I think I had some glitchy dependencies. Reuploaded, should be fixed now.

Every time I deploy missiles, the launch grey; I think they are lacking fuel, or some other bug is at work...

@Morrigi
That was mainly for cost/weight issues. Usually I've launched all of my missiles before enemy ordnance arrives, so it's rarely an issue.
That said, swapping em out for similar ones with a few cm of amorphous carbon should do it.

Firepower's decent, but you really need to armor your magazines. They explode at the drop of a hat when you start throwing nukes around, which promptly cuts the ship in two.
