Hull dimensions ƒ
Length x beam at the waterline, plus draft. Length matters when dodging torpedoes; beam and draft shape how hard the ship is to hit.

Armor material/layer entries71
Fire resistance ƒ
top hull: 1 − 0.8335 fire coefficient = 16.6%. Lowers how often hits set you on fire. It does not reduce the damage a burning fire does per second; fires burn at the full rate on every ship.
Fire duration60 s
Fire damage ƒ
One unattended fire: 0.003 of max HP per second (0.3%) × 60 s = 0.18 of the pool; 0.18 × 35,700 HP = 6,426 HP on this ship. 4 fire points can burn at once.
Flood duration40 s
Flood damage ƒ
One unattended flood: 0.005 of max HP per second (0.5%) × 40 s = 0.2 of the pool; 0.2 × 35,700 HP = 7,140 HP on this ship.
Torp Reduction ƒ
1 − 0.272 hull torpedo-damage coefficient / 0.333 unprotected baseline = 18%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.
Magazine HP ƒ
Per-turret powder-magazine HP, a separate pool from the ship's. Penetrating hits wear it down and the turret is likelier to be knocked out as it falls, so a larger pool keeps the guns firing through punishment that silences a peer's.
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.
Effective HP ƒ
Base 35,700 HP plus everything Repair Party can restore: 0.0066 of max HP per second (0.66%) × 28 s × 35,700 HP = 6,597 HP per charge, × 3 charges = 19,792 HP. Ceiling, not a prediction: a charge only restores damage actually taken, and only the regeneratable share of it. In practice ships realize about half of this, mostly because half the charges go unspent; a charge that is used returns about 97% of the per-charge figure above.

Bow section HP ƒ
Damage saturation pool for the bow: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 2,600 = 5,200), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.
Casemate section HP ƒ
Damage saturation pool for the casemate: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 7,800 = 15,600), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.
Hull section HP ƒ
Damage saturation pool for the hull: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 36,700 = 73,400), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.
Superstructure section HP ƒ
Damage saturation pool for the superstructure: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 900 = 1,800), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. The superstructure is not exempt: it saturates exactly like the bow and stern, so shells aimed at it stop dealing full damage once this pool is used up. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.
Stern section HP ƒ
Damage saturation pool for the stern: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 3,200 = 6,400), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.
Citadel section HP ƒ
This section has no practical saturation cap: every hit here keeps dealing its normal share of damage (on most ships the citadel; on many destroyers the casemate).

Turret traverse4 °/s
Turret armor280 mm
Turret traverse arcs ƒ
How far each mount can train, in degrees to either side of the mount's own facing. A rear turret with ±150° leaves a 60° blind wedge over the bow; one-sided arcs are wing mounts that cover a single side. The data does not say which way each mount faces, so the arcs are listed per mount without bow/stern angles.
Guns to bear ƒ
180° − 133° (the most restricted aft-facing mount's arc) = 47° off bow; 180° − 140° (the most restricted forward-facing mount's arc) = 40° off stern. How far off the bow (or stern) the ship must angle before every main turret can fire: the widest blind wedge among the rear-facing (or forward-facing) mounts, from each mount's trainable arc.

Dispersion type ƒ
In practice: 1% wider (worse) horizontal dispersion and 1% more vertical spread at max range (14.6 km) than a standard battleship: about 209 m wide × 125 m tall, against 206 m × 124 m. Also on this curve (55): AL Vittorio Veneto, Alsace, Andrea Doria, BA Binah, BA Tirpitz, Bayern, Bismarck, Bismarck B, Brandenburg, Bretagne, Cavour, Cristoforo Colombo and 43 more.

Secondary DPM (per side) ƒ
Sum across all secondary families of (per-side barrels × 60 / reload_s × alpha), with each reload counted in whole 1/7 s ticks (guns fire on the first tick after the reload), where per-side barrels = mounts × barrels-per-mount / 2 (the guns that bear on one broadside target). Per-family: 12×1 150 mm (6/side) × 60/10 s × 2200 = 79,200. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).
Secondary fire DPM vs T4 BB (per side) ƒ
Fires/min (per side) 4 × (1 − 0.166 fire resistance) × 60 s × 0.003 of max HP per second × 48,200 HP = 28,654. Per side: the barrels that bear on one broadside target (mounts × barrels / 2). A ceiling: assumes every shell hits and ignores the four-fire cap and Fire Prevention.
Total secondary DPM vs T4 BB (per side) ƒ
Secondary DPM (per side) 79,200 + secondary fire DPM 28,654 = 107,854: shell damage plus fire damage against one T4 battleship, every shell hitting.

Maximum speed21.5 kt
Turning circle radius530 m
Rudder shift time11.5 s
Engine power-boost threshold7.0 kt
Engine spool-up time23 s
Reverse spool-up time11.5 s
Reverse speed ƒ
top speed / 4 + 4.9 = 21.5 / 4 + 4.9 = 10.3 kt. Base value; speed modifiers scale it.
Crash stop ƒ
Seconds from top speed to a dead stop after ordering full reverse: reverse power winds in over the reverse spool-up while water drag does most of the braking, using the ship's own reverse-power ratio. The full curve is on the acceleration chart. Full reverse stops about a quarter faster than a plain Stop order from top speed.
Engine boost threshold (reverse) ƒ
Speed below which the engine's built-in power boost applies in reverse.
Acceleration 0-90% ƒ
Time to reach 90% of top speed (19.4 kt of 21.5 kt).
Acceleration 0-99% ƒ
Time to reach 99% of top speed (21.3 kt of 21.5 kt). 99% rather than 100% because true top speed is asymptotic (thrust meets drag), so the last fraction of a knot is never quite gained.
Guns in a full turn ƒ
With the rudder hard over the hull turns 4.4°/s, so a target drifts across the bow at that rate. Turret traverse minus hull turn: 4 − 4.4 = -0.4°/s, so the guns fall behind and catch up once the turn eases. Main Battery Mod. 2 (+20% traverse) and Mod. 3 (−15%) move this line.
Detectability by sea ƒ
Base value, no camouflage. With a Grade IV permanent camo (or any disposable camo): 12.5 km x 0.955 = 11.94 km. Camouflage does not change detectability by air.
With Grade IV camouflage (sea) ƒ
Detectability by sea 12.5 km x 0.955 (Grade IV permanent camo or any disposable camo) = 11.94 km.
Detectability by air10.2 km
Smoke firing penalty9.54 km
Detect when firing (sea) ƒ
max(main battery range, sea detectability 12.5 km) = 14.6 km. Equal to the ship's main battery range (never below base detectability): firing makes you visible to everyone you can reach.
Detect when firing (air) ƒ
Air detectability 10.2 km + gun-firing bloom 6.1 km = 16.3 km. The bloom tracks main-battery caliber 305 mm × 0.020 = 6.1 km.
Detect when on fire (sea) ƒ
Sea detectability 12.5 km + 2.0 km while burning = 14.5 km.
Detect when on fire (air) ƒ
Air detectability 10.2 km + 3.0 km while burning = 13.2 km.
