U.S. navy has taken a different approach to the underwater weapons by making the most of the acoustic energy. A recent patent filed by them has revealed of a new powerful weapon that makes use of sonar to generate “acoustic remote cavitation’ that could destroy torpedoes, mines, and many other hinders. The acoustic source and target can be located in unconfined underwater space and at a distance of at least 100 m apart. The underwater cavitation could be used in superfast sub and missiles. The idea is pretty different i.e. using acoustic energy instead of any bombs or missiles to destroy the targets. It is no doubt a new pin on the idea of underwater weapons. Via: DangerRoom
