Zhongjian River
Triton Island (; ) is the westernmost and southernmost of the Paracel Islands in the South China Sea. It is located on the southwest corner of Triton Reef and has an area of above sea-level. The reef including the island measures about in area. The island is administered by the People's Republic of China, and is also claimed by the Republic of China (Taiwan) and Vietnam. The island was historically known by the Chinese as ''Bànlù Zhì'' (), and as ''Luó Dǎo'' () to Chinese fishermen. Other Chinese sources have it named as 南建岛, as it was the southernmost point claimed by China until after 1933. The current Chinese name commemorates the Republic of China Navy warship ''ROCS Chung-chien'' () sent in 1946 to claim the Paracel Islands. History Lacking a native population, ownership of the Paracel Islands has been disputed since the early 20th century. In the aftermath of the First Indochina War, until 1974 Vietnam occupied Pattle Island, approximately northeast. Control ...

South China Sea
The South China Sea is a marginal sea of the Western Pacific Ocean. It is bounded in the north by South China, in the west by the Indochinese Peninsula, in the east by the islands of Taiwan island, Taiwan and northwestern Philippines (mainly Luzon, Mindoro and Palawan Island, Palawan), and in the south by Borneo, eastern Sumatra and the Bangka Belitung Islands, encompassing an area of around . It communicates with the East China Sea via the Taiwan Strait, the Philippine Sea via the Luzon Strait, the Sulu Sea via the straits around Palawan, the Java Sea via the Karimata Strait, Karimata and Bangka Straits and directly with Gulf of Thailand. The Gulf of Tonkin is part of the South China Sea. $3.4 trillion of the world's $16 trillion Maritime transport, maritime shipping passed through South China Sea in 2016. Oil and natural gas reserves have been found in the area. The Western Central Pacific accounted for 14% of world's commercial fishing in 2010. The South China Sea Islands, ...

Synthetic-aperture Radar
Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars. SAR is typically mounted on a moving platform, such as an aircraft or spacecraft, and has its origins in an advanced form of side looking airborne radar (SLAR). The distance the SAR device travels over a target during the period when the target scene is illuminated creates the large ''synthetic'' antenna aperture (the ''size'' of the antenna). Typically, the larger the aperture, the higher the image resolution will be, regardless of whether the aperture is physical (a large antenna) or synthetic (a moving antenna) – this allows SAR to create high-resolution images with comparatively small physical antennas. For a fixed antenna size and orientation, objects which are ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Guided Missile Destroyer
A guided-missile destroyer (DDG) is a destroyer whose primary armament is guided missiles so they can provide anti-aircraft warfare screening for the fleet. The NATO standard designation for these vessels is DDG, while destroyers which have a primary gun armament or a small number of anti-aircraft missiles sufficient only for point-defense are designated DD. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether. Guided-missile destroyers are equipped with large missile magazines, with modern examples typically having vertical-launch cells. Some contain integrated weapons systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true for navies that no longer operate cruisers, so other vessels must be adopted to fill in the gap. Many guided-missile destroyers are also multipurpose vessels, equipped to ca ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Freedom Of Navigation
Freedom of navigation (FON) is a principle of law of the sea that ships flying the flag of any sovereign state shall not suffer interference from other states when in international waters, apart from the exceptions provided for in international law. In the realm of international law, it has been defined as “freedom of movement for vessels, freedom to enter ports and to make use of plant and docks, to load and unload goods and to transport goods and passengers". This right is now also codified as Article 87(1)a of the 1982 United Nations Convention on the Law of the Sea. History Development as a legal concept Freedom of navigation as a legal and normative concept has developed only relatively recently. Until the early modern period, international maritime law was governed by customs that differed across countries’ legal systems and were only sometimes codified, as for example in the 14th-century Crown of Aragon ''Consulate of the Sea'' (; ; also known in English as the ''C ...

The Pentagon
The Pentagon is the headquarters building of the United States Department of Defense, in Arlington County, Virginia, across the Potomac River from Washington, D.C. The building was constructed on an accelerated schedule during World War II. As a symbol of the United States Armed Forces, U.S. military, the phrase ''The Pentagon'' is often used as a metonym for the Department of Defense and its leadership. The building was designed by American architect George Bergstrom and built by contractor John McShain. Ground was broken on 11 September 1941, and the building was dedicated on 15 January 1943. General Brehon Somervell provided the major impetus to gain Congressional approval for the project. Colonel Leslie Groves was responsible for overseeing the project for the United States Army Corps of Engineers, U.S. Army Corps of Engineers, which supervised it. The Pentagon is List of largest office buildings, the world's second-largest office building, with about of floor space, of ...

12 Mile Limit
Territorial waters are informally an area of water where a sovereign state has jurisdiction, including internal waters, the territorial sea, the contiguous zone, the exclusive economic zone, and potentially the extended continental shelf (these components are sometimes collectively called the maritime zones). In a narrower sense, the term is often used as a synonym for the territorial sea. Vessels have different rights and duties when passing through each area defined by the United Nations Convention on the Law of the Sea (UNCLOS), one of the most ratified treaties. States cannot exercise their jurisdiction in waters beyond the exclusive economic zone, which are known as the high seas. Baseline Normally, the baseline is the low-water line along the coast as marked on large-scale charts that the coastal state recognizes. This is either the low-water mark closest to the shore or an unlimited distance from permanently exposed land, provided that some portion of elevations exp ...

The Guardian
''The Guardian'' is a British daily newspaper. It was founded in Manchester in 1821 as ''The Manchester Guardian'' and changed its name in 1959, followed by a move to London. Along with its sister paper, ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust Limited. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in its journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. S ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Stealth Aircraft
Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio frequency (RF) spectrum, and audio, collectively known as stealth technology. The F-117 Nighthawk was the first operational aircraft explicitly designed around stealth technology. Other examples of stealth aircraft include the Northrop Grumman B-2 Spirit, B-2 Spirit, the B-21 Raider, the Lockheed Martin F-22 Raptor, F-22 Raptor, the F-35 Lightning II, the Chengdu J-20, and the Sukhoi Su-57. While no aircraft is completely invisible to radar, stealth aircraft make it more difficult for conventional radar to detect or track the aircraft effectively, increasing the odds of an aircraft avoiding detection by enemy radar and/or avoiding being successfully targeted by Semi-active radar guidance, radar guided weapons. Stealth is a combination of passive low observable (LO) features and active emitters such as low-probability-of-interc ...

USNS Sgt
United States Naval Ship (USNS) is the prefix designation given to non- commissioned ships that are property of the United States Navy (USN). Definition United States Naval Ships are unarmed auxiliary support vessels owned by the U.S. Navy and operated in non-commissioned service by Military Sealift Command with a civilian crew. Some ships include a small military complement to carry out communication and special mission functions, or for force protection. In comparison, U.S. Navy ships commissioned into military service have the designation " USS", are armed, and are crewed by U.S. Navy personnel. Additionally, the United States Naval Ships hull classification symbol begins with "T-" to denote its civilian crew. The USNS prefix can be assigned only while the ship is owned by the U.S. Navy. If, after being taken out of service, the ship is transferred to the Maritime Administration the prefix reverts to a civilian ship prefix such as the case of SS ''Comet''. See also ...

Battle Of The Paracel Islands
The Battle of the Paracel Islands (Chinese: 西沙海战 (pinyin Xisha haizhan);Vietnamese: Hải chiến Hoàng Sa) was an engagement between the Chinese and South Vietnamese navies near the Paracel Islands on January 19, 1974. The battle was part of an attempt by the South Vietnamese navy to remove the Chinese navy from the area towards the end of the Vietnam War. Prior to the conflict, part of the Paracel Islands was controlled by China and another part was controlled by South Vietnam. The battle resulted in a victory for China over South Vietnam. Consequently, China occupied the portion formerly controlled by South Vietnam and established full ''de facto'' control over the Paracels. Background Confrontation in the Paracels The Paracels are in the South China Sea approximately 300 kilometers south of China and 370 kilometers east Vietnam. The islands are divided into the northern Amphitrite Group, and the Crescent Group 80 kilometers to the southwest. The islands ...
