This years celebration of the Chinese navy is of special significance, a good opportunity to display the weaponry of a world power. Chinas first conventional power domestic carrier is preparing for the sea trial, Newsweek said. China has two very important strategic concerns in East Asia: the Taiwan independence issue and the South China Sea dispute. US media said China is seeking to dominate the region and therefore needs an army that can compete with American hegemony. In recent weeks, China has conducted large-scale military exercises, demonstrating the determination to safeguard the interests of the country. China learned from historical experience that great powers need a strong navy, and they are moving forward in this direction, said Terence Edward McNight, a U. S. retired naval major general. Reported that the Chinese navy is now one of the largest and most advanced navy in the world. The Liaoning ship was the first aircraft carrier purchased from Ukraine. The construction of domestic aircraft marks Chinas ambition for the future. For China to build a domestic carrier, Matthew Finnell of the CSIS, a Washington think tank, said it was an important step in the right direction. Its one thing to redress the old Soviet carrier like a Liaoning ship, but its another thing to rebuild a new one, even in the reverse engineering, Matthew Finnell said. He believes that, although not necessarily top, China is likely to need 6 to 10 aircraft carriers, which will allow China to have the worlds second largest naval force ahead of the rest of the world. The article also makes a data comparison between Chinese and American navies. The US Navy has about 32.5 000 service personnel and 282 deployable warships, including 11 nuclear powered aircraft carriers. The US Navy also owns 3700 aircraft, the second-largest aeronautical fleet in the world (the first is the US Air Force). This does not include about 200 auxiliary vessels and reserve ships. Compared with this, the Chinese navy has 23.5 10000 service personnel and 700 aircraft. Although there are more than 700 ships, most of them are patrol boats, support vessels and old vessels. Only about 220 are combat ships. According to the article, China hopes that by the year 2020, the combat ships will be able to reach 351 and eliminate old warships. McNight said that although the United States has the most powerful navy in the world, the gap between China and the US Navy has been narrowing day by day. The US Navy officers clearly realized this and set up the target of 355 warships before 2050. But the United States alone has not been able to catch up with China in its construction speed.
