A7 Project

The SHIPS Project divers are returning to HM submarine A7 in 2026 to see how the submarine has changed since their first survey of the site in 2014.

SHIPS volunteer divers will return in 2026 to repeat the assessment survey and to record any changes the condition of the hull after 12 years.  We will create a digital 3D model of the submarine and study the marine biology living on and around the hull.  We will also measure the thickness of the iron hull plates again to see how much more they have corroded.


  • Document the story of the loss of the submarine
  • Undertake a detailed assessment of the wreck site
  • Undertake a condition assessment of the submarine
  • Raise public awareness about the story of the submarine and its loss
  • Investigate the cause of the loss of the submarine
  • Create an archive of information about the submarine
