The Imperial Navy makes extensive use of orbital platforms, space stations, and other such facilities. The largest of these are capable of holding off small fleets of enemy vessels unsupported while still able to resupply & repair all but the most crippled ships of the line.
Bottom left flat because honestly, this will take enough time to print before adding in the parts nobody sees. Comes with a 3.5mm hole to fit standard flight stands.

Perfect for games of Battlefleet Gothic and other space games. The Basilica piece could probably work as terrain or an objective marker in games of Epic40k.
