I think you have too many Global Hawks, the US only has 48.
You AF also seems to be lacking some ground support, how about a few gunships (AC-130esque vice helos)? Also, tankers?
I had a feeling I had too many Global Hawks. I was using the actual amount that the Australian Federal Government has planned to acquire from the US DoD. I used the Airbus A400 in lieu of the Hercules and the Airbus A330 MRTT fills the tanker role. I was also thinking about including some Warthogs into the equation. I really wanted to have the Sukhoi Su-30 Multi-Role Fighter in the lead fighter role but I gathered I would cop a lot of criticism for my choice.
