A small mod that unfortunately doesn't seem to have ever been completed. It has a few fairly nice custom models for some of the "r2" Taidan ships. The mod replaces the following ships:

Scout
Attack Bomber
Ion Cannon Frigate
Destoyer

The models for the scout and attack bomber are almost identical, as are the ion cannon frigate and destoyer. They are also un-textured. Of interest however is that the turrets fire in the right positions on the ships and the destoyer is particularly nice as it fires dual ions in a vertical formation, with a complement of missles and plasma bombs. It is unfortunate that the ships were never textured as on its own it could have been some fun.

Unfortunately I have lost record of where I have obtained this mod from and there seems to be very little information about it still on the web.
