This paper analyzes the advantages and disadvantages of traditional depth charges,the role and position of depth charge weapon in modern naval warfare,and the technical characteristics of 2 foreign advanced depth charges,i.e. 3агон–2 aerial depth charge of Russia and “Sea Spear” rocket homing depth charge of Germany. Then it puts forward a preliminary conception of developing a new all-purpose type of vertical-launched homing depth charge based on foreign advanced technology, and conducts simulation calculations on the combat effectiveness of this new vertical-launched homing depth charge. At the end of the paper,the application prospect of this type of depth charge is depicted.
