[air force the world's original] in June this year, the western media reportsChina has already begun to build huge underwater monitoring and operational network.

This network will eventually cover Bohai, the Yellow Sea, East China Sea and the South China Sea waters, the formation of a complete protection of the coastal waters of China's underwater reconnaissance and defense combat system.

This report, the first from the Western submarine analysis of the blog peace". The blog said, China this "underwater the Great Wall" has completed the first phase of the construction.

The blog said that the first phase of China's underwater the Great Wall includes the following major regional nodes:

• Bohai Huludao node

• The Yellow Sea Dalian node

• The Yellow Sea Qingdao node

• Shanghai East China Sea node

• Yalong Bay surrounding naval base as the core of the South China Sea node

[original] the world air force Gatlin media that the foundation of the network from the former Soviet Union countries Chinese technology introduction, after a thorough improvement and development of scientific research institutions and military China, finally began the first phase of construction in 1996. To 2012, has begun to take shape. Chinese underwater basic concept of the Great Wall is very simple, hydrophone, magnetic anomaly detector which is composed of a large number of connected together through the communication network as the main means of reconnaissance, detection and tracking of the network coverage of submarines and surface ships. China system with the United States corresponding to a large difference between water network, is to increase the combat means of attack, this year some standby, under water system capable of autonomous or remote control operations have long-term exposure, they make China underwater the Great Wall not only can detect tracking, can also destroy enemy targets. With the support of the anti submarine ship has a huge water, air force platform construction, such as large fixed wing aircraft of the latest development of the equipment.

The analysis of the article believes that the main node of China's underwater the Great Wall is closely related to the naval base in the following sketch map.

According to the letter China naval and military research institutions before the introduction of the former Soviet Union, the US "Su Texas" underwater sound monitoring system (SOSUS) showed a keen interest in this paper a lot of research. There have been a lot of engineering design papers about underwater monitoring network in the technical journals of hydrology and other academic fields.

This paper reveals some important features of China related network technology, such as China underwater parts of the Great Wall using existing facilities based hydrological monitoring system, and built military surveillance network, civilian technology and equipment have also been added to the network, making the water under the the Great Wall became a dual-use, highly integrated system. Wireless secure transmission has been more applications, breaking the shackles of the wired communication means in the relevant network. In the wake of the sleeping and waking mode of the related equipment, the energy saving problem of the independent or mobile device is solved.

Technology and equipment of another amazing, is the "mobile underwater monitoring equipment". Almost all of the known monitoring equipment is a fixed - mounted hydrophone or magnetic anomaly detector, but China has developed a monitoring device that can move under water. This not only means that China this network can according to the needs of mobile surveillance equipment, the formation of more suitable for the specific needs of the monitoring network, also means that the equipment survivability will be an unprecedented increase, make each other difficulty greatly destroy the equipment increase. If these devices can move a long distance, and may even lead to the other side can not destroy a larger area of the monitoring network, because the search and positioning of the workload will show the amount of the increase in the number of. In addition, mobile devices and wireless communication means, the part of the monitoring equipment can to maneuver to safer waters, and then go up to the depth for wireless communications, high-speed data transmission and other devices or core nodes, the network node and command communication system more convenient and reliable, anti blow.

[air force the world's original] in 2013, the China Science and technology daily announced the existence of the "China deep-sea submarine detection network" in. Report mainly describes the "Tianlong" expedition ship implementation of the submarine monitoring equipment layout and recovery work in the central basin of the South China Sea, points out the related work to establish a covering almost the entire South China Sea waters in the South China Sea central monitoring network. Although this project is not equivalent to the Chinese military underwater monitoring network, but its technical principle there is not a fraction of difference. Part of the monitoring equipment was deployed in the depths of 4000 meters of water, which means that China has fully mastered the ability to monitor the network in the offshore deepwater area.

More worthy of note, active defense and offensive weapons and equipment in this system, the enemy submarine strangling the throat, change the balance of power in the coastal waters of Chinese.

For example, in the near future China's underwater surveillance tool: "Sea Wing" underwater glider, is a kind of underwater mobile robot with the ability to detect and attack.

This robot is similar to the appearance of the torpedo, but by the installation of a number of wing surface, the robot is more powerful than the torpedo. "Sea Wing" number can work in the depth of 1000 meters, life is amazing one thousand kilometers, almost 20 times the torpedo. At present, this robot has been put into active use.

Once China has built up the coastal waters of the the Great Wall, the eyes will be placed in the vast Pacific Ocean. The most successful submarine sonar reconnaissance system, is the "Su Texas" system, its original purpose is the defense of the Soviet Union naval vessels. "Su Texas" is divided into two parts, one part is composed of thousands of sonar equipment in the Atlantic network, it makes the Soviet ships in the North Sea and the Atlantic from the mainland, must go beyond military hydrophone, so in theory the Soviet ships every time from the north out of the Atlantic will be found and tracking. The other part extends from California to Hawaii, then north to Alaska and Japan, and finally to the coastal waters of Japan.

[Air Force] world Gatlin original "Su Texas" system project, is one of the most difficult, the workload of the largest project in the world. The typical "Su Texas" device is mounted with a sealed container 20 hydrophones, each other are connected by a wired network, the final access node, and shore based command Chinese similar, these nodes are usually arranged at the naval base. "The amazing ability to distinguish Su Texas, to identify which specific Soviet submarines are through.

The U.S. and Japan have been working together to create the southeast water monitoring network, nicknamed "hook". The name comes from the network extended from Japan to Taiwan, Philippines, Indonesia, to the northwest and extends to the overall layout of Singapore, Malaysia, Thailand, looks like a China surrounded by the South China Sea "hook" (below).

"The quiet sea" blog article concludes that initially built network monitoring China underwater, reflects the China investment on marine rights and determination, comprehensive improve China Navy combat capabilities in coastal waters. This network further development, will affect China naval forces in the Western Pacific continue to deepen, get more right to speak in the Pacific and global affairs.
