Chinese Unmanned Underwater Vehicles (UUV)

Underwater guerrilla warfare and ambush. UUVs are strategically deployed at certain shipping lanes and choke points, where they use acoustic decoys and other methods to lure enemy submarines into traps. Once enemy submarines get within range, UUVs launch torpedo attacks and then quickly withdraw and sail to the next area to set up traps all over again, a kind of underwater shoot-and-scoot tactic.

This would be very useful for China to secure and shut-off much of the underwater entrances along the First Island Chain from access by enemy submarines.

Besides, these UUVs can also be stationed around entrances of enemy submarine bases, and have them sitting on the seabed while waiting for enemy submarines that are leaving the base or returning to the base before launching ambush attacks.

However, for enemy submarine bases located very far away from Chinese shores (such as Guam, Sydney, Varsha, Pearl and Kitsap), using conventional propulsion wouldn't be sufficient. That means mini nuclear reactors (such as designed to propel ULR torpedoes) would be required for UUVs tasked with faraway missions.

Furthermore, these UUVs must be able to operate and conduct missions autonomously for long durations of time too.

^^^ If they are small enough they might be able to be piggy-backed on nuclear submarines and released closer to site.

Good. In fact, China should keep doing this, but expand them as far as the Arabian Sea and the US West Coast.

Of course, when they are pointing fingers at China doing this and that, they would never dare to report on how Chinese fishermen have been collecting those UUVs dropped by them in the South China Sea and East China Sea for the exact same purposes.

Typical 贼喊捉贼 act here.

Another bionic manta ray underwater drone. This one is jointly developed by Northwestern Polytechnical and Ningbo Research Institute. The image only shows a scaled display model. The real UUV is substantially larger, with a wingspan of 4.2m and weighs 700kg. Maximum operating depth is 1000 meters. It can carry various payloads such as cameras, sonars, and other sensors.

Seems like this hasn't been made public until quite recently?

Making your nuclear submarine way easier to detect with UUV attached to them is maybe counterproductive. Could piggy back on cargo or fishing ships at this rate and drop multiple without notices at the shortest distances of bases from cargo shipping routes.

The problem with making ambushes is energy use while waiting. They need to be dropped at the good time before a conflict would be critical.

I guess they could be useful being released from places like the many South China Sea islands that China control/built.
