This is post Raider Squad but if you are looking for anti-Turret....
4 Tempest Squadrons+Cluster Missiles and Accuracy Corrector 16 guaranteed hit results (not counting those few rolls where you get 3 natural hits/crits and don't need it) That is a Decimator in a single turn (and maybe a Falcon) and at that point you still get 8 hits per turn to mop up your opponent's other ships
But not every turn!
