The U.S. Navy certainly doesn't seem to have any shortage of unconventional weapons in development, but it looks like it still has plenty more ideas on its plate, with a recent patent revealing yet another new weapon that takes a slightly different path towards its target. While this one is unconventional, it certainly doesn't appear to be non-lethal, employing sonar to generate what the Navy describes as "acoustic remote cavitation," which can supposedly destroy torpedoes, mines, and any other "undesirable objects" in its path. What's more, the Navy says that can be done from a distance of up to one kilometer away, which is apparently far greater than other similar examples of the technology. Less clear, however, is how the Navy plans to deal with the seemingly inevitable swarms of irate dolphins set on enacting some revenge.
