Thanks! Software design and development are things I'm fairly good at, so if I fail at this, it at least shouldn't be because of inadequate planning. ;)
Death Star -> Shooty Moon.
Star Destroyer -> Moon Obliterator.
The idea is you're on the Empire's side, blowing up the last of the Rebels in the Death Star. The Star Destroyers don't really matter much unless you can actually turn rebel yourself, since the Death Star can take out the planets by itself and gets destroyed immediately if the rebel fleet catches it anyway. So yes, the idea is that if it gets that far along, you can turn on the Empire and take out your own fleet.
