I don't quite understand what you are saying here, but I will try to answer or ask
I have evoke only 3 submarines classes, nuclear are or before able to reach a max speed of 40 + kn on severals dozen, others in general 25/32 sometimes up to 35 the less fast is the 091 to 22 Kn.
Now If ou think all are able to move at ~ 40 kn please do.
I was answering your
only 3 submarines classes, they are all faster than 39+
as you said, do I get you right? If I was right understanding you, then my question still remains, why do you think 093 able to reach max speed at 39+ not serious? After all, it is not the speed they are going to be used in daily operations.
Now you bring in
others, but they are new arguments, without you naming their type, I can not comment.
Obviously yet with China impossible have and in more classified for all countries so you can't get exact datas as armor for a tank or a nuclear weapons but possible have datas enough precise close, very.
093 is clearly better as 091 the 1st but is very medium for her noise all reports confirm it.
And if only two 093 are build it's that they does not give satisfaction...
In general, we don't have good data about SSN or SSBNs. We may have good or even exact data on tanks, but nobody like us can have even good data on SSN and SSBNs, they are all classified. Even if US navy has a good idea about 093 (if they has get close and recorded the noise), they will not release it to public for various reasons. Non of the reports you mentioned actually claimed to be sourced from US navy department, did they? They only used the words "noisier", not numbers of dB.
To me, I don't buy the "all reports confirm it". These reports are just like the "floating diagrams" that I mentioned earlier. So I will not do any thinking based on them. Of course, it is your choice to believe them.
My basic point (therefor disagreement with you) is that those "reports" can be equally wrong as they are right, so unless you know something classified then bringing in them as a base of argument is meaningless. And of course, if you really know something classified, you will not argue with me because using these infors to argue with me will break law on your part. So let's just rest this.
Regarding "two 093 are built", that does NOT indicate "not give satisfaction" in my opinion.
Remember, China maintains a very small number of SSNs due to her strategic choice of being defensive unlike USN. China will not field any type in large numbers even she is satisfied of them. Type 093 was something developed decades ago, it is necessary to develop a follow on type after this time span to keep up to new technology development, that is why 095 is coming soon. Actually, this is how USN is doing, Los Angeles, Sea wolf and Virginia, how many years were they apart? So imagine, if China as you suggested should have built 10 type 093(number of satisfactory by your standard??), how many 095 should be built then? another 10? That is a whopping 20 SSNs. That is surely not necessary for PLAN today.
BTW, by "two 093" I assume you did not include the B and G variants. In total, how many 093x are there? Remember, you should not count them as different types, but variants or batches of the same type (same generation of tech, same basic design etc.) In that case, it is more than two, does that mean satisfactory?
Also, a very important reminder is that you should not compare PLAN to USN in terms of size, at least not now. You should compare PLAN to French or UK navy. PLAN has a mission profile more resembles UK and France. France has 6 SSNs active, PLAN (according to wiki, please correct if it is wrong) has 5 type 093 built, one is being built, early 091 was decommissioned, that gives 6 SSNs active (I am not counting 095 from rumors), good number, right?
only 3 submarines classes are able to these speeds, Seawolf 40 in trials have reach 44, Alfa 41 in practice 39 and Papa 44 trials but Soviet reactors less good, reliable in more.
