One of my jobs is taking care of several large wormhole minmatar towers. The primary threat here is a hac gang (no cap ships can come through). After lots of sisi testing, I settled on med autocannons with 0.035 rad/s tracking, 15km optimal + 63km falloff. Minmatar pos's have +50% bonus to optimal and falloff, so the guns should have 22.5km optimal + 94.5km falloff, even though this does not come up in 'Show Info'. ewar is mostly those use limited pg: several webs, scrams, ecm and one neut.
Domination med autocannons cost 10 times as much as regular ones (40 mil). Apart from lower powergrid usage (108GJ vs 121GJ), higher dmg mod (51x vs 43x) and higher ehp, there is dramatic difference in signature resolution (125m vs 400m). Therefore faction guns have the same sig res as cruiser guns, while regular have the sig res of battleship guns. Assuming the pos is attacked by a armor hac gang, ~100m sig radius orbiting at 500m/s, how much better would the faction guns be?
