Research on Anti-Torpedo Torpedo Interception Strategy of Surface Ship

As the capability of torpedo intelligence continues to improve, anti-torpedo torpedoes (ATTs) have become a major research focus in many countries, where the interception strategy directly affects ATT interception probabilities. In this study, four ATT models of rough-position, head-on, direct and current-location interception are established to defend against incoming torpedoes. The defense strategy is divided into four processes: long-range, medium-range, close-range, and near-boundary. Based on a simulation of the ATT interception probability under different situations, an optimal interception method of the ATT at different ranges is then obtained, and an optimal interception strategy for surface ships to defend against incoming torpedoes is proposed, thus providing a significant means of improving survivability of surface ships.
