Is it possible to make a civillian station on a jump point in a stable orbit and then just put military vessels (Like fighters, facs and corvettes) in its hangar bay? It seems like a win-win to me. There is no deployment, you would be able to make it massive, the costs are low and you can have a big ass defence fleet orbiting it because of the orbital habitats, so no need to worry about deployment time.
Not possible, I'm afraid. Hangar bays make a ship military. There are commercial hangar bays which don't, but they don't make the maintenance timer stop for the vessels inside it.
this is possible if you put maintenance modules on the station as well, as they maintain the vessels within the hangar as well.
heres an example station i use.
