And I don't think it a secret that most people do not think that plane will ever be completed. My comment about a secret project was referring to a hypothetical aircraft that is in operation but isn't publicly known.

Yes, it remains to be seen if the SR-72 will ever become a reality. As an engineer I believe it is possible to make such an aircraft a reality, but I have no knowledge of the program beyond what was stated in its announcement. As for the possibility of an already extant replacement, anyone who revealed information on such an aircraft without authorization would be risking their freedom (and possibly their life).
