#2According to the article this uses plasma explosions and a working medium of metal particles.
Wouldn’t both lead to easier traceability (sound, metal)?

#4This seemed like science fiction to me, but aparently it is real, the technology was introduced in a 2009 paper cited 20 times https://www.worldscientific.com/doi/abs/10.1142/S02179849100...

In comparison to conventional nuclear sub this method would be much quieter. But also much faster over long distances. You have two issues with subs, stealth and positioning. If you know, or have high confidence, that a combatant sub force is in X pos, and have Intel on its AVG speed then you can plan accordingly. Tech like that described above means a sub force can be more quickly repositioned, or deployed. You have Intel that X vessel was docked two days ago? Well it could be in the south pacific today.
One thing to keep in mind, there is a reason this is published publically. PLA want this out there for a reason, either to sow worry and concern or to mislead.

#8Wow that is super awesome and could be used for underwater weapons as well.
In combination with propellers for quick acceleration it should work too.

Source? Cavitation on propellers is a major source of uncloaking. This sub sounds fast but traceable—perhaps more ideal for a weapon than a vehicle.

The method described in the present article doesn't rely on rotating propellers that produce vibrations, thereby reducing one of the major sources of noise.
