Overview

Bretagne is a Tier IV French all-rounder battleship with 340mm guns at 15.3 km: she has no single dominant kit trait but is competent across the board. The role flexes by team comp - mid-range AP anchor by default, brawl support when the team commits, sniper when the line sits back. Versatility is the value, not specialization. Standout traits: best flat arc HE shells in T4 BBs (921) and best AA reach in T4 BBs (5 km).

Positioning

Sit 12-15 km from the brawl line and exploit the range advantage. You do not need to push into peer fire to land damage; rotate one or two map cells back if a flank starts to collapse. Once the rudder is over she turns tightly for her cohort (580 m), so a committed turn costs less water than most of what she is fighting.

Potato Avoidance

Treating her like a fast battleship because of the line name

Despite the Fast Battleships line she is slow for her tier (21 kn), so she cannot reposition or slip focus fire the way her faster line-mates can. Pick your lane early, angle hard, and trade from a spot you can hold rather than expecting to escape on speed.

Signature Traits

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 duration60 s

Fire damage

Each fire ticks 0.3% of max HP per second for the full 60 s, so one unattended fire burns 18% of the pool (7,506 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 0.5% of max HP per second for the 40 s duration, so one unattended flood costs 20% of the pool (8,340 HP on this ship). Verified against measured flood ticks in replay data.

0.5% 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.

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.

20,900

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.

12,500

Effective HP

Base 41,700 HP plus everything Repair Party can restore: 0.5%/s x 28 s = 5,838 HP per charge, x3 charges = 17,514 HP. Ceiling, not a prediction: a charge only restores damage actually taken, and only the regeneratable share of it. Across 1,826 players in our replay corpus the median ship realized about half of this, mostly because half the charges go unspent — when Repair Party IS pressed it returns ~97% of the per-charge figure above.

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.

3x ±142°, ±139°, ±140°

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.

Bursts

Each ~2 s wave fires 2 quick salvos of 1 clouds ahead of the attacking squadron - up to 2 clouds per wave × 150 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.

150

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.

75%

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 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.

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.

Time to reach 90% of top speed (18.9 kt of 21 kt), from our in-house acceleration model.

36.3 s

Acceleration 0-99%

Time to reach 99% of top speed (20.8 kt of 21 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.

60.1 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{21.0 \cdot 0.5144}{580} = 1.07 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{3}{1.07} = 2.8 \times

. Below 5 the turrets drag in a turning fight; 25+ keeps up with any rudder.

Shell scatter width @ 5 km115 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 km164 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.

Horizontal scatter at a fixed 15 km, from the same verified dispersion model - the long-range anchor. Only shown when the ship's guns reach 15 km.

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 216.3 \cdot 0.6 = 129.8 m$

Shell scatter height @ 10 km87 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  $delim \cdot R_{m a x} = 0.5 \cdot 15336.2 = 7668$  m, and  $radiusOnMax = 0.6$  at 15336.2 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7668}{15336.2 - 7668} = 0.5304$ , so  $σ_{V} = σ_{H} \cdot k = 164 \cdot 0.5304 = 87 m$ .

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.

AP pen 15 km285 mm

AP penetration at a fixed 15 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 flight time @ 10 km5.65 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.4009 \cdot {0.34}^{2}}{8 \cdot 585} = 3.11 \times 10^{- 5}$ . That runs from a 780 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 flight time @ 10 km5.13 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.4009 \cdot {0.34}^{2}}{8 \cdot 431.8} = 4.21 \times 10^{- 5}$ . That runs from a 921 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 penetration57 mm

57 mm ≈ 340 mm caliber / 6 (standard HE penetration ratio).

AP overmatch23 mm

floor(340 mm caliber / 14.3) = 23 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius50

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 alpha10

All 10 barrels bear on the broadside.

Turret turn time60 s

180 degrees / 3 deg/s traverse speed = 60 s.

HE full-salvo alpha47,000

4,700 HE damage x 10 broadside guns = 47,000.

AP full-salvo alpha95,000

9,500 AP damage x 10 broadside guns = 95,000.

HE DPM94,000

47,000 HE full-salvo alpha x 60 / 30 s base reload = 94,000.

AP DPM190,000

95,000 AP full-salvo alpha x 60 / 30 s base reload = 190,000.

Shells/min20

10 broadside guns x 60 / 30 s base reload = 20.

Fires/min5.2

20 shells/min x 26% fire chance = 5.2.

AA defense

AA DPS at max range29

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors Mk3 8x1 -> 92 DPS @ 3.5 km; 25mm Hotchkiss Mle 1940 8x2 -> 76 DPS @ 3.1 km; 100mm 45 Mle 1930 4x2 -> 29 DPS @ 5 km.

Maximum AA range5 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 range29 DPS @ 5 km, 121 DPS @ 3.5 km, 197 DPS @ 3.1 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-blank197

Sum of every family's average DPS, achievable only inside the closest-range family (3.1 km).

AA threat index703

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 range3.1 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)132,000

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: 22×1 139 mm (11/side) × 60/10 × 2000 = 132,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha2000

Maximum HE damage per shell across secondary HE families. Best on this ship: 2000 from the 139 mm family.

Max HE fire chance8%

Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 8% from the 139 mm family.

Max HE pen23 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: 23 mm from the 139 mm family.

Armor Beta

Hull HP 38,300 → 41,700 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 & stern19 mm

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

Belt / citadel250 mm

Citadels come from a flat broadside at close range; held past ~30° of angle, AP shatters or bounces.

Farming13 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 17%, fires burn 60s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	19 mm primary (range 19–200 mm)	1,200 (3% of HP)	Overmatched by 283mm+ AP (Nassau, Von Der Tann)Angle bounces 203mm19 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.
Hull (midship)	270 mm primary (range 10–270 mm)	31,300 (75% of HP)	No common AP caliber overmatches270 mm: no common HE pens	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	19 mm primary (range 19–200 mm)	1,600 (4% of HP)	Overmatched by 283mm+ AP (Nassau, Von Der Tann)Angle bounces 203mm19 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	250 mm primary (range 13–250 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	13 mm primary (range 13–300 mm)	1,400 (3% 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	20,900 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 (139 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.
Engine (module, research)	engine coefficient (unconfirmed)	-0.050 research estimate	Largest on BB/BC; zero on destroyers	Engine durability isn't a per-ship value in the game data. This small negative coefficient is non-zero only on battleships, battlecruisers, and the heaviest cruisers, and is exactly zero on every destroyer, so it scales with hull displacement rather than any commander skill. Most likely an engine drag or power term in the same family as the deceleration stats; its exact meaning is not yet confirmed.
Rudder (module)	separate HP pool, does not drain ship HP	12,500 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.
