"WATTOZZ is an unmanned underwater vehicle. By appearance, it is completely in the form and size of a stingray fish. With this feature, it's unique in the world.
WATTOZZ is controlled cryptographic acoustic sound waves similar to that of animals such as whales dolphins underwater. It has almost the same appearance, size and movement ability with a live stingray fish. With it's silicone-coated outer surface, as well as the ability to stand still on the sea floor in sleep mode and the inner shell covered with the signal absorbing paint, it is impossible for the radars to detect WATTOZZ neither on the sea floor nor on the move.
WATTOZZ, normally used as an observation vehicle, has the ability to transport and explode a bomb by sticking it's target with it's electromagnetic magnets."
