Is Star Trek the Royal Navy in space?
Short answerThe preferred comparison is an idealised US Navy, with Andromeda's Commonwealth closer to the Royal Navy in its behaviour.
NotesScience fiction can reveal the assumptions of the period in which it is written. When an audience member suggests that Star Trek is the Royal Navy in space, the preferred comparison is instead an idealised United States Navy. Andromeda's Commonwealth is offered as the closer Royal Navy parallel because of the way it behaves. These are interpretations of institutional character.
