Guided by precise support， this paper proposes the concept of integrated support design of weapons based on health management and analyzes the relationship between precise support and health management of weapons. The traditional design process of integrated support is summarized according to the current design steps of integrated support of weapons， and its shortcomings in the context of demand for precise support are proposed. Finally， this paper proposes the design method and process of integrated support based on health management， and the traditional design process is compared with the design process based on health management， which provides support for the subsequent integrated support design of weapons.
