FOAS did do the ship, and he never puts readmes' in them for some reason, don't know why?
I did the retexture work on the pod and depending on the ship probably the engines as well.
I don't know for sure but I think FOAS also did the one with the B engines.
As for the AWACs' version if you have max it should be fairily easy to do, just cut away the top pod and save the file. take one of his with the AWACs and remove everything but the AWACs dome and merge them, with a little moving then a weld job you should be done.
