海军航空兵反潜实战训练 “有人+无人”织就空中反潜网

Since the advent of submarines, they have posed a significant threat to surface vessels due to their stealthy maneuverability. Thanks to their strong concealment capabilities, anti-submarine warfare has long been a major challenge for navies around the world. In the years of mutual hunting between hunters and prey, air forces have become one of the important forces in anti-submarine operations. With the gradual deployment of unmanned equipment into practical training, this confrontation between the sky and the deep sea is ushering in new changes.

Recently, a certain unit of the naval aviation conducted a realistic anti-submarine training exercise, where anti-submarine patrol aircraft teamed up with a certain type of drone in a specific maritime airspace. Using the "manned + unmanned" model, they constructed a new aerial anti-submarine network, forming a seamless operational loop of "search—track—strike." What kind of operational effectiveness can the combination of anti-submarine patrol aircraft and drones enhance?

Formation Strike: "Manned + Unmanned" Coordination, Weaving an Aerial Anti-Submarine Search Network

In the recent realistic anti-submarine training conducted by a certain unit of the naval aviation, the anti-submarine patrol aircraft and a certain type of drone took off to form a network in the mission sea area. The combination of manned anti-submarine patrol aircraft and drones created an aerial anti-submarine search network with a mix of high and low capabilities, covering both long and short distances:

Military commentator Fu Qianshao from China Voice's "Fengxian Liaowang": From the entire operational process, the unmanned drone conducts detection of underwater targets and accurately locates them. Then, the relevant data is transmitted to the manned anti-submarine aircraft, which carries anti-submarine weapon systems to precisely attack the underwater targets. The unmanned anti-submarine drones and manned anti-submarine patrol aircraft, including fixed-wing and helicopters, constitute a new anti-submarine system. The unmanned anti-submarine drones have become the "loyal wingmen" of the manned anti-submarine patrol aircraft.

Participating pilots in the training expressed that "manned anti-submarine patrol aircraft are limited by the physiological limits of pilots and endurance time, making it difficult to achieve large-scale, uninterrupted monitoring of underwater targets. Deploying drones for close inspection at critical stages helps to better leverage the rapid response advantages of the 'manned + unmanned' formation."

Bridging the Gap: Long-Endurance Unmanned Platforms Expand Search Boundaries

Military commentator Fu Qianshao believes that despite having advanced detection equipment, manned anti-submarine patrol aircraft face unavoidable shortcomings in terms of air time and the sustained working capacity of crew members during combat missions. Long-endurance drones can effectively fill these gaps:

Military commentator Fu Qianshao from China Voice's "Fengxian Liaowang": If we use the previous combat methods, searching a certain sea area with anti-submarine patrol aircraft requires a large search range and consumes a considerable amount of time. If fuel runs low, the anti-submarine patrol aircraft must return to base for refueling before continuing, or multiple anti-submarine patrol aircraft must conduct continuous searches over a certain sea area, which incurs high costs. At the same time, it is often difficult to achieve rapid detection and rapid attack of targets. With unmanned anti-submarine platforms, both the range and duration of aerial searches have significantly improved.

Division of Labor in Detection: Drones Undertake Magnetic Detection Tasks, Mitigating Low-Altitude Risks

The magnetometer searches for submarines by capturing changes in the magnetic field. To achieve precise detection, anti-submarine aircraft must fly at low altitudes, which imposes significant safety pressures on the crew. In this operational method, drones equipped with magnetometers conduct low-altitude magnetic searches, effectively avoiding personnel risks and ensuring the safety of manned flights, forming an aerial anti-submarine search network that combines wide-area sonar buoy screening with precise verification by drones carrying magnetometers.

△ Magnetic detection requires low-altitude flight, increasing the safety risks for the platform itself.

Military commentator Song Xiaojun from China Voice's "Fengxian Liaowang": Simply put, sonar buoys are used to broadly assess the approximate location of submarines. Ultimately, manned anti-submarine aircraft equipped with magnetometers lower their altitude to determine the exact position of the submarine. The limitations in adverse weather and sea conditions are significant. Now, using drones to carry magnetometers essentially eliminates those limitations. They can still fly in high sea conditions and adverse weather, and the number of drones can also be relatively large. If we have sonar buoys in a certain sea area that detect submarine activity, we can quickly deploy many drones (for magnetic detection), greatly improving the efficiency of precise submarine localization.

As this aerial anti-submarine training exercise enters a critical phase: the drone maintains stable tracking, firmly locking onto the target submarine's trail. Upon receiving the information relayed by the drone, the anti-submarine patrol aircraft swiftly adjusts its course, joins the bombing route, and prepares to attack the target submarine. The division of labor is clear, and the cooperation is tacit, effectively simulating an attack on the target submarine, forming a seamless operational loop of "search—track—strike."

Talent Support: Professional Military Personnel Backing the Implementation of New Tactics

Military commentator Song Xiaojun believes that synchronizing technology and personnel reserves is essential to rapidly develop combat capabilities for the "manned + unmanned" model.

Military commentator Song Xiaojun from China Voice's "Fengxian Liaowang": Anti-submarine warfare requires a very large weapon platform and human resources. Because the operational area is vast and continuous 24 hours a day. China has implemented reforms for professional military personnel, training a large number of drone pilots. Among these drone pilots, we have enough specialized personnel with relatively long service times, significantly enhancing our unmanned anti-submarine capabilities.

Trend Outlook: The Integration of Manned and Unmanned Forces Reshaping Future Aerial Anti-Submarine Models

Military commentator Fu Qianshao points out that this new anti-submarine tactic, which integrates equipment advantages and personnel strengths, is likely to become a new trend in the development of future anti-submarine operations.

Military commentator Fu Qianshao from China Voice's "Fengxian Liaowang": The anti-submarine combat model of the People's Navy aviation has seen rapid development and upgrades in recent years. The mutual cooperation between manned and unmanned aircraft will enable more precise detection of enemy underwater targets, including manned submarines and unmanned underwater vehicles, over a considerable maritime area. When necessary, precise strikes can also be conducted, which can be said to change the future anti-submarine combat model.
