The "air bubble" theory that would allow a submarine to move through the ocean at supersonic speed could be closer to reality through the work of Chinese scientists.
Called "supercavitating," the theory is being developed into new technology by scientists at the Harbin Institute of Technology's Complex Flow and Heat Transfer Lab, according to the South China Morning Post, and it could allow a submarine to reach supersonic speed underwater.
The "air bubble" technology would allow a submarine to travel from Shanghai to San Francisco in less than two hours, if the technology can actually be pulled off, according to the newspaper.

Likely not at all. It didn't need to. The entire point was to deliver a nuclear weapon just beyond the lethal radius of the SSBN that fired it, straight down the path of the incoming torpedo that they just detected.
Good in theory but. No matter what you do to reduce friction you still have to push a lot of water out of the way. To move the boat forward one boat length, that is the equivalent to the displacement. That takes energy to move xxx tons of water. Now figure how many boat lengths it has to move per second at supersonic speeds. ... You get close to an energy rate (power) figure. As Scotty says ya canna violate the laws of physics captain.
Yes. Inertia has an influence.
Energy is required to “push” water molecules out of the path of the “super-sonic” submarine.
IIRC, resistance increases at the “square” of the speed...
> There is also the issue of transitioning from 1200 fps to regular speed.
The speed of sound in water is not 1200 fps; it’s closer to 4879 fps.
Geesh, I’m smarter than I thought. :) Thanks for recognizing that.
Supersonic speed = 768+ mph. Yea, in a boat. Crewed by Chinese.
What could go wrong? :-o

Add a few other crew mates such as
Wai So Dim
Yu Stin Ki Pu
Chin Tu Fat
Hu Yu Hai Ding
Yung Thin Ho
and Phuc Dat (this is a real name)
and you have a winning team!
This would be impossible, impractical, and expensive for subs. For a new class of intermediate range nuclear devices... maybe not so much.
3000+ MPH submarine, huh? Impressive.

I swear, the so-called civilizations of the world are constantly working to devise new ways to run, control or destroy the world. I say anyone who actively WANTS control is exactly the type of person who should be kept as far away from the levers of control as possible. Too much enthusiasm is not a good thing in some matters. Politicians and rabid cop wannabees are two examples come to mind first.
Supersonic fragmentation?
And the herniated torpedo lifter. Wun Hung Lo.
I read this in a book or saw it in a movie a long time ago but don’t remember the exact source. Sounds like science fiction to me.
The Russian supercavitating torpedoes are powered by liquid-fueled rocket motors. It’d be interesting to see how that mode of propulsion could be scaled-up to work in a manned submarine, considering the amount of fuel it would have to carry.
There was a name in the credits of a show I used to watch — many Seinfeld — that made me laugh every time I saw it. Forget the first name, something like:
Suzi Fukuto.
LOL!
They drown?
funny comments ping
also I thought I saw article on this subject couple years ago, went looking and found the following
