Not me, friend, and once he got to explaining how to account for air resistance i just kinda dozed off cuz im stupid so take it with grain of salt.
your friend is a freking wizard
Howitzers can generally adjust the muzzle velocity of the shells, by adjusting the amount of propellant bags used.
In theory it should be possible to target a scouted vehicle with a howitzer, particular light targets.
There are just a few problems:
- HE shells in WT have much weaker fragmentation than in RL
- We can not change the propellant/velocity of a any shell fired
There’s a guy on YT using the 100mm HE from the BMP-3 together with scout drones for indirect fire.
So it should be possible to hit targets on WT maps when firing HE rounds at 250m/s or less.
+1 however with more changes.
I agree with the comment above by @KillaKiwi
But also more changes:
- Make switching through charges possible.
- Dont gate keep it to scout drones, but also Squat members, other Team Planes and possibly more for intel.
- I forgot Nr.3
For anyone wondering, here is the firing simulation for most of the artillery pieces in the game :
The simulation is done to obtain the distance for a non-direct shot at maximum gun elevation (minimum distance obtainable for a non-direct shot). This simulation may be slightly imprecise, I do not take into account either the Magnus effect or the Coriolis effect (variation of the order of tens of meters for the first and of meters for the second)

Given the distances obtained, I think I can say that indirect fire for artillery is impossible to add to the game (unless the maps suddenly become 5 times larger)
It’s rather difficult to get direct fire. Mind you indirect support isn’t entirely accurate and those who can pull it off are often skilled at it.
Besides, people dy do Indirect Fire Support in-game via the drone but it’s still difficult to properly calculate and hit your target. Or the area around the target. So generally no, it didn’t become WOT since the suggestion wasn’t asking for a WOT esk system.
Anyway to summarize, its still high skill to pull it off.
Yea, friend arrived at similiar conclusions once he started working with the correct projectile weights.
But velocity could be lowered, depending on the number of charges.
I was just about to sit down and do that math, THX for saving me the trubbel!! XD
Isn’t that a feature only modern vehicles have or am i misremembering?
The problem is that the velocity should be divided by 4 or 5 to allow really effective bell shots (the maximum speed to not go more than 1km in indirect fire of shells of this mass is less than 200 m/s and I don’t know if there are charges allowing it)
Theoretically, charge adjustment is feasible for almost all artillery. However, modern artillery has a computer that can calculate and propose the right combination. I don’t know if it’s feasible in the game and especially, for modern cannons, I don’t know if there are charges small enough to reduce the speed enough (in general, charges are added to increase the range, it is rare to remove them)
No, that was the case for almost all artillery systems in use.
There’s tons of data for German WW2 howitzer and the muzzle velocity for each amount of propellant charges used.
In general it was practice to fire at the highest elevation using the lowest muzzle velocity for the range, since the slower the shell impacts, the greater the fragment distribution, since the faster the shell goes, the more fragments will just be directed into the ground instead of the sides.
huh, i didn’t know that.
well yes, static or towed artillery i knew used charges VERY early on. Even a lot of 120mm mortar systems use a similar system.
But for the game it would be exclusively self propelled artillery, so was the same “charge” systems in use on most of those older/semi old self propelled artillery as well?
I think i have seen images of Russian made self propelled artillery using ready made casings as propellant, but those might also be adjustable somehow IDK. I would love to learn more :)
makes perfect sense. :)
To be clear the title is something I adjusted as the initial title for the suggestion wasnt as to what was being suggested, as well to better align with our rules/guidelines.
While fair, and thank you for keeping the forums clear, the point with minimal range still stands.
Yeah of course.
Propellant doesnt grow on trees (well kind of does).
Appart from the rule that the goal was to be reached with the smallest charge needed, to save on propellant, lower velocitys and steeper angle of inpact (top down) is ideal for the shrapnell.
For example the 15 cm s.I.G.33 has 6 charges, which are added on depending on the needed amount.
Same with the 7,5 cm Le.I.G.18 L/12, which has 5 charges with velocitys from 95m/s to 221m/s.
Ammo/Propellant Sheet
Cool!
Thanks for the info :)
lol whut? XD
that’s like, what, a maximum 700m shot? XD
I mean, during those times that might have been useful, but damn.
So basically the charges were put into a casing, the casing was then loaded with the shell and fired? (my german is horrendous at best) or were there different casings with different amount of charges premade?
Its the Light infantry gun, for very close action.
They come as full charge in the casing, and all but the needed ones are taken out befor fireing.
