So you want the belting of German ammo?

Ok. Here we go.

Translation from part of:

Luftwaffe ammunition instructions for onboard weapons L.Dv. 4000/10,
Part 10, Handbook of the ammunition for aircraft shooting weapons, June 1942

Notes of me in cursiv

(1) 2 cm weapons MG FFM, MG 151/20, MG 151/20 El

MG FF = Flügelfest = wing stable, that means that the weapon can be operated under high g-forces, which are possible in the wings during combat. Of course later models can do that, too, but in the mid 30’s this seemed not too normal, remember the problems the Brits had with cannon during BoB.

FFM or often FF/M: with lighter parts, to be able to fire the thin-jackened M-round.
Bf 109 E-2 MG FF, only motor cannon, not build, Bf 109 E-3 MG FF wings, from E-4 MG FF/M. MG FF motor cannon in one He 112 during Spanish civil war, but only use for airground attacks.


MG 151 El / 151/20 El = electric fusing of the primer for the propellant. More exact timing than the mechanical pin fusing. Used by FW 190 root wings to give firing through propeller a plus safe. When getting this cannons in the wing later, also the El model was used to prevent interchanging of the ammo.

MG 131, MK 103 and MK 108 were electric fused, too. As they had only electric fusing, the El is not in the name. This changes when designating the ammo.

a) Fighters

2 x M with self destruct fuse approx after 1200 m
2 x HEI-T w sd ²
1 x APHE wo sd
or
1 x API phosphorus wo sd ³

Footnotes:

²)The API will be replaced in future with the more effective I, with the beginning of its deliver.
In real it was an I-T! Not exact because this is a footnote.

³)When fighting especial strong armoured aircraft like IL-2, belting is up to 50% AP-ammo, but not against 4-mot bombers. This is mentioned because the Luftwaffe began fighting 4mots first with the same belting as fighting IL-2. M and I-effects had given the best results against the airframes

b) Night fighters

Like a) only with –NT instead of –T.

NT = night tracers, German: Glimmspur = glowtrace. Glowing in the meaning of kinda open fire like a glowing cigarette. Not in the meaning of light and heat like glowing metal. This is glühen, not glimmen, in German.

It should be noted that the ammo for schraege Musik was M only, for 2 and 3 cm

c) Bombers, airgrounds and fighters against ground targets and amphibious operations

10 x HEI-T wo sd
10 x M wo sd
1 x API ph wo sd
1 x APHE wo sd

When wo sd ammo is not in stock, w sd ammo can be used, but is not to be fired above 800m level flight
To prevent self destruction before hitting.

d) Aircraft fighting merchants and light combat vessels ships

1 x HEI-T wo sd
1 x APHE wo sd
1 x API elektron 90% magnesium and 10 % aluminium wo sd

(2) 15 mm weapons MG 151, MG 151 El

a)
4 x HEI-T wo sd
1 x AP-T wo sd

b) Tank hunters and airgrounds only belt when fighting tanks APC/H core of special hardened steel and jacket of alloy for the I-effect when melting during AP
For the MG 151 El this was the only ammo manufactured at this time.

(3) 13 mm weapons MG 131 in the descriptions of the cartridges themselves in LDV 4000/10 the ammo has the El-addition

a)
1 x AP-T wo sd
2 x HEI-T wo sd
Always AP-T is belted at first round for security reasons, because the first shot goes through the muzzle seal cap

b) as moveable defence weapons bombers etc.
1 x AP-T wo sd
1 x HEI wo sd printig error, should be HEI-T, because HEI nonexistent.
1 x HE-T EX w sd
Yes! EX = training ammo!
Because of belting the EX ammo, which sd after 700m, a strong hindering effect is caused at the attacker.
Way cool idea! Shock the enemy with EX-ammo popping off in the air and let’s rain the splinters on him!

(4) 3 cm weapons MK 101, MK 103

The MK 101 ammo could be changed in El-ammo for MK 103 by changing the mechanical primer screw C/33 against the electrical primer screw C/23

a)
1 x HE-T wo sd
1 x M-T wo sd
1 x APHE-T wo sd
or
1 x APHEI-T wo sd
Yes! This one has it all!
In original: Panzerbrandsprenggranatpatrone L’spur o. Zerl.
That is: Armourfireblowoffgrenadecartridge T’er wo. Det. So we are. Even for me as native it have to be careful to decipher the ingredients right.

b) Aircraft fighting merchants and light combat vessels

1 x HE-T wo sd
2 x API elektron wo sd
1 x APHE-T wo sd
or
1 x APHEI-T wo sd

c) Night fighters belt only
M-NT wo sd

d) Aircraft, which are only used fighting locomotives chuff-chuff belt only
APHE-T wo sd
or
APHEI-T wo sd

e) Aircraft fighting tanks belt only
APCBC-T/H wo sd

(5) 3 cm weapons MK 108

a) Day- and nightfighters belt only
M El wo sd
If not in stock, also M-T El res. M-NT El could be belted. All other ammo is prohibited, because of no effect.

(6) 7,9 mm onboard weapons

a) MG 17 fighters
5 x AP imp
4 x API imp
1 x B imp B = Beobachtungspatrone = observation cartridge, comparable to a small only -I-round, with phosphorus filling and impact fuse, 2mm sheet metal sensitive. Used to control hits on target via the bright phosphorus ignitions, because Luftwaffe used no traces for this. Reasons:
The lighter tracer rounds fly a different path and mislead the pilot.
The pilot should be forced to aim correctly and surprise the enemy with the fire. Not steering long bursts into the enemy via tracers to warn the enemy and consume lots of ammo.


and before the last 50 rounds as ammo-counter:

10 x AP-T 100/600 imp day or round ignites at 100m, to reduce mislead and blinding, burns till 600m
10 x Ap-NT imp night 0/700

imp improved v=verbessert, new propellant for higher V° and greater AP-capability

b) MG 17 aigrounders, MG 81 movable and in pods, MG 15

2 x AP
2 x AP-T 100/600
res.
2 x AP-NT on night missions 0/700
2 x API interchanging with 1 x API and 1 x B

7,9 API- and B-rounds contain phosphorus, the bigger API’s phosphorus or electron, the bigger HEI’s and APHEI’s a electron-thermit filling like I-bombs, the I’s a not defined fix pressed in incendiary, through a percussion cap sensitive against 2mm cardboard, spraying minimum along 10m of its way the incendiary out of the front of the grenades.

thanks for translation, and, i think, this quote sometimes very well confirms what i wanted to write and found about ammo belts for german fighters...

well, attached pic plus here fw 190 in 44?, here bf 109 from jg-54, here bf 109 from jg-27, here again 109 from jg-54 (only HEI-I-M? similar ammo belt, from excavations in north of russia), here fw 190 with field mod and fiters, here 109 with only APs for mg 151?, here mg131s of fw 190 (mainly, APs?), here 109 from jg-26 (mainly, HEI-I-M?), here hs-129 with mainly? APs...

ie, at least, just need 2 differents belts with mainly APs (against some ground targets and il-2s) and with mainly HEI-I-M (against planes, soft ground targets etc) or something like this, and it's apparently not hard to do...

I don't think it's possible to model individual bullets in IL-2.

For that reason, it might be impossible for players to choose customized ammo loadouts.

OTOH, it doesn't seem like it would be that much trouble to add different "stock" MG loadouts for different missions.

Another MG option, which could be a GUI option rather than a loadout option, would be the option to change the color of tracers or have different colored tracers at the end of the MG's load (used by some units).

Something that could be an option, but is technically a loadout, would be to change the frequency of tracer rounds. Some units didn't use tracers at all, some used more than the standard number as substitutes for incendiaries.

Every bullet is currently modelled and has been since the beginning of IL-2... they are just not rendered visually so I suppose it's possible but I don't think it's practical. Bullets are basically invisible while moving anyways which is why tracers are used.

Every gun has a pre-programmed belting list. Some, like the .50cal, recently received changes to the belting. What would be great would be to (at the least) select from a list of historically accurate belting options. The groundwork is there but I imagine it's a bit more difficult than it may appear.

It would be a really nice feature, I like it in CloD.

I agree. Visually modelling every single bullet fired requires far more resources than is reasonably practical, and is a pointless exercise since you're not going to be able to actually see a tracer-less bullet being fired. It's common sense to visually render the tracers only, while mathematically accounting the effects of all rounds fired.

Even non-tracer bullets are still actually being fired from muzzle and travel trough space in same way as tracers do, they just can't be seen, same as IRL.

what strange, i never saw any impressions or comments about these new belts, ie now better, or what...

and, by the way, in last patch for warthunder was realised ammobelting and lot of different shells... i read a little, well, if not mistaken, not bad but without free choice, only "optimized belts" ie aa/ag/without tracers... and, in fact, it's almost what we written here...

It was definitely changed. It's in the patch notes and if you set Arcade=1 for the hit arrow information you can clearly see the difference between 4.10 and 4.11.

The effect is negligible although some claim it made a big difference. I always thought they were fine... so....

oh, yes, i try some last days find more full information about shells for shvak, on russian, well, in addition to this famous page - by the way, who read full version? - i found only several fragmentary references what, of course, not enough... developer who did this work for WT, apparently, how i understood, use what we have or just not writes about sources... well, something like this, at this moment...
