The Royal Navy's £1.6bn submarine 'Ambush' arrived at her base on the River Clyde for the first time this morning.
The 7,400 tonne vessel was built by BAE Systems, and is the second of the 'Astute' class nuclear-powered submarines.
She will continue sea testing in the coming months, and will formally become 'HMS Ambush' when commissioned into the Royal Navy.
She will be armed with both Tomahawk land attack missiles and Spearfish torpedoes.
