A sick crewman has been airlifted from a Royal Navy nuclear submarine taking part in a major training exercise off Cape Wrath in Sutherland.
The Stornoway Coastguard helicopter was called to assist HMS Triumph on Thursday evening.
The casualty was airlifted to Raigmore hospital in Inverness where he was being treated for a medical complaint.
HMS Triumph is taking part in the bi-annual exercise Joint Warrior along with other Nato forces.
The Trafalgar class nuclear-powered submarine usually has a crew of 130.
It will join ships from Germany, Belgium, Netherlands, Norway, Poland and Estonia to carry out mine hunting training off the Sutherland coast.
The exercise will run until 15 October.
