My own experimentation with air bubbles has proven otherwise.

I understand from another article that the Chinese think they may have overcome the inability to maneuver.

That all sounds great. Hypersonic submarine that has a degree of control.

Problem I see is the ocean is dark. The "eyes" of a sub are via sonar. But this sub travels faster than sound. Even with passive sonar, by the time you get a sonar signal back from the whale, other sub, uncharted undersea mountain, or other debris in front of you, you've already hit it. Active sonar would be even less useful.

I'm sure even a small debris can do a lot of damage when you hit it at those sorts of speeds, not to mention what it would do to your cavitation bubble.

Reality is just catching up.

I wonder how it would sound on SONAR?

Sorry I dont see the value of a super sonic attack sub.

More dangerous threats that China/Russia could put there $$$

Okay let say it is possible.

If it is running that fast how does it use it sonar to listen. Better yet find out what is in the water ahead of them.

ASM would have less time to hit target. Maybe just drop ordinace in its path and let it come to you. You ever hit a rabbit while speeding.

Where does it get enough air to create the bubbles for crossing the Pacific.

Might work for a missile, but the purpose of a submarine is stealth. EVEN IF you could supercavitate right on over to our coastline (and that’s a supercavitated IF), I doubt you could do so quietly. The second that sub made the jump back from hyperseaspace, it’d be a sitting duck.

There is no power source that could generate the amount of focused energy to bring this super cavitation about.

Until we/they have fusion reactors, they can fahgeddabudit.

You probably need a bigger bathtub.
