I think that having an official designation for purposes of fluff might be nice, but for purposes of usability in-game I’d like them to be either be callsigns for the expected pilots, potentially with a prefix for the type of vessel (SH-Nhaima for a shuttle, FTR-Nhaima for fighter, BMR-Nhaima for bomber) or reference it based on the ship it was launched from (Raven-SH-1, Raven-SH-2, Raven-FTR-1).
Even if we don’t move towards storing strike craft (fighters, bombers, etc.) on the ships immediately, I think we should pick a naming scheme that allows for the possibility for us to change it in the future or even just for more free-for-all configurations in sims.
