China’s Telephone, Hanging Array for 6000m Deep Sea CommunicationPosted: May 29, 2017
In its report on what China’s Jiaolong deep sea submersible has achieved in its submerge operations at world deepest Mariana Trench in northern Pacific, huanqiu.com gives no photos of the submersible. As shown on top, four of the six photos posted by the website are water telephone-6971 and acoustic hanging array used for communication between the submersible and the mother ship more than 6,000 meters deep in the trench.
As there are no wire links between the telephone or array and the submersible or between them and the mother ship, there is speculation that the photos show China’s advanced deep sea communication equipment, which certainly can be used for military purposes.
