Chinese submarines thread

Re: Chinese sub thread

that goes for most sub-launched missiles. They are sub-launched by first being launched in a tube, then flow to the top by gas(CO2?) and then released into the air where it is fired. Even SLBMs.

But I doubt a Sunburn will fit. Maybe a Krypton, but Sunburn? No way......
(Does the design of the two missiles have any relations? They both have the 4(ramjet+ fin) configuration.)

Re: Chinese sub thread

poeye, a popular method for launching anti ship cruise missles for china is to seal the missle in a tube. the tube is fired out of the submarine, and rises to the surface. it breals open and the missle flys out. this has already been done on for the yk-82, and may work for a moskit.

The US and Russians pioneered this technology(in different ways). That's exactly the same way a Harpoon is sub launched.

@FreeAsia2000 - I know of that exercise that you quote. What that article doesn't tell you is how many times the LA's targeted and destroyed the Collins SSK's. This went on for a number of days, and Collins proved to be very silent sub designs. Surprised USN analysts. Diesel subs are extemely quiet, including Songs and Kilos. This event clearly identified a shortcoming in USN naval force protection.

Because my good old USN that I love so much can't find a desiel boat. Nobody else can either....

When I was in, I knew guys from sonar that were in the process of localizing diesel sub tracks in real-time. I was there and saw it. It's just harder with diesel subs and the USN is out of practice. But what do I know, I was not a sonar man myself. The USN can find diesel subs, it's just alot harder because of their quietness in using only their batteries. It goes without saying that if the submarine is not operating correctly (ie not exploiting the ocean environment to their advantage)(poorly trained)(poorly maintained) it stands a good chance of being detected.

As far as I know, the AS-17 Krypton is an airlaunched antiradar missile, so I doubt a submarine would care to bring them along, even if they could be fired from the tube. I think the warhead is too small to do any significent damage to a ship.

And the standard SS-N-22 Sunburn has a diameter of 740mm. The Kilos only have 533mm tubes, and I'm sure thats what most of the PLAN sub is using.
This means that if they were going to fire the Sunburn out from their types, massive modification would have to be done...

Humm..My son says they can't..You say they can. Something is amiss. I don't doubt you or my son. The present day methods of tracking subs is classified as are all other methods....Well that's why the USn uses other nations subs for training.....

not kilo, but 93 or 94 perhaps? it would be especially interesting if the jl-2 launch tubes on board the 94 were capable of firing anti ship crusie missles as well.

no one said it had too be moskit, as the club-s with improved range is a perfectly fine alternative.

Re: Chinese sub thread

the largest torpedoe tubes ive ever heard of on a a submarine was 650mm so a sunburn thats 740mm wouldnt work plus the tube that takes the missile to the surface

Re: Chinese sub thread

but we dont know the size of the 93s torpedo tubes yet, nor do we know the size of the 94s jl-2 tubes(although that definitly is big enough to fit a moskit).

 

[sango]

Re: Chinese sub thread

i doubt either the type 94 or the type 93 will have torpedoe tubes larger than 650mm this would require the development of a new torpedoe that would be large and probably expensive

Re: Chinese sub thread

This is a "wait and see" item for me. AFAIK China doesn't have any 650 mm torpedoes. Only the 53 cm varieties.

Re: Chinese sub thread

Iran has 3 Kilo class subs. Currently they are being retrofitted by the Russians to launched the Club-S missiles. They are a direct threat to U.S. aircraft carriers stationed in the Persian Gulf and Arabian Sea.

In the past, the U.S. govt warned Russia not to sell any more Kilo subs to Iran. But apparently that does not stop them from retrofitting them with Club S missiles.
