Aiming at the inherent safety problem of ammunition under the condition of road transportation, taking the general ammunition of our army as the research object, the safety analysis was carried out from 5 aspects of fuze type, main charge, tactical and technical indicators and service requirements, ammunition packaging and transportation speed by using statistical analysis method. Mortar shells, rocket shells, grenade shells and rifle grenades, grenade launchers and catapult ammunition in light weapons ammunition have low inherent safety and are prone to safety accidents caused by environmental stimulation in the process of transportation, loading and unloading; The countermeasures and suggestions for increasing the transportation safety were put forward from 4 aspects of developing insensitive ammunition, improving the protective performance of packaging, scientifically planning the transportation speed and route, and implementing the loading and unloading specifications. The results show that the analysis provides a basis for ensuring the safety of ammunition road transportation and promoting the efficient support of ammunition.
