I actually found out that Victory IS a concordia class Strike Carrier. Found it in the CiC ship database two nights ago while looking up the concordia herself. You have the Concordia Dreadnaught Class herselft and then you have the Concordia Strike Carrier Class ships that the Lex and Victory are a part of. You see, when you create a ship, in most navies, you do not create just a one of, but a series or class of ships. An example is the Nimitz class aircraft carriers of the USA, Nimitz, Stenis, Regan, Bush, Roosevelt, Linclon, and a couple others, 12 in all, but I can not name them all. In france during WWII the built the Strausbourg class battleships that were destroid by the british fleet. The Japanese had the Yamato class, in Wing Commander you had the Fralthi and the Snakier class cruiser and Carriers.
I just couldnt figure out why they had the Concordia and then called the Victory a Concordia class ship...I can not find anything in the background to find out why the strike carriers that carry the Concordia name would not have the phase transite cannon unless its because of the instability problems you all had referenced.
