1.9 is the most recent release, isn't it? If that's the case, I've got a number of nitpicks (if these have come up before, forgive me, but I feel they need to be addressed).
Background. There's a sense of emptiness here that I didn't feel in the main campaign or any other campaign. If you need to, copy V's background from Clash of the Titans II, which also took place at the EP node.
The briefing also, IMHO, needs to be longer. I really don't find that a couple of lines is enough. Perhaps you could elaborate on the civilians that you have to ignore, or the Shivans around the star? Additionally, Stage 1 should cut to Stage 2 (ie use the fuzzy effect).
The debriefing seems to be lacking too. It also seems unnecessary, seeing as how there are no events telling the player to jump out in the event that the Julius is destroyed. You should add some of these, and then add a bit of a longer debrief in this case. Talk about some of the consequences, other than simply "thousands died". We can assume that, unless there was nobody on the ship. Give us some long-reaching or short-reaching consequences for its destruction, and definitely give the player recommendations on how they can do better.
The weapons loadout really needs work, though. Everything seems to be at its default number, which shows laziness on the part of the FREDer. Limit the weapons to how many fighters there are; have about enough of each cannon for one slot on each fighter, and maybe enough of each missile for at least one slot on each (for four fighters, I would recommend about ~480 Hornets, ~360 Tornadoes, ~120 Harpoon, ~90 Rockeyes, ~400 Tempests, etc.).
Additionally, just to show professionalism, I would recommend adding a "Destroy Malice Beams" directive in there as well. Additionally, fighters should be grouped into formation, as it looks a little more worked on then simply all over the place or in a large triangle.
Otherwise, it looks like you're becoming a much better FREDer, Cobra.
Was I supposed to nitpick this much? No one else seemed to be...
