In view of the fact that amphibious warfare still faces many challenges in practical application, and there is little systematic theoretical research and lack of theoretical guidance for actual combat training, this paper puts forward the theoretical exploration of carrier-based UAV in amphibious warfare in practice. Firstly, the characteristics of amphibious warfare, the development progress and key technologies of carrier-based UAV are analyzed.Then, the future development and application trend of carrier-based UAV in amphibious warfare are analyzed.Finally, the amphibious warfare with intelligent drive, system support and man-machine cooperation as the core force is discussed. The results show that the analysis can provide reference for the construction of carrier-based UAV combat system in amphibious operations.
