Please rework the ammunition for the 90mm M3 cannon

Do you have information about german 88mm shells? I am absolutely sure that PzGr 39 muzzle velocity should be around 800m/s.

Apparently it was for the 88mm FlaK 37 but for the Tiger it was only 773m/s.

At least that was it says in the book

Encyclopedia of German Tanks of World War Two: A Complete Illustrated Directory of German Battle Tanks, Armoured Cars, Self-propelled Guns, and Semi-tracked Vehicles, 1933-1945

In “tigerbefel” feedforward for PzGr 39 lesser than for SpGr, how it’s possible if SpGr is faster than PzGr 39 according to game and that book?

Look

Yes. Very odd. But they also put the Panzergranate 39 and 40 in the same category.

Seems like a mistake.

The first row is probably accurate for Pzgr. 40 and the second row for Sprenggranate and Pzgr. 39.

The 88mm Pzgr., Pzgr. 39 and Sprenggranate use the same amount of propellant while the Sprenggranate weighs 9kg compared to the 10.2kg of the Pzgr. 39 and the 9.5kg of the old Pzgr.

So there’s no way that the AP rounds would be faster than the HE round.

Tiger! : the tiger tank : a British view
In this book MV also mentioned as 800m/s.
APCR had big velocity draw during flight, it’s normal to have same foreforward

Not sure. It’s the same shape but lighter. Sure it would lose some velocity quicker but not that much of a difference.

According to the ammunition manual of the 8,8cm KwK 36:

Schießregel für 8,8 cm Pzgr. 40:

Das Ziel ist zielaufliegend anzurichten auf alle Kampfentfernungen bis 500 m
mit dem entsprechenden Metermarken der Pzgr. 39
Auf Entfernungen von 600 – 1000 m sind jeweils 100 m, von 1100 bis 1500 m
jeweils 200 m abzubrechen.

  1. Beispiel: Gemessene Entfernung 400 m. Das Ziel ist mit der
    400-m-Marke der Pzgr. 39 anzurichten.
  2. Beispiel: Gemessene Entfernung 1200 m. Das Ziel ist mit der
    1000-m-Marke anzurichten

So the trajectory is flatter and therefore the shell hits faster.

But how in this case PzGr39 and SpGr can have same ballistics with different MV?

Start a thread and tag Peasant. They have a ton of information about German guns.

I am too lazy. Maybe later. I am going to search allies kwk36 test report first

Also it’s arledy overtiered enough.

No, it’s super balanced :P

It was balanced on 5.7 when gajin give it stab. It became OP, so gaijin uptired it to 6.3, but after removing stab BR wasn’t lowered.

It isn’t

I agree with most of your points, but personally I find M18s to be bizarrely survivable. I still have a video somewhere of hitting the turret of an M18 from broadside at 900m on El Alamein with the Sturer Emil, which only had the effect of turning the gun a little yellow. When you have a long ass reload, that can be a little aggravating 😂

I want to point out that I also have a bug report to increase the M36’s top speed to 30 mph (48.3 km/h) as documents like “Catalog of Standard Ordnance Items, Volume I” and this seemingly official image for which I can’t find a source say that that is the top speed of the M36 and M10A1 (it’s already been acknowledged, now I’m waiting for if it gets implemented or if the devs provide a response).

Spoiler

If that bug report goes through then I really can’t see a reason for the M36 to stay at 5.7.

That’s because the 128mm has like a 19mm fuze sensitivity.
APHE that doesn’t fuze does less damage than AP, because it spalls way less and even the shell itself does less damage.
But it’s not really the norm to fire a 128mm at a M18. Especially since one is a super slow TD and the other a very fast light vehicle.

One time when I played the T-34-100 I spent all my 4 HE rounds on taking out M18s.
But in general any 75-90mm will take out an M18 in one shot.

It seems like that fuze sensitivity was adjusted to now take the effective armor into account and not just the plate thickness. So APHE with 14mm sensitivity will pretty much always fuze on M18s unless it’s a 90° side shot.

I know, although given the size of respectively the M18 turret and the 128mm shell, well… my comment at the time in regards to the commander was that soldiers must have been built different back then. :P

I wish we had actual changelogs on this stuff tbh.

Some new data on the ballistic performance of this gun:

Spoiler

this is not the full table, see more here: https://apps.dtic.mil/sti/tr/pdf/ADA954813.pdf

That’s interesting. Its too bad the 75mm AP is army standard.
