I would beg to differ on the "fins" of the 117. They were rudders is all accounts. Rigged , removed, and reinstalled those for a good many years and never were they ever referred to as fins; by Lockheed, tech manuals, or those that lived with them. They were rudders only and only provided yaw control. At least that is what we rigged them and operationaly checked them for. All roll control came from the (4) elevons. Either way, that new bird does look pretty awesome!

I would also agree totally with the comment on the RCS, unless they have figured out a way to change the laws of physics.
