Tier Unit Upkeep Costs

[FoxURA]

I have been playing Final Frontier a lot lately and have just noticed something that I think was poorly done. Anyways, I was working on building up my economic base to support a bigger military when I noticed that my upkeep cost seemed unusually high. After checking around I figured out the reason for this which is that the Space Station spawned Anti-Ship Missiles cost money. Personally I don't think that weapons that don't do anything but sit in silos and only require occasional inspections should cost any upkeep. Anyways, military unit in Final Frontier seem to have up keep costs that are too high. Personally I think there should be a tier-based upkeep system where as the technology level of an empire, would be considered less advanced and therefore have lower upkeep costs. Also, I an empire places emphasis on a certain unit or type of unit and has a large number of them, it would make sense that because parts would be more common and easier to obtain, the units would have lower upkeep costs.
