With the increase of anti-submarine depth and distance,the current anti-submarine warfare becomes more and more difficult. In this paper,the development status of anti-submarine weapons and equipment are summarized,and the shortcomings of existing anti-submarine warfare modes are analyzed. This paper deliberates the development status and advantages of supercavitation weapon,puts forward a preliminary assumption of developing an anti-submarine supercavitation ammunition based on gun platform by using supercavitation technology,and conducts simulation calculation on the ballistic performance of anti-submarine supercavitation ammunition. At the end of the paper,the application prospect of this type of anti-submarine ammunition is explicated.
