I think next turn I'll build a Carrier (or two) with as many Fighters as I can and take out PeterKaan. Might mix in a few other ships depending on my resources. That'll give me another planet to build ships from and then I'll move in on carlwolcott.
That was exactly the strategy I was contemplating for Kip. Except I was going to toss in a few frigates or cruisers as "damage shields" so I don't lose my carrier.
How many fighters does a carrier hold?
