In order to solve the problems of difficulty in reuse of the combat test data resources of our army conventional weapons and difficulty in exerting its value, a data reuse model and method are proposed. Through the analysis of the characteristics and classification of army conventional weapon combat test data, the mode and method of data reuse are discussed, and countermeasures and suggestions for accelerating the development and construction of data reuse are proposed. The research can provide a reference for further strengthening the reuse of test data and advancing the construction of weapon equipment data engineering.
