China ramps up submarine activity

Strategy Page reports on increased activity around China’s maritime periphery:

Recently, the Taiwanese Navy detected an unidentified submarine outside one of its major naval bases. Ships and helicopters pursued the contact, but the suspected submarine left the area. A Chinese boat was suspected, mainly because for the last decade, Chinese subs have increasingly been showing up close to Japan and South Korea as well.

Chinese Song class diesel electric and Han class nuclear powered boats have been detected and tracked with increasing frequency over the last few years. In that time, one of each of these was spotted stalking the American carrier USS George Washington, as it headed to South Korea for a visit.

China is rapidly acquiring advanced submarine building capabilities, and providing money (for fuel and spare parts) to send its subs to sea more often. Moreover, new classes of boats are constantly appearing. The new Type 39A, or Yuan class, looks just like the Russian Kilo class. In the late 1990s, the Chinese began ordering Russian Kilo class subs, then one of the latest diesel-electric design available. Russia was selling new Kilos for about $200 million each, which is about half the price other Western nations sell similar boats for. The Kilos weigh 2,300 tons (surface displacement), have six torpedo tubes and a crew of 57. They are quiet, and can travel about 700 kilometers under water at a quiet speed of about five kilometers an hour. Kilos carry 18 torpedoes or SS-N-27 anti-ship missiles (with a range of 300 kilometers and launched underwater from the torpedo tubes.) The combination of quietness and cruise missiles makes Kilo very dangerous to American carriers. North Korea and Iran have also bought Kilos.
