The basic theory of sampling inspection is studied，the reliability indexes of the torpedo and quantitative indexes in sampling inspection are analyzed. By applying probability theory and mathematical statistics， a scheme based on reliability and sampling inspection is proposed；by analyzing operating characteristic curve and using hypergeometic distribution，a special model of weapon equipment reliability sampling inspection is set up. The feasibility of the scheme is tested by actual calculation，this solution can provide theoretical foundation for equipment acceptance in testing，producing and repairing.
