A mission to destroy a high-performance mobile suit production factory works as a pretty solid premise, yeah. Taking out a part of the Zeon military effort with a small mobile suit squad on a assault carrier definitely sounds like it'd work. Given that the Federation right now is ... pushing back into North America right now, I think? Zeon would be distracted with trying to stall that.

So we're sent out on this mission, only to run into this unnamed Zeon corps who yeah, could have an ace that has a vendetta with the ship after Jaburo. And is thus leading the attempt to stop us.
