The A7 Project - An investigation of HM Submarine A7

Author(s): Peter Holt

Year: 2015


January 2014 was the 100th anniversary of the loss of the Royal Navy submarine A7, sunk during a training exercise off Plymouth, England.  All contemporary salvage attempts failed and the submarine was abandoned on the seabed and forgotten, but the wreck was rediscovered by sports divers in 1981.  In 2001, problems with sports divers removing parts of the submarine prompted the UK Ministry of Defence to designate the site under the Protection of Military Remains Act and all diving was banned.

In 2014 the SHIPS Project team were granted a license to dive and record the remains of HMS/M A7, the first license granted for an MOD Controlled site.  The A7 Project is a non-intrusive investigation of the submarine which includes research in to her life and loss, a high resolution geophysical survey of the area, a detailed hull condition assessment and a comprehensive programme of outreach and publications.
