USA submarine tech back 20 yrs ago was using similar surface designs to make the flow turbulent to a point and increase speed and reduce noise. I know a guy that worked at Groton.
Possibly from same seed source, but not unreasonable to develop a variation for denser water independently. Noncompressible fluid theory combined with sub propulsion cavitation damping, and a late night Nat’l Geographic episode on shark propulsion might lead an observant engineer down the same path.
Kinda. Red Oct had a drive technology that was secret. This was a surface coating and material reducing laminar flow that tends to ‘suck’ and create drag. Perfectly smooth surfaces aren’t the fastest many times.

Just like in "The Hunt for Red October"?

Cool stuff. Science!!
Yes! Love cool tech!
