A look around the Royal Navy's new aircraft carrier
Work is under way on the Royal Navy's second new aircraft carrier, the Prince of Wales, at the BAE Systems yard on the River Clyde.
BBC Scotland has had a look around the carrier's forward island and bridge before it is moved to the Rosyth dockyard where final assembly is due to begin later this year.
The Prince of Wales' sister ship, HMS Queen Elizabeth, was officially named in July.
