All values are ship base stats with modifications and upgrade changes denoted inline.
Survivability
Hit Points19,000

Armor range10–16 mm
Plate armor thicknesses10, 15, 16 mm
Armor material/layer entries24
Fire resistance30%
Fire duration30 s
Torp Reduction0%
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.
Main Battery

Mounts / barrels5 mounts / 5 barrels
Reload time5.5 s

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 = (10738/30·(8−0.5)/1000 + 0.5)·30 = 95.5 m
Max Vert Disp ƒ
Vertical dispersion ellipse height at max range = max horizontal × radiusOnMax = 95.5 × 0.6 = 57.3 m
Med Horiz Disp ƒ
50%-hit horizontal radius = max horizontal × GetHalfHitsRatio(σ) = 95.5 × 0.319 (σ=2) = 30.5 m
Med Vert Disp ƒ
50%-hit vertical radius = max vertical × GetHalfHitsRatio(σ) = 57.3 × 0.319 (σ=2) = 18.3 m
Turret turn time ƒ
180 degrees / 12 deg/s traverse speed = 15 s.
Base shells/min ƒ
5 broadside guns x 60 / 5.5 s base reload = 54.5.
HE shells
HE Damage2,200
HE Velocity700 m/s
Fire Chance9%
HE penetration ƒ
23 mm ≈ 139 mm caliber / 6 (standard HE penetration ratio).
HE full-salvo alpha ƒ
2,200 HE damage x 5 broadside guns = 11,000.
Base HE DPM ƒ
11,000 HE full-salvo alpha x 60 / 5.5 s base reload = 120,000.
Base fires/min ƒ
5 HE shells x 60 / 5.5 s reload x 9% fire chance = 4.91.

Min Ricochet60 deg
Guaranteed Ricochet75 deg
Fuse Timer0.03 s
Fuse Threshold25 mm
AP overmatch ƒ
floor(139 mm caliber / 14.3) = 9 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 points6
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: (33×3.5×1) + (6×3.5×0.95) = 135. 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.
