In recent years， unmanned aerial vehicles have become an indispensable and important weapon in modern warfare， and the offensive and defensive confrontation system covering unmanned aerial vehicle systems has become one of the basic characteristics of modern warfare. Studying the survivability problem of unmanned aerial vehicle systems under strong denial conditions has important application value for future battlefield confrontation. This paper analyzed the challenges faced by combat unmanned aerial vehicle systems in the physical， electromagnetic， and information domains and gave targeted strategies to cope with different denial conditions. The combat scene， combat configuration， and movement tactics were proposed for unmanned aerial vehicle systems under strong denial conditions. The key problems related to survivability were studied， including the bifocus random walk algorithm of relay swarm， the secondary planning technology of denial space path， and the service-oriented architecture technology of intelligent edge accusation center. By optimizing the overall design of the combat system， the survivability of unmanned aerial vehicle systems under strong denial conditions can be effectively improved to cope with the complex combat environment of future battlefields.
