April 21st, the Liaoning maritime bureau website issued a circular announcement: announced from 20 to 28, yellow and Bohai parts of the sea to carry out military tasks, any vessel may not enter the sea during the above time. Friends who are concerned about the Chinese navy are all aware that the domestic aircraft carrier (type 002) is likely to have big moves. Since the launch of the first domestic aircraft carrier in April last year, the Asian nations most advanced and advanced main warship has attracted much attention. In March 30th, foreign media reported that the latest photos showed that the scaffolding on the carrier had been dismantled and the phased array radar had been installed, and that the carrier had been prepared for the first sea trial. The notice issued by the Liaoning Maritime Safety Bureau is more directed at this point. What is a sea test? The so-called sea trial is to make the new aircraft carrier ready to go to sea for practical tests. In popular terms, it is pull out and talk again. Although the words are popular, but the content of the sea test is very complex, the most important thing is to see whether the subsystems on the ship are qualified, especially the reliability of the new equipment technology. The sea trial of aircraft carrier is similar to that of other naval ships, and is also divided into captive navigation, factory sea trial and naval acceptance sea trial. Captive navigation is the adaptability training of aircraft carriers and wharfs. The main way is to truly familiarate the crew with all kinds of equipment according to the actual situation of marine operation. It usually takes days for a tethered voyage. The warship carries out continuous operation and operation of the ship to test the operation and operation ability of the ship. The main operational contents of captive navigation include operation and duty training, material condition inspection, emergency handling and equipment training. The manufacturers sea trial is the test of the basic functions of the aircraft carrier. It is organized and implemented by the aircraft carrier manufacturer, and the Navy personnel are involved in and supervised. With the existing information, this sea trial is likely to belong to this stage. Before the manufacturers sea test, we must check and debug all the facilities, parts, communication systems, charge system, air equipment, navigation lights, sewage system, drinking water system, weapon system, elevator and so on. It is confirmed that the installation is correct and can meet the requirements of performance parameters; electronic interference, lighting, and spoke are completed. Inspection of fire noise, air transmission noise, thermal stress, vibration and self noise; flight deck, side wall and bulkhead paint, pipeline shell, label label, etc. must be completed. The major problems identified in the test will be recorded in detail and processed after the return of the aircraft carrier. Take the US Army as an example, the contents of factory testing are very specific, and generally meet the following criteria: first, the major construction problem has been solved. Two, all equipment, accessories, command systems, missiles, artillery and lifting devices have been properly installed and debugged, and meet the requirements of performance parameters. Three, deck and bulkhead spray painting, pipeline shell and label identification must be completed. The four is to complete the examination of electronic jamming, lighting, radiated noise, air borne noise, thermal stress, vibration and self noise. Five is to complete the sonar and other acoustic processing equipment, combat control systems, aviation equipment, navigation lights and sewage, air, drinking water and other certification. In summary, the manufacturers sea test mainly examines whether the various hardware and machinery of the carrier can meet the requirements, while some aircraft can not be tested during the dock. In contrast, naval test is mainly tested and evaluated by naval independent personnel on the system and performance of the aircraft carrier. The sea test project includes the mechanical properties of the carrier, command communication, detection, weapon, air system, ship surface system, navigation equipment, power device test, full power navigation steering and reversing test. Damage control and lifesaving system test, helicopter take-off and landing test, navigation replenishment test and auxiliary system check of air conditioning and so on. The sea trial is first carried out in the offshore area and then further in the farther sea area. The length of sea trial time mainly depends on the quality of design, construction quality, the quantity of the same type of aircraft carrier, the quality of the sea trial personnel, and the guarantee of funds. Generally speaking, the sea trial cycle for the first aircraft carrier of the same type of aircraft will grow for some 1-2 years, and the sea trial cycle of the same type will be greatly reduced. When can we fight? If a domestic aircraft carrier has successfully launched the sea trial, how long will it take to form combat effectiveness? As far as the stage is concerned, the aircraft carrier from the construction to the formation of the fighting power is divided into the following several processes: first, the design stage; second, the platform construction stage; third, the equipment outfitting stage; fourth, the test stage; fifth, training stage, including the single ship training, formation training. Only when the above stage is completed can we say that the formation of the aircraft carrier fleet is beginning to form combat effectiveness. The contents of the design stage and platform construction will not be repeated here. Lets start with the aircraft outfitting. The ship will enter the water after laying the keel from the keel to the completion of the main structure construction and part of the outfitting work. It is commonly known as launching. The homemade aircraft carrier completed this step last April 26th, that is, the process of making the ships that have been supported on the ships platform or in the dock, which have already completed the basic construction work and move into the water. After launching the domestic aircraft carrier, the first important task is outfitting. Outfitting refers to the installation work required after the completion of the main structure of the hull, covering equipment and piping. Ventilation, electrical, iron outfitting, internal outfitting, weapons and so on. To put it simply, outfitting is to install everything except the hull, which is equivalent to receiving a rough room and then fine decoration. According to public reports, the first trial of the Liaoning naval vessel from August 10, 2011 to April 2018 will take part in the actual combat exercise for the first time in April 2018, which lasted for about 6 and a half years. Considering the location of Liaoning ships own emphasis on scientific research and training, as well as the training experience accumulated over the years and the training of a large number of mature warships, we have reason to believe that the progress of the first homemade aircraft carrier will be faster than the Liaoning ship. According to the relevant news issued by the maritime department in April 21st and the completion of the main equipment of the aircraft carrier, the outfitting of the type 002 carrier has been completed, and the commissioning of the equipment is not serious. The beginning of the sea trial should be only a matter of time. From the launching to the sea trial, the Chinese type 002 aircraft carrier took only 12 months or so, compared with the construction speed of Indias aircraft carrier. In addition to the quality advantages of Chinese industrial workers, high efficiency in management and a complete industrial system, there is also an advantage that can not be ignored in the field of military industry: the important system on the aircraft carrier is made in China. It can be developed and installed and debugged by China speed, which saves a lot of time. There are many bright spots for the first domestic aircraft carrier. The domestic new generation of main warship is equipped with more advanced remote detection equipment and more powerful shipborne firepower system. At the same time, a more advanced new generation of combat command system and multi-purpose information processing system are adopted. The domestic new generation combat system integrates all the subsystems of the ship (such as radar, photoelectric, sonar, electronic warfare, helicopter, communication system, navigation weather, power device, NBC ring control and auxiliary machine) into an organic whole, which can fulfill the rapid completion of large volume target detection, tracking, and threat judgment in a short time. Break and allocate weapons and collect and relate target intelligence from various sensors in a short time. Processing, storage and display and auxiliary decision-making, with full automation function from target detection, processing to weapon launching, and target destruction. At the same time, the information cooperative combat system independently developed in China has the ability to receive the information of all nodes in the sea, land, sky and sky, and can quickly deal with all kinds of target information from all kinds of sensors, such as ships, helicopters and other sensors, through the data chain. A potential map for the commander to master the situation. The system can also automatically allocate sensor tasks, track a large number of suspicious targets, coordinate the sea, air and anti submarine (including shipborne helicopters), and the electronic warfare sub system is in the best combat status. In addition, it can exchange information and share resources with fleet and shore command to form a more effective cooperative combat posture. Because the system can analyze and process all land based, sea based and air based radar systems in the system, and effectively integrate with other kinds of sensors and weapons systems, and the previous ships and formation commanders have been analyzed with experience. The arrival of the aircraft carrier sea trial for the 002 aircraft carriers maiden voyage, is also the first launch of the domestic aircraft carrier. It marks a new starting point for the Chinese Navy and even Chinas sea power, which will lead to a bright future for China to build a maritime power.
