Fire resistance ƒ
stock hull: 1 − 0.7336 fire coefficient = 26.6%; top hull: 1 − 0.7003 fire coefficient = 30%. 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 duration30 s
Fire damage ƒ
One unattended fire: 0.003 of max HP per second (0.3%) × 30 s = 0.09 of the pool; 0.09 × 35,600 HP = 3,204 HP on this ship. 4 fire points can burn at once.
Flood duration40 s
Flood damage ƒ
One unattended flood: 0.0025 of max HP per second (0.25%) × 40 s = 0.1 of the pool; 0.1 × 35,600 HP = 3,560 HP on this ship.
Torp Reduction ƒ
1 − 0.28 hull torpedo-damage coefficient / 0.333 unprotected baseline = 16%. 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.

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 × 2,500 = 5,000), 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.
Auxiliary section HP ƒ
Damage saturation pool for the auxiliary room: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 3,000 = 6,000), 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 × 26,700 = 53,400), 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 × 2,300 = 4,600), 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 ×. 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 × 2,900 = 5,800), 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 ×. 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 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° − 142° (the most restricted aft-facing mount's arc) = 38° 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.

Maximum simulated damage ƒ
Initial: 41,200 × 0.333 = 13,733 → 44,200 × 0.333 = 14,733 (warhead alpha × saturation coefficient, stock → upgraded torpedo). Most targets only intersect one hull section, so a hit transfers about 1/3 of the warhead alpha (2/3 when the warhead blast >= 5000 and the burst reaches a second section). For this ship: . In battle, a hit on the torpedo belt deals the per-hit figure × (1 − the target's torpedo protection %), a bow or stern hit deals it in full, and a torpedo never counts as a citadel hit.
Maximum damage (ammunition) ƒ
44,200 warhead alpha / 3 + 1,100 blast = 15,833. Warhead alpha / 3 plus the blast addend: the per-torpedo damage figure. The 'Maximum simulated damage' row above applies target geometry to the same warhead.
Torpedo module damage ƒ
Per-torpedo module/blast damage parameter. Most torpedoes carry 500 to 2,000; ships announced by WG as dealing increased module damage carry 9,000 to 12,000, so their hits knock out engines, rudders, and turrets far more often. Comparative figure.
Torpedo detectability1.3 km
Reaction time ƒ
How long a target has to dodge after your torpedo is spotted at its detectability range (lower means less warning): . 2.6855 converts knots to m/s on the game clock. Base value; commander torpedo-concealment skills lower it further.
Flooding chance ƒ
This torpedo carries a flooding-chance value of 2.46 per hit, shown as . Values above 100% are normal: in battle the base chance is scaled down by the target's torpedo protection (the Torp Reduction stat on its Survivability card) and any flood-resistance modifiers, so a value above 100% keeps flooding likely even through partial protection.

AA explosions ƒ
Each ~2 s salvo fires 2 AA explosions in quick succession, each leaving 2 clouds ahead of the attacking squadron - up to 4 clouds per salvo × 170 damage each. Planes that fly into a cloud take its damage; clouds dissipate before the next salvo lands. Defensive AA Fire, where fitted, multiplies the AA explosions within each salvo, and commander skills that raise the Number of AA explosions add to it.
Cloud damage ƒ
Damage a plane takes for flying into one flak cloud, before any reductions.
Cloud spawn chance ƒ
Each cloud in the pattern rolls this chance to spawn, so salvos average fewer clouds than the maximum. Often called flak 'hit chance', but spawned clouds always damage planes that fly into them - the roll is on spawning.
Salvo interval ƒ
A new flak salvo (the AA explosions above) fires roughly every 2 s.
Fired by ƒ
Flak keeps firing while at least one secondary battery mount is operational - even losing every dedicated AA mount does not stop it.
Flak zone ƒ
The activation band: flak fires while attacking planes are inside it. Clouds are placed ahead of the planes' path, so clouds can land short of 2.5 km or past 5 km - once planes get inside the band, new salvos stop. AA range bonuses push the outer edge out; the 2.5 km inner edge does not move.

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: 6×2 100 mm (6/side) × 60/4 s × 1400 = 126,000. 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 T6 BB (per side) ƒ
Fires/min (per side) 5.4 × (1 − 0.3 fire resistance) × 60 s × 0.003 of max HP per second × 59,350 HP = 40,382. 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 T6 BB (per side) ƒ
Secondary DPM (per side) 126,000 + secondary fire DPM 40,382 = 166,382: shell damage plus fire damage against one T6 battleship, every shell hitting.

Reverse speed ƒ
top speed / 4 + 4.9 = 32.5 / 4 + 4.9 = 13.0 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 (29.2 kt of 32.5 kt).
Acceleration 0-99% ƒ
Time to reach 99% of top speed (32.2 kt of 32.5 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 5.7°/s, so a target drifts across the bow at that rate. Turret traverse minus hull turn: 7 − 5.7 = +1.3°/s, so the guns hold the target through the turn. Main Battery Mod. 2 (+20% traverse) and Mod. 3 (−15%) move this line.
