Roger Ralph Chapman, CBE (29 July 1945 – 24 January 2020) was a British submariner and businessman. A former Royal Navy lieutenant, Chapman was one of the two survivors of the deepest sub rescue in history in 1973, when his small submersible Pisces III was lifted to the surface from a depth of 1,575 ft (480 m). The founder of the first all-electric ROV company, he later went on to designing subs designed for rescue operations. Using one of his subs, he successfully rescued 7 Russian sailors in 2005 for which he was awarded CBE in 2006.
