The battlefield practices such as the Syrian War and the Naqa War have shown that unmanned combat forces represented by UAV have become an important component of the future joint combat force system, playing an increasingly prominent role as efficiency multipliers. Especially in recent years, military powers such as the United States, Britain, and France have made swarm collaboration an important development direction for drone warfare. This article first discusses the connotation and mechanism of the application of new unmanned aerial vehicle swarms in foreign countries. Then, focusing on the air to air coordination, air to ground coordination, and air sea coordination equivalent combat modes of unmanned aerial vehicle swarms, typical application scenarios of foreign military unmanned aerial vehicle swarms will be studied. Finally, the key conditions for the collaborative operation UAV swarms were studied, providing important technical support for subsequent large-scale construction and application in the sea and air.
