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

A Wide Range of UUVs</div>
</div>
</div>
One area where unmanned underwater vehicles (UUV) and 
unmanned surface vehicles (USV) would make a splash is in Chinese 
anti-submarine warfare (ASW) efforts.<br />
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.<br />

System of Systems</div>
<div class="field-body">
Future Chinese anti-submarine warfare systems will rely on a wide
 arsenal of autonomous and surface unmanned vehicles, in addition to 
acoustic (and other types of) sensors installed on the ocean floor.</div>
</div>
</div>
In addition to active and passive sensors located up to 
3,000 meters underwater, the Underwater Great Wall will be supported by a
 wide range of USVs. Chinese researchers intend that these autonomous 
USVs will be able to work in conjunction with the seabed sensor picket 
line, and autonomously locate and track enemy submarines.<br />

To fully unlock the potential of UUVs, Chinese scientists
 will have to master autonomous intelligence for these underwater 
robots, not just individually but also to teach them to 'swarm', in 
working together with one another with little or no human oversight, as 
well as with other naval platforms.  Other technologies would include 
new forms of underwater communication and datalink<br />
 technologies, as well
 as precise navigation systems and multiple sensor payloads.<br />

    The Type 094 SSBN can carry up to 12 intercontinental ranged

In April 2015, the Office of Naval Intelligence (ONI), the U.S. Navy's 
intelligence arm, released its latest report on the PLAN, titled "The 
PLA Navy New Capabilities and Missions for the 21st Century".  In it, 
ONI identified several key PLAN trends of concern to the US military, 
including the development of new anti-access/area denial (A2/AD) systems
 with additional power projection capabilities, and increases in PLAN 
training and global deployment. </div>

    The first 052D destroyer, the 7,500 ton Kunming, was launched in 
late 2013 and commissioned in March 2014 (its hull number, 172, was not

In the six years since the last 2009 ONI report, the PLAN is stated to 
have made substantive improvements in technical capability and 
operational experience. One of the most notable is the Type 052D 
destroyer and HHQ-9B and YJ-18 missile combination.  First commissioned 
in 2014, the Type 052D Luyang III guided missile destroyers (DDG) is 
China's most capable air defense and multirole destroyer, equaling the 
AEGIS combat system in some regards.  One such Luyang III DDG is seen 
here at dockside, loading an HHQ-9B canister into one of its forward 
vertical launch system (VLS) cells.  The PLA Navy is looking to build up
 to 12 Luyang IIIs before transitioning on to the bigger Type 055 
cruiser.</div>

the older 90km ranged HHQ-9 to make it China's longest ranged naval SAM.
  The Luyang III DDGs, in addition to its 64 versatile VLS that carry a

    The 7 radars include a X/UHF AMTI Active Electronically Scanned 
Array (AESA) radar on the front, two X/UHF AMTI/SAR/GMTI AESA radars on 
the twin booms, two X/UHF AMTI AESA radars on either side of the engine 
nozzles, and two more radars on the end of the booms. AMTI and GMTI 
radars are used for tracking air and surface targets, respectively, 
while SAR is used to provide detailed imagines of ground targets like 
bases and infrastructure.<br />

    The Haiyan UUV is an underwater glider, which can dive under 
1,500m below the ocean surface, for up to 30 days.  These 70kg drones 
(or future militarized versions) could be deployed enmass by Y-8Qs to 
provide a quick but long-term sensor solution, in areas like the Taiwan 
Straits, against enemy submarines during war time.<br />

In six years' time, the 2021 ONI report on the PLAN could 
feature the continuation of current trends, such as the launch of 
another Chinese aircraft carrier, more quite submarines and larger 
warships.  Additionally, the PLAN of the early 2020s is likely to be 
testing stealthy drones, underwater robotic swarms, lasers and rail 
guns. </div>
