Current ship lineup for a universe I am working on. Sizes are aproximately to scale. The cruiser is about 1.5 km in length. All three are still works in progress.
If I ever end up finishing this project, there will be an epic battle between the empire and the union. I'm trying to create a style of capital ship combat that has yet to be seen in movies or games.
I'm interested to know what differentiation you are attempting to go for with capital ship engagement. I really do love "big ship" battles. The bigger the better!
What's the universe you're working on for? Are you planning in-game usage of your ships? It shouldn't be that hard to import all these ships in FreeSpace 2 SCP.
as far as what HASN"T been done yet, that's tough. The basic style of space combat movement, in many differant styles, akin to naval engagements or aerial dogfighting. The most you can do is either A, invent a new weapon type that revolutionizes warefare, or B, invent a new environment to fight in (say, fighting in a asteroid field or upper atmosphere of a planet would be differant than normal space fighting), or C, invent a group-specific style (does it favor defensive maneuvering, offensive maneuvering, ramming, etc.)
What program did you use to model them?
