China build only their own since enough few times, 20 years in first Song, medium SSK for quality despite this much better as 035 but others more old are only variants of Soviet Romeo etc..
Too new for do the best quality in more for this matter, special.
Western, Russians build since 100 + years

Despite what the attempted trolls may say, technological improvements in production can and do have major changes occur in a short time, the Germans and Soviets did so with their ships once a mature methodology of engineering is established, that is also why the PLAN could make major improvements with each succeeding sub class they produce.

We seen that in every sphere of technology in China Let see in fighter jet J7->J8->J10->J20
That is only 4 generation of fighter I bet US has much more generational changes than 4. It take me too log a time to research but I can dig it
But the main thing is that J 20 is at the cutting edge of technology.
"Much more" translates into one additional generation. China 'skipped' the very first generation of fighter jets because it bought 2nd generation jets directly from the Soviets and developed them from there. So it wasn't anything that China did at the time.

Now let see Navy destroyer development
Jianghu class(which is post WW2 type) then suddenly we have huge leap into type 52 then type 52C & type 52 D. If we follow Iron Man logic then Chinese destroyer should be at Fort Knox class now But that is not true
You need to read up on PLAN destroyer development a little more before you comment on it. First of all, Jianghu is a frigate not destroyer class. Anshan class was PLAN's first destroyer class. Luda (051) was the PLAN's 2nd. Luhu (052) was the 3rd . Luhai (051B) was the 4th. Luyang I/II/III (052B/C/D) was the 5th; you might even consider 052C/D as a separate class from the 052B. Each class is clearly an incremental improvement over the previous and reflects the PLAN slowly feeling its way towards modernity.

What we know as PLA wolf said is that in conventional submarine China is up there with the best. Recently China won contract in Thailand..Definitely the quieting technology ,sonar, battle management, weapon system should be similar or better in Nuclear Sub. The only difference is the power pack.But chinese nuclear technology experience transformational leap in the last 20 years. They are at the cutting edge of civilian nuclear technology working simultaneously at 4 third generation nuclear power tech from pebble technology to thorium cycle, breeder, and so on .
So it doesn't take leap of faith to assume that the similar technological leap occur in the realm of submarine nuclear tech.
And yet despite all your bloviation you have no real clue where Chinese sub tech is at, except that it must absolutely be super duper awesome.

Ok I forgot the luda and luhai.But they are dead end model there is no follow up program. Luyang II and III does not resemble it at all. But how many iteration that US navy gone thru their destroyer program
I don't have time to research but definitely more than 4 or 5 The main thing is your ARBITRARY multiplication number is arbitrary! and your assumption using model change as basis is just assumption with no scientific backing at all .Pull from the thin air.Using the same reasoning Chinese airforce should now be equipped with Phantom level fighter.LOL

My assumption is more logical because eventually any military progress reflect the country industrial base. Just because there is no information doesn't mean we cannot logical deduction by finding the analogue in civilian life

As I said we are at disadvantage because China doesn't release any information about their submarine program but Yes YUAN 039B&C at up there with the best because it won competition against German model

I don't exaggerate we do have some snippet about Chinese submarine program

At the recent 2013 Four Northeastern Provinces Cooperation Leaders' Conference held in Ordos, Inner Mongolia, Tan Zuojun, vice governor of Liaoning Province and former general manager of China State Shipbuilding Corporation, revealed that development of China's fourth-generation nuclear submarines and other high-tech weapons and items of equipment in the Northeastern Provinces of China had been completed. The news attracted considerable attention.

The fourth generation nuclear submarine features high performance and low noise

Military expert Du Wenlong pointed out that the main characteristic of the fourth generation nuclear submarine would be its high performance. Compared with earlier submarines, modern attack submarines differ significantly in offensive power, possessing both anti-submarine capabilities and also strong potential for anti-ship action and attacks on land-based targets. He pointed out that the fourth generation nuclear submarines of the United States and Russia already have these capabilities; China's fourth-generation nuclear submarines too will be equipped with the appropriate torpedoes, along with missiles suitable for use against other sea-going or land-based targets. In addition, the Chinese submarine will have low noise output, a key indicator for measuring a modern nuclear submarine's underwater survival capacity, as well as its ability to remain hidden during maneuvers, or undetected while launching an attack. He pointed out that the fourth-generation nuclear submarine will possess effective noise damping features, such as a quieter nuclear power plant with less vibration, and a more advanced hull muffler system, so that it will be difficult to detect even if within range of enemy sonar.

On the question when the fourth-generation nuclear submarine will enter service, Du Wenlong said that completion of development and completion of construction are two different phases - the cycle from completion of development to manufacturing, and then to fitting out and launch, can be very long, perhaps several years. Progress is determined by two factors: one is technical indicators, and the other is strategic need.

A significant enhancement of nuclear counterattack capability

Analysts believe that continual development of attack submarines and strategic nuclear submarines at times of peace, adding better performance and greater combat ability, can enhance strategic deterrence capability. China's strategic nuclear forces are weapons to deter third parties from becoming involved in local conflicts. China firmly adheres to the principle of non-first use of nuclear weapons, but the existence of strategic nuclear submarines will give China a stronger voice and more room for maneuver in the case of any crisis. In addition, Song Xiaojun points out that the United States, Russia, Britain and France all possess modern strategic nuclear submarines as a symbol of their status as 'Great Powers'; it is natural that China should be unwilling to lag behind

094 model at Harbin Institute of Technology (claimed by the poster).
One thing interests me is the description of the reactor section. It says that the reactor's first loop and main part of second loop are contained in the same radioactivity shielded section, this is different from 091 and 092.

I'm pretty sure I outlined a nonlinear technological progression to China's submarine capabilities directly reflecting the fact of China's rapidly advancing tech base in the last 10-15 years. The plain fact is we are all just plain speculating given the highly secretive nature of something like submarine acoustic levels, and saying one person is flat out wrong seems to me to be a laughable exercise of the blind accusing the blind that their blue is not blue enough.

I'm merely trying to ascertain as to how you arrived at the conclusion that a generational leap in the Chinese military sense is of the same technological magnitude as it is in the American one. It is a high-stakes assumption, even in the speculative realm, and one that frankly ignores the technological and industrial disparities between the two nations.

You seem to have forgotten quite a few things. You have also forgotten the Luzhou (051C) class, which is a descendant of the 051B, which is a descendant of the 051. The 052D is of course descended from the 052C, which is descended from the 052B, which is descended from the 052. Where did you get that Luda and Luhai are dead end models when there are direct descendants of both these classes? As for the USN, you actually should do the research, because I think if you did you wouldn't be so quickly dismissive. Its destroyers have gone through 6 generations post-WWII to get to the Arleigh Burke class:
1. Mitscher
2. Forrest Sherman
3. Coontz, Charles F. Adams
4. Spruance
5. Kidd
6. Arleigh Burke

And here's the PLAN again:
1. Anshan
2. Luda
3. Luhu
4. Luhai
5. Luyang I
6. Luyang II, Luyang III, Luzhou

Besides the Kidd being a descendant of the Spruance and the Charles F. Adams being a descendant of the Forrest Sherman, none of the rest of these destroyers have descendant/ancestor relationships. But of course this doesn't mean the USN didn't learn things from each design that they put into good use with the next design. The same thing goes for the PLAN. For example, the Luhu built upon the hull technology of the Luda and was made into a larger ship with a modicum of point air defense and a combat data system. The Luhai was scaled up even further and was the first attempt at stealth hull shaping, which was taken to a more pronounced degree with the 052B. The 052B itself was the proving grounds for the technology that led to the 052C and D designs.

The main thing is your ARBITRARY multiplication number is arbitrary! and your assumption using model change as basis is just assumption with no scientific backing at all .Pull from the thin air.Using the same reasoning Chinese airforce should now be equipped with Phantom level fighter.LOL
I'm assuming you understand the word "multiplication", so I am perplexed as to what exactly you mean here. I'm just going to assume that you are merely trying to communicate that you don't like my submarine tech progression timeline, in some weird roundabout way.

Actually, you really shouldn't be bringing up Chinese fighter technology, because it is a severe detriment to your argument of China being so advanced that it is skipping generations all over the place. Besides directly buying gen2 fighter tech from the Soviets, namely the Mig-21, China has in fact not skipped a single generation of fighter aircraft design.

Mig-21: gen2
J-7: gen2/gen3
J-8: gen3
J-10: gen4
J-20/J-31: gen5

In fact, it gets even worse for you. China did not even skip gen4.5 aircraft either, with its J-10B, J-11D, and J-16 fighter programs! You could even make the argument that late models of the J-8 and the JH-7 constitute a gen3.5 class of aircraft. All generations and half generations are fully accounted for. But yet according to your reasoning the PLAAF should have gone straight from J-7 to J-20! LOLOLOL

My assumption is more logical because eventually any military progress reflect the country industrial base. Just because there is no information doesn't mean we cannot logical deduction by finding the analogue in civilian life
Look, your entire argument this whole time has been "I don't like your submarine tech progression. It's faster than that because China is so much more awesome nowadays. How much more awesome? I am unable to prove anything to you, but it's definitely more awesome than you say". This is literally your entire "logical" argument.

There is literally nothing in this article that we don't already know. In fact if you want to talk about 4th generation subs, that's the Flight I/II LA class. Given the date of the article (2013), it is almost certainly referring to the improvements made with the 093B design. At most this article is saying that 093B is similar tech to early LA, and not necessarily a totally even peer competitor.

Not sure what you're talking about here. A one generation progression would not be considered a "leap". A 1.5 to 2 generation "leap" by the PLAN would be by definition NOT the same "technological magnitude" as the comparative tech generation of the USN. So if I say that the 093B has a made a 1.5 to 2 generation leap, by definition it means I'm saying that the PLAN skipped a half to a full generation of USN sub design progression to arrive at the tech level of the 093B.

The 052B itself was the proving grounds for the technology that led to the 052C and D designs.

It is very easy to poke a hole in your argument to begin with Anshan is ex Soviet Gnevny-class destroyers purchased in the 1950s and design & built in Soviet Union so it shouldn't be even counted. We are arguing here about the progression rate and why using class, model as basis is illogical

Now Luda is the first indigenous destroyer that is built in China I believe it is Dalian and Zhong hua shipyard 16 were built Yes you can count that as a class by itself.3700 ton

Now LUHU,LUHAI, are experimental ship Luhu is technological demonstrator for point defense and never entered into production It is power by GE LM2500 and equipped with French Radar and battle management and some other western sensor. But it is hard to fuse the various sensor from different source into effective combat system. So they built Luhai with more domestic sensor and after TAM 89 China cannot get the the GT Lm2500 so they have to use steam turbine. But PLAN is not happy with the result only 1 is built. IN other word those ships are EXPERIMENTAL and never entered into mass production. So it cannot be given a class designation

Luyang1 is again experimental ship to validate the hull an d machinery for Luyang 2 and Luyang 3
Yes you can call it a class by itself because it entered into mass production and there is increase in tonnage and better sensor and armament but you have to group it with Luyang2, luyang3

So the correct class designation for Chinese DDG should be

LUDA

Luyang1,Luyang2, Lyuyang 3,

So 2 class vs 6 for us So using your reasoning it should be 3 times as fast as US development rate


I'm assuming you understand the word "multiplication", so I am perplexed as to what exactly you mean here. I'm just going to assume that you are merely trying to communicate that you don't like my submarine tech progression timeline, in some weird roundabout way.

But yet according to your reasoning the PLAAF should have gone straight from J-7 to J-20! LOLOLOL

Now you are playing smart here you .MIg 21 is built and design in Soviet it shouldn't be even counted here
J7 and J 8 belong to the same class different function one is fighter the other one is interceptor , J10 is a class by itself, So do J20. So 4 class

NOW here you cleverly omitted the US air force class designation like F100,F105. You dare not to list all of them I don't have time to do the research But I bet It won't support your argument

Wrong he is talking about 4th generation submarine and 93B is consider 3th generation So he must talking about type 95,96

The Anshan class is indeed purchased ex-Soviet destroyer class, but if you are trying to say that the PLAN learned nothing about destroyer design from this class, then there is nothing more that you even need to say at all in this thread. Similarly for the Luda, Luhu, Luhai, and Luyang I classes. Please note that NOBODY except you thinks they do not belong in their own classes. Both the USN and the PLAN itself gives all of these ships their own class designator. And it is well known that the PLAN knew that it was starting from a low tech base and therefore did not want to waste money and build a bunch of ships in each class that were already obsolete when the keel was laid. But they needed experience building bigger and more complex ships. You can see this increasing size and complexity being played out very obviously and yet slowly and cautiously as we progress from Luda (3,700 tons), to Luhu (4,800 tons, point defense missiles, combat data system), to Luhai (6,100 tons, early stealth shaping design), to Luyang I (6,500 tons, more stealth shaping, better missiles, better sensors), to Luyang II/III (7,000 tons, even better missiles and sensors). Each subsequent iteration is bigger, more capable, and incorporates lessons learned from the previous iterations.

So you can keep dreaming about the PLAN only having gone through 2 classes of ships to arrive at 052C/D if you really want to, but you are utterly alone in this humorously whacky claim.

Now you are playing smart here you .MIg 21 is built and design in Soviet it shouldn't be even counted here
J7 and J 8 belong to the same class different function one is fighter the other one is interceptor , J10 is a class by itself, So do J20. So 4 class

NOW here you cleverly omitted the US air force class designation like F100,F105. You dare not to list all of them I don't have time to do the research But I bet It won't support your argument
Yes because I'm sure PLAAF learned absolutely NOTHING from the Mig-21 just like they learned nothing from the Anshan class. Are you even reading your own verbiage??? Early J-7 is clearly gen2 being not much more than copies of the Mig-21, while late models of it could possibly be considered gen3, which is why I wrote J-7 out as "gen2/gen3" in my earlier post. Early J-8 is clearly no more than gen3, and yet late models (for example, J-8H and later versions) could be considered gen3.5, as could the JH-7A.

And why should I even need to mention the F-100 and F-105? They fit into the gen2 and gen3 fighter categories. I also didn't mention the Corsair, the Crusader, the Phantom, the Falcon, the Eagle, the Warthog, the Hornet, and a whole host of other US fighters. So I guess according to you I'm trying to hide like 10 or 15 generations of US fighter aircraft from the discussion. But you do understand that when it comes to fighters, many of them fall into the same generation designation, do you not? There are in fact only 5 established generations of aircraft which pretty much everybody applies to the world of aircraft designation. The PLAAF had to slog through every last generation of fighter development except the first one, because as I said they bought directly into gen2 courtesy of the Soviets. No skipping generations. Too bad for you and your argument.

Wrong he is talking about 4th generation submarine and 93B is consider 3th generation So he must talking about type 95,96
If that article was referring to the 095 technology being already finished by 2013, then where is the 095? Meanwhile we have already heard that several 093B were in late stages of construction by 2014 and 2015. And this year we finally see photos of the 093B at pierside. That article fits in perfectly with the timeline of the 093B. On the other hand, no mythical 095 for you, sorry. Not a peep from any BBS, no leaked photos, no nothing. Feel free to hold your breath, though, because I guess according to you 095 is coming out any minute. Also, while the 093B is the third generation of PLAN subs, it is also roughly the equivalent of 4th generation of world SSN technology, which is what this article is describing.
