I made a thing to help compare the Hwasong-10 and Hwasong-12 missiles. A lot of people are rushing out their analysis. We’d like to get it right before publishing. I am old fashioned like that.
I _think_ you meant that “I made a graphical slider widget to compare the images of Hw-10 vs Hw-12 missiles photographed on the same day at the same spot on the parade route. Drag the slider left and right to see Hw-10 and Hw-12 images respectively.”
(Of course you already know that someone like your very own Melissa Hanham can well measure pixel dimensions on the image and compare them to the mean height (5’6″ ?) of the perspective foreshortened parade observers on the sidelines to estimate within maybe 6 inches the length and diameter of the missiles. From this fuel and oxidizer tank volumes can be estimated assuming stochiometric fuel/oxidizer ratios. Specific impulse and engine thrust is probably just a good guess, as is the overall missile empty weight with fairings and warhead. Maybe you are trying to open source the analysis here?)
Are we ‘certain’ that the mockups paraded are representative of the item that flew? I believe the garage photo is what flew; it looks considerably skinnier to the eye.
Are Those Barrage Balloons?
Old-timers used to see mobile missiles like these in the Russian parades, twice a year. Seldom were any seen deployed in the field.
Quality is not old fashioned.
Jeffrey,

I meant “crowd source”, not “open source”.
Yeah. It’s NTO/UDMH going by the weld lines on the missile body.

We aren’t, but it looks very similar. More measurements may be needed.
