Abstract In view of the shortcomings of present integrated support design of weapon equipment, and the demand of integrated support design of weapon equipment, a big data system oriented integrated support design of weapon equipment is researched in this paper. Through the study of the overall architecture of big data system of integrated support design, big data integration and storage of integrated support for life cycle, and big data mining of integrated support, a general frame plan including big data integration and storage, big data mining, network infrastructure support environment is formed. The research can guide the construction of big data system.
