Dunkerque discussion

It is implemented :) Including the armor in the middle of the turret (tricky to see it, you have to clip into the turret with Nvidia Ansel, but it’s there).

So, the vessel is released on the dev server, and… it’s layout makes it super-easy to ammo-rack from almost any angle by pretty much every single BR 7.0 AP shell.

🤦‍♂️☠

It’s survivability is effectively zero in 1 vs 1 against any BR 7.0 battleship or battlecruiser.

BUT plenty of other battleships have ammo racks that can be depleted - perhaps this is our solution for the problem, as she stores magazines and shell rooms side by side, so they could just make it depelte the upper magazine and shell room first, and only then use the lower one.

There is also a bug report about the lack of pen of the SAP shell :
https://community.gaijin.net/issues/p/warthunder/i/IpFPSqCeC7hI

540mm of pen a 1000 is just blasphemous, if anyone can find or have a proper french source for the 330 mm/50 (13") Model 1931, please let them know !!!

Here you go once again, the good old Gajin hate for French TT…

So someone litteraly called the french “Services Historique de la Defence” and they answered they don’t have any numbers about the AP values … (Basically we are scewed Gajin Devs will do what they want)

Then the topic shifted towards the fact that the shell is identified as a SAP shell but IR it is more or less an APCBC shell and most likely acted like one, even the germans classified it as an AP shell.

But a Bug Reporting Manager brushed aside in the old cold fashioned way this idea, because “YoU Don’T HaVE SouRcES”:

The game uses its on calculator anyway. Proving that the shell was APCBC, instead of SAPCBC would be more effective.

It’s a good point, but I searched through 10 different books, and NONE of them point to the shell being either SAPCBC or APCBC.

Everyone just call it “Armor-piercing” (as is the shell designation - Obus Perforant / OPf).

As far as my awful translation skills go, Les cuirasses Dunkerque et Strasbourg by Robert Dumas also calls it simply the Obus Perforant.

That whole “it’s SAP shell” seems to come from NavWeaps’ original research, not backed by any sources. On a purely factual level, it might be correct, I do not have the competency to judge that.

But it seems quite inconsistent given that Izmail’s shells are marked as HE (not even HE-BF), because that’s what is in the Russian sources, even though effectively they are SAP (see the table at the end of this comment). Yet Dunkerque’s shells are AP in the French sources, and yet, we don’t get them marked as AP. 🤔

Whether the % of explosive filler in the shell is high enough to suggest these are SAPCBC is also highly debatable, I think.

(Image of the Dunkerque’s 330 mm from the French Battleships, 1922–1956 by John Jordan and Robert Dumas showing the cap and ballistic cap (CBC) part of the shell)

If we’re playing with doing the original research, like NavWeaps did, here’s a table of a number of shells of somewhat comparable calibres that we already have in the game, and the percentage of the HE filler:

Gun Clibre In-game shell type Total mass Mass of the bursting charge %
330 mm/50 Model 1931 330 HE 522 63,5 12,16%
12-inch/52 pattern 1907 305 SAPCBC 470,9 55,2 11,72%
36 cm/45 Type 41 356 SAPCBC 635,58 68,64 10,80%
14-inch/52 pattern 1913 356 HE (Izmail) 732 75,85 10,36%
12 inch/50 Mark XI 305 SAPCBC 386 36,3 9,40%
SK L/45 380 SAP 750 67,1 8,95%
12-inch/50 Mark 8 305 HE (Alaska) 426,38 35,31 8,28%
13.5 inch/45 Mark 5(H) 343 SAPCBC 635 50,3 7,92%
14 inch/45 Mk.12 356 HE (Texas) 635 47,62 7,50%
330 mm/50 Model 1931 330 SAPCBC 560 20,3 3,63%
305 mm/50 SK L/50 305 APC 405,5 13,6 3,35%
SK L/45 380 APCBC 750 25 3,33%
13.5 inch/45 Mark 5(H) 343 APCBC 635 20,2 3,18%
12 inch/50 Mark XI 305 APC 389,8 12 3,08%
12 inch/50 Mk.7 305 APC 394,62 11,34 2,87%
12-inch/52 pattern 1907 305 APCBC 470,9 12,96 2,75%
305 mm/50 SK L/50 305 SAP 410 10,8 2,63%
305 mm/54 B-50 305 APCBC 470,9 12,2 2,59%
14 inch/45 Mk.12 356 APCBC 635 15,55 2,45%
13.5 inch/45 Mark 5(H) 343 APCBC 639,6 15 2,35%
12-inch/50 Mark 8 305 APCBC 517 7,89 1,53%

I don’t know about you, but the Dunkerque’s shells have a more typical filler for the AP rounds the the SAP. Yes, it is on the high end of the AP - as multiple sources directly state - but it seems to be more of an AP round none the less. 🤷‍♂️

Heck, now that I look at these numbers, I have more questions about HE shells from USS Texas and SAP shells from 305 mm/50 SK L/50 than I do about Dunkerque’s being APCBC 👀

It’s getting severely screwed on the penetration values.

That is a result of handling rooms below the barbette being included as part of the magazine/shell room’s hitboxes. This allow shells penetrate the barbette to detonate magazines with blast and splinter damage. In this case her citadel armour becomes irrelevant. She’s not the only ship having this problem but she’s certainly one of the most severely affected ones.

I’m not sure what you are referring to. Would you be so kind and elaborate / capture a picture in the x-ray view of what I should be looking at?

Because what I see in the X-ray seems to be matching the plans from French Battleships, 1922–1956 and Les cuirasses Dunkerque et Strasbourg pretty much spot-on. In the game there is no ammo directly in the ammo elevators.

Do you think someone gets paid extra to make naval bad? People really want to like it, and Gaijin goes out of their way to screw it up.

It has more to do with the facts that Gajin Devs can’t help themselves but bash anything French related even when they try not to, If they ever try.

Making up stats for ships that never sailed, with magical numbers: Check

Accept a little detail that may help a ships that look terrible on the Dev Server and so mabye make it more attractive and competitive: Nuh uh

They have full controll on what a vehicle has to be in-game, It’s challenge impossible to change their minde.
I just can’t take their acts of bad faith and gaslight anymore, They are sooo predictable.

Anyway If someone has a 330 mm/50 1931 OPf that’s rusting in it’s atics, It’s maybe time to shine!

It looks like there are some ammo in the elevator, at least in the plans. But I don’t know of it model in game.

Yea, that same graphic is in the Les cuirasses Dunkerque et Strasbourg - my interpretation is that it just illustrates the process, it doesn’t mean that the ammunition handling procedures on the vessels allowed for the shells to be being permanently stored in the elevator. Also, I said “In the game there is no ammo directly in the ammo elevators.”

HK says that the “handling rooms below the barbette being included as part of the magazine/shell room’s hitboxes. This allow shells penetrate the barbette to detonate magazines with blast and splinter damage”

But the way Gaijin implemented it, seems to be actually quite beneficial to the vessel, as I do not see her to store any ammo in the elevators (barbettes or directly below the barbettes), so I’m not sure what he is referring to.

I think he refer to this discussion about the shell room:

Where they talk about shell room under the barbette exploding on the american BB iirc.

The visual appearance of the X-ray model is not relevant to the hitbox’s dimension. The space you’re looking at is part of the hitbox of the magazine and shell room even if there’s nothing visually present there.

You can inspect the actual hitbox of modules in CDK:
