Forward Gun
2-3 Liberty Cruiser Guns (they actually work better than you would think, VERY accurate)
2-3 Solaris Cruiser chainguns.
1-2 missiles turrets
Remaining make Order or Liberty Cruiser turrets.
EDIT: Mcneo, my Kusari Destroyer was VERY good at anti-fighter. I took on 2-3 fighters with it in 4.79, where fighters were hopelessly better. Got one fighter destroyed before I succumbed.
