Ok, I'm confused now. I thought there wasn't a Confederation-class. And what is The Murphy? That wouldn't be the 2nd Supercarrier after the Midway because it says in the manual that the 2nd one was going to be named "Sea"-something (I can't remember exactly and I don't have the books near me).
The Murphy-class are the Confed destroyers you see in Secret Ops. If you look closely, you'll see that their bridge design is very similar to that of the Midway.
There is a Confederation-class... it's the type of dreadnought the TCS Concordia from WC2 (CVS-65) is.
The second Midway-class heavy carrier is the TCS Mistral Sea.
Uh, explain what? I thought the original connection was between the Confederation class and the Concordia (and possibly Ranger) class.
I'm not really sure what you're trying to say, so I'll just re-explain the whole thing for the benefit of all.
The two Confed carriers in Wing Commander IV (Lexington and Princeton) are Concordia-class. This is stated in a movie segment in the Speradon series (Wilford orders you to capture 'a Concordia-class carrier').
The carrier in Wing Commander II (Concordia, CVS-65) is a Confederation-class dreadnought. This is stated in the Joan's 2664 update.
The Wing Commander IV novel heavily implies that the Lexington (Concordia class) is of the same class as the Concordia (Confederation class), claiming that they have the same deck layouts. The 'real' reason for this is that the author saw 'Concordia-class' in the script and assumed they were supposed to be the same type of ship (presumably the *script writer* also intended this...).
The explanation I made up was that perhaps the 'tower' thing (on the side of the Concordia, in the center of the Confederation) was a modular component and therefore possesed the same deck plans.
The Ranger class simply used the same 3D model as the Lexington and Princeton (scaled differently) -- it has no 'in-universe' connection.
