since your joining a lawful based faction, no unlawful weapons for you obviously.
so, heres a good loadout (i use this on my merc bomber, and its highly effective imo)
4 x ARCHANGEL/EXCALIBUR/THOR HAMMER codenames.
1 x Nuclear mine dropper
1 x Supernova antimatter cannon
5 x 1 x Minirazor (my merc has an inferno, but since ure lawful, u cant use it. plus, a minirazor is just as good)
you could exchange two of the codenames for delibitators, if you prefer having some shield busters on your bomber. i personally dont need em, since my inferno is pretty handy at taking out shields ;)
missiles, steer clear of them. as well as nova torps. if you dont know how to use nova torps, i wont recommend u use em. if the turret is forward firing, get an adv delibitator turret, or dont bother, since u wont be bothering to looking at ure rear just to fire one turret:P
