The first successful sea trial of the Fujian ship, three thought-provoking details
2024-05-10
On the afternoon of May 8, 2024, China's third aircraft carrier, Fujian, completed its first 8-day sea trial and successfully returned to the port. Since its first sea trial, the dynamics of the ship have been closely monitored by various parties, and some of the details are thought-provoking. On the afternoon of May 8th, China's third aircraft carrier, the Fujian ship, successfully completed its first 8-day navigation test mission and returned to the dock of Jiangnan Shipyard. During the trial voyage, the Fujian ship completed a series of tests on power, electrical and other system equipment, achieving the expected results. Next, the ship will carry out subsequent testing work according to the established plan. The Chinese military vessel Weibo and 80000 ton comprehensive media publicly reported that the "Fujian" sea trial began on May 1st and ended on May 8th, lasting for 8 days. In contrast, China's first domestically produced aircraft carrier, the Shandong, began its first sea trial on May 13, 2018 and ended on May 18, lasting six days. According to public information, the displacement of the "Shandong" aircraft carrier is around 60000 tons, while the displacement of the "Fujian" aircraft carrier belongs to the 80000 ton level. This seems to indicate that the duration of the first sea trial is related to the size of the aircraft carrier's displacement, which is five to six days for 50000 to 60000 tons and seven to eight days for 70000 to 80000 tons, but is this really the case? In fact, the test voyage time of aircraft carriers is not directly related to their tonnage size. According to reports from foreign media such as the Daily News cited by Reference News, the latest nuclear powered aircraft carrier of the US Navy, the Ford, has a displacement of 100000 tons. Its first sea trial took 7 days from April 8 to 14, 2017. So, another question arises: the first test voyage of the 100000 ton Ford was one day less than the 80000 ton Fujian. Is this related to the difference in equipment parameters between the two aircraft carriers? This is obviously also a cognitive bias. The duration of military ship sea trials mainly depends on the specific content of the required testing items and various practical problems that arise during the sea trials. Simply put, if there are many testing projects arranged for the sea trial, the time will be longer, and vice versa. At the same time, if significant or even serious problems suddenly arise during the testing of a certain project, it will also change or even suspend the scheduled testing plan, reduce certain scheduled testing projects, and return to the home port in advance. For example, the "Ford" aircraft carrier, which underwent its first sea trial in April 2017, did not undergo its first full ship impact test until June 18, 2021. During this period, many problems, big and small, were exposed, and related tests and plans were constantly delayed. So, what is usually done for the first sea trial of an aircraft carrier? On the afternoon of May 8th, China's third aircraft carrier, the Fujian ship, successfully completed its first 8-day navigation test mission and returned to the dock of Jiangnan Shipyard. During the trial voyage, the Fujian ship completed a series of tests on power, electrical and other system equipment, achieving the expected results. Next, the ship will carry out subsequent testing work according to the established plan. The description of "Electric Power" on the Chinese military ship Weibo is very prominent. In fact, for ships, whether they are aircraft carriers weighing tens of thousands of tons or small boats weighing tens of tons, there are some similarities in the specific projects of the first sea trial. Generally speaking, the first sea trial of a ship requires the following testing items: - main engine navigation test. Including inspection
