Three dimensional net deep-sea "shark hunting" —— Experience of Sino Russian "maritime joint-2021" joint military exercise cross day and night anti submarine exercise Reporter Han Cheng, special correspondent Sun Fei The strong wind swept the sea and set off several meters of white waves; Under the vast ocean, there is an unknown undercurrent. On command, two fixed wing anti submarine patrol aircraft from a domestic airport took off rapidly and flew directly to the exercise sea area through Russian airspace. At the same time, Russian warships, warplanes and other forces launched anti submarine operations simultaneously. A three-dimensional sea and air submarine hunting between the Chinese and Russian navies kicked off. On October 17, the Chinese Participating ship formation searched for submarine targets in the exercise area. Photo by Han Cheng From October 16 to 17 local time, the Sino Russian "maritime joint-2021" joint military exercise turned into a cross day and night anti submarine exercise, which was an important play in the previous Sino Russian maritime joint exercises. In this year's anti submarine exercise, the Chinese and Russian navies respectively invested in various types of main combat equipment, which added a lot to the joint exercise. "Deploy sonar buoys!" Xu Xiaopo, air director and tactical commander of an air service brigade, guided the fixed wing anti submarine patrol aircraft to operate accurately in real time through the command system at the command post of the Chinese Participating ship formation. Moments later, several sonar buoys were successfully thrown away from the engine room, forming a large area of surface submarine search area in the target sea area. As time passed by, the personnel of the command post stared at the dynamics of the large screen. The increasingly fierce wind and waves on the sea have added many unknowns to the submarine search mission. "Immediately launch coordinated anti submarine!" not long after, the command post obtained the information of suspected "enemy submarines", and the commander immediately issued an anti submarine operation order to the formation forces, and the three-dimensional hunting operation was imminent. The rotors roared in the air. At about 11:00 on the 16th, the Nanchang ship's shipborne helicopter took off in an emergency, quickly flew over the surface submarine search area, and used the hanging sonar to conduct a spiral contraction search on the water surface, gradually reducing the target range. "Compared with the fixed wing anti submarine patrol aircraft, the shipborne helicopter has the advantages of fast dispatch speed and strong mobility, and can lock in a more accurate target position." Sun Xiangjie, an air sonar division of a helicopter regiment, told reporters that the sea conditions on that day had reached the critical value, the helicopter swayed violently, and it was necessary to constantly adjust the flight attitude, which made it very difficult to fly and search for submarines. However, complex weather can better hone their combat skills. Chinese and Russian navy officers and soldiers have a common pursuit of actual combat. The more dangerous it is, the more forward it is, and work together to temper their combat style and actual combat ability. Sea warship array. On the afternoon of the 16th, the command post ordered the warships of the formation to deploy sonar and conduct zoning search in combination with the target range screened by shipborne helicopters. After receiving the mission instruction, Zhao Quanyu, vice anti submarine commander of Nanchang ship, quickly implemented the deployment operation at the stern of the ship. Shangshilan Chuanrong reported the measured water temperature, sound velocity and other hydrological elements to the command post. Sergeant Shi Jiabo, the third level, held his breath to identify the target attributes in the noisy ocean sound. At this time, other ships in the formation also complete their operations at the same time. The ship array changes, gradually encircles into a circular mobile formation, and carries out "leapfrog" search on the target. From morning to evening, fixed wing anti submarine patrol aircraft, shipborne helicopters and surface ship formations work closely together to form a three-dimensional search and hunting network, which is pushing towards the target step by step like peeling onions. "Antisubmarine warfare is a recognized problem for navies all over the world, which puts forward higher requirements for the operational capabilities of underwater detection, search and positioning, firepower attack and other systems." Chen Weigong, political commissar of Nanchang warship, introduced that Chinese fighters conducted antisubmarine exercises through Russian airspace for the first time, These new changes benefit from the continuous enhancement of the integration capability of the Chinese and Russian naval system and the in-depth development of the comprehensive strategic partnership of cooperation between the two countries in the new era. In the early morning of the 17th, the command post was brightly lit, and the anti submarine mission continued. The sea waves splashed, and under the undercurrent, the target was still waiting for the opportunity; On the crest and valley, officers and soldiers are waiting for a net (outlook new era)
