I might then be able to imply that the later models were the ones that
need this feature.

Is that on the right track?


Photos of the Blackbird as early as 1979 & 1980 show the ECM dents

Interesting thread. The Blackbird that displayed at Abbotsford in
1986 appears not to have had them.

Hey! I resemble that remark! I was at Abbotsford in 1986 and got this shot
of the SR-71 on the ground. I also don't remember seeing any indentations on
the nose. The chines were smooth and uniform all the way around the
aircraft.

Here are two of my shots....

ENJOY!
