The Defence Diving School is a joint service diver training centre on Horsea Island in Portsmouth Harbour, run by the Royal Navy.
History Construction began in September 1994. It would train around 2000 divers a year.Navy News September 1994, page 7
It opened in September 1995, being previously at HMS Vernon as the Naval Diving School which joined with the Royal Engineers Diving Establishment.
It was officially opened in early 1996, with the Sir Charles Pasley pool, by the Second Sea Lord.Navy News March 1996, page 9
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.Navy News March 1999, page 20
Female divers 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 the INM had found that women were at no more risk from decompression sickness (the bends) than men.
Function Royal Navy Mine Clearance Divers and British Army Divers carry out their basic training at the school's headquarters on Horsea Island, Portsmouth.
Royal Navy divers are part of the Diving & Threat Exploitation Group (DTXG). British Army divers are part of the Royal Engineers or 17 Port & Maritime Regiment of the RLC. Army divers build, repair, and upgrade Army infrastructure underwater. Navy clearance divers identify and neutralise conventional and improvised explosive threats underwater and on ships and oil rigs.
