Abstract:From the perspective of submarine anti-torpedo defense, this paper mainly introduces and analyzes the tactical background, the development status of countermeasures and the future development direction of submarine anti-torpedo defense. In view of the torpedo and anti-submarine threat faced by submarines, this paper summarizes the characteristics of submarine active and passive defense technologies, focusing on the construction of network centric, multi-level, multi-platform, and intelligent integrated defense system is considered and envisaged, which provides an important reference value for the development of submarine underwater anti-torpedo defense technology and system construction
