China’s Noisy Subs Get Busier — And Easier to Track

[graphican]

Pakistan has just placed an order of 6 subs which wouldn't have been possible if Chinese Subs were not up to the mark. Not to forget India is getting P-8i in good numbers and if subs were that easily detectable, what's the point in going for them the first place? Also when China is making 5th Gen fighters and narrowing gap in other technology, what makes Wired think they are 20 years behind and still investing mindlessly in producing more subs? that doesn't make even half sense.

Where are the facts you talking about in the article?

The credibility of this article already got debunked.

its part of the racism. the white Americans truly think we are mindless and stupid.

'white' is the fantasy term they like to call themselves as there is no such thing as 'white' race. these are european americans, so we should classify them as such.

The noisiness of the sub depends on the quality of the manufacturing standard, since China can make the much more complicated turbofan engine, the sub silencer is a much easier technology to be mastered.

I see that US is again chestthumping to make sure their little friends in Asia won't jump off their boat.

never trust what they say its all propaganda.

They want to destroy our national pride.

Of course it is the propaganda.

You get your defence analysis from Wired??

So how did a Chinese sub surface in torpedo range of a US Navy CBG in 2007??

For passive sonar, you just generate noise in peace time so you don't give your acoustic signature away. Duh.

After reading this, I find it very difficult to believe that you actually worked on sonar.

What makes you think type 095 is comparable with Virginia class subs?

According to Chinese military sources, Type 095's quieting is at 105 decibel, Virginia and Seawolf is 90 to 100 decibel while later 688 Los Angeles is at 105 to 110 decibel. So Type 095 is between Virginia / Seawolf and later Los Angeles. Part of Type 095's quieting comes from the pumpjet propulsion.

Type 095 also carries "a small number" of cruise missiles in canted launchers (4?). The first Type 095 was launched in late 2010 and will enter service in 2012.

So, you wait for war to come and turn off the noise? Really??? That does not make sense to me at all.

Obviously you have no clue to use of deception in masking sound signature in navy ships. Gathering individual ship's sound signature is a modern day version of those old days photo-recon of enemy ship silhouette. With a data bank of ships sound signatures, a sonar operator can recognise an individual ship and whether it is freind or enemy.

To counter such intelligence gathering in peace time, it is normal to mask actual sound of a ship by generating fake sounds, and noise maker is one such device. In war time, turning off the noise maker, or altering the previous sound render enemy's sound signature data useless and make sonar operator's work harder.

There was a rumor that the Type 094 has pump jet and that Type 096 might have magnetohydrodynamic drive. Do you have any further info?

 

[ChineseTiger1986]

that Type 096 might have magnetohydrodynamic drive. Do you have any further info?

Both Type 095 and Type 096 have it, just check my EMALS topic.

Prefessor Ma has already made this a reality for PLAN.

Thanks for the info. But tell me this, if you have a noisier sub, you are letting it be tracked giving the first striker knowledge of where they are and a chance of taking them out. If you are operating with a different noise signature not a noisier signature I can take that argument.
It seems strange to my non military brain.
