The Corsair side turrets are 2xS3 each. The front guns are 4XS4 gimballed, or 4XS5 fixed. That is a ton of firepower. If the Corsair rotates at a decent speed, it is going to be most deadly with fixed guns. If it is pokey, it will be a little less deadly with 4XS4 gimballed, but with the new gimbal assist, it is going to be nasty as all get-out. Way more power than anything short of an HH, and the pilot of the HH doesn't get guns at all.
I haven't done a careful check, but I think the Corsair is probably ruling pilot-owned DPS. What does more? I can't think of anything.
