In response to the problem of outdated quality supervision methods in traditional military inspection technology, this article analyzes how military representatives carry out digital military inspection business based on MBD (Model Based Definition) during the product design stage. Sort out the outputs and corresponding military inspection points during the product design stage, and conduct research on the content, methods, and objects of military inspection. The results indicate that developing digital military inspection technology based on MBD during the product design phase can enhance the military representative’s ability to supervise equipment quality, adapt to the MBD based equipment development system, and is the future development direction of military inspection technology.
