Apogee is objectively slow, aggressiveness isn't the only thing to consider - faster enemies can simply kite it.
speed isn't the issue. It'll literally be in the enemies face and rather shield is up, down or in even overloaded and it "might" shoot a single salvo. The tactical, missiles, etc take care of the little guys. When your fleet is in a firefight and a ship isn't firing it's most important weapon that it can fire all day, aggressiveness is very much an issue.
I was trying reckless officer on apogee once. Aggressive, but suicidal. It is your choice, tho'.
I'll give it a shoot. I have the command skill so if I can just get it shooting that'll be enough.
How curious, I don't have that problem on steady officers or officerless Apogees. Mine fire away continuously. I've placed the plasma cannon alone on the weapon group. Try that and see if that helps you.
it's in it's own group but I'll try resetting it manually, maybe put it on auto fire too. Think I had something similar happen with Ai in other games.
