I use a modular approach - chances are if you are putting a station that big in deep space, say near a JP then you can probably afford to do what I do:
Create a space station design that's just a maintenance module - build them with factories and then tug them over one by one to where you want them. Do this until you are happy with the amount of military tonnage it can maintain
Create another design thats just a rec facility and also tug it there
At this point you've basically got a military checkpoint going, the station will be maintained and you don't have to waste space with long deployments due to the rec facility thats in the same fleet - this has the added bonus of being able to station actually mobile military ships for indefinite periods of time so you don't have to rotate patrols in and out.
Optional add ons would be a fuel depot as a fuel hub that can be a deep space fuel stop, maintenance storage (to reduce micro, just fill it with many years worth of MSP and your gucci for a while), if you want it to act as a reload point you can also get a large ammo depot as an ordnance hub going (use commercial magazines on it though).
This allows you to tow military stations and such back and forth to points of interest that you want to defend in deep space without too much micro trying to remember what needs to be supplied.
It does however require some sort of supply ship for MSP at the minimum and with the extra modules you could be dealing with colliers and tankers/harvesters too.
I now notice that a bunch of similar replies have been posted, screw it
