Defense Strategy for Suicide Unmanned Surface Vessels Based on Sea and Air Unmanned Clusters

The recent use of unmanned surface vessels(USVs) in the Russia-Ukraine conflict has received much attention. To prevent the attacks of suicide USVs, the idea of using unmanned platforms to counter USVs was followed, and a new concept of preventing the attacks of suicide USVs by using low-cost platforms such as USVs and unmanned aerial vehicles(UAVs) featuring “collaborative enabling, autonomous control, and agile response” was proposed. Multiple lightweight USVs, UAVs, and unmanned platforms with simple interaction and autonomous decision-making capabilities were used. By analyzing the capabilities of typical suicide USVs, key technologies such as sea and air collaborative task assignment and planning and cross-platform collaborative reconnaissance and positioning were studied, so as to build a new unmanned reconnaissance and defense system. This system not only ensured all-weather and quasi-real-time coverage of key defense areas but also achieved agile confirmation and immediate response to invading suspicious targets. Furthermore, it expanded the defense depth of high-value targets and established multiple layers of defense against the attacks of suicide USVs in clusters.
