In practice: 10% tighter (better) horizontal dispersion and 19% more vertical spread at max range (17.2 km) than a standard battleship: about 208 m wide × 166 m tall, against 232 m × 139 m. Also on this curve (19): ARP Haruna, ARP Kirishima, Ashitaka, Daisen, Hizen, Hyūga, Hyūga W, Inamura, Ise, Ishizuchi, Iwami, Iwami B and 7 more.
ggü. Standard-BB10 % engere H · 19 % höhere V
H = horizontal, V = vertical spread. This ship's curve against the standard battleship curve, both evaluated at this ship's max range (17.2 km) with the same model as Max Horiz/Vert Disp: horizontal 208 / 232 m − 1 = -10%, vertical 166 / 139 m − 1 = +19%. Shell grouping (σ) is separate: it sets how shells bunch toward the centre of this ellipse.
Max. horiz. Streuung207,8 m bei 17,2 km
Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:
Streubreite der Granaten bei 5 km120 m
(166.7 × (10 − 2.8) / 1000 + 2.8) × 30 = 120 m. Horizontal scatter at a fixed 5 km, from the same verified dispersion model as the rows below - a knife-fight-range anchor comparable across ships.
Streubreite der Granaten bei 10 km156 m
(333.3 × (10 − 2.8) / 1000 + 2.8) × 30 = 156 m. How wide your shells scatter at 10 km, from the same dispersion model as the max-range figure above. Picking a fixed range makes this number directly comparable from ship to ship: max-range dispersion makes a longer-range gun look worse even when it's tighter at any common range. The interactive Dispersion tab on the Charts card plots the full curve from 0 to max range.
Streubreite der Granaten bei 15 km192 m
(500 × (10 − 2.8) / 1000 + 2.8) × 30 = 192 m. Horizontal scatter at a fixed 15 km, from the same verified dispersion model - the long-range anchor. Only shown when the ship's guns reach 15 km.
Max. vert. Streuung166,3 m bei 17,2 km
Vertical dispersion ellipse height at max range:
Streuungshöhe der Granaten bei 10 km98,7 m
How tall the same scatter ellipse is at 10 km. Comparable from ship to ship for the same reason as the width value above. The height/width ratio is a piecewise-linear curve through three points from the ship's own dispersion data: at 0 m, at m, and at 17198 m. Above the kink: , so .

AP-Durchschlag Nah971,1 mm auf Nahdistanz
Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity: . Matches the in-game spec card.
AP-Durchschlag Fern620,4 mm bei 17,2 km
Same formula at the ship's max firing range (17.2 km), where the shell has slowed to 563.7 m/s: .
AP-Durchschlag 5 km844 mm
AP penetration at a fixed 5 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.
AP-Durchschlag 10 km738 mm
AP penetration at a fixed 10 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.
AP-Durchschlag 15 km651 mm
AP penetration at a fixed 15 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.
AP-Flugzeit bei 10 km5,15 s
How long an AP shell takes to reach a target at a fixed 10 km, from the same numerically integrated trajectory the Charts card plots. The shell slows under quadratic air drag, , where is air density from a standard-atmosphere profile and bundles the shell's drag coefficient, caliber and mass: . That runs from a 780 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77: the game clock runs faster than real time, and that factor was measured against stopwatch runs in the Training Room. Lower is better, since a faster shell is harder to dodge and needs less lead.
HE-Flugzeit @ 10 km5,54 s
How long an HE shell takes to reach a target at a fixed 10 km, from the same numerically integrated trajectory the Charts card plots. The shell slows under quadratic air drag, , where is air density from a standard-atmosphere profile and bundles the shell's drag coefficient, caliber and mass: . That runs from a 805 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77: the game clock runs faster than real time, and that factor was measured against stopwatch runs in the Training Room. Lower is better, since a faster shell is harder to dodge and needs less lead.
HE-Durchschlag115 mm
115 mm ≈ 460 mm caliber / 4 (improved HE penetration: German BBs, Yamato-class, and a handful of others).
Verbesserte HE-DurchschlagskraftJa
This ship's HE shells use a 1/4 (~0.25) caliber-to-pen ratio instead of the standard 1/6 (~0.167) - 0.25 in this case. Lets HE pen ~115mm armor instead of ~76mm. Hits every German cruiser (150mm CL, 203mm CA) and BB (350mm+), British heavy cruisers / Lion / Nelson, a handful of other premiums.
AP-Overmatch32 mm
floor(460 mm caliber / 14.3) = 32 mm (AP auto-penetrates plating this thick or less).
AP-AOE-Radius400
AP shell over-penetration splash radius; scales with shell mass. Wickes 102mm = 3, standard 152mm CL ~ 20, Iowa 406mm ~ 270, Yamato 460mm = 400, Incomparable 650mm = 550 (max). Larger value = bigger splash damage area when AP over-pens.
