Royal Navy submariner trainees have been presented with a new badge.
The first trainees to be given the new training dolphins were students of the current Submarine Qualifying Course at HM Naval Base Clyde.
Previously, those joining the Submarine Service had no insignia recognising them as trainees.
Commodore Jim Perks, Head of the Royal Navy Submarine Service, presented the students with the new badge and said the training dolphins "recognise the progression" of the trainees.
"The introduction of the submarine training badge marks an important step in the career of those choosing to serve as submariners," he said.
"Training dolphins will increase our service's visibility within our training establishment and potentially increase the number of volunteers."
First presented in the 1950s, the Gold Dolphin badge has been the mark of a fully-qualified submariner and the current badge, which depicts two dolphins and an anchor, was introduced in 1972.
The new training dolphins are similar in size and design but are black in colour.
As the new badge was presented at Faslane, trainee submariners across the UK were also receiving their training dolphins.
All new entry officers and ratings on streaming submarines at Britannia Royal Navy College and HMS Raleigh will be eligible to wear the badge.
