All values are ship base stats with modifications and upgrade changes denoted inline.
Survivability
Hit Points28,400
Displacement9,304 t
Armor range7–90 mm
Plate armor thicknesses7, 9, 10, 16, 20, 25, 30, 40, 50, 52, 53, 90 mm
Armor material/layer entries61
Fire resistance30%
Fire duration30 s
Torp Reduction10%
Magazine HP ƒ
The magazine is the module a detonation comes from. Penetrating hits to it raise the detonation chance from 1% toward 30% as its HP is worn down, so a larger magazine pool rides out citadel hits longer before a detonation becomes likely.
Steering gear HP ƒ
Durability of the steering gears. As this pool drops, hits are likelier to jam the rudder; unlike most modules the steering can be knocked out and repaired but is never permanently destroyed.

Mounts / barrels2 mounts / 8 barrels
Reload time10 s
Firing range14.5 km

Shell Grouping (σ) ƒ
Shell grouping (sigma); shown in-game as Shell Grouping.
Max Horiz Disp ƒ
Horizontal dispersion ellipse width at max range. (R/30·(idealRadius−minRadius)/idealDistance + minRadius)·30 = (14475/30·(8−1.1)/1000 + 1.1)·30 = 132.9 m
Max Vert Disp ƒ
Vertical dispersion ellipse height at max range = max horizontal × radiusOnMax = 132.9 × 0.6 = 79.7 m
Med Horiz Disp ƒ
50%-hit horizontal radius = max horizontal × GetHalfHitsRatio(σ) = 132.9 × 0.32 (σ=2) = 42.5 m
Med Vert Disp ƒ
50%-hit vertical radius = max vertical × GetHalfHitsRatio(σ) = 79.7 × 0.32 (σ=2) = 25.5 m
Turret turn time ƒ
180 degrees / 12 deg/s traverse speed = 15 s.
Base shells/min ƒ
8 broadside guns x 60 / 10 s base reload = 48.
HE shells
HE Damage2,100
HE Velocity995 m/s
Fire Chance7%
HE penetration ƒ
25 mm ≈ 152 mm caliber / 6 (standard HE penetration ratio).
HE full-salvo alpha ƒ
2,100 HE damage x 8 broadside guns = 16,800.
Base HE DPM ƒ
16,800 HE full-salvo alpha x 60 / 10 s base reload = 100,800.
Base fires/min ƒ
8 HE shells x 60 / 10 s reload x 7% fire chance = 3.36.

AP overmatch ƒ
floor(152 mm caliber / 14.3) = 10 mm (AP auto-penetrates plating this thick or less).

Per-side salvo damage ƒ
per-side salvo x per-torpedo simulated damage.
AA Defense
AA mount points8
Close-range AA DPS ƒ
Sum across every AA aura on this ship of (aura.continuous_damage x 3.5 x aura.hit_probability). Here: (28×3.5×0.9) + (12×3.5×0.85) + (32×3.5×0.9) = 225. Covers AA-only mounts plus dual-purpose secondaries (Bismarck 105mm, USN 5"/38 cruiser secondaries) and dual-purpose main batteries (Sumner-class 5"/38, Akizuki-line 100mm). Formula validated against in-game captures on California, Sumner, Manfred von Richthofen, Dante Alighieri (exact) and within +/-17% on the remaining verified ships.
Maximum AA range ƒ
Longest-reaching aura across AA-only + dual-purpose auras.

Secondary dispersion type ƒ
Max dispersion = range (km) × 57 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.
Max secondary dispersion @ 4.5 km ƒ
4.5 km × 57 + 30 = 286.5 m.
