Do the UEF even need an AWACs ship?
Yeah, AWACSes are useful outside nebulae.
(AWACS stands for Advanced Warning And Control Systems 
)
I know what 'AWACS' stands for.
You spelled the plural of AWACS wrong.
(then again I did too probably
)
I was just wondering why the UEF would need them for, considering they had no outside threats, there are no nebulas in Sol, and etc.
As I said, AWACS
are useful outside nebulae. They can be used to locate individual ships within Sol (remember how in Epsilon Pegasi they were unable to locate the Repulse? AWACS might be useful here.) and for other general electronics purposes (like the Hammako jamming comms).
And they did have outside threats, if you read the prose section you should recall some fringe movements in the Kupier belt.
