Is this the same Wraith from the Armada 2 Babylon 5 mod?
You can find a whole bunch of the B5 races (if you just want ship sets and not the whole thing) on the following page:
B5 Mod Homepage (WIP)
Go to the downloads section and under the Graphic File Names, you can get all the races in one shot (Centauri, Minbari, Narn, Earth Alliance, Shadow, Vorlon, League of Non-Aligned Worlds, Hyach & ShogToth/Soulhunters). The Netral Races include only a small assortment of ships (Gaim, Llort, Hurr, Grome & Yolu). Still working on breaking down the LoNAW into their component races.
