The 7,400 tonne attack submarine left the site in Barrow-in-Furness on Saturday 15 September for Her Majesty’s Naval Base (HMNB) Clyde, Faslane, which will become its operational base. This major milestone in the submarine programme is the point at which Ambush will begin to test its range of capabilities, under the control of Ambush Commanding Officer, Commander Peter Green and his crew.

Over the next year she will be put through her paces in a rigorous testing programme and regime of inspections, certification and assessment to prove she is ready for operational deployment. Once commissioned into the Royal Navy she will become known as HMS Ambush and fly the white ensign for the first time as a fully commissioned warship.
