Would a removable diplomatic module that could be replaced by weapons in wartime make sense?
Short answerNot really; it is more effective to make existing wardrooms, hangars, flex decks, galleys, and access routes adaptable for secure diplomatic use.
NotesDiplomatic capability does not need to displace weapons in a removable module. Wardrooms, hangars, flex decks, galleys, and circulation routes already required by the ship can be designed for multiple uses. A small amount of extra preparation space and careful access control lets a crew host visitors without exposing sensitive compartments or stationing guards every few metres. The result supports diplomacy while remaining useful to the ship's combat and aviation missions.
