A very entertaining read. A hard fought battle, but it seems the imperium is the winner this time.
It also seems, just as I thought before, that massed beam starfighters would be very effective. Costly yes, but then again using a ton of missiles is costly too, and they're not fast to be produced.
A couple of question.
I noticed you killed every single enemy ship. Did you consider that trying to capture any of them was impractical/too costly?
From your description, at least one of the raptors during the furies engagement seemed to be without working weapons, but maybe I got that wrong.
Also, are you going to shift productions towards morer beam fighters/warships?
