High elevation firing leads to intense fire-support coordination conversations with the Air Force. While it’s probably classified, it would be interesting to hear how high that projectile flies in its trajectory.
Meh...big sky little bullet
I am sure I have read that the German “Paris Gun” of WWI entered what is considered space before descending.
I am no mathematician, but if one can gauge the angle of trajectory and distance, the apex should be discernable. What’s the formula. Google it, I reckon. Might even be a spreadsheet cheat.
...or we could ask Brian Williams.
If these are highly accurate, they will replace a lot of Air Force missions, because they will be much cheaper than sending an aircraft to bomb a target. Just clear the sky and use artillery.
In a combat situation, there are radio calls about artillery firings stating azimuth and max ord. I heard those for the 155mm and 8" but do not recall how high it was. Way over our puny helos, for sure. When some fly past you on the way up, it gets your attention.
Rule of thumb is 1,000 feet in elevation for every klick in range. Nothing classified. 40 miles = ~ 66 klicks = ~66,000 feet up.
Its mazing how cool the USAF gets with “Big sky, little Bullet” clearance of fires when the enemy rounds are impacting outside their own hooches.
One of the best comments I ever heard on this was when a flyboy was whining about clearance in Korea and the Artilleryman asked him if KJU would also clearing fires with them...
So it has the potential to accidentally be an anti-aircraft gun?
That's why the air picture and the indirect picture are combined into the ground picture in real-time so these things can be coordinated quickly.
Given the angle of the gun is approximately 45*, then you can estimate that the altitude would be approximately 20 miles just assuming a 45/45/90 triangle at it’s peak 1/2 way to the 40 mile target. That doesn’t take into account some of the parabolic arc and dynamic forces in play, but is just a very rough estimate.

You can make a pretty good guess with math.
