China’s Submarine Fleet, Evolution & news

Guys ... I really don't get it :hitwall::crazy::hitwall::crazy:

Is it so much difficult to take a look in advance before You start a new thread in a topic that clearly already exists and even more for a report that was already more than twice posted during the last few day !!!!???
:mad:

The 430,000-square-foot plant will guard subs from prying eyes.

China is building a factory so big that when it's done, it will be able to accommodate the construction of four submarines at once—out of sight from military enthusiasts and spy satellites alike.

According to Popular Science, Bohai Shipbuilding Heavy Industrial Corporation is building the plant in Huludao, Liaoning Province. The place will have two parallel assembly lines. The gigantic hall reportedly is where China will begin construction on is latest attack submarine, the Type 095.

Despite having control over its Internet and press, the Chinese government has had enduring problems with military enthusiasts sneaking pictures of new ships and aircraft under development or construction. While some of this is useful to telegraph China's broader intentions and give a hint of its capabilities, the rest of it is considered a nuisance. Building an indoor submarine factory keeps sensitive subjects such as the hull shape of a submarine or even the propeller design a secret.

This does not necessarily mean China now has a submarine-building edge over the U.S. The U.S. Navy commissions about two submarines a year, each of which takes about three years to build. That puts U.S. submarine construction at about six at a time, ahead of this factory's four. Of course, China builds submarines at other locations too, and may even build them a little faster.

U.S. submarines are also built indoors. Here's a Virginia-class submarine with its pumpjet propulsion system under wraps.

Speed isn't everything. Even if China ends up capable of building more submarines per year than the United States can, there's the question of quality. The Type 095 is expected to be quieter that the second tranche of Los Angeles-class attack submarines that were built in the late 1980s, and Russian Victor III or Akula-class submarines built in the early 1980s.

In other words, China is approximately 30 years behind the United States in submarine quieting technology. Chinese submarines in the 1980s were about as quiet as American submarines from the 1950s, while modern American submarines such as the Seawolf or Virginia-class boats are so quiet they're described as "quieter at 25 knots than the Los Angeles class at pierside." This is not a field where China has been able to close the gap.

A nice self-tranquilizing exposition. Good to know that China is just trailing approximately 30 years behind the United States in submarine quieting technology.... not over 50 years or even a century away :laugh: Have no worry D.C., China is just making up its quantity deficiency... nothing come close to your mighty fighting muscles :usflag: USA! USA! USA! 3X

When this enclosed submarine factory begins operation later this year, the Bohai Shipbuilding Heavy Industry Co. (BSHIC) will be able to quickly build nuclear submarines. Assembling SSNs in a building also provides the advantage of sheltering against the weather, not to mention nosy spy satellites.

Now the prying eyes of sky are blinded, they will have to resort back to the old, traditional methods of intelligence gathering... human spying! Scouring over all the blogs with military interests for any leakage will be part of the attempts in addition to all kinds of tapping by those alphabet agencies :D:P

093A is roughly equivalent to improved Los Angeles (more advanced sensors, roughly same acoustic level but inferior speed), so I don't see why 095 can't be in Seawolf's ballpark.

The Type 093/094 already got the reactor with the capability of the natural circulation, which means it can sail silently at 20 knots.

Many tightly-held beliefs are just the groundless bigotry, often sound more like a dogma, or a fairytale...

Here's a well-known piece of story from nearly a decade ago, merely as an illustration as well as a reminder.

The uninvited guest: Chinese sub pops up in middle of U.S. Navy exercise, leaving military chiefs red-faced

By Matthew Hickley - Daily Mail Online - Last updated at 00:13 10 November 2007

When the U.S. Navy deploys a battle fleet on exercises, it takes the security of its aircraft carriers very seriously indeed.

At least a dozen warships provide a physical guard while the technical wizardry of the world's only military superpower offers an invisible shield to detect and deter any intruders.

That is the theory. Or, rather, was the theory.

American military chiefs have been left dumbstruck by an undetected Chinese submarine popping up at the heart of a recent Pacific exercise and close to the vast U.S.S. Kitty Hawk - a 1,000ft supercarrier with 4,500 personnel on board.

By the time it surfaced the 160ft Song Class diesel-electric attack submarine is understood to have sailed within viable range for launching torpedoes or missiles at the carrier.

According to senior Nato officials the incident caused consternation in the U.S. Navy.

The Americans had no idea China's fast-growing submarine fleet had reached such a level of sophistication, or that it posed such a threat.

One Nato figure said the effect was "as big a shock as the Russians launching Sputnik" - a reference to the Soviet Union's first orbiting satellite in 1957 which marked the start of the space age.

The incident, which took place in the ocean between southern Japan and Taiwan, is a major embarrassment for the Pentagon.

The lone Chinese vessel slipped past at least a dozen other American warships which were supposed to protect the carrier from hostile aircraft or submarines.

And the rest of the costly defensive screen, which usually includes at least two U.S. submarines, was also apparently unable to detect it.

According to the Nato source, the encounter has forced a serious re-think of American and Nato naval strategy as commanders reconsider the level of threat from potentially hostile Chinese submarines.

It also led to tense diplomatic exchanges, with shaken American diplomats demanding to know why the submarine was "shadowing" the U.S. fleet while Beijing pleaded ignorance and dismissed the affair as coincidence.

Analysts believe Beijing was sending a message to America and the West demonstrating its rapidly-growing military capability to threaten foreign powers which try to interfere in its "backyard".

The People's Liberation Army Navy's submarine fleet includes at least two nuclear-missile launching vessels.

Its 13 Song Class submarines are extremely quiet and difficult to detect when running on electric motors.

Commodore Stephen Saunders, editor of Jane's Fighting Ships, and a former Royal Navy anti-submarine specialist, said the U.S. had paid relatively little attention to this form of warfare since the end of the Cold War.

He said: "It was certainly a wake-up call for the Americans.

"It would tie in with what we see the Chinese trying to do, which appears to be to deter the Americans from interfering or operating in their backyard, particularly in relation to Taiwan."

In January China carried a successful missile test, shooting down a satellite in orbit for the first time.

-------------------

And more recent stories of a Chinese sub stalked USS Reagan (2015), can be read here at PDF... at the end what truly matters is to learn from the many conflicting views (mind you, they came from the "established sources" only) that eventually it's just a matter of FAITH on what to believe or not to believe... all the involved hands have some selective things to show while at the same time also have some selective thing to hide in this very highly secretive affair by nature!

While the sensors and electronics are more advanced than those of the 688i.
Speed is the greatest weapon for SSN. If you can hit 35 knots, you're essentially immune to torpedoes. That's why even the oldest SSN will likely dance circles around the latest SSK.

China's SSN was always known having great speed.

Even the Type 091 once managed to sail above 40 knots, just having greater noise. The second generation can silently sail at 20 knots, which is a good thing. They finally managed to reduce the noise at the cruising speed.

If you are talking about WW II era, maybe. And even some of them can exceed 40 kn. The American Mk48 estimated speed is 55 kn, but we can be assured that it is higher.

For any submarine, its greatest strength is stealth, depth is secondary.
