Abstract: Methods of integration analysis are used to analyze relationships in information sharing, functional support and infiltration, et al. that exist between fuse and firepower control system, from the point of view of the functional system of a whole ammunition-weapon system. The concrete adapting & matching relationship in those aspects such as the task, function, information and structure are summarized between these two subsystems. The viewpoint suggests that it depends deeply on the design of adapting and matching in the function, information and structure between the fuse and other subsystems of the weapon system, thus much expanding the traditional function of fuse. The factor of adapting & matching design is put forward.
