OK, so that first post isn;t particularly informative. But it's late. So sue me.
This is a proof of concept for a dockable deimos fighterbay. I emphasize proof of concept, because it's very obviously a dodgy model, dodgy texture (tga at that with no normals or shine map). If there's call for it, I'll improve the overall model and textures. Otherwise, I'll wait for the new HTL deimos and see how that goes. In either case, it might be useful for FREDders for the moment, although I will again emphasize this is a proof of concept and has barely been tested.
So, how to use it. Dock it to your deimos using either dock, just make sure left docks to left or right docks to right. Destroy turrets 1 and 2 on the deimos, they're under the fighterbay. You might want to use some clever FREDding to ensure that both the deimos and the fighterbay stay at the same hitpoints (I would suggest a repeating event that constantly gives both the min of their two hull percentages), and you may want to make the bay stealthy. Up to you.
Oh, and my table may not work outside of my modkit. If so, it's because I've used the "Modular" flag. Change that to cruiser or something and it should be fine.
