Just when you thought it was safe to go back in the water …
The US Navy recently demonstrated a prototype underwater surveillance device known as Ghost Swimmer. Designed to blend in with marine life, the drone looks and swims like a shark. Weighing just under 100 pounds, the Ghost Swimmer is approximately five feet long, so it’s no Great White. Even so, videos released by the Office of Naval Research show it to be eerily life-like.
The Ghost Swimmer may be used for intelligence gathering purposes as well as potentially taking the place of the trained Bottlenose dolphins currently used by the Navy to detect underwater mines. The device can be controlled remotely via tether, or it can be programmed to dive solo and return to the surface to transmit information.
In this video published by Wired, you can see how life-like the Ghost Swimmer appears.
