I know this is on Yahoo News but is this some kinda April fool? Submarine at the speed of sound (about 1 mile per second in seawater depending on depth)....I'm not buying it.

imagine the sonic boom from that

True.........I think about 600 knots is more realistic:

Two issues.

If you make a navigation error at that speed, it's going to hurt when you hit something.

And submarines use sonar to detect objects. Remind me what the speed of sound through water is? And then tell me how you can use sonar to detect and avoid objects when you are travelling faster than the speed of sound.

All assuming it was physically possible in the first place.

Based on this principle which has been proved

The Russians stole the idea from Gerry Anderson I believe.............

Editorial artistic license aside this is actually an interesting subject. It appears the speed of sound statement in the article is a gross exaggeration but they are developing a supercavitating small submarine capable of 100 knots. A far cry from sonic speeds but pretty nippy by general standards still.

Dunno how; but I ended up, from there, watching Oregon Highways Dept. dealing with an 8 Ton whale carcase by dynamiting it..........back in 1970....apparently, it didn`t go to plan......................................
