Yancheng
Yancheng () is a prefecture-level city in northeastern Jiangsu province of China, province, People's Republic of China. As the city with the largest jurisdictional area in Jiangsu, Yancheng borders Lianyungang to the north, Huai'an to the west, Yangzhou and Taizhou, Jiangsu, Taizhou to the southwest, Nantong to the south, and the Yellow Sea to the east. Formerly a county, the current Yancheng city was founded on January 18, 1983. Yancheng, literally "Salt City", is named after the sea salt, salt harvest fields surrounding the city. According to historical records, collection and production of sea salt in the region began as early as 119 BC, during the Western Han Dynasty, when the settlement on the current location of Yancheng was named Yandu County ().

Link 11
TADIL-A/Link 11 is a secure half-duplex tactical data link used by NATO to exchange digital data. It was originally developed by a joint committee including members from the Canadian Navy, US Navy and Royal Navy to pass accurate targeting information between ships. The final standard was signed in Ottawa in November 1957, where the British proposed the name "TIDE" for "Tactical International Data Exchange". It was later made part of the NATO STANAG standardization process. The system operates on two frequencies, one in the high frequency (HF) range for over-the-horizon (OTH) communications, and another in the ultra high frequency (UHF) range that uses much smaller antennas and is suitable for smaller ships but lacks the OTH performance. The system broadcasts packets of 30 bits length, with 6 bits of error correction and 24 bits of payload data. The payload is encrypted. Link 14 was adopted at the same time as a low-end counterpart to Link 11. Link 14 is essentially a digital te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-submarine Warfare
Anti-submarine warfare (ASW, or in 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 involved 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 instan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yu-7 Torpedo
The Yu-7 (; from ) is a lightweight torpedo developed by the People's Republic of China. It entered service in the 1990s as the principal anti-submarine weapon of major People's Liberation Army Navy (PLAN) warships. The Yu-7 is a derivative of the Whitehead Alenia Sistemi Subacquei (WASS) A244/S torpedo. Development Development of an effective lightweight anti-submarine (ASW) torpedo for the PLAN began in the 1980s. The program was probably based on 40 A244/S torpedoes purchased for evaluation from Italy in 1987. Additional technology may have been reverse engineered from a United States Mark 46 Mod 2 torpedo recovered from the South China Sea in 1978 by Chinese fishermen. The torpedo was initially equipped with electric propulsion, but inadequate performance led to a redesign powered by Otto fuel II. Testing was carried out at the 750 Testing Range in Kunming up to 1988. Description The Yu-7 has contrarotating propellers. Aboard surface warships, it is fired from Type 7424 tr ...

CY-1
The CY-1 (Chang Ying 长缨, ''Long Tassel'', often erroneously referred as ''Chian Yu'', 剑鱼, or ''Swordfish'') is a People's Republic of China, Chinese ASROC, anti-submarine rocket carried on a variety of surface platforms, including the Type 051 destroyer, Luda class missile destroyers and Type 053H3 frigate, Jiangwei class missile frigates. A series of CY ASW missiles have been developed based on CY-1. To date only a small number of CY-1 is known to have been produced and deployed on trial basis, despite the fact that it had first appeared on the defense exhibitions held in China in the late 1980s. CY-1 The CY-1 is believed to similar in operation to the United States Navy, U.S. Navy ASROC. There is little information available regarding the development history, performance, and exact status of the missile, but it is understood that a few of the missiles were deployed on the People's Liberation Army Navy, PLA Navy Type 051 (Luda class) destroyers and Type 052H2G (Jiangwei-I ...

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] |
HQ-16
The HQ-16 () is a medium-range surface-to-air missile (SAM) from the People's Republic of China. It is derived from earlier versions of the Russian Buk missile system. Development Development began in 2005, and was reportedly assisted by the Almaz-Antey Corporation. It was initially developed as a naval system. In late-2011, China reported the "co-development between Russia and China" of the missile was complete. The HQ-16B was developed by late-2011. A ground battery consists of a command post, two multifunction radars, and four to six launchers. Each launcher has six missiles.

Vertical Launching System
A vertical launching system (VLS) is an advanced system for holding and firing missiles on mobile naval platforms, such as surface ships and submarines. Each vertical launch system consists of a number of ''cells'', which can hold one or more missiles ready for firing. Typically, each cell can hold a number of different types of missiles, allowing the ship flexibility to load the best set for any given mission. Further, when new missiles are developed, they are typically fitted to the existing vertical launch systems of that nation, allowing existing ships to use new types of missiles without expensive rework. When the command is given, the missile flies straight up far enough to clear the cell and the ship, then turns on to the desired course. A VLS allows surface combatants to have a greater number of weapons ready for firing at any given time compared to older launching systems such as the Mark 13 single-arm and Mark 26 twin-arm launchers, which were fed from behind by a ...

ELINT
Signals intelligence (SIGINT) is intelligence-gathering by interception of ''signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). Signals intelligence is a subset of intelligence collection management. As classified and sensitive information is usually encrypted, signals intelligence in turn involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signaling whom and in what quantity—is also used to integrate information again. History Origins Electronic interceptions appeared as early as 1900, during the Boer War of 1899–1902. The British Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s, and the British Army used some limited wireless signalling. The Boers captured some wireless sets and used them to make vital transmis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
