Feasibility Analysis of Underwater Submunition Group Defense Against Torpedo

Traditional anti-torpedo weapons are difficult to achieve expected interception effect due to the errors of sonar detection and location. To compensate these errors, a method for deploying submunition group is put forward to intercept a torpedo by the cargo projectiles usually used in the ground guns. In this method, submunition group is deployed in a certain area with certain depth on predicted incoming torpedo trajectory. The submunition distribution is determined by analyzing the damage power of a warhead, and the damage probability is simulated by the Monte-Carlo method. The effects of the factors, such as shooting accuracy, shooting distance, shooting location and submunition number, on the damage probability are analyzed. The assumptions analysis indicates that the application of submunition group to anti-torpedo operation can effectively enhance the damage effectiveness, and this method is feasible in principle.
