Western analysis of China’s upgraded version of the Yuan-class submarines a substantial increase in acoustic performance
Data Figure: China’s latest network spread a” Yuan “class submarines in the U.S. newspaper photos

“China’s most advanced conventional submarines in the Yangtze River into the water!” few in China submarine pictures circulating on the Internet, has recently attracted sustained media attention to the Western military. Never seen such a Chinese submarine, the Western media finds it for the latest Chinese “Yuan” class submarines, and submarines from the shape to determine the level of quiet and a substantial increase in performance of underwater navigation, deep water is more suited to the task.
“China Lada” noise plummeted
submarine began in early September photos spread out on the Internet, at first just to see Western experts Chinese Internet users to make mischief, but with more clear photos of the release, they are convinced that this is a new “meta” class submarines. United States, “Global Strategic Network” 23 given a free hand to name it “041C”, meaning the construction of China’s previous two 041A-and 041B-type “element” class submarine upgrades.
Western habit to refer to Chinese dynastic name of the submarine at all levels. “Yuan” class submarines active in China’s most advanced conventional submarines. “Global Strategic Network” reported that the previous two “meta” class submarines and the Russian “Kilo” class submarine is similar, but the appearance point of view, the new “meta” class submarine is more like a Russian “Lada” class submarines. “Lada” class is Russia’s most advanced fast-attack submarine, commissioned just last year.
“Global Strategic Network” also reported that, “Lada” class submarine hull design silencer watts, but also a more quiet propulsion propeller. “Kilo” class submarines because they have excellent acoustic performance and is called “ocean black hole”, but “Lada” class submarine noise than the “Kilo” eight times lower. If China’s new submarine using the “Lada” quiet technology, will no doubt greatly enhance the ability of water to survive.
“Jane’s Defense Weekly,” 22 according to photos, the same that the submarine is similar to Russian “Lada” class. Reported that the submarine has a thick solid shell and shorter tail, reducing drag underwater. Submarine tower shell around the more rounded lines, height than the previous “meta” level low, especially around the shell and the convergence occurring at the arc-shaped hull fairing, more in line with fluid.
“Jane’s Defense Weekly,” said the submarine is currently unable to confirm the specific size, displacement, but you can see its head and had the “Yuan” class submarines similar to the earlier “Yuan” class submarines displacement of about 3000-4000 tons.
For design purposes, “Jane’s Defense Weekly” analysis, the new bridge part of the disclosure of the submarine boat has been extended, possibly to set up submarine-launched anti-ship cruise missiles, air defense missile system or a new rescue capsule. China Aerospace Science and Industry Corporation in 2008, the Zhuhai Air Show held live a diminished version of the C-705 anti-ship missile, the missile is entirely possible to be installed in the new submarine boat near the bridge.
“Jane’s Defense Weekly,” that the submarine may be advanced submarines, like the West did not install air-independent propulsion (AIP), the system allows the submarine continued to sail in about two weeks underwater without floating power generation, thereby enhancing the operational covert.
foreign media to find the “Russian blood”
launched in China in recent years for a new submarine, the Western media as a Russian-made submarines used to evaluate the performance of reference things, on the grounds that: “China is a Russian submarine industry to help build, and China’s dependence on Russian submarine technology no weakening.”
“Global Strategic Network,” the article said, with new disclosure This one, Wuchang Shipyard has built three “meta” class submarines, the first one 041A seems to be Russian “Kilo” 877EKM type of piracy, while the second vessel 041B is considered “Kilo” of 636 “Chinese brothers”, the third new ship into the water as in the previous display “China Lada” in the title. But China’s increasingly high level of imitation, showing the Chinese submarine engineers have a more creative.
“Jane’s Defense Weekly,” the same very curious on this issue, saying that from 1994 to 2006, China imported 12 from Russia, “Kilo” class submarine, then China is it possible on this basis with Russia, “Ruby” submarine design bureau jointly designed it? “Jane’s Defense Weekly” interview with “Ruby” Design Bureau. The representative said that Russia is willing to sell submarines to China, but declined to answer questions about Sino-Russian joint design of the submarine issue.
rapid growth of China’s submarine force
“Jane’s Defense Weekly,” that the submarine since 1994, China introduced a third new conventional submarines, neighboring countries could deepen concerns, prompting many Asian countries to increase or create a submarine fleet.
Russian media for the rapid growth of China’s submarine force for the statistics. Russian ‘arms trade center world, “23 reported in 1994 to 2006, China bought from Russia a total of 12 submarines, also between 1994 and 2004, equipped with 13 039 made” Song “class submarines. As the most advanced “Yuan” class submarines, the report said citing data from the U.S. Pentagon, the Chinese navy will be building 15, which opened in mid-2010 the construction of five vessels.
