China launches two Type 055 guided-missile destroyers, widely considered Asia's biggest such combat vessels, at a shipyard in Dalian, Liaoning province, on Tuesday. [Photo/LIU DEBIN FOR CHINA DAILY] China launched on Tuesday two Type 055 guided-missile destroyers, widely considered Asia's biggest and mightiest such combat ship, according to witnesses outside a shipyard in Dalian, Liaoning province. Weapons enthusiasts published photos taken near Dalian Shipbuilding Industry, which has built two aircraft carriers, on internet military forums. They also described what they saw of the two giant ships' launches. When ships are moved into the water, their construction is basically finished. It is regarded as the most important step before sea trials. Water started to be pumped into dry docks where the vessels were built around 7 am, before the docks' gates were opened, witnesses said. Photos showed that there was a small launch ceremony at the shipyard with hundreds of workers standing in formation in front of the two Type 055s, each decorated with a huge national flag and ceremonial banners. Then the ships were pushed into open waters by several tugboats, the photos showed. The next steps usually are for engineers to test and fine-tune equipment already mounted on the ships and continue installing other devices. Then they will conduct mooring tests and sea trials before the ships are commissioned in the People's Liberation Army Navy. Four Type 055s have now been launched, but none are yet commissioned. The first of the class was launched in late June 2017 at Jiangnan Shipyard in Shanghai, the second in late April at the same shipyard. Type 055 is China's newest generation of guided-missile destroyers. It has a displacement greater than 10,000 metric tons and will be equipped with new types of air defense, missile defense and anti-ship and anti-submarine weapons, according to the Navy. It has 112 vertical launching cells that can fire various kinds of missiles, including China's long-range land-attack cruise missile. Its firepower is thought to be twice that of the Type 052D, the largest and most powerful surface combatant commissioned in the PLA Navy. While the Type 055 is classifed as a destroyer, outside China it would be considered a cruiser as its large size and heavy displacement are comparable to that of the United States' Ticonderoga class cruiser. Li Jie, a senior researcher for the PLA Navy, said the vessel displaces about 13,000 tons. The latest version of the United States' Arleigh Burke class, the largest family of destroyers in the world, has a full displacement of 9,800 tons. South Korea's Sejong the Great class displaces 11,000 tons while Japan's Atago class displaces 10,000 tons. Cao Weidong, a senior researcher at the PLA Naval Military Studies Research Institute, said that compared with other destroyers in the Navy, the Type 055 features stealth design, stronger strike prowess and higher information capacity and will tremendously boost the PLA Navy's long-range operational capability. He also said such ships will greatly strengthen the country's carrier battle groups. charity wristbandswristband comcustom fidget spinnersrubber wristbands custom cheapwristband creationdebossed wristband
HQ-9 air-defense missile is one of the air-defense missiles developed by researchers at China Aerospace Science and Industry Corp's Second Academy. FAN SONG/FOR CHINA DAILY China has become a world leader in air-defense technologies thanks to the hard work and dedication of researchers at China Aerospace Science and Industry Corp's Second Academy, the country's major developer of air-defense weapons systems. Researchers from the academy's Zhang Yiqun Laboratory have been playing a vital role in the development of China's new air-defense missile system by designing its control systems - the brain of any missile. Compared with previous generations of air-defense missiles, the new-generation missile system will have a wider range of targets and be much more technologically sophisticated, taking China into the ranks of just a handful of nations capable of designing and producing such a system. The cutting-edge missile's control systems need to be extremely efficient and accurate, said Wang Mengyi, deputy head of the Second Academy's General Design Department and former leader of the laboratory. Metaphorically put, the mission of these control systems is to guide a needle to fly 1,000 kilometers to pierce the eye of another needle, he said. For researchers from Zhang Yiqun Laboratory, their mission is to turn this seemingly impossible task into reality. Wang said control systems are mainly tasked with working out a missile's best trajectory and making sure it can hit its target. The successful development of China's new air-defense missile system would be unachievable if researchers at the laboratory had failed to design world-class control systems, he said, noting that they adopted new design methods that have reduced design time tremendously and improved missile performance. Wang Xiaodong, a laboratory researcher, said members of the laboratory spent numerous days and nights improving the accuracy of control systems and optimizing the algorithms that are central to them. For example, we worked 10 consecutive days and slept little each day to detect and resolve one extremely rare abnormality because all of us are aware that our nation's air-defense networks can only be reliable if we are meticulous and responsible toward our work, he said. The laboratory, named after Zhang Yiqun, a top researcher at the academy and former head of the laboratory, has been granted 11 National Science and Technology Advancement Awards and 28 National Defense Science and Technology Progress Awards due to its extensive contribution to China's air-defense networks. It has also registered more than 130 defense technology patents. In the laboratory, members of the Communist Party of China play a vanguard, exemplary role, leaders of the laboratory said. They always take the lead in innovating, carry out their assignments carefully, with scrupulous attention to detail, and also display an inspirational level of diligence and devotion toward their work.
