Squall torpedo

You MAY be correct about the old torpedo. There was a British TV
programme that pointed with good evidence to this fact.

However - I think a point is being missed here ?

Super-Cavitation Technology ?

What can be applied to a torpedo can equally applied to a submarine.

The Russians have retired their 'Golden Bullet' 45 knot Alpha Class Submarines.

A 'Super-Cavitating' submarine that uses this ability as a 'sprint' ?

Interesting no ?

Both you and the website author are being goofy.

The site clearly states that this is an _anti-submarine_ torpedo.

In addition, the website is wrong about this being the cause for the sinking
of the Kursk. The Russians have concluded that it was actually an older,
conventional torpedo that probably caused the loss.

Which would completely defeat the any modern submarine's greatest advantage
- stealth. You might as well paint a huge, luminescent, noisy bulls' eye
on it.

Not easily, rocket propelled submarines would seem
a non trivial development.

The Russians have retired their 'Golden Bullet' 45 knot Alpha Class
Submarines.


Given their design , liquid metal cooled rectors etc that
was very wide of them

And makes so much noise that every SOSUS station on the
planet hears them

Interesting no ?

Is submarine's stealth cruising the only situation the submarine can be
caught in? Let's say it's already located and has a torpedo coming at it. Or
some situation develops where it has to travel very fast to some place, e.g.
some rescue operation or something, it doesn't really matter. In those
situations I wouldn't give a **** about some SOSUS tracking my ass but would
be very thankful to the engineers that provided me with this neat feature.

The question is how much are you prepared to give up
to get it ?

Supercavitation requires a large gas generating capacity
and humongous amount of thrust. To achieve this the
Shkval has a honking great solid fuel rocket that takes
up most of its interior space and has a range of less than
6 miles.

Push your submarine 5 miles downrange this way and you'll
delay the helicopter by perhaps 3 minutes while providing him
with a confirmation of your presence and a precise location

Personally I'd prefer a decent decoy.

Yes, I see your point. You're absolutely right. It is quite impractical (or,
better, impossible) with today's technology, but it might prove to be an
interesting concept in future.

I dunno. ASW is a cat and mouse game. If the mouse wears a bell it
makes the cat's job easier. This has been true since the beginning
and I doubt it will ever change.

Another thing to consider is that which can be done on a small scale
(a torpedo weighing a ton) may not be possible on a large scale (a
submarine weighing thousands of tons). I suspect the ride through
this "bubble" is probably not very smooth and that will cause it's own
set of problems with submarine systems.

And if the amount of propellant to do this for a torpedo poses safety
risks for the sub, consider the tankage that would be required to
carry sufficient propellant for the whole sub. If solid propellant
were used it would be a "one time use" system, and that means you are
sacrificing other things (money, space, sensor capacity, etc.) to get
away once. With these other systems you might evade detection all
together or escape many times.

At the end of the day the weapon will probably give U.S. forces some
pause, but whether or not is it practical remains to be seen.

Q: How does a solid rocket fuel compare to liquid fuel as far as
specific thrust versus density of loading?
I can see why the two exotic torp oxidizers/monopropellants I am
familiar with, propylene glycol dinitrate and hi-test hydrogen
peroxide, are not 'sub-friendly' but I don't know how either would
compare to say ammonium perchlorate/aluminum/hydrocarbon solid fuel.
Looks like powered duration on Skval is about 90 seconds max.
Launching it will surely give a very noisy sound signature and a fix
if there's more than one searcher close by - on its origin.
If it is used against a formation it looks like there would be a trade
- one sub for one target.
