As a point of reference, although the actual speed is likely much greater than 100 knots (the Navy offers only lowballed figures to the public) even if we take that as gospel, provided fuel depots along the way a supercav sub could cross the entire Atlantic in 18 hours not counting the time needed to refuel. With that taken into consideration a 24 hour transit is realistic, compared to 1 week or more for a nuclear sub (also taking the 20 knot 'official' speed as truth).

You really seem to have waltzed in out of nowhere and started lecturing people who have put a lot more time into studying the matter than you have in how to accomplish these things while at the same time viciously insulting them and their dreams. Please imagine how you look to someone who is on the receiving end of your arrogance and abuse. There is much you don't know on the topic, be willing to admit that, willing to read about it and concede that perhaps you aren't an authority on the matter and it's not your place to go around shouting people down and presuming to tell them how to do these things or when/how they can/should be done. In some cases you're stating things already obvious and included in the plans and in other cases you're presenting things as damning facts which in fact are common misconceptions. Just cool it, stop acting like a bigshot, and be willing to learn from other people instead of presuming to force your own opinions on them when in many cases those opinions are based on incomplete knowledge.

Oh I know, it's faster than a speedboat and supposedly they have some method of redirecting the noise to make it stealthy.

What I'm getting at is that what Darpa says it will be used for is not always what it's actually intended to be used for.

>Though stealthy might be a problem with the noisy supercavitation system.

From your link:

"A supercavitating vessel could make a lot of noise. Applying stealth would be to reduce the sound and to direct the detectable sound away from sensors in a predictable way. Being able to alter the detectable signature or create or have unmannded decoys could be useful. Also, by travelling at high speed and possibly having the sound that is given off being not that much faster, the supercavitating vessel could use a detectable burst of speed and then go into silent and stealth mode. It would be known that the supercavitating vessel "
