed by Harvey Hayes, a U.S. Navy physicist. This system is believed to be the first towed sonar array design. It employed two cables, each with a dozen hydrophones attached. The project was discontin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...
