You put forward an interesting argument tim, and I disagree with it in only one particular area, namely yes, the SR-71 is an early example of stealthy
design, but it is not stealthy while supersonic, indeed the very reason that the F-117 is subsonic was because the technology did not exist to make a
supersonic aircraft that was stealthy, that was one of the primary design goals of the ATF programme because it was known that this handicap needed to
be overcome for LO to play any meaningful part in the F-15's replacement.
Having said that I take your point that this F-19 design might be a basis for a spyplane rather than a fighter, which would bring me back to the point
in my earlier post that the plane would necessarily be a lot less stealthy than anyone supposes, especially if it were to be particularly fast.
Regarding timescale I am supposing (for supposition is all I have) that the F-19 was begun after the F-18 but before the F-20. I understand that
apologists might try to make a case for this not being so but there is no logical reason to accept that an 'F-19' would be started after the F-20
and F-21 designations had been allocated to other types, therefore, if we are making a case for there really being an F-19, it would have to have been
started between 1977 and 1981.
The timescale could have been later if the 'F-19' designator is completely wrong (maybe F-119 as I suggested?)but my thoughts at this point are that
the design is not real because the technology did not exist at that time, or there would have been no reason to deploy the F-117 in service, also,
whether it was a spyplane or not, the failings of the design as a practical flying machine, as I highlighted earlier, still stand. I would like
someone to address those for me as I am no aviation professional and accept that my amateur assesment could be wrong.
This does not mean I don't believe there is a secret spyplane (I am sure there is, in fact) only that I am sure, unless someone can show me where my
assumptions about the design are wrong, that this is not it.
