It looks more like mockup to me. At the third picture, isnt it wooden sandwich?

Regarding the other ATA contenders I only have these two pictures ... the first from the FLUG Revue (issue ??) saying it shows a Boeing/Rockwell design and another one without any source !

PS ... + a wonderful build Model in 1/48 scale ....

There was not Grumman/Northrop consortium in AF/X program. I collected nearly all designs and they are here:

Hesham, you can take a look and probably there is the picture that you are reffering to.

Deino, thanks for the pictures. The first of them shows something similar that I have from forum member elider. The original drawing was lost, but he did a handmade drawing. But there are some differencies:

Bigger, more rounded nose similar to the aircraft Northrop aircraft used to
validate the B-2s stealth.

Side-by-side crew compartment and a different windscreen--similar to the A3 Navy aircraft or somewhat like a commercial airliner.

No bulge or sensor below the radome.

The long sensor housing on the lower body side is longer, thicker and
further back ( not as big as the E8 lower bulge but similar in shape)..

Intakes identical to Boeings TFX proposal.

Only one vertical tail and it had a shape like the B-29 (seriously).

Horizontal tails had B-29 contours as well, and did not have any downward
curve--they were flat.

Main wing was straight ( flat) for some distance from the main body, then
it turned downward at an ever increasing rate until the wingtips were
nearly pointing straight down.

Hello all
I don't know if this is the right place to ask: But I am searching for hi-res images of the A-12 avenger2 blueprints.
I know about the Habu-A12 site, but they are not exactly hi-res images...
Those are way too small..
I had contact with the museumowner(?) a few years ago, they have/had the blueprints of it. But they couldn't scan them, because of too much work involved and because of their size... I read in a thread here on this forum ( Yes, I did do a search for the A-12) that the museum is closed already...
Does someone know of another source for the blueprints?

cheers

I'm very sceptic about possibility to get them because many things were and stay classified of Flying Dorito. News that museum stuff ever had them is a breakthrough for me - you should have been using this rare chance if you still have his contacts.

Hey Gregory

Unfortunately, I lost the email-adress a few years ago...
Strange that a decent 3view didn't end up in some book..

Seems strange, yes, but so far it goes. All I've seen is a crap official 3-view. Koku-Fan had some nice cutaway drawings ca 1992 made from placards shown to magazine staff in FW.

More like the museum never got things completely together and never got built, let alone opened.  The last B-36 is now elsewhere and I've been told that the A-12 mockup is now in the "storage area" at the north end of the plant here in Fort Worth.  Most of the stories I've heard say that the exact 50/50 work sharing was a big mistake in that no one could make final decisions and lots of time and money got wasted on meetings to decide way too many things and too many things weren't coordinated until it was too late.
