Ok, finally I finished with updating Klavs81's models, adding textures and splitting them onto pieces such as turrets, missiles, bridges etc. For now I have 4 ships ready: the Venture, Southampton, Jalkehi and Ralari.
I'm trying to keep the same classes for both sides. Unfortunately, Klavs81's pack doesn't contain any Kilrathi corvettes. So I decided to "upgrade" the heavy fighter Jalkehi into a corvette class. Anyway she has similar tasks and equipped with jump drive. What do you think, guys? Also the project has a new name: Spaceships Universe. :) Since it is not a strategic game, but online capital ship simulator, I thought the word "tactics" didn't fit here.
