88.2 m/s^2

For well under a second though, typically artillery muzzle velocity is, what, two to three thousand feet a second?

Still, it’s wild that guidance electronics and control mechanisms can survive that sort of acceleration.

According to https://en.wikipedia.org/wiki/M777_howitzer (typical howitzer):

- barrel length (x): 5.08 meters

- muzzle velocity (v): 827 m/s

Assuming a constant acceleration γ, x = γ * t² / 2 and v = γ * t

Hence:

- t = 2 * x / v = 12.29 ms

- γ = v / t = 67316 m / s² = 7000 G

A bit lower than 9000 G, but in the same ballpark.

Certain rounds, like Excalibur (https://en.wikipedia.org/wiki/M982_Excalibur) or BONUS (https://en.wikipedia.org/wiki/Bofors/Nexter_Bonus), are sophisticated and are able to cope with such accelerations.

That vacuum tubes(!) were part of that package, and were able to be that robust, still floors me every time I think about it.

> 88.2 m/s^2

Isn't that more like 9g?

Yes, thanks, I meant to write 88.2 kilometres / second squared.
