Abstract:

An interdiction system to be placed upon the floor of the ocean includes a target detection and classification system which is cooperatively connected to a hollow enclosure containing a predetermined volume at one atmosphere or less pressure. Upon target acquisition and classification, the detection and classification system actuates a mechanism to rupture the wall of the hollow enclosure. The resultant implosion caused by the ambient ocean pressure creates a high intensity shock wave in the vicinity of the system to damage the intruding vessel. The instant invention overcomes the disadvantages of the prior art by providing a shock wave producing system which is lethal at pelagic depths but relatively harmless in a surface environment. This system employs a frangible wall container having a predetermined volume at low atmospheric pressure which is moored on or near the ocean bottom. A target detection and classification device is attached to the frangible vessel and ruptures it when a predetermined target signal has been acquired and classified.
