Peter Hennessy visited Vigilant for the Today programme on BBC Radio 4 in 2007. He reported that there is a grey safe in the control room that has an inner safe that only the commanding officer and executive officer can open. In that safe is a letter from the current Prime Minister of the United Kingdom, the letter of last resort, which contains guidance and orders to be followed should the United Kingdom be attacked with nuclear weapons. This letter is identical to the other three letters in similar safes on the other three Vanguard-class submarines carrying the United Kingdom's nuclear deterrent.

In October 2017, it was revealed that the vessel's captain had been relieved of his command following allegations of an "inappropriate relationship" with a female crew member.[8] Along with the captain, his executive officer was also removed from his post amid allegations of an improper relationship with a different female crew member.[9] Later that month, it was reported that nine crew members had been dismissed for using cocaine.[10][11]
