Development Concept of a Shipborne Supercavitating Projectile Interception System for Counter-UUV Defense

The rapid advancement of Unmanned Underwater Vehicle (UUV) technology has led to its growing application in military reconnaissance and underwater combat, posing severe challenges to conventional underwater defense architectures. This paper investigates the current development status of international supercavitating projectile weapons and assesses the counter-UUV defense requirements for surface combatants. It further examines the technical superiority and operational potential of supercavitating projectiles in countering UUV threats, proposing an integrated system architecture for shipborne supercavitating projectile-based counter-UUV defense systems. Critical technological components of each subsystem are analyzed. By leveraging ultra-high speed, near-instantaneous response, and enhanced lethality, supercavitating projectiles demonstrate the capability to overcome bottlenecks inherent in traditional underwater interception methods, thereby offering a transformative paradigm for future undersea warfare strategies.
