THIS GIVES NEW MEANING TO THE PHRASE, "You'll never even hear them coming."
Torpedoes and the Next Generation of Undersea WeaponsExactly how is this accomplished? It may have something to do with this description: "Using supercavitation techniques, the torpedo becomes an underwater missile… the water near the tip of the projectile – or torpedo – literally vaporizes from the high speed, producing a pocket in which to "fly" the weapon underwater."
Anti-torpedo torpedoes will provide our future platforms with an additional defense capability. Their primary mission is to destroy incoming torpedo threats that may have gotten through a countermeasure field. Based on technology under development at ONR, a 6.25 inch-diameter self-protection weapon is under study for the defense of surface ships and submarines using supercavitation technology. The Advanced High Speed Underwater Munition (AHSUM) program has already demonstrated the effectiveness of such high-speed underwater bullets. Fired from an underwater gun, these projectiles have successfully broken the speed of sound in water (1,500 meters per second), bringing their future application much closer to reality.
