SecDef Robert McNamara ordered all the SR-71 manufacturing tools
destroyed so he would have more tax dollars to waste on the F-111. In
1994 William Jefferson Clinton used line item veto to cancel all
funding for SR-71s. They are now in museums. The pilots said that we
really need that airplane today for reconnaissance over places like
Iran, Iraq, Syria, Korea:country-region, China, Russia, etc. If it
were not for Clinton, SR-71 would still be performing that
reconnaissance today.



Does he know that Kingfish isn't?

Interesting, I always thought the SR was short for strategic reconnaissance.

It was first deactivated in the '80s, before the Clinton administration.

"Deactivated" is not the same as "retired".


Interesting point.

PS: IIRC


Ha! That should be my sig file, or standing caveat.

What he is hinting at is probably the Aurora. You know, the one that
leaves donut shaped con trails?


That's no longer with us, is it?

Anybody ever hear about Pumpkinseed? I -think- that was the external
combustion (for lack of better term) project.

Well according to THE GOVERNMENT it never was. And the plane that
didn't/doesn't exist was supposed to be pulse jet.

Not quite. Though the principle is essentially the same, the engine has not
moving valve at the front. A pulse jet wouldn't be able for supersonic, let
alone hypersonic flight.
the inlet would have an annular inlet arranged so the flow would direct
each pulse down the rear of the engine, but there would be a small efflux
out of the annular inlet. The biggest advantage to this system is that it's
easily throttleable simply by varying the frequency of the pulses.
this thing almost certainly exists. More than likely it's a development of
the Convair Kingfish which was , like the A-12, an upshot of project GUSTO,
but we're not going to be told anytime soon! I read about the Kingfish
years ago and can't find anything decent about it on the net, but it was a
parasite aircraft with some sort of ramjet or zip engine that had a ceramic
coating and was capable of cruising at over mach 4. At least one of it's
designers has alluded to it actually having gone ahead, but it's still a
very black item.

I mis-wrote. I should have written Pulse Detonation Engine

Hmm, amybe I'll try welding one up out of some old drainpipe I have
outside!
I'll never forget the sound of the old dynajets some of the guys had at my
CL field when I was a kid.

I think it's pretty likely that Kingfish (or Aurora or whatever they
actually called it) is flying. If I had to guess, I would say they
retired the SR-71 because it was old technology and because it was
vulnerable to newer generation anti-aircraft missiles. As far as the
secrecy surrounding the new aircraft, it is hard to see what would be
gained by making it public.

Also hard to see what could be gained by keeping it secret at this
stage. If one exists, any opposition knows about it. It's been in the UK
and you know how crap they are at keeping secrets. (One of them had a
close encounter with a Brittania airlines 767 in Manchester about ten
yars ago, though it could have been an F-117, of course)
in this day and age when sattelites can read licence plates and everyone
knows it you'd wonder why they would bother keeping it secret after all
these years for any reason other than habit.
