Space Stations

They are space station ... they do NOT move. You must build them where you want them.

Build a ship with a shipyard on it, move to where you want the space station, and then have the space yard build it.

Remember that the space station needs supplies and/or ordinance to function. On ships; supplies are stored in the engines, your space station will have 0 engines so you will need at least 1 supply storage.

all bases do not move FYI. Thats why they are so big (though not, in my opionion big enough)

There should be an option for using tractor beams to move "fixed" objects... even if you can only move it 1 hex per turn...
The only space station that can move is the baseship...

I don't use bases much, they are too vulnerable. Though, I did design one in my last PBW full of nothing but repair bays to greatly increase my repair rate.
