Overview

Émile Bertin is a Tier IV French light cruiser with Sonar as her vision tool. Hydro lets her contest islands and smoke without exposing the hull to vision cycles, which shapes how she pressures caps. Her sonar reaches 3.7 km, which is the range at which she can commit to a contest without guessing. Standout traits: best turret traverse rate in T4 CAs (12) and best top speed in T4 CAs (39 kt).

Positioning

Sit 10-13 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.

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.

Signature Traits

Fast turret traverse ↗

12°/s turret traverse, best of T4 CAs. Tracks fast-rotating targets peers can't keep up with.

Fast for the class ↗

39 kt, best of T4 CAs. Lets you rotate flanks or escape disengagements.

AA specialist ↗

AA DPS in the top bracket. Sanctuary for friendly DDs against carriers; dangerous airspace for airstrikes.

Hull dimensions

Length x beam at the waterline, with the hull's draft where the client carries one. 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. Length matters when dodging torpedoes; beam and draft shape how hard the ship is to hit.

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 (2,385 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 (2,650 HP on this ship). Verified against measured flood ticks in replay data.

0.25% of HP per second

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.

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.

13,300

Steering gear HP

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.

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.

±147°, ±146°, ±139°

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.

Projectile speed58 kt

Range7.5 km

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 = 36, 700 \cdot 0.333 = 12, 233

≈ 12,233

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.

13,233

Torpedo detectability1.2 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{1.2 km}{58 kt \times 2.6855} = 7.7 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.

7.7 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 1.99 per hit, shown as

1.99 \times 100 = 199 %

. 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.

Bursts

Each ~2 s wave fires 2 quick salvos of 1 clouds ahead of the attacking squadron - up to 2 clouds per wave × 130 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.

130

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 4 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.

26.1 s

Engine boost threshold (reverse)

Speed below which the engine's built-in power boost applies in reverse. Matches the in-game maneuverability card's reverse threshold (Vampire II reads 10.5 here and the card shows 11; the card rounds half up).

10.4 kt

Acceleration 0-90%

Time to reach 90% of top speed (35.1 kt of 39 kt), from our in-house acceleration model.

26 s

Acceleration 0-99%

Time to reach 99% of top speed (38.6 kt of 39 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.

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{39.0 \cdot 0.5144}{670} = 1.72 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{12}{1.72} = 7.0 \times

Max Horiz Disp128.1 m at 13.8 km

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{13783}{30} \cdot \frac{8 - 1.1}{1000} + 1.1) \cdot 30 = 128.1 m$

Shell scatter width @ 5 km67.5 m

Horizontal scatter at a fixed 5 km, from the same verified dispersion model as the rows below - a knife-fight-range anchor comparable across ships.

Shell scatter width @ 10 km102 m

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 Disp76.9 m at 13.8 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 128.1 \cdot 0.6 = 76.9 m$

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  $delim \cdot R_{m a x} = 0.5 \cdot 13783 = 6892$  m, and  $radiusOnMax = 0.6$  at 13783 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 6892}{13783 - 6892} = 0.5451$ , so  $σ_{V} = σ_{H} \cdot k = 102 \cdot 0.5451 = 55.6 m$ .

Med Horiz Disp38.4 m at 13.8 km

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 128.1 \cdot \frac{0.6}{2} = 38.4 m$

Med Vert Disp23.1 m at 13.8 km

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 76.9 \cdot \frac{0.6}{2} = 23.1 m$

AP Pen Close310 mm point-blank

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2225 \cdot {57.1}^{0.69} \cdot {0.152}^{- 1.07} \cdot 870^{1.38} = 310 mm$ . Matches the in-game spec card.

AP Pen Far102.3 mm at 13.8 km

Same formula at the ship's max firing range (13.8 km), where the shell has slowed to 389.5 m/s:  $P = 10^{- 7} \cdot 2225 \cdot {57.1}^{0.69} \cdot {0.152}^{- 1.07} \cdot {389.5}^{1.38} = 102.3 mm$ .

AP pen 5 km201 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 km133 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 km5.96 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3401 \cdot {0.152}^{2}}{8 \cdot 55} = 5.61 \times 10^{- 5}$ . That runs from a 870 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.

AP flight time @ 10 km5.77 s

How long an AP 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3226 \cdot {0.152}^{2}}{8 \cdot 57.1} = 5.13 \times 10^{- 5}$ . That runs from a 870 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 Radius15

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.

Broadside guns used for alpha9

All 9 barrels bear on the broadside.

Turret turn time15 s

180 degrees / 12 deg/s traverse speed = 15 s.

HE full-salvo alpha19,800

2,200 HE damage x 9 broadside guns = 19,800.

AP full-salvo alpha27,900

3,100 AP damage x 9 broadside guns = 27,900.

HE DPM99,000

19,800 HE full-salvo alpha x 60 / 12 s base reload = 99,000.

AP DPM139,500

27,900 AP full-salvo alpha x 60 / 12 s base reload = 139,500.

Shells/min45

9 broadside guns x 60 / 12 s base reload = 45.

Fires/min4.5

45 shells/min x 10% fire chance = 4.5.

Torpedoes

Torpedo detectability1.2 km

Estimated torpedo reaction time7.7 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 speed58 kt

Travel time to max range48.2 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 damage73,398

All tubes hitting one target: tubes x per-torpedo simulated damage = 6 x 12,233 = 73,398.

Per-side salvo damage36,699

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 3 x 12,233 = 36,699.

AA defense

AA DPS at max range6

Only families that reach 4 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors Mk2 2x4 -> 55 DPS @ 3.5 km; 40mm Bofors Mk1 2x2 -> 55 DPS @ 3.5 km; 20mm Oerlikon MK4 14x1 -> 113 DPS @ 2 km; 90mm 50 Mle 1926 2x1 -> 6 DPS @ 4 km.

Maximum AA range4 km

Longest-reaching family on the in-game AA card. Base AirDefense aura max range is 3 km; dual-purpose mount auras extend it.

AA DPS layered by range6 DPS @ 4 km, 116 DPS @ 3.5 km, 229 DPS @ 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-blank229

Sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index635

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 range2 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)39,000

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: 1×2 90 mm (1/side) × 60/4 × 1300 = 19,500 + 2×1 90 mm (1/side) × 60/4 × 1300 = 19,500. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha1300

Maximum HE damage per shell across secondary HE families. Best on this ship: 1300 from the 90 mm family.

Max HE fire chance5%

Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 5% from the 90 mm family.

Max HE pen15 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: 15 mm from the 90 mm family.

Armor Beta

Hull HP 21,100 → 26,500 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 & stern13 mm

Overmatched by 89+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Farming6 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 17%, fires burn 30s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	13 mm primary (range 13–30 mm)	3,600 (14% of HP)	Overmatched by 203mm+ AP (Desert Falcon, Baleares)Angle bounces 152mm13 mm: HE pens from 127mm+	Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.
Stern	13 mm primary (range 13–30 mm)	1,500 (6% of HP)	Overmatched by 203mm+ AP (Desert Falcon, Baleares)Angle bounces 152mm13 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	30 mm primary (range 10–30 mm)	≈ 165,500 (effectively no cap)	Citadel pen: full damageOver-pen: ×0.10 damage	Effectively no cap; citadel pool sits at ~165k HP on every ship. An AP citadel penetration deals the shell's full damage, the biggest single hit available; only over-penetrations are damped, to ×0.10.
Superstructure	6 mm primary (range 6–20 mm)	1,400 (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).
Turret (module, per magazine)	separate HP pool, does not drain ship HP	13,300 magazine HP	Turret knocked out	Per-turret powder-magazine HP, a separate pool that does not drain ship HP. As it is worn down the turret is likelier to be knocked out, and a smaller pool gets there faster.
Secondary mount (90 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 (40 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	8,000 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.
