Advanced Tactical Aircraft – ATA

I want to discuss the ATA project, which led to the later cancelled A-12 “Avenger II” …. does anyone knows anything about the concurring projects and their designations ??

All I found (in an older FLUG Revue issue) was this painting which should depict a design completely different to the A-12 …. is this a fake ar was it actually a real project (maybe A-11, A-13 ???) ???
