Make all efforts to take out the AWACs, 3 isn't a big enough number to have one in the air constantly, so destroying even one will put a big hole in the enemies capabilities.
I'm thinking it's more useful to use the strikers in a suicidal mission
Crashing their sukhoi and migs in f15 shelters , they can trade one for one aircraft
If we are allowed to start the war with a suicide mission, what about using a regional airliner like a Fokker F27 Friendship?
Buy it covertly from a third nation charter airline and don't repaint it, fly it at night to one of your more discrete hangars....
Fit it with a smoke canister in one engine and some air to ground weapons.... (cheap easy to fit 20mm pods...., Anti runway cluster bombs in wheel wells..., rockets pods and maybe guns through side doors....? Not sure how easy it would be to disguise the pods but maybe fit them as extra fuel tanks as a fighter pilot isn't going to shoot at an airliner with extra fuel he doesn't know the exact type that well......)
Fly to the main base via a route that makes it look like a third nation charter flight.....
PAN, PAN, PAN....... we have an engine fire we need to divert to this nice long runway....(just happens to be your main AWAC base)
Start the war by taking out the large AWACS and Tankers that cant fit in most shelters anyway and probably a few F15s just sitting outside in peacetime.....
This would almost certainly be a suicide mission, especially if they sent up an F15/F5 to escort you (how likley is that depending on alert state pre 911?) in but you would probably get at least one pass over in peacetime.... (maybe fit a rearward firing sidewinder/20mm gun to trick the F15 to come in and look at the landing gear or smoke coming out of the engine)
That or just land and then release a group of commandos to attack the base 40 guys attacking with surprise might do a lot if the air force guards are just a few bored conscripts at 11pm?
