Abstract
A method and apparatus for detecting and deterring underwater threats is provided that uses numerous anodes and sensors around a ship or other waterborne structure to monitor for intruders and issue electrical shocks to the intruders in increasing amounts to deter sabotage. The underwater detection and deterrent system would provide an alarm and the approximate location of the intruder when the electrical field changes in response to the intruder. The system is capable of providing a lethal electrical shock to the intruder if necessary.
