U.S. media said the Chinese submarine cruises have become increasingly frequent, but noisy and easy to detect
data for China Navy’s submarine fleet
According to the U.S. “Connection” magazine website “DangerRoom” column published December 27, David – Akers (DavidAxe) of the article said, the U.S. Navy submarines to China recently conducted a confidential assessment ; for the U.S. Navy, the assessment results were mixed. On the one hand, the Chinese Navy submarines (about 60) increasing the number of combat patrol, which means that China is enhancing the ability of the Navy, but also more emphasis on the impact of the Western Pacific.
the other hand, a large number of underwater activities to the U.S. more trailing and tracking Chinese submarines opportunities. U.S. strategic analysts in the clouds a ray of light found in clouds, they learned that the Chinese submarine noise than anyone expected to be large; This means that the balance of power in the Pacific in favor of Washington’s direction.
By 2007, China’s conventional submarines and a few nuclear-powered submarines each carried only a few patrols. In 2005, China basically does not make any submarine patrols. Over the years, due to lack of skilled operators and submarine submarine of its own mechanical problems, the Chinese navy submarine has been parked most of all naval base in China.
article said, not as long as the Chinese Navy’s submarine activities, the U.S. Navy reconnaissance aircraft, submarine detection and tracking of ships there is no chance to get information on China’s submarine force. The most important thing is not informed that the Chinese submarine in dive activities will produce much noise. According to U.S. Navy submarines use passive sonar to track the sound of them: the greater the noise the submarine, the more easy to detect; so, the greater the likelihood of being destroyed.
no definite information in the case, U.S. intelligence officials can only guess to determine. A famous U.S. Navy analyst said that in such circumstances, people tend to be more conservative guess. Conservative estimate is that China’s submarine technology behind the decade than in Russia, more than two decades behind the United States.
But now, the Chinese submarine patrols are more frequent. The expert disclosure, “a recent two years, China’s conventional submarine in the Philippine Sea and other regional events were frequent, which makes the U.S. military get more accurate data; Based on these data, the U.S. Navy submarines to China for a new evaluation . “The unnamed experts based on the assessment made a brief introduction.
the report’s most surprising is the information: In addition to submarines purchased from Russia, China’s new submarine to the “first convergence zone” to be detected. “The first convergence zone” refers to the underwater submarine about 25 miles away from the ring, is the point spread of the sound waves bounce outside the convergence region to come together.
the Cold War, the U.S. Navy ships, submarines, arranged 25 miles apart, form a network to track submarines underwater Soviet submarine. Russia in the 1990s with the introduction of the first generation of quiet, conventional submarines, the United States that the convergence may be difficult to achieve a detection zone. However, the U.S. Navy found that Chinese-made submarines, Russian submarines than twenty years ago, the noise is also large. The expert said, “Obviously, the United States conducted the first convergence zone submarine detection and tracking to a Chinese submarine.”
assume China’s current submarine design change, the U.S. submarine is fully capable of any in the future quickly defeated China’s submarine warfare; This would think that the U.S. aircraft carrier attack land targets China to pave the way. Coupled with the speed of China’s submarine construction slowing, and the U.S. submarine construction rate doubled; Chinese submarine noise may cause people to make the balance of power in the Pacific a thorough re-evaluation.
