HMS Vigilant (1996) SSBN  (12th)

This the twelfth vessel to carry the name Vigilant is the third of four Vanguard Class nuclear powered ballistic-missile armed submarines.

Built by Vickers Shipbuilders of Barrow-in-Furness, laid down 16-Feb-1991, launched 14-Oct-1995 and commissioned 02-Nov-1996.

Has two complete crews, the Port and Starboard crew, in order to spend the maximum amount of time at sea.

Basically she leaves port, vanishes and travels to her classified patrol area. On reaching station she relieves the previous patrol boat. Then in due course she is relieved by her successor, on which she returns to port, changes crew and prepares for her next patrol.

Little other fanfare accompanies the duties of a Ballistic Missile Submarine. 

Underwent a refit and refuelling from late 2008 to Nov-2010 costing 300m. Testing took until Mar-2012 when four months of sea trials began before her return to service.

In service Apr-2012.
