Plan Type 093/094 Nuclear Submarine Thread

Another reason for building the 094s, despite the dated technology, is that the PLAN needs to train a core cadre of boomer operators for the 096s.

Re: PLAN submarines Thread II

I would like to point out there is no direct evidence that the Chinese really ever intended to serial build any boomer design in the sense "serial" is normally understood where a sizeable number of nearly identical boats is built in a short span of time. They may have always intended to create a fleet of several small classes of just around 2 boats each, separated by 7-10 years, evertually reaching a steady state of around 7-8 operational boats in 4-5 classes. (assuming operational life for each class of 30 years) This is not most cost efficient, but it does avoid block absolescence. Once the steady state is reached, in 20 years and at least 2 more new classes of SSBNs or so from now, they would be in a state where they will usually have a few boats bordering on obsolescence by international standards. But most of the time, on average, they would also have a few boats that's newer, and presumably more advanced, than boats in other navies that relies on serial building a single class of SSBN, like all the western navies now.
Having 8 boats of 4 classes is very inefficient in terms of cost, development and ongoing maintenance.

For the Type-94 SSBN, I think the intention was to provide a minimum deterrent with a single SSBN on constant patrol, which requires about 4 submarines.

So I think we will probably see another 4 Type-96 SSBNs, as they recognise Chinese submarine technology is still needs to improve with the following class.

Personally, I see China settling at 12 boats in steady state.

No. Don't know where you get the idea of having 8 boats in 4 different classes translate to very efficient in term of cost, development and ongoing maintenance. Unless these boats and each class shared huge number of similar components and modules and they could interchange these components among the 4 classes easily, it will be a logistic nightmare. And it is definitely not cost efficient and development will be long and expensive because you are going to divide your limited number of manpower, talents (engineers, scientists, etc) to develop four different classes of submarines, rather than gathering all your brain and industrial power to develop only one single class of submarine... then move on to develop the next and the next.

As to ongoing maintenance... anyone with engineering background would tell you that to maintain one single system is always easier as compare to having large number of different systems... and unless of the above points discussed.

The reasons for so many different type of submarines (or seemingly so many different type of submarines) are of the following,

1) different mission suites
2) Most submarines are actually incremental improvement over previous class and they actually shared components that can be inter-use
3) China is still moving around, searching and improving their submarines system until they pinpoint one that they are really satisfy then they will start to mass produce that one type. and at this stage, we are seeing quite a number of types of submarines because the Chinese had not settle on THE ONE.

Re: PLAN submarines Thread II

IMHO, you are trying to have it both ways, Schumacher. Here's why.

The Type 094 design is actually not "very new." Do you remember when the Type 094s were built?

The first one was seen at dock side (meaning it had been launched) in what, 2006? The second in 2007. They probably were each under construction for at least two years before being seen, if not more. This means the Type 094 design was finalized at least ten years ago. It is not only not "very new," it is not "new," at all. The money they have put into the Type 094 is indeed "sunk" money.
....................
Same thing, they make it operational now. The design may not be all new but they must have put new stuffs, invested in new skills, crew to make it work otherwise why did they not deploy it then but now.
Making & keeping something like SSBNs operational are huge costs in itself, if they're not effective deterrent, the right thing to do would have been not to operate them at all, despite the sunk costs.

Yes it is expensive. But the Type 094 is a better deterrent than the single Type 092...and they are training crew in operations.

In this way, if they get what they are hoping for in the Type 096, they will have increased deterrence out of the Type 094 that they can keep for some years to come, trained crews in operating them, and then be ready to go with the better deterrence and operations in the Type 096...and learned a lot of very valuable lessons along the way that will ensure that the Type 096 is indeed a lot better than the Type 094.

We will see how well they do with the Type 096. We will be able to tell by how many they build and how quickly they are able to make them operational.

So you are admitting that you made a mistake in your previous assessment in saying that it is very efficient in terms of cost, maintenance and development?

Re: PLAN submarines Thread II

High noise level information of 092 and 094 SSBNs are from US intelligence community, what creditable data do you have to suggest they're wrong?
Normally, intelligence services would not release noise levels of enemy subs, even if they are high. This would tell the enemy to make improvements on their subs. It was a U.S. spy, John A. Walker, who gave info to the Russians that their subs were emitting too much noise due to propeller cavitation. After the Russians redesign their propellers to reduce cavitation, the noise level of their subs have decreased significantly.
