China’s new Jin-class ballistic missile submarine is noisier than the Russian Delta III-class submarines built more than 30 years ago, according to a report produced by the U.S. Navy’s Office of Naval Intelligence (ONI).

The report, which was first posted on the FAS Secrecy News Blog and has since been removed from the ONI web site, is to my knowledge the first official description made public of Chinese and Russian modern nuclear submarine noise levels.

Force Level

The report shows that China now has two Jin SSBNs, one of which is based at Hainan Island with the South Sea Fleet, along with two Type 093 Shang-class nuclear-powered attack submarines (SSN). The Jin was first described at Hainan in February 2008 and the two Shangs in September 2008. The second Jin SSBN is based at Jianggezhuang with the North Sea Fleet alongside the old Xia-class SSBN and four Han-class SSNs.

The report confirms the existence of the Type 095, a third-generation SSN intended to follow the Type 093 Shang-class. Five Type 095s are expected from around 2015. The Type-95 is estimated to be noisier than the Russian Akula I SSN built 20 years ago.

Missile Range

The ONI report states that the JL-2 sea-launched ballistic missile on the Jin SSBNs has a range of ~4,000 nautical miles (~7,400 km) “is capable of reaching the continental United States from Chinese littorals.” Not quite, unless Chinese littorals extend well into the Sea of Japan. Since the continental United States does not include Alaska and Hawaii, a warhead from a 7,400-km range JL-2 would fall into the sea about 800 km from Seattle. A JL-2 carrying penetration aids in addition to a warhead would presumably have a shorter range.

Julang-2 SLBM Range According to ONI
Although the ONI report states that the Julang-2 can target the Continental United States, the range estimate it provides is insufficient to reach the lower 48 states or Hawaii.

.
Alaska would be in range if the JL-2 is launched from the very northern parts of Chinese waters, but Hawaii is out of range unless the missile is launched from a position close to South Korea or Japan. The U.S. Defense Department’s 2009 report to Congress on the Military Power of the People’s Republic of China also shows the range of the JL-2 to be insufficient to target the Continental United States or Hawaii from Chinese waters. The JL-2 instead appears to be a regional weapon with potential mission against Russia and India and U.S. bases in Guam and Japan.

Patrol Levels

The report also states that Chinese submarine patrols have “more than tripled” over the past few years, when compared to the historical levels of the last two decades.

That sounds like a lot, but given that the entire Chinese submarine fleet in those two decades in average conducted fewer than three patrols per year combined, a trippling doesn’t amout to a whole lot for a submarine fleet of 63 submarines. According to data obtained from ONI under FOIA, the patrol number in 2008 was 12.

Since only the most capable of the Chinese attack submarines presumably conduct these patrols away from Chinese waters – and since China has yet to send one of its ballistic missile submarines on patrol – that could mean one or two patrols per year per submarine.

Implications

The ONI report concludes that the Jin SSBN with the JL-2 SLBM gives the PLA Navy its first credible second-strike nuclear capability. The authors must mean in principle, because in a war such noisy submarines would presumably be highly vulnerabe to U.S. or Japanese anti-submarine warfare forces. (The noise level of China’s most modern diesel-electric submarines is another matter; ONI says some are comparable to Russian diesel-electric submarines).

That does raise an interesting question about the Chinese SSBN program: if Chinese leaders are so concerned about the vulnerability of their nuclear deterrent, why base a significant portion of it on a few noisy platforms and send them out to sea where they can be sunk by U.S. attack submarines in a war? And if Chinese planners know that the sea-based deterrent is much more vulnerable than its land-based deterrent, why do they waste money on the SSBN program?

The answer is probably a combination of national prestige and scenarios involving India or Russia that have less capable anti-submarine forces.

China’s Navy Makes “Impressive” Strides, Says ONI
November 20th, 2009 by Steven Aftergood
An ongoing modernization effort has provided China with an increasingly sophisticated and proficient naval force, the U.S. Office of Naval Intelligence (ONI) said in a new assessment (large pdf).

Notably, China has “developed the world’s only anti-ship ballistic missile,” which ONI said was “specifically designed to defeat U.S. carrier strike groups” in the event of military conflict over Taiwan.

“China’s modernization efforts have principally focused on preparing for a Taiwan conflict, with a large portion directed at developing capabilities to deter, delay, and if necessary degrade potential U.S. military intervention,” the ONI report said.

Although China has recently deployed naval vessels far from its shores to protect Chinese shipping from piracy, “it is important to note that none of these operations indicate a desire on the part of the PRC to develop a constant global presence,” ONI said. “Beijing’s ambition appears to remain focused on the East Asian region, with an ability to protect the PRC’s maritime interests in distant seas when required.”

Let's see, US Naval intelligence screwed up its report on the J-XX, now it wants to screw up Chinese sub records too? Lol...For the record, the Type 096 is undergoing construction right now if that makes you feel any better. Lastly, don't quote other nation's tech when you're worse off yourself, since Russia has had the most sub incidents and accidents across the world.

lockh33d brother, never challenge some secret source, from the

article A.V. post;

Now, you know whats secrecy ?:china::cheers::china:

it seems AV's unpopular post dose hurt. but his post remind me 2 things:
1) isn't that exactly the way how some chinese members mock at indian weapons. so, maybe, there will be less sarcasm in the future if they took this lesson.

2)although PLA has made some marvelous breakthrough, it is still 20-30 years behind the lead. weapons on par with j10,052B,99A,WZ-10 was made by US in 1980s.

however, it is also unwise to compare a 093 with a 30-year-old Victor, coz 093 is to Victor as j10 is to F16a/b.

But then again, we lack a Cold War tension period, where we can boost our military spending. And of course, one would be stupid to think China is nearly on par with the US, for we've got a lot to catch up on, USA ftw. As for the Russians, though they're still a tad ahead of us in military tech, numbers for sure, what we lack behind in military terms we make up with in terms of infrastructure and economy. :tup::tup::tup:

meh believe what you will, personally a blog telling me something like this is to be ignored but we all know though there is progress, Chinese sub are behind technologically to that of the Russians and US
