Work is under way to transfer an 11,000 tonne section of aircraft carrier from its construction site on the Clyde to the Rosyth yard in Fife.
The largest hull section of HMS Queen Elizabeth was moved out of BAE's shipbuilding hall at Govan on Sunday.
It is being loaded onto a huge sea-going barge for a five-day, 600 mile journey to Rosyth, where the carrier sections will be assembled.
