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 entries50
Fire resistance ƒ
top hull: 1 − 0.6004 fire coefficient = 40%. 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 × 44,000 HP = 3,960 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 × 44,000 HP = 4,400 HP on this ship.
Torp Reduction ƒ
1 − 0.32 hull torpedo-damage coefficient / 0.333 unprotected baseline = 4%. 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 44,000 HP plus everything Repair Party can restore: 0.02 of max HP per second (2%) × 20 s × 44,000 HP = 17,600 HP per charge, × 2 charges = 35,200 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 × 1,500 = 3,000), 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 × 6,600 = 13,200), 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.
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 × 33,000 = 66,000), 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.
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 × 2,400 = 4,800), 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 × 2,700 = 5,400), 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).
These main guns are dual-purpose: they also fire at aircraft and feed the AA Defense card.

Reload time6 s
Firing range15.5 km
Turret traverse25 °/s
Turret armor127 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° − 148° (the most restricted aft-facing mount's arc) = 32° off bow; 180° − 148° (the most restricted forward-facing mount's arc) = 32° 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.
Shell Grouping (σ)2.05
Dispersion type ƒ
In practice: the baseline curve for a standard cruiser -- at max range (15.5 km) shells land in an ellipse about 140 m wide and 84 m tall. Also on this curve (215): AL Baltimore, AL Chapayev, AL Cheshire, AL Harbin, AL Montpelier, AL Tallinn, AL Zara, Aberdeen, Accord, Agano, Albemarle, Algérie and 203 more.

SAP Fragment Radius ƒ
SAP shell fragment splash radius; the area over which a SAP hit scatters fragment damage. Scales with shell mass (90mm ~ 5, 203mm CA ~ 20-30, 320mm = 175, 406mm = 250, 457mm = 400, max) and is tuned per ship, so two ships with the same SAP caliber can differ (135mm ranges 5-24). Larger value = wider fragment spread per hit.
SAP full-salvo alpha ƒ
3,500 SAP damage x 10 broadside guns = 35,000.

AA explosions ƒ
Each ~2 s salvo fires 2 AA explosions in quick succession, each leaving 3 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between salvos - up to 7 clouds per salvo × 260 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 main 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 6 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.

Turning circle radius740 m
Rudder shift time8.5 s
Engine power-boost threshold7.0 kt
Engine spool-up time15.3 s
Reverse spool-up time7.7 s
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 5.3°/s, so a target drifts across the bow at that rate. Turret traverse minus hull turn: 25 − 5.3 = +19.7°/s, so the guns hold the target through the turn. 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): 12.54 km x 0.955 = 11.98 km. Camouflage does not change detectability by air.
With Grade IV camouflage (sea) ƒ
Detectability by sea 12.54 km x 0.955 (Grade IV permanent camo or any disposable camo) = 11.98 km.
Detectability by air7.64 km
Smoke firing penalty6.26 km
Detect when firing (sea) ƒ
max(main battery range, sea detectability 12.54 km) = 15.48 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 7.64 km + gun-firing bloom 3.04 km = 10.68 km. The bloom tracks main-battery caliber 152 mm × 0.020 = 3.04 km.
