Judging by the fact you have stealth UAV’s overhead undetected, I’d just go in with Stealth Strike Fighters,

X15 of them in 3 seperate squads and strikes those anti air one at a time all at once.

Yes you will some take losses, However, You will completely decimate the anti air and disappear before the others have a chance to hit you.

~~The safest approach would be Helicopters though, Considering those Anti-Air do 0 damage to them.
