In general, the important nodes of the aircraft carrier construction include the start, water, dock mooring test, sea test and delivery of troops. Once entering the sea test, the workload is almost 80%. Li Jie, a China carrier expert, said that the sea trial cycle is usually 3 months to 1 years, and there is no fixed restriction. The main purpose is to achieve the design standard. The first sea trial is usually a few days. The main contents of the test are power system, navigation system and communication system. Popular speaking is to drive, see clearly, connect. Li Jie said, from the official public report, the construction of domestic aircraft carriers is relatively smooth. From the end of 2015, the Ministry of National Defense announced the development of second aircraft carriers for about 3 years, and the construction time period was much shorter than the 4 to 5 year period of the normal aircraft carrier. Secondly, from the progress of construction on the Internet, boiler ignition test and scaffolding removal are relatively smooth. Li Jie said that even if some of the problems were normal, the Chinese Homemade carrier had at least 700 million to 800 million parts, and all the components were together without a problem. The British aircraft carrier had not been abnormal in the early days, but a leak occurred two weeks later, while the French De Gaulle propeller blade had broken and had to return to the dock. Li Jie said that whether the aircraft carrier will return to the dock before the sea trial is one of the important indicators to observe whether the aircraft carrier is built smoothly. Vasily Cashin, a Russian military expert, said in an interview with the Russian satellite news agency that the Chinese new aircraft carrier is highly similar to the Liaoning ship structure. It will not meet too much technical difficulties and will complete the test in a relatively short time. Taiwan Wang Bao said that the domestic aircraft carriers external weapons, sensors, lifesaving facilities and equipment have almost been installed. The improved 4 area array active phased array radar antenna and new electronic support measure antenna have been installed on the island. The rear of the ship is loaded with an air to - air missile, a 12 - mounted anti submarine rocket gun, a 1130 - million - hair near - defense gun and a multi - tube multi - purpose rocket launcher with a 18 - mounted red flag -10 ship. On the other side of the ship, self defense weapons should also be installed. Compared with the Liaoning warship, it has changed a lot, and the combat capability must not be the same. This is the first truly Chinese aircraft carrier with full combat effectiveness. When talking about the impact, Russian Satellite News quoted Kashen as saying that Chinas aircraft carrier group will greatly change the balance of power in the Pacific region. Of course, Chinas aircraft carriers are not used for expedition and interference in foreign countries, while carriers in western countries are often used for these purposes. Chinas aircraft carrier is used to defend its surrounding waters. First of all, it is used to protect the area where nuclear submarines are on duty. Some American scholars and media seem reluctant to look at it. Chinas nuclear powered aircraft carrier: is the worst nightmare of the US Navy to be a reality? On the 5 day, the national interests of the United States said that in the past 10 years, China has taken great strides to obtain and improve an old Soviet aircraft carrier and build a new aircraft carrier with the same money. According to some reports, China will use nuclear power on fourth aircraft carriers. It is estimated that the 003 type of displacement will be 110 thousand tons. It will be the first aircraft carrier in the world since 50s of last century to be able to compete with the strongest supercarriers in the United States. Details are not known now, the carrier speed or 30 section, can carry 70 carrier aircraft - like the American Nimitz or Ford class carrier. Chinas accumulated experience will undoubtedly join the design and construction process to create more effective and powerful aircraft carriers. The United States Navy is often exhausted from the Baltic Sea, the Mediterranean Sea, the sea of Japan, the sea of Japan to the South China Sea, according to the 3 report of the American defense news. In order to alleviate the above situation, US Defense Secretary Matisse decided to change the deployment mode of the US aircraft carrier and make the trend of aircraft carrier even more difficult to predict. He believes that when a big power is in competition, the Navy should be in an unpredictable place, which can make potential rivals feel stressed.
