PLAN test and experimental vessels

Northwestern Polytechnical University's biomimetic manta ray-inspired unmanned underwater vehicle, "Soaring 5," can scan underwater topography using sonar and collect temperature, salinity, and depth data.

It can withstand 200 atmospheres of water pressure, has a range of hundreds of kilometers at full speed, and can glide for one thousand kilometers using a variable buoyancy system (similar to the principle of hypersonic flight).

It can navigate autonomously using an inertial navigation system along a planned route, and can also transmit satellite data from a surface-based vehicle to the underwater vehicle via a self-organizing network.

For reference, that would be about 200 meters of depth in sea water.

The 100-meter flatdeck test platform has been spotted (again) recently, this time at Huludao. Posted by @AllSourceA on Twitter.

Either this is the same ship that has sailed all the way from midstream Yangtze to Huludao, or that this is the second unit of the same class.

I think its fair to say its the unit we previously saw at Jiangsu Dayang. Similarly to the target platforms shown in the picture which appear to also have been manufacturered there. The vessel may not have sailed there under its own power.

Has it ever surfaced at defense shows previously?

As a naval-based platform, no.

Oh my goodness. See watermark




Also I'm gonna read into this vaguepost a bit, from Hole Hole Gay Guy Hainan Chengdu: "It really is a huge lump. Even on a Type 055, it would still look very large. I wonder whether there will be an even bigger new ship to use it, huh."

If the rumours about a new batch of 055s are correct, since this gun is currently undergoing testing, it would make more sense for the next generation large DDGs to be equipped with it (rather than the 055)
