Ok, so I went to work and 8h later I am back with a good thought about this.

First, seeing how we would be all allies I think we can go with RP and forget about the number and a 'System' in general.

Second, I have reserves about this in the fact that: Who would we fight? Or what, seeing as how the US is, lets say it honestly, is next to invincible. The Russian navy is horribly outdated while the Chinese is simply too small to compete. I'm not even American but I can only say that the US navy alone could easily face all others together since in this age of nuclear warfare, it is the only country that bothers with ships for power projection, even mighty britain forgot about the fleets because one could be anihilated with a single nuke during the cold war.

We can bend reality, add aliens, I just want to see your answer to this problem. CS is: In progress.
