Could a surviving G3 or N3 have become a Royal Marines helicopter assault ship?
Short answerPossibly, by replacing the third turret with a hangar and using the deck around the funnel for helicopter operations.
NotesRemoving the third turret of a surviving G3 or N3 could free space for a helicopter hangar. A flight deck could extend aft around the funnel, with takeoff and landing areas beside it. Such a conversion could support Royal Marines helicopter assaults while retaining heavy guns forward. Its feasibility remains tentative in this hypothetical proposal.
