The Robot Sea Probe was used by WASP for automatic patrolling of the ocean.
The Robot Sea Probe was a new technology developed by the WASP that was supposed to autonomously patrol the ocean to help reduce the number of manned patrols needed. However, during its inaugural voyage, it mysteriously disappeared while on patrol. When Stingray went to investigate, the crew was captured by a pair of survivors from a volcanic city desperate to escape.
- The same Robot Sea Probe was used as a radio marker from Hepcat in "Raptures Of The Deep".
