Comments on: Super Cavitation and the Truth

Take a close look at the bow of the Russian submarine Sarov. It has a supercavitating bubble dome and two intakes running the long axis of the sub just forward of the con. A caterpillar is used to produce sea water cavitation bubble injection behind the dome.
The AIP is in fact a super compact steam generator (Fusion Cavitation) in tandem with a Kaluga KTP 7i condensing steam turbine. Suddenly a little diesel sub becomes the test bed for the new features of the Lada class boats. Other builders of subs doing similar research.…..gotta think outside the box and know what to look for.

To the poster “DualityOfMan” :

You wrote: “Do you realize that cold war warships were equipped with anti-submarine missiles which dropped nuclear-tipped torpedoes?”

If the idea is only to sink enemy ships, then there are notoriously cheaper nuclear options to accomplish that than building submarines, yeah.

I wonder if the Russians and Chinese are splitting rent on a lakefront house over on the shores of Lake Pend Oreille..

chrisram is right. Especially about the “fire” part. :)

Sigh.

Yes, the Alfas were very, very fast. They were also loud, tiny, (1/2 the displacement of a Los Angeles class) and expensive.

Do you realize that cold war warships were equipped with anti-submarine missiles which dropped nuclear-tipped torpedoes? I imagine that one of those would do pretty well against an Alfa.

Now not even I will open that new link.

I did NOT reduce my original link to a “bit-ly” ! That was “Defense Tech” who did that! My original link led to Wikipedia’s list of navies.

Part II : Of course: Russian ammunition is too dumb to turn even a little bit. That's why it relies exclusively on nuclear warheads to hit any target. "Guidance was nonexistent in initial designs, as the missile was intended for nuclear warhead delivery. Later designs reportedly include terminal guidance and conventional warheads of 210 kg (460 lb). The missile controls its direction using four fins that skim the inner surface of the supercavitation envelope. To change direction, the fin or fins on the inside of the desired turn are extended, and the opposing fins are retracted." http://en.wikipedia.org/wiki/VA-111_Shkval#Design...

and

to the poster “joebuff”, who wrote:
”…The Soviet supercavitating torpedoes were intended to have nuclear warheads, thus avoiding the need for much or any of an accurate firing solution. The Naval Underwater Weapons Center has reportedly developed a supercavitating torpedo that is able to use good target-homing technologies…”
