Plot hole: OK, a good laugh but why on earth deploy HMS Vengeance as a guard vessel to the G12 conference? Surfaced submarines are pretty exposed and useless against any likely threat, compared to a frigate or destroyer with SAMs, guns, small arms etc. And if the plot device is to have her launch a missile, Vengeance (as named and pictured) only carries torpedoes and Trident ballistic missiles, so hitting Volta's yacht with a missile wouldn't blow it up, more vaporise the whole area, even if it could attack something at such short range.
