Chinese USV Development Thread

[by78]

A model of a small USV for disaster relief operations. It carries instruments to measure water flow rate and depth during floods.

– Dimensions (L x W x H): 2.05m x 0.85m x 0.45m
– Weight: 35kg
– Payloads: depth sounder, acoustic doppler current profiler, etc.

A similar hydrological survey USV from a competitor, also used to measure water flow rate of rivers and flood areas:
– Length: 1m
– Weight: 5kg
– Capable of autonomous navigation and dynamic positioning (i.e. remaining stationary at a fixed position using thrusters).

Both the JARI-A USV and the 100-ton smaller trimaran test platfrom USV are seen moored at Lianyungang Port. Google Earth imagery dated 3 November 2025. Posted by @type36512 on Twitter.

Data offloading perhaps?

During the launch of 076, not sure if anyone here noticed something in the background.

It's nothing, it's the original sailless submarine from 2019

Yup that's it, I'm just amazed of how big it is, since this original photo doesn't do it justice.

An academic paper excerpt depicting a trimaran ship hull model with two pumpjets. The model looks rather similar to the trimaran USV at Guangzhou that Sutton has written about in Naval News in late-October. Posted by SOYO on Weibo.

Which academic paper was that?

Now that we have clear picture of the Guizhou trimaran submarine, this is pretty clearly not it.

Zhejiang has developed China's first 100t class USV at JiaXing shipyard. It is 31.6m long, 5.5mx15x deck area,
a 15-ton payload capacity, and ample power supply.

it can be used for underwater search, EW, island transportation and various dual use scenarios. Seems quite modular and flexible. Can be used as drone swarm and carry payload.
