Bottom projectile is traveling at a normal speed, just fired last.

Then the distance must be almost zero, as it exhibits no drop over that range.

That might have something to do with this being a chart for powered missiles.

However, the comment was talking about arrows...

I’m over here with some popcorn as nerds debate the project motion of a hypersonic missile named “arrow” and shit.

Go with a fantasy arrow made of light, for the last one.

The diagram is about normal unpowered shells. They use different amounts of propellant to achieve different projectile speeds

Y'know, I think you're right. That gray bit looks like the tank barrel. I mistook that as part of the projectile path, and I misinterpreted the overall design as a missile battery.

If you want to know more, look up Multiple Round Simultaneous Impact

Are we looking at the same image? DO I NEED TO GET A RULER?

[–] FishFace@piefed.social 1 points 2 months ago (1 children)

That is not how this concept, time on target, works

[–] Tja@programming.dev 1 points 2 months ago (1 children)

It works by firing at mach 5?

[–] FishFace@piefed.social 2 points 2 months ago

It's easier to just refer to "multiple round simultaneous impact" than to try to explain succinctly, especially since I already got the term kinda wrong (time on target is more of an umbrella category/earlier version)
