One thing I forgot to add to practical discussions. When a bomber is fighting gunships or larger, with the average loadout they have the power to instakill the bomber. Not even talking a Mortar to the face here. A full salvo of Primaries or Defensives or whatever will instakill the bomber.
When we account for armour using Rudo's calculations, it becomes a much longer fight. If they happen to be lucky enough to have a cap 8, your SNAC's impacts leave the feeling that you're only doing pixelhealth damage. Using your maths, it'd be roughly 30 minutes for two bombers to down a Battleship, yes? I'm sure the Rocs would slip before then, and any competent fighter could make their life miserable even without the missiles I find most escorts spamming.
