Roger Chapman: The Deepest Sub Rescue

Submarine rescue before 1973 faced multiple challenges such as lack of technology advancements and specialised equipment.

Additionally, there were no dedicated submersibles or remotely operated vehicles (ROVs) specifically designed for submarine rescue missions. This meant that rescuers had to rely on improvised methods using available equipment, which often proved inadequate for efficient and safe operations.

Roger Ralph Chapman, CBE (29 July 1945 – 24 January 2020) was a British submariner and businessman who formally served as a Royal Navy Officer. Chapman alongside his fellow submariner, Roger Mallinson, were the two survivors of the deepest rescue in history in 1973, when their submersible, Pisces III, was lifted to the surface from a depth of 1,575 ft (480 m).
