A Scot has captured the incredible moment a pod of dolphins appeared to escort a US nuclear sub into a Scottish naval base.
Local Sheila Weir regularly takes photos of the various ships and subs that visit HMNB Clyde at Faslane and was delighted to capture the playful marine mammals as they frolicked close to the nose of the Virginia class submarine.
The nuclear-powered cruise missile-carrying fast-attack submarine was taking part in a routine visit to Scotland that the US Navy says continues to “strengthen the cooperation" between the "United States and the United Kingdom", and the alliance between the NATO allies.
