Abstract : A coaxial strain cable tows a tube-like net-containing pod behind a ship. Sensors on the pod carried beneath the ships wake detect incoming torpedoes and supply detection data via the coaxial cable to a shipboard processor. Processor commands return via the cable to a pod motor to drive rudders and maneuver the pod into the torpedo path. Drogue and main parachutes packed in the pod are released into the path by other cable-carried commands. Power for the motors and a 'chute release mechanism also is supplied through a cable. The main 'chute is formed of a low drag aramid fiber mesh strong enough to arrest the torpedo. Preferably, explosives carried by the 'chute destroy it. (Author)
