Yuan-class submarine force the U.S. to update all the ships anti-submarine system

 Chinese submarines and other countries, like in accordance with the progression in the development of the submarine, can be divided into two basic forms: nuclear and non-nuclear power. Both nuclear submarines with conventional submarines. The former is the Navy began construction in 2001 to a new 093/094 nuclear power submarines. As old nuclear-powered submarines 091/92 alternative. in accordance with the Chinese nuclear submarine construction and control system technology, 093/094 and can not be advanced level. but the 093/094 design have a certain deterrent capability is.

in conventional submarines submarines, China has in the past relied mainly on the former Soviet Union up to 84 of the R, W-class submarines. These submarines are manufactured in the former Soviet Union 40-50 last century's. application of technology has a very aging submarine . the face of the current . It is the second generation of conventional submarines. exterior design by the French, battery components and other advanced equipment. In 1997, two different versions of the boats were captured. The former is designed appearance. while the latter is a reference to France, the latter.
Information Center under the U.S. Navy data show that since 1997, China has an annual construction rate of 3-4 vessels equipped navy. By 2007, the Chinese navy is equipped with a total of about 30-40 ships ; Song-class some called their third-generation submarines.
weeks) underwater. Its appearance means that China's conventional submarines can stay underwater the first time, middle-depth waters of more than 1 week.
093
nuclear submarine built since 2003 have been recorded since at least three Experimental Yuan-class submarines in service. According to the information provided by the Department of Naval Intelligence that China may want to create the number of additional ships at least 5-8. to make up for ability characteristics of the defects. while it's taken similar to the Russian conventional submarine technology, the sound of water features has been significantly increased. construction. This is consistent with the Chinese navy to seek water level displacement is much larger than the This will force U.S. aircraft carrier in advance to start the update, including all surface ships, including anti-submarine capability. The cost of large projects have been approved in the Congress under President Bush and implemented.
