The Explorer is one Mackie still wants me to do, but it is on the hold list. Once I get back to that ship then most of those are done as well, he used a Combination of the Explorer, and Excalibur to do that ship.
The Hickman is done I don't plan on going back to it at this time. The FCA, FCL, etc are all pretty much the same texture with different names. Since they are basically the same they will work on other ships using that style of engine, so they should be pretty much swapable already.
So still 2 two more Federation ships to go then they are done.
