Would be so interesting to know informations about range and loitering time. A bit perplexed about the need stay close to surface to rely informations and the latency of informations to launch torpedos from a distant operator for these kind of systems. These kind of systems will require some good AI to be swift to react.
Chinese Unmanned Underwater Vehicles (UUV)

Very useful for defending of larger, manned allied submarines against enemy ASW efforts.Using UUVs to ambush enemy anti-submarine patrol.
However, the problem stems from how to make these types of UUVs travel together with those manned submarines as "underwater wingman drones", since they have neither sufficient speed to catch up nor sufficient endurance to follow them.
Either the manned submarines have to piggy-back carry them along with their deterrence/war patrol, and only release them once in designated patrol zones or when enemy encounter is unavoidable - Or that these UUVs would have to be nuclear-powered as well.

My guess is they don't. These UUVs would be deployed independently from manned submarines. They would be used to weaken enemy ASW presence in mission areas manned submarine would operate in instead of forming a formation with them which would completely defeat the purpose and only draw enemy ASW assets to the location of submarines it was supposed to protect.

A confirmation that China is currently developing X-tail rudders for submarines. Images below show a procurement document from the China Ship Design & Research Center (a.k.a. 701 Institute). The document asks manufacturers to submit bids for a set of 55kN-m electro-hydraulic steering gear (withPlease, Log in or), to be used to actuate X-shaped stern rudders. The steering gear must be able to deflect all four rubbers at the same time up to 35 degrees to either side (i.e. 70 degrees total). The steering gear must weigh ≤1350kg.
This might be related. A scale unmanned submarine with X-tail is currently undergoing validation/verification tests in a lake somewhere in southern China.
