I know that right now, the Protector Starship is still in an "unfinished" state, but apparently the AI has access to them.
Holy crap, these things have crazy amounts of health, huge range, massive damage, can intercept missiles, and most importantly, can fire through forcefields...
Which means that as a piece of any major AI attack, are unbelievably deadly, and can kill your Home Command Station within seconds.
I am hoping that the ability to fire through forcefields, in additions to all these other ridiculous things, was just some kind of balance oversight. In its current state, it completely mitigates any need to ever use the Zenith Devastator, which is inferior in just about every way.
Hopefully the final iteration of the Protector Starship has relatively weak guns...and can't fire through forcefields.
