Watch: Royal Navy frigate floated under Erskine Bridge

A Royal Navy frigate has made its first journey down the River Clyde carried by a giant barge.

HMS Cardiff is the second of eight anti-submarine warfare ships being constructed at the BAE Systems Govan shipyard in Glasgow.

The barge will carry the ship to a deep water site in the west of Scotland where it will be gently lowered into the water for the first time.

The £1.2bn warship will then be towed back upriver to BAE's Scotstoun site where "fitting out" work will continue to prepare the ship for delivery.
