Chinese Unmanned Underwater Vehicles (UUV)

Answer revealed! According to the official description, AJX002 is a new unmanned mine-laying system.
According to the official voice-over:
“自主巡弋,出击深蓝!海上无人作战方队开过来了。受阅的新型无人潜航器、无人艇、无人布雷系统,具备隐蔽布放封锁、自主探测识别、集群组网攻击等作战能力,是海上作战的奇兵利器。”
“Autonomous patrols, striking into the deep blue! The unmanned maritime combat formation is approaching. On parade are new unmanned underwater vehicles (UUVs), unmanned surface vessels (USVs), and unmanned mine-laying systems, which feature covert emplacement for blockade, autonomous detection and identification, and swarm-networked attacks—a surprise force and potent asset in maritime operations.”
Not really, it clearly fits under the unmanned underwater vehicles category. Maybe it also fits under the unmanned mine-laying systems category, but we don't know that.

I'm pretty sure the narration refers to equipments sequentially, so AJX002 is a mine layer.

Yes, that was my thought from the start, when that narrated part happened.

The mines they also showed btw could be its payload.

Has there been discussion or indications of using UUVs as mobile pop-up radars? Such systems could pop their heads over the surface anywhere, scan the sky for aircraft, potentially cueing VLRAAMs to target, and go back underwater before being destroyed. They would complicate enemy aircraft deployment patterns due to having no way of predicting when their formations (especially tankers/AWACS) will come under detection range.

Many issues with such a system.

Firstly would be power. Radars, especially long range ones, require huge amounts of power. Unless you want to add mini nuclear reactors to these, the availability of onboard power will be a major limiting factor.

Secondly would be survivability. These things are slow and rely on stealth as their primary defensive measure. Surfacing and popping off radar will immediately give away their location. Even assuming opfor don’t immediately engage it with an ARM, which they can easy carry as standard after the first time you pull this trick, once the location is know, opfor will have a much easier time hunting these down with ASW assets once they know where to focus their efforts. Basically these will become disposable radars that you use once and expect it to be destroyed soon after. Making it massively uneconomic.

Lastly is just the need. Why go to such lengths to get a surface radar deep into the ocean when you can just use AWACS, UAVs, satellite and many other available existing assets to get the same or similar enough radar picture without the costs and risks involved in using an unmanned sub.

Using the UUV like this is like suggesting you load army tanks and artillery onto cargo ships to provide fire support. Sure you can do it, but why would you bother when you have far better and more suitable assets to do the same job better already?

The only scenario where I can potentially see putting radar on a UUV as somewhat worthwhile is if you also add in VLS launched SAMs as well, and have these operate as hidden anti MPA bastions for your manned subs (since they will almost certainly lack the speed and endurance to keep up with manned nuclear subs).

So, if one of your manned subs gets detected and is being actively hunted down by enemy MPAs and ASW aircraft far from friendly land based air or naval support, it would be worthwhile to surface one of these to spam SAMs at the airborne hunters to save your manned submarine, even at the cost of the UUV. But that will require a much bigger UUV unless you make SAMs that can be launched via torpedo tubes or some sort of erection launch system.

I'll concede the points about survivability and to a lesser extent power limitations, but I will say that the case for the need is pretty clear: to allow you to get coverage in areas where other platforms cannot operate at sufficient resolution. Radar UAV may not necessarily be able to penetrate deep enough into hostile airspace to send back an appreciable amount of information, whereas a radar UUV would essentially trade one set of threats for another, making it potentially useful in situations where other platforms are not. Satellite ISR is as far as I know not at a stage where it could fulfill the same role. A radar UUV would have greater penetration capabilities and could thus serve functions otherwise difficult to pursue, e.g. pre-positioning one in the path where you would expect your own bomber fleet to be intercepted, or if you have a sufficient number spread out, you could activate one in short order close to where you suspect enemy formations are massing, which you may not be confident in being able to do with UAVs.
