Cromhall Diving Centre has sunk an ex Royal Navy decommissioned Mk 8 4.5″ Gun Shield (Turret) – pictured in the process of being submerged.
The fibreglass gun shields were fitted for weather protection on Frigates and Destroyers.
They have now been superseded with more angular gun shields to reduce radar signatures.
The decommissioned shield has been cleaned and sunk for divers to enter, with a dummy gun barrel!
The gun shield has joined shipping containers, a few phone boxes, a number of boats, and an aircraft cockpit.
