Stingray S01E07 - The Man from the Navy

During a training exercise Stingray is fired on by a submarine from the World Navy controlled by Captain Jordon. Despite Stingrays best efforts Tempest fails to shake the artificial missile and it thuds harmlessly into Stingray. On a nearby island an agent for the Aquaphibians makes a report back to King Titan about the successful test. Titan discovers another test is to be conducted and takes the opportunity to set a trap to destroy the Stingray and Tempest. The agents capture the World Navy sub and Jordon, then arms the dummy torpedo.
