Strategic Costs

How much does it cost per month to maintain a strategic base or strategic airport. I'm thinking about getting one.

needed personel*salaries + needed maintenance*unitcost

I know that, but how do I find all that out.

I don't wanna waste 3 months profit only to end up with a useless airport.

Idk how much personnel it needs, or its maintenance.

I can sell you a base, it'll be done in 5 months.

I think that it costs as much as 20 forts to maintain.

Hold off until you have about 30.0M civvies.
