Huangshan
Huangshan ( zh, s=黄山),Bernstein, pp. 125–127. literally meaning the Yellow Mountain(s), is a mountain range in southern Anhui province in eastern China. It was originally called "Yishan", and it was renamed because of a legend that Emperor Xuanyuan once made alchemy here. Vegetation on the range is thickest below , with trees growing up to the treeline at . The area is well known for its scenery, sunsets, peculiarly-shaped granite peaks, Huangshan pine trees, hot springs, winter snow and views of the clouds from above. Huangshan is a frequent subject of traditional Chinese paintings and literature, as well as modern photography. It is a UNESCO World Heritage Site and one of China's major tourist destinations. Physical description The Huangshan mountain range has many peaks, some more than 1,000 meters (3,250 feet) high.

Data Link
A data link is a means of telecommunications link, connecting one location to another for the purpose of transmitting and receiving digital information (data communication). It can also refer to a set of electronics assemblies, consisting of a transmitter and a receiver (two pieces of data terminal equipment) and the interconnecting data telecommunication circuit. These are governed by a link protocol enabling digital data to be transferred from a data source to a data sink. Types There are at least three types of basic data-link configurations that can be conceived of and used: * Simplex communications, most commonly meaning all communications in one direction only. * Half-duplex communications, meaning communications in both directions, but not both ways simultaneously. * Duplex (telecommunications), Duplex communications, communications in both directions simultaneously. Aviation In civil aviation, a data-link system (known as Controller Pilot Data Link Communications) is use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yu-7 Torpedo
The Yu-7 (; from , meaning ‘torpedo’) is a lightweight torpedo developed by the People's Republic of China. It entered service in the 1990s as the principal Anti-submarine warfare, 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, A244/S torpedo. Development Development of an effective lightweight Anti-submarine warfare, 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 engineering, reverse engineered from a United States Mark 46 torpedo, Mark 46 Mod 2 torpedo recovered from the South China Sea in 1978 by Chinese fishermen. Development was carried out by the 705th Institute (also known as Xi'an Precision Machinery Research Institute, 西安精密机械研究所). The torpedo was initially equipped with electric propul ...

C-803
The YJ-83 (; NATO reporting name: CSS-N-8 Saccade) is a Chinese subsonic anti-ship cruise missile. It is manufactured by the China Aerospace Science and Industry Corporation Third Academy. Development The YJ-83 uses microprocessors and a strap-down inertial reference unit (IRU); these are more compact than the equivalent electronics used in the YJ-8 and the export C-802, allowing the YJ-83 to have a 180-km range at Mach 0.9. The missile is powered by the Chinese CTJ-2 turbojet and is fitted with a 190-kg high-explosive fragmentation warhead. Terminal guidance is by an active radar. The air-launched YJ-83K has a range of , a cruise speed of Mach 0.9, and a high-explosive, semi-armour piercing warhead. The improved YJ-83KH uses a imaging-infrared seeker and has a range of 230 km; reportedly it may receive course corrections by remote link.

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 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 ...

HQ-16
The HQ-16 (; NATO reporting name: CH-SA-16) is a Chinese medium-range surface-to-air missile (SAM) developed by the Shanghai Academy of Spaceflight Technology (SAST) of China Aerospace Science and Technology Corporation (CASC). 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. Operational history The platform for the HHQ-16, the Type 054A frigate, entered service in 2008. The HQ-16A entered service in 2011. The HQ-16A entered Chinese service in 2011.

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 onto 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 missile launcher, Mark 13 single-arm and Mark 26 missile launcher, Mark 26 t ...

ELINT
Signals intelligence (SIGINT) is the act and field of 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). As classified and sensitive information is usually encrypted, signals intelligence may necessarily involve cryptanalysis (to decipher the messages). Traffic analysis—the study of who is signaling to whom and in what quantity—is also used to integrate information, and it may complement cryptanalysis. 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 transmissions. Since the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Countermeasures
An electronic countermeasure (ECM) is an electrical or electronic device designed to countermeasure, trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of Radar jamming, jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile guidance, missile terminal homers. History The first example of electronic countermeasures being a ...
