This photo is the YF-12A and the chine mod is for the ASG-18 fire
control radar. to insure directional stability for the chine being
cut three small fins were added to the rear of the underside of the
YF-12A

So, I did get it right. I guess they tried a number of different
chines/nose cone profiles before they settled on what is the more
familiar one from the SR-71.

Neat.

Yep but there were only 3 YF-12A built and two crashed, the one
left is at Dayton. there were others in the production, but the
airframes were changed to the SR-71, can't recall how many off hand.

there were several nose mods tried, and the "dented" one was the last
& it was for the ECM antenna.
(from what I remember , NASA had a canard on atleast one test..)
have to go to the books to get the model/test...)
there were also several noses depending on the mission.
much like the Dragon lady has....
again got to go to the books, and can,t right now. got to
finish mowing the front yard.. .
