Approaching Jiangnan Shipbuilding (Group) Co., Ltd—— From here, the great power ships sail to dark blue ■ Lei bin, hudanqing, yujunwei In a certain sea area in the Gulf of Aden, the sea level was sparkling. The 40th convoy fleet of our navy cut waves and ploughed a magnificent track on the dark blue channel; At this time, in a certain area of the Yellow Sea, a number of new domestic destroyers of the Navy braved the wind and waves and carried out practical training. This day is April 23, 2022, China's naval day. On the Internet, warships have changed their "low-key" in the past and have been on the home pages of various short video platforms. Careful Netizens found that the birthplace of several naval ships was marked with the same place - Jiangnan Shipbuilding (Group) Co., Ltd. (hereinafter referred to as Jiangnan Shipbuilding). To the sea is prosperity, back to the sea is decline; Chasing dreams for a hundred years, casting swords for the country. From a modern industrial pioneer to a modern shipyard, from the famous Jiangnan Machinery Manufacturing Bureau in history to building a national treasure for the Chinese people's navy, Jiangnan Shipbuilding witnessed the rise and fall of the country with every step of development. Here lies the grand dream of making modern China rich and powerful. As the starting point of China's modern industry, they witnessed great changes from the sea. They are known as the "barometer" of the national movement and the "weathervane" of the times. Here, it carries the ambition of new China to become strong in the sea. New China's first submarine, the first frigate, the first generation of space ocean going survey ship, the first domestically made type 055 ten thousand ton destroyer... They have created hundreds of "firsts" in the field of domestic warship manufacturing, and many advanced warships have anchored and set sail from here. New era, new mission, new action. The obvious acceleration of China's naval vessel fleet reflects the valuable spirit of Jiangnan Shipbuilding staff to serve the country. The leaping of Jiangnan Shipbuilding concept and technology proves China's increasingly strong shipbuilding strength. On june28,2017, Nanchang, the first of China's independently developed type 055 10000 ton destroyers, was launched at Jiangnan Shipbuilding. Author's drawings Three generations of ships, thirty years—— "In building missile destroyers of the same type, we have no generation gap with Western powers." This scene is engraved in the memory of every "Jiangnan people"—— On april12,2018, in a certain area of the South China Sea, long whales Lingbo, warships crossing the sea, and the largest marine military parade in the history of new China was grandly held. 48 warships were arrayed with their heads held high, and more than 10000 generals and men were heroic Thousands of miles away, Jiangnan Shipbuilding staff gathered in the auditorium to watch the live broadcast, witnessing a historic moment. "Look, President Xi has boarded the Changsha ship!" After an excited shout, everyone showed a happy smile on their faces and clapped their hands. Changsha warship is a new type of naval warship independently developed by China. It was born in the shipyard of Jiangnan Shipbuilding, and now it is arrayed in the sea, majestic. Many warships were built in Jiangnan during the naval parade. The staff stared at the TV screen and excitedly looked for familiar "faces" and concerned "figures" In the crowd, an elderly man who was nearly seventy years old took off his glasses and rubbed his wet eyes. He is zhangguoxin, chief expert and special engineering director of Jiangnan Shipbuilding. More than 40 years ago, with the horn of reform and opening up, he took the post of ship manufacturing supervision and witnessed a batch of navy ships sailing towards dark blue. The deepest feelings come from the strongest emotions. On the bookshelf of zhangguoxin, there is a history of Destroyer development. Anthonypreston wrote, "no other warship can match a destroyer in terms of its charm, achievements or reputation." Zhangguoxin always remembers that in the 1980s, he went abroad with a delegation and stood on the advanced destroyer to look East and West That feeling deeply hurt the young man's heart. At that time, relevant experts commented: "the gap between China and western developed countries in naval equipment is at least 50 years." "If I can, let me use my 50 years of life to catch up with the 50 years behind the warships!" Zhangguoxin was determined to build the most advanced warships for the motherland. Chasing means giving. Zhangguoxin gave up many hobbies and interests and led his team to "bubble" on the slipway almost every day to carry out experimental research and Research on manufacturing technology. Times, always choose those who are prepared. In 1986, the first generation modern destroyer project of the people's navy was launched. The superior selected the chief constructor, and zhangguoxin, who is young, calm and competent, came to the fore. This is a tough battle. Zhangguoxin said: "there is no 'road map' or 'reference book'. We can only rely on a cavity of blood to brave through difficulties." In those days of hard work, zhangguoxin built the system bit by bit like building blocks. Only analyzing the steel properties, he led the team to accumulate up to 230000 data. Zhangguoxin is not a soldier, but he always said that he "joined the army" in 1986 - from that moment on, his life path was closely tied to the cause of building a strong army. Five years later, China's first generation modern missile destroyer 112 was launched. In the past three years, 112 ships were delivered to the Navy. With the home-made destroyer, the officers and men were full of confidence and piloted it to complete the first round the world voyage in the history of our navy. The 112 warship is therefore known as "the first warship in China" and has been recorded in the history of the development of China's Naval Weapons and equipment. From taking over the mission to the warship's long voyage, the whole process took 8 years. This success made "Jiangnan people" full of confidence. "If we race against time, we will have a chance to win." On the basis of summarizing and combing the experience accumulated in the early stage, zhangguoxin proposed to further improve the shipbuilding efficiency and shorten the cycle. The self pressurization of the "Jiangnan people" has resulted in the overall acceleration of the upgrading of the people's navy ships—— The Harbin ship crossed the Pacific Ocean, the Haikou ship headed for the Gulf of Aden, and the first 052d destroyer Kunming ship was listed... Zhangguoxin personally participated in the construction of the third generation of the sixth type ship. As soon as possible, they delivered two generations of four ships in five years. On June 28, 2017, Nanchang, the first 10000 ton destroyer of type 055 independently developed by China, was launched. The ship has successively broken through a series of key technologies such as the overall design, information integration and final assembly construction of large ships, equipped with new air defense, anti missile, anti-ship and anti submarine weapons, and has strong information perception, air defense, anti missile and sea attack capabilities, marking that China's Destroyers have reached the world's first-class level. On that day, Zhang Guoxin, who has always been prudent, announced loudly: "we have no generation difference with Western powers in building missile destroyers of the same type. We have used 30 years to close the gap of 50 years!" The compressed time is engraved on zhangguoxin's face. With white temples and clearly carved wrinkles on his forehead, zhangguoxin was an ancient and rare old man at this time. On the Bank of the Huangpu River, the rising sun spurted out from the sea level. Watching warships sailing towards dark blue, zhangguoxin felt that he was still the passionate young man of that year. Qianminjun (third from the right), field engineer of Jiangnan Shipbuilding general assembly department 1, discussed business work with his colleagues. Author's drawings In a word, pursue all your life—— "Seeing these warships is like seeing your own children" Spray splashes in a sea area in the Gulf of Aden. "Machine guns stop fire!" With the command of the commander, a series of flames shot out of the warship's machine gun. At this time, not far away, several pirate ships were eyeing the merchant ships, waiting for the opportunity to attack. Seeing the Chinese navy in full readiness, the pirate ship fled in a hurry. In 2008, our navy went to the Gulf of Aden and the waters off Somalia for the first time. In the formation, Haikou ships and Wuhan ships are all from Jiangnan Shipbuilding. At that time, it was the most rampant period of piracy, and the relevant sea areas were jittery. In order to ensure the safety of passing merchant ships, the formation warship has set a record of 124 consecutive days of sailing without replenishment at the wharf, and the equipment and equipment on the warship still maintain a very high intact rate. The confidence of the officers and men to successfully complete the escort task stems from Jiangnan Shipbuilding's extreme pursuit of warship quality. In the eyes of military enthusiasts, the value of a warship is often measured by the displacement of tons. In the eyes of Jiangnan Shipbuilding staff, "ton" is definitely not their most familiar unit of measurement. Chief technician chenzhinong's commonly used unit of measurement is "silk". One thread, only 0.01 mm, equivalent to 1/6 of a hair. Chenzhinong is responsible for the installation of the ship's power plant. Tens of thousands of parts have to pass through his hands. His standard is that the installation details of each part must be "watertight" - even a small gasket must have three points of positioning. For welding technician chenjingyi, his world is sometimes very small: he is the first person in China to successfully weld 5mm thick stainless steel pipe by MIG welding. He said: "welding is an 'exquisite and wonderful art', and we must see the true chapter in the subtle." "The bigger the project, the more it tests the details." "Jiangnan people" uphold a belief that warship manufacturing is linked to the construction of naval combat effectiveness. A small gasket or a fine weld joint may lead to unpredictable consequences. This belief reflects the outstanding pursuit of "Jiangnan people" for quality. In the 1980s, the older generation of "Jiangnan people" took the construction of first-class ships as their goal and shouted the loud slogan "no gold award, no Jiangnan factory". This sentence has become the lifelong pursuit of many employees—— In order to practice his hand feel, chenjingyi hung the brick on his wrist and practiced repeatedly in a welding posture. His colleagues often said that "he is like a sculpture". After years of accumulation, his hands were scarred and it was difficult to find a piece of smooth skin. Technician lijinhua has been working as a pyrotechnic worker for nearly 40 years. His work has no teaching materials and depends entirely on his eyes and hands. He can distinguish the current by listening to the sound 20 meters away. He can judge the temperature by looking at the flame from a distance: "at 950 ℃, the flame is red and yellow; at 1100 ℃, it will flash a light yellow. Finally, with a touch of white in front of him, it will reach 1300 ℃." From the stories they tell, we can feel the power of still water. They are not like the surging Yangtze River or the vast sea, but in the trend of the times of naval construction, they are like surging waves, boosting the Chinese navy to the deep blue. On april23,2019, a grand maritime parade to celebrate the 70th anniversary of the founding of the people's navy was held in Qingdao. In the spotlight, the destroyers piloted by Nanchang, the first domestic type 055 ten thousand ton destroyer, came from the waves with great momentum. Many of these warships came from Jiangnan Shipbuilding. On that day, chenjingyi was busy in his workshop. After work, he browsed the relevant news and wrote this sentence in the message desk: "seeing these warships is like seeing their own children. After being baptized by the sea, they are more vigorous and have more extraordinary temperament..." A memory, four generations of youth—— "The youth of generations of military workers is surging with the power to create brilliance" The Yangtze River surges all the way. It cools down gently at the mouth of the Huangpu River and enters the sea calmly. On Changxing Island in Shanghai, a statue stands majestically -- he is wangrongyu, a submarine engineer. Few people know that the first submarine of new China built by the Chinese themselves also sailed quietly from Jiangnan Shipbuilding. In that year, wangrongyu led the team to carry out many sea trials, which made great contributions to the development of the submarine force of new China. However, what does not match with his outstanding achievements is that there are few online introductions about Wang Rongyu. In Jiangnan Shipbuilding, such a phenomenon
