hmm, I could be completely wrong here. As I see it, it woudn't be hard to consider the fighters in Armada to be designed or modified to Spec Ops specifications; I mean, as I understand it, the Lexington CVN is built to be completely self sufficient and to require little in the way of escort or support (I suppose the same goes for the Snakier II) so that they can jump deep behind enemy lines and carry out the mission type that dominates Armada. Specifically, you are trying to destroy the enemy's homeworld. It seems plausible to me that some of those ships wouldn't appear in other areas of the WC universe; heck, even the idea of destroying a planet with those carriers seems to be confined to Armada, though the general idea of striking behind enemy lines is definitely a recurring theme elsewhere. (And of course, I was quite young then; how did you destroy the enemy's planet? Was it based on the idea that through the efforts of your carrier, you gave your side the advantage in the war and the end result is the destruction of the enemy's home world? I know how Kilrah is destroyed in WC3 and the novels...but I can't remember how Armada was explained...)
Just an attempt to better understand Armada on my part, I suppose. I encourage others to make corrections and help me gain a better understanding of this part of the WC timeline.
