Gaijin doesn’t seem to understand that any armor can be penetrated with enough speed — whether it’s a ballistic vest or ship armor. I thought that was common knowledge. For example, in the USN empirical formula, velocity is raised to the power of 1.1, while mass is only raised to 0.55.
Compare Okun’s calculations to what Gaijin uses — just look at the penetration ratios of the shells they’ve modeled. It’s clear as day.
Figures at 0 meters and 14,600 meters (almost 15,000), all versus British Cemented Armor, for example — and effective pen (shell not broken):
- Yamato: 31.7 and 19.3
- Iowa: 32.8 and 21
- Bismarck: 31.1 and 18.5
- Richelieu: 32.9 and 18.8
- Roma: 31.9 and 20.4
Gaijin’s values (first one for 1000 m):
- Yamato: 870 and 630
- Iowa: 857 and 583
- Bismarck: 708 and 439
- Richelieu: 738 and 491
- Roma: 771 and 513
You get it, right?
In the end, it’s clear the Germans are nerfed — as usual — in this ‘game’.
Iowa and Yamato obviously have overestimated penetration values. Or, more likely, the 380 mm guns are heavily underrated.
Iowa’s penetration matches what’s in Battleships: United States Battleships 1935–1992, calculated using the USN empirical formula. But using the same formula, Bismarck’s penetration is actually significantly higher.
Double standards, perhaps?
That formula gives more weight to velocity than to shell mass.
Yet in Gaijin’s model, Richelieu — with the same caliber, 10% more shell mass, and 2.5% less velocity — has higher penetration.
According to Okun, close-range penetrations are nearly identical across these calibers, but heavier shells lose velocity more slowly — which makes sense.
So either the penetration values for the 406–460 mm guns are inflated (except for Rodney’s 406 mm for some reason — although SS also show inflated values in the same pattern), or the 380 mm guns are massively underrated — most notably Bismarck’s.
And all these ships will be matched against each other anyway — as we all know, BR 8.7 vs. 8.3 makes no real difference
Now let’s talk about the Sovetsky Soyuz.
Its shell, with the same caliber and penetration on par with Iowa’s, somehow has twice the explosive filler. And it’s also significantly faster. How is that even possible??
And its semi-AP shell is somehow more powerful than comparable HE shells — while still having penetration close to that of 380 mm AP shells. What kind of magic is this?
