FYI : You can install Factory Drills on gravship.
It doesn't work in space (for the obvious) but having automated drills working 24/7 for such small crews wherever you land and when your crews are working on the field is great. Because free metals.
Mod : Vanilla Furniture Expanded - Factory Module
Don't mind the notification. I am just curious so that was unsaved.
So, yes, it can be installed on Gravship substructure.
