HMS Orpheus


As a apart of a 4 man team they were preparing to exit from the chamber onto the casing the Submarine entered a patch of fresh water causing it to drop suddenly (a Depth Excursion) from periscope depth.


Although frantic efforts were made by a member of the team to warn them both men transferred from the chambers air supply, now on only on a small bottle (RABA) were probably swept from the casing as the submarine made an emergency surface, now unable to escape negative buoyancy and were dragged down by their equipment, both bodies were later found in over 200ft of water below where the incident had occured.
