A nuclear-powered submarine that ran aground off the coast of Skye is making its way back to base for further checks.
HMS Astute had become stuck during sea trials on Friday in a channel between the island and the Scottish mainland.
The vessel - which is the UK's most powerful attack submarine - remained on view from 8am until the tide turned in the evening when it was freed by a tug.
The Ministry of Defence said checks of the sub's rudder, which is thought to have become stuck on a shingle bank, were carried out in deeper water.
Astute will now return to base at Faslane on the Clyde for further checks.
An MoD spokesman said: "Surveys of Astute have now been completed and she will proceed to Faslane under her own power. She is being escorted by tugs and HMS Shoreham."
The Royal Navy launched a service inquiry into why the 100m-long submarine ran aground in the channel between Skye and the Kyle of Lochalsh.
The vessel is understood to have strayed several hundred yards outside the safe sea lane marked on Admiralty charts.
The MoD said the investigation into the incident would be "full and thorough".
The investigation will also consider if any crew were negligent and the submarine's skipper, Commander Andy Coles, could find himself in front of a court martial.
