Overview

Kotovsky is a Tier IV Soviet light cruiser whose 152mm guns earn citadels on broadsides (168,000 AP DPM), with Sonar as her vision tool: Hydro lets her contest islands and smoke without exposing the hull. Standout traits: best armor plate in T4 CAs (150 mm) and end-plate armor (16 mm).

Positioning

Sit 12-15 km from a contested cap where an island shadows you from the opposite battleship line. Hydro (3.7 km on ships, 2.7 km on torpedoes) lights up DDs and incoming torpedoes inside its bubble, so you can push the cap edge from cover without taking the spotting cycle; prefer cover positions over open-water flanks. A 850 m turning circle is wide for her cohort, so a committed turn gives up a lot of water; plan course changes a salvo ahead.

Potato Avoidance

Pushing in blind because the kit says brawler

3.7-km Sonar is what makes the close fight winnable, and it only helps once you are already committed; it does not tell you what is waiting two islands over. Push when a destroyer is lit or a teammate holds vision, not to find out who is there.

Ships whose client entry holds only the 260 x 20 m placeholder use a curated real-world figure instead, and any ship we have no trustworthy size for omits this row rather than print the placeholder.

Fire resistance

Does not reduce the damage a burning fire does per second: replay-measured burn ticks run at the full rate on every ship. By elimination it lowers how often hits set you on fire; ignition-rate replay data is consistent with that but too confounded by attacker mix to measure the reduction directly.

Initial: 13.3% → 16.6%

Fire duration30 s

Fire damage

Each fire ticks 0.3% of max HP per second for the full 30 s, so one unattended fire burns 9% of the pool (2,313 HP on this ship). 4 fire points can burn at once. Verified against measured burn ticks in replay data.

0.3% of HP per second

Flood duration40 s

Flood damage

A flood ticks 0.25% of max HP per second for the 40 s duration, so one unattended flood costs 10% of the pool (2,570 HP on this ship). Verified against measured flood ticks in replay data.

Torp Reduction

Reduces torpedo hit damage. Replay data shows no effect on floods: flood ticks run at the full rate and flood frequency does not decline with protection.

10%

Magazine HP

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.

Turret traverse arcs

How far each mount can train, in degrees to either side of the mount's own facing, read from in-game data. 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.

2x ±155°, 2x ±146°

Guns to bear

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. Mount facing is inferred from turret stations and verified against known layouts, including Izumo's aft-facing forward turret.

= 10^{- 7} \cdot 2300 \cdot {51.5}^{0.69} \cdot {0.152}^{- 1.07} \cdot 880^{1.38} = 303.2 mm

Maximum simulated damage

Estimate of WG's in-game value; matches the in-game port screen within ±5%. Saturation: most targets only intersect one hull section, so the sim transfers ~1/3 of the warhead alpha (2/3 when the warhead blast >= 5000 and the burst reaches a second section). For this ship:

D_{sim} = α \cdot c = 40, 200 \cdot 0.333 = 13, 400

≈ 13,400

Maximum damage (ammunition)

The ammunition card's 'Maximum Damage' stat, exact: warhead alpha / 3 plus the blast addend. This is the per-torpedo number most references quote; the 'Maximum simulated damage' row above is WG's separate geometry-sim stat from the launcher spec panel.

14,400

Torpedo detectability1.3 km

Reaction time

How long a target has to dodge after your torpedo is spotted at its detectability range (lower means less warning):

t_{react} = \frac{1.3 km}{64 kt \times 2.6855} = 7.6 s

. The 2.6855 m/s-per-knot game-speed factor is calibrated from in-game measurement; the community's traditional 2.6 reads about 3% slower. Base value; commander torpedo-concealment skills lower it further. Community torpedo-reaction calculator by u/LorenDovah and u/The_ColorOutofSpace.

7.6 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 2.4 per hit, shown as

2.4 \times 100 = 240 %

. Torpedo flood 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. Not shown on the in-game port screen.

Bursts

Each ~2 s wave fires 2 quick salvos of 1 clouds ahead of the attacking squadron - up to 2 clouds per wave × 140 damage each. Planes that fly into a cloud take its damage; clouds dissipate before the next wave lands. Defensive AA Fire, where fitted, multiplies the salvo repeats within each wave.

2 salvos × 1 clouds

Cloud damage

Damage a plane takes for flying into one flak cloud, before any reductions.

Cloud spawn chance

Each cloud in the pattern rolls this chance to spawn, so waves 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.

90%

Wave rate

A flak wave spawns roughly every 2 s - timed frame-by-frame from gameplay footage and consistent across ships.

every ~2 s

Fired by

Flak keeps firing while at least one secondary battery mount is operational - even losing every other AA mount does not stop it.

Secondary battery

Flak zone

The activation band: flak fires while attacking planes are inside it. Clouds are placed ahead of the planes' path, so bursts can land short of 2.5 km or past 3.5 km - once planes get inside the band, new waves stop. AA range bonuses push the outer edge out; the 2.5 km inner edge does not move.

Crash stop

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. Same community-model simulation as the acceleration times, using the ship's own reverse-power ratio from in-game data. The full curve is on the acceleration chart.

22.5 s

Engine boost threshold (reverse)

Acceleration 0-90%

Time to reach 90% of top speed (31.9 kt of 35.5 kt), from our in-house acceleration model.

23.3 s

Acceleration 0-99%

Time to reach 99% of top speed (35.1 kt of 35.5 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.

37.1 s

Traverse-to-turn ratio

How many degrees the turret can swing for each degree the hull turns. Turn rate

ω_{hull} = \frac{180}{π} \cdot \frac{V_{max} (m/s)}{R_{turn}} = \frac{180}{π} \cdot \frac{35.5 \cdot 0.5144}{850} = 1.23 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{7}{1.23} = 5.7 \times

How wide your shells scatter at 10 km, from the same dispersion model as the max-range figure above. Picking a fixed range makes this number directly comparable from ship to ship: max-range dispersion makes a longer-range gun look worse even when it's tighter at any common range. The interactive Dispersion tab on the Charts card plots the full curve from 0 to max range.

Max Vert Disp78 m at 14.1 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 129.9 \cdot 0.6 = 78 m$

Shell scatter height @ 10 km55.3 m

How tall the same scatter ellipse is at 10 km. Comparable from ship to ship for the same reason as the width value above. The height/width ratio is a piecewise-linear curve through three points from the ship's own dispersion data:  $radiusOnZero = 0.2$  at 0 m,  $radiusOnDelim = 0.5$  at  $delim \cdot R_{m a x} = 0.5 \cdot 14050.3 = 7025$  m, and  $radiusOnMax = 0.6$  at 14050.3 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7025}{14050.3 - 7025} = 0.5423$ , so  $σ_{V} = σ_{H} \cdot k = 102 \cdot 0.5423 = 55.3 m$ .

Med Horiz Disp39 m at 14.1 km

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 129.9 \cdot \frac{0.6}{2} = 39 m$

Med Vert Disp23.4 m at 14.1 km

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 78 \cdot \frac{0.6}{2} = 23.4 m$

AP Pen Close303.2 mm point-blank

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2300 \cdot {51.5}^{0.69} \cdot {0.152}^{- 1.07} \cdot 880^{1.38} = 303.2 mm$ . Matches the in-game spec card.

AP Pen Far114.1 mm at 14.1 km

Same formula at the ship's max firing range (14.1 km), where the shell has slowed to 433.4 m/s:  $P = 10^{- 7} \cdot 2300 \cdot {51.5}^{0.69} \cdot {0.152}^{- 1.07} \cdot {433.4}^{1.38} = 114.1 mm$ .

AP pen 5 km209 mm

AP penetration at a fixed 5 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 10 km147 mm

AP penetration at a fixed 10 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

HE flight time @ 10 km5.43 s

How long an HE shell takes to reach a target at a fixed 10 km, from the same numerically integrated trajectory the Charts card plots. The shell slows under quadratic air drag,  $a_{drag} = k ρ v^{2}$ , where  $ρ$  is air density from a standard-atmosphere profile and  $k$  bundles the shell's drag coefficient, caliber and mass:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2488 \cdot {0.152}^{2}}{8 \cdot 51.5} = 4.38 \times 10^{- 5}$ . That runs from a 880 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77: the game clock runs faster than real time, and that factor was measured against stopwatch runs in the Training Room. Lower is better, since a faster shell is harder to dodge and needs less lead.

HE penetration25 mm

25 mm ≈ 152 mm caliber / 6 (standard HE penetration ratio).

AP overmatch10 mm

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

AP AOE Radius12

AP shell over-penetration splash radius; scales with shell mass. Wickes 102mm = 3, standard 152mm CL ~ 20, Iowa 406mm ~ 270, Yamato 460mm = 400, Incomparable 650mm = 550 (max). Larger value = bigger splash damage area when AP over-pens.

Torpedoes

Torpedo detectability1.3 km

Estimated torpedo reaction time7.6 s

detectability / (speed kt x 2.6855 game-speed factor, m/s per knot, calibrated from in-game measurement; the community's traditional 2.6 reads about 3% slower).

Torpedo speed64 kt

Travel time to max range23.4 s

range / (speed kt x 2.6855 game-speed factor, m/s per knot, calibrated from in-game measurement).

Torpedo module damage1,000

Per-torpedo module/blast damage parameter from in-game data. 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; the exact module-HP conversion is not published.

Tube count6

2 launchers x 3 tubes.

Per-side salvo3 torpedoes

tube count / 2 (symmetric port/starboard launcher layout; common on cruisers and battleships with deck torpedoes).

Full-salvo damage80,400

All tubes hitting one target: tubes x per-torpedo simulated damage = 6 x 13,400 = 80,400.

Per-side salvo damage40,200

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 3 x 13,400 = 40,200.

AA defense

AA DPS at max range28

Only families that reach 3.5 km contribute at the outer edge of the AA bubble. In-game families: 37mm70K 6x1 -> 82 DPS @ 3.2 km; 12 DShK 4x1 -> 39 DPS @ 1.2 km; 100mm B 34 6x1 -> 28 DPS @ 3.5 km.

Maximum AA range3.5 km

Longest-reaching family on the in-game AA card. Base AirDefense aura max range is 2.5 km; dual-purpose mount auras extend it.

AA DPS layered by range28 DPS @ 3.5 km, 110 DPS @ 3.2 km, 149 DPS @ 1.2 km

Cumulative AA DPS at each family range threshold. Inner ranges stack the outer families, so a target closing the distance hits stronger AA bubbles as it crosses each band.

AA DPS at point-blank149

Sum of every family's average DPS, achievable only inside the closest-range family (1.2 km).

AA threat index407

SUM over AA auras of (aura DPS x aura range km). A plane crossing the AA bubble is exposed to each aura for a time proportional to that aura's range, so long-reach DPS is worth more than the same DPS in a short bubble. Units: DPS*km; used to rank overall AA threat across the cohort.

Near aura range1.2 km

Secondary battery dispersion

Secondary dispersion typeStandard

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 km258 m

4 km × 57 + 30 = 258 m.

Secondary battery firepower

Secondary DPM (per side)63,000

Sum across all secondary families of (per-side barrels × 60 / reload_s × alpha), where per-side barrels = mounts × barrels-per-mount / 2 (the guns that bear on one broadside target). Per-family: 6×1 100 mm (3/side) × 60/4 × 1400 = 63,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha1400

Maximum HE damage per shell across secondary HE families. Best on this ship: 1400 from the 100 mm family.

Max HE fire chance6%

Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 6% from the 100 mm family.

Max HE pen17 mm

Maximum HE armor penetration across secondary HE families (caliber × 1/6 for most nations; 1/4 for German/UK BBs). Shells whose pen falls under a plate's armor thickness shatter for 0 hull damage though fire chance still applies. Best on this ship: 17 mm from the 100 mm family.

Armor Beta

Hull HP 22,700 → 25,700 with hull upgrade, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are the exact in-game values, not estimated.

Bow & stern16 mm

Overmatched by 76+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel50 mm

Thin belt: battleship AP citadels straight through it broadside. Rely on angle, speed and concealment, never sit flat.

An AP citadel penetration deals the shell's full damage, the biggest single hit available; only over-penetrations are damped, to ×0.10.
Superstructure	10 mm primary (range 10–150 mm)	1,300 (5% of HP)	Any HE ≥16 mm pens at full damage	Any HE ≥16 mm pens at full damage. HE-spam target, and the section saturates fast (often only a few thousand HP).

Secondary mount (100 mm mount)	separate HP pool, does not drain ship HP	800 per-mount HP	Destroyed at 0 HP	Per-mount HP for the heaviest secondary on this ship. A mount destroyed at 0 HP is out for the rest of the battle; DCP does not repair destroyed mounts. Smaller (lighter-caliber) secondaries typically share the same HP value.
AA mount (37 mm mount)	separate HP pool, does not drain ship HP	200 per-mount HP	Destroyed at 0 HP	Per-mount HP for the heaviest AA on this ship. An AA mount destroyed at 0 HP stops shooting down planes for the rest of the battle; DCP does not repair destroyed mounts. HE shells specifically target AA mounts since the small-caliber HP pool falls fast.
Rudder (module)	separate HP pool, does not drain ship HP	7,700 module HP	Incapacitated at 0 HP	When module HP reaches 0 the rudder locks at its current angle until DCP repairs it. Repair via Damage Control Party.

Saturation cap = HP a section can absorb before further damage to it is reduced (the "bow-tank" effect). Citadel pool is ~165k on every ship (effectively no cap); damage is gated by pen/over-pen multipliers instead. Superstructure saturates fast but HE always pens regardless of the plate thickness. Rudder (and other module HPs) are a separate pool from ship HP: damaging a module doesn't drain ship HP. Incapacitated modules like the rudder and engine are restored by DCP, but secondary and AA mounts destroyed at 0 HP stay out for the rest of the battle.
