PT-109—The Search for the Wreck

<< PREVIOUS | NEXT >>


Equipped with a high-definition video camera, the ROV Little Hercules is lowered by crane from the search ship. In use, the "Herc" remains tethered to the ship by cable.

Piloted by joystick from the search ship's control room, Herc was one of two ROVs used in tandem to visually survey targets identified by sonar.
