China Sets up Underwater Network for Sub Communication, DetectionPosted: January 4, 2017
SCMP says in its report “Does China’s deep-sea tech upgrade point to submarine signals network under Pacific?” today that China is updating its 400- to 500-meter deep buoy network in the Pacific.
China says the network is used for civilian purpose, but according to experts, the data of water speed, temperature and salinity collected by the deep-sea sensors of the buoys would help Chinese submarines avoid harmful turbulence.
Even though the sensors can also monitor the submarines of other countries, as the readings are collected once a year, the military application of the buoy network is limited though SCMP begins its report by saying, “Technology used for undersea research has clear military applications, including improving communications with submarines, say experts”.
Now the upgraded buoy network enables “the buoys to send data directly back to bases in China via satellite technology, Xinhua reported on Sunday”.
That enables Chinese submarines to communicate with home bases immediately and China to detect and track submarines of other countries.
SCMP says, “Lockheed Martin said six years ago it was developing similar technology for US submarines.” We do not know whether it has successfully developed the technology and whether the US has used the technology to set up a network of buoys similar to China’s. However, we are sure that China has successfully developed such technology and is setting up a network for its application.
