Anti-torpedo torpedo(ATT) is a kind of hard kill weapons that can actively search for and intercept torpedoes with different guidance systems, and the high damage probability leads it to be an important direction in the field of underwater defense in various countries. In this paper, torpedoes of different types of guidance, and the features of different torpedo defense methods are concluded. The development history of the ATT is presented as well as the status of ATTs of different countries. Finally, the operational use of the ATT is studied. The intercept probability of the ATT with different interception trajectories/performance is analyzed by simulation study.
