Long Live the Confederation!
I'm assuming the CCG has pictures of the ships so we know the Bordrav and the Trak'hmar are both the same kindof escort destroyer (I didn't see this card in the pictures in the CIC WCCCG card scans), but the Frawquirg is just listed as an escort destroyer in FC. Can we really assume its the same type?
No, I suppose we can't - all we know is that the Frawqirg and the Wexarragh are the same class.
Of course, that brings up a more major issue - we can't prove that the Ajax is a Tallahasee-class cruiser, either.
Next version will reflect these changes.
How can we know the Invincible and the [/i]Hermes[/i] are Concordia class from a WC3 cutscene (a game in which the Concordia carrier hasn't even been thought of yet )? A pretty good case can be made that the Invincible is a Concordia because of its age, but that still can't pinpoint it to one class. The Hermes is contained in two or maybe three lines of text in the WC3N (the two that come to mind are the scouting in Loki and the one you have cited in the ship description. There might be one other) and I don't see how a class asignment can be brought about from that.
I think the logic here is that we know they're more important carriers than the Victory and that the Victory-type model is used to represent them in the cutscene.
