HMS Unity (N66)

Unity was built by Vickers Armstrong, Barrow-in-Furness. She was laid down on 19 February 1937 and was commissioned on 5 October 1938.

At the onset of the Second World War, Unity was a member of the 6th Submarine Flotilla. From 26–29 August 1939, the flotilla deployed to its war bases at Dundee and Blyth.[1] She served in home waters in the North Sea, making a failed attack on the German submarine U-2.[2]

She rescued the survivors of Dutch fishing vessel Protinus on 25 March 1940.[3]

Unity sailed from Blyth on 29 April 1940 to patrol off Norway, where she collided with the Norwegian ship Atle Jarl, sinking five minutes later.[4] Two members of her crew, Lieutenant John Low and able Seaman Henry Miller, gave their lives by remaining behind in the flooded control room so that their shipmates could escape from the sinking vessel.[5]

The wreck is accessible by technical divers, lying at a depth between 48 and 55 metres (157 and 180 ft)[6] off the Farne Islands.[7]
