Right. I was gonna say...
Are you strictly talking about the crew required to operate the ship itself, keep it functioning? Or are you also including crew needed to have the ship fulfill missions and operate as a starship?
All the security and medical and tactical and ordnance and science personnel can be dropped right off, they're not needed to operate the vessel. Correct?
This was my thought, all though do you need the tactical department for offence/defence? shields and weapons?
Couple of my own thoughts:
What would the minimum/skeleton crew be for an operational vessel?
For the sake of this question, lets say thay 800 crew is the standard for an operational Galaxy-class ship - How many crew are assigned to each department?
Command, engineering, flight control, medical etc...
