The great underwater wall of robots: Chinese exhibit shows off sea drones

Chinese robot subs will blanket ocean floor soon

The Chinese Navy, the PLAN, appears to be following in the footsteps of its sister service, the People’s Liberation Army Air Force, in making growing investments in unmanned surface and underwater systems, aka “drones.” A new Chinese exhibit shows the scale of the potential future.

One area where unmanned underwater vehicles (UUV) and unmanned surface vehicles (USV) would make a splash is in Chinese anti-submarine warfare (ASW) efforts. ASW capabilities have been a longstanding weak spot for the PLAN, leaving it at a disadvantage to American and Japanese attack submarines. As a response, the China State Shipbuilding Corporation (CSSC), which builds virtually all PLAN warships, has proposed an “Underwater Great Wall” of sensors, positioned on the seabed floor, to listen for enemy submarines. (The US had a similar system on the Atlantic Ocean floor to listen for Soviet submarines.) Such underwater listening posts may already have been installed near the giant PLAN base at Sanya, Hainan Island in the South China Sea. On a more optimistic note, CSSC suggested that an Underwater Great Wall would be useful for warning against natural disasters like tsunami, and could be used to collect research data on marine life and geology.

Underwater Great Wall of China The Underwater Great Wall may be centered around stationary sensors on the ocean bed, but autonomous unmanned underwater vehicles will be a critical enabler in not just tracking enemy submarines, but finding them. Also note the large AUV's reflection on the display glass.
