Many UAVs have limited flight time, while long-endurance unmanned aerial vehicles (UAVs) can achieve longer flight times and have the potential for continuously performing tasks, such as monitoring disasters, long-range telecommunication relay, internet network services, aerial surveillance, etc. Due to the efficiency requirements in their design, long-endurance

UAVs not only demand more advanced energy management methods, but also pose great challenges in terms of control, communication, and development. The study of long-endurance UAVs has faced major challenges with increasing efficiency requirements. Thus, it is an urgent need for the latest developments to be pursued.

This Special Issue welcomes original research and review articles that discuss control theory, communication, applications, and implementation in relation to long-endurance UAVs. This Special Issue aims to help solve the problems encountered in theoretical and practical applications for long-endurance UAVs.
