No. Im suggesting that chinese nuclear sub tech still cant produce a SSN comparable to the yasen/seawolf/virginia classes. Unless we get a big surprise from type 095.


Do you have any ideia of what the noise level of type 095 will be? perhabs you are right, but what makes you say that?
Just pointing out your logical fault by highlighting your post. Your second sentence can be perfectly used to answer your first sentence. ;)

Something new has appeared outside the submarine halls at Huludao:

In the last picture there is something ~70m long just above the East end of the South hall, almost but not quite in line with the painting hall. Or are my eyes deceiving me?

I may not have an ideia of what the noise level will be, but i think that it will be hard for china to get a competitive type 095. IMO, type 095 is more important for china than type 096.

Active sonars are really powerful. For example, Turkey currently has the specs of a fairly modern active sonar element public.

The transmitting voltage response of the element is 151.5 dB microPascal/V at 1 m at 7.5 kHz. The driving voltage is 600 V. This means the sound intensity level (SIL) of the element at 1 m and 7.5 kHz will be 179.3 dB. Its receiving sensitivity is 10.5 dB higher. This element was used in a Turkish hull-mounted sonar for corvettes. That sonar looks like this:

View attachment 77546
Each vertical column has 8 elements, which means each vertical column will generate 188.3 dB (SIL). The increased gain (by 9dB) would make this equal to 197.3 dB. With a single column and a fairly noisy warship (let's say 140 dB), we can already detect submarines from around 600 meters away. With other columns, it is very possible that this sonar has a SIL close to 200 dB and an array gain of 30 dB. This would mean a 100 km detection range against submarines for our noisy corvette if ignore losses. If we account for losses this would decrease to 15-20 km.
I doubt it's 200db

200db is 100MW.
