I don't think that payload/third stage is bigger than the Nike. I think there are strakes below the delta fins that make it look fatter. I think it's the same size as the Nike.

What about a test using the S19 guidance system for the Black Brandt? Developed in the mid 70's and apparently used a lot at White Sands. From what i can find, it was/is 17.26" OD.


Charles,

That is an interesting hypothesis . . . It does look like a Black Brant S19 unit.

I'd sign off on an S19 test. That'd explain the pitot tube nose. The little fin section could very well be .75 inches larger than the Nike; it would be really hard to detect at this range in a picture. And the fitting between the fins could be a camera.

That would be a heck of a test to see if the little fins could bring the mass of an HJ-Nike stack to a more vertical line.
