Unmanned combat is the main form of future intelligent maritime confrontation activities, and the maritime unmanned combat information system is an important support for maritime unmanned combat. In view of the needs of the future maritime unmanned combat, the concept of the maritime unmanned combat information system is expounded, and the general situation of the system development is sorted out. On this basis, the characteristics and advantages of the maritime unmanned combat information system are analyzed, and the force composition and typical pattern of the system's combat use are initially conceived, which can be used as a reference for future system construction and development.
