Hercules' Tether Cable

Hercules is a Remotedly Operated Vehicle which means that it has to be powered and controlled by a remote control. The controls are used by our skilled ROV pilots aboard the Nautilus. Inside this tether cable, there are 3 copper wires and fiber optics the size of a human hair that send electrical power and pilot commands from the pilot to the Hercules. Hercules also uses the tether cable to attach to its partnering ROV, Argus which then is attached to the ship.
