The AWACs fleet is too small...~30 a/c, and won't see the returns that the tanker fleet gets-not to mention any volume discount. The depot engineers have also told me it would require a wing mod to support the CFM.

Keep in mind the AWACS is based on a 707, not 720 (-135)

For now be happy there's (kinda) a new mission computing system coming on board and some fresh seats...hopefully a satellite will being doing AWACS job soon.
