TheDefence Diving School is a joint service diver training centre onHorsea Island in Portsmouth Harbour, run by theRoyal Navy.
Construction began in September 1994. It would train around 2000 divers a year.[1]
It opened in September 1995, being previously atHMS Vernon as the Naval Diving School which joined with theRoyal Engineers Diving Establishment.[2][3][4]
It was officially opened in early 1996, with the Sir Charles Pasley pool, by the Second Sea Lord.[5]
At first, training for the Royal Engineers and the Royal Navy was separate. Three years in the RN was required to apply to be a diver, but this policy was dropped in the late 1990s.[6]
The school graduated its first female mine clearance diver on 19 November 2010, 28 year old Lieutenant Catherine Ker. The Royal Navy had changed its admissions policy for women, after theINM had found that women were at no more risk fromdecompression sickness (the bends) than men.[7]
Royal Navy Mine Clearance Divers andBritish Army Divers carry out their basic training at the school's headquarters on Horsea Island, Portsmouth.[8][9]
Royal Navy divers are part of theDiving & Threat Exploitation Group (DTXG).[10] British Army divers are part of theRoyal Engineers or17 Port & Maritime Regiment of theRLC.[11][12] Army divers build, repair, and upgrade Army infrastructure underwater.[13] Navy clearance divers identify and neutralise conventional and improvised explosive threats underwater and on ships and oil rigs.[14]
