A team of divers have discovered a wartime torpedo lying on the Scapa Flow sea bed in Orkney.
The divers were carrying out a survey for Orkney Harbour on Saturday when they made the discovery.
The find was reported to the Shetland Coastguard who have now contacted the Explosive Disposal Unit of the Navy’s Northern Diving Group at Faslane.
Bomb disposal are due to arrive today or tomorrow to deal with the device.
A spokeswoman for Shetland Coastguard said the torpedo appeared to be about 70 years old andwas lying in about 100 feet of water. It was not near a wreck and a safety warning was being issued to divers.
Scapa Flow was a major anchorage and base for the British fleet during both world wars.
Following the German defeat in WWI, 74 ships of the Kaiserliche Marine’s High Seas Fleet were interned in Gutter Sound at Scapa Flow pending a decision on their future in the peace Treaty of Versailles.
On 21 June 1919, after nine months of waiting, Rear Admiral Ludwig von Reuter, the German officer in command at Scapa Flow, made the decision to scuttle the fleet.
At least seven of the scuttled German ships, and a number of sunken British ships, can be visited by scuba divers.
During WW11, Scapa also saw one of the iconic attacks of the conflict.
On 14 October 1939, under the command of Günther Prien, U-47 penetrated Scapa Flow and sank the battleship HMS Royal Oak anchored in Scapa Bay. Of the 1,400-man crew, 833 were lost. The wreck is now a protected war grave.
