Or finally identified might be a better description. Wreck's been known about since the '80s. "A World War One German U-boat has been identified by divers off the coast of Shetland. The SM UC-55 submarine was sunk about eight miles south-east of Lerwick by the Royal Navy in 1917. Divers aboard the Stromness boat Valhalla have become the first to inspect its wreckage. The U-boat had been laying mines in the convoy channel between Orkney and Shetland before being forced to surface due to a technical fault. The wreck site had been been known about since the mid-1980s when scanning equipment picked it up, but Hazel Weaver, the owner of the Valhalla said that 10 years of planning had gone into the dive. "This has been known about for a long time, the question was, is this the wreck what we thought it was," she told BBC Radio Shetland. "After three-and-a-half hours of divers being in the water down to 110m (361ft), they came and confirmed yes this is the UC-55." www.bbc.co.uk/news/uk-scotland-north-east-orkney-shetland-66302352
