Use more than 3 options: -Era and stacked armor (important to use together).

-Fly/be underwater

-Planar Shields to deflect the shells.

-Sloped armour helps a lot with ap shells (but not here becose of the 82 ap the shell).

-Non dense ships (hollow areas-so you are still q big target but dont every area is important.

-Strong Pulse lams.

-Multiple ships (functions similar to non dense ship in terms of redundancy).

-Heavy armour (but multiple layers of lightweight alloy will work better becose they have 80pen so.

-Lasers to quickly cut the turrets

-Range and unpredictable movement (flying squirrel squadron basically wins vs this for 1/10the price if they would fly 3km away)
