Welcome to HMS Vigilant's Web Site. The site will be regularly updated in order to allow families, friends and anybody with an interest in the boat to keep in touch with what she's been up to.

HMS Vigilant is the third of the Royal Navy's Vanguard Class SSBNs, and as such she is part of the United Kingdom's strategic nuclear deterrent. Capable of circumnavigating the globe without surfacing she is not only a warship of terrifying firepower but also home and workplace to her 146 man crew.
