here ya go, i'm done modeling the Destroyer and Battlecruiser. due to time constraints, i don't think i'll be able to do the battleship but i feel these two will provide a good starting point if someone were so inclined to keep them all looking similar.
these are in .dwg format, which transfers fairly easily into 3dsmax. they aren't textured hardpointed or any of that. all i have done is modeled it. i don't have the means nor skill to do the rest. so basically for these to be added into the game someone else is going to have to take over. if interested PM me and i can email you the file.
