English: HMS Vanguard "vents off" as she leaves HMNB Clyde in Scotland.
HMS Vanguard was the first of the four submarines of her class to be launched, on 4 March 1992 at Barrow. As the name-ship of the class she continued to lead the way, carrying out the first Trident missile test firing in May 1994 and the first operational deterrent patrol in early 1995.
She was also the first to undergo her major mid-life refit, from 2002 to 2004, during which she was fitted with the new Core H reactor core, which will provide the power to see her through the rest of her service life.
