Pre-release

Roussillon is in the World of Warships: Legends client but has not been officially released yet. The stats on this page come from the current in-game data and may still change before launch.

Playstyle

Overview

Roussillon is a French Tier VIII premium battleship that fights at the long end of her range and punishes anyone who closes. Her nine 406 mm guns reach 17,450 m (8th of 33) and her AP shells travel at 850 m/s (6th of 33), so they arrive fast and predictably. Her real damage engine is fire: a 49 percent HE fire chance, the best of 31. The trade is a 69,000 HP pool at 30th of 33 and a 32.4 second reload at 31st, so she is armoured rather than durable and every salvo has to count.

Positioning

Fight at the long end of her range, angled, so the guns keep working without showing broadside. Thick armour, 430 mm at its heaviest (7th of 33), is what makes holding that angle pay. If a ship does close, her secondaries reach 7,500 m, tied for the longest at her tier, with a 12 percent fire chance (3rd of 31), so the approach costs the attacker. They scatter, though: 457.5 m dispersion, 33rd of 33, so treat them as a deterrent rather than a damage plan. Handling is ordinary, so choose the angle early rather than correcting under fire.

Potato Avoidance

Torpedo Boat Brawling

With no torpedoes you cannot trade back inside enemy torpedo range. This hull is the worst one to try it with anyway: a 69,000 HP pool at 30th of 33 and a 32.4 second reload at 31st mean a knife fight is the exchange she cannot win, however thick the armour looks. Her secondaries invite it, reaching 7,500 m, but they scatter more than any in the cohort (457.5 m, 33rd of 33), so treat them as a deterrent rather than a reason to close. Hold the long band where the mains and a 49 percent fire chance, the best of 31, do the work.

No torpedo backup

A brawler with no torpedoes: every trade is guns and secondaries. The sweet spot is inside secondary range but outside easy torpedo range -- close enough that the auto-fire battery works, not so close that a destroyer or torpedo cruiser lands a salvo you can't answer.

Acquisition

How to get Roussillon

Roussillon is a Premium ship and not available to unlock in the Tech Tree. Acquisition path: Premium/Event.

Premium/EventAvailability usually depends on store rotations, event reruns, collaborations, coupons, or special offers.

Builds

Reload and survivability outrank accuracy. Anything shortening a 32.4 second reload compounds all match, so accuracy investment returns less than it looks. With the longest secondary reach at her tier and the best HE fire chance, secondary and fire-chance builds have unusually good material here. Check current picks in the Build Tool before committing points.

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.

40%

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 (12,420 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 (13,800 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.

44%

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.

20,700

Effective HP

Base 69,000 HP plus everything Repair Party can restore: 0.5%/s x 28 s = 9,660 HP per charge, x3 charges = 28,980 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, and 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.

2x ±150°, ±145°

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 × 210 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.

75%

Wave rate

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

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.

2.5-5 km

Bursts

Each ~2 s wave fires 2 quick salvos of 3 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between waves - up to 7 clouds per wave × 210 damage each.

12.9 kt

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.

41.6 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).

9 kt

Acceleration 0-90%

Time to reach 90% of top speed (28.8 kt of 32 kt), from our in-house acceleration model.

35.3 s

Acceleration 0-99%

Time to reach 99% of top speed (31.7 kt of 32 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.

56.5 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{32.0 \cdot 0.5144}{910} = 1.04 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{7}{1.04} = 6.8 \times

Shell Grouping (σ)1.7

Max Horiz Disp194.6 m at 17.4 km

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{17450}{30} \cdot \frac{10 - 1.6}{1000} + 1.6) \cdot 30 = 194.6 m$

Shell scatter width @ 5 km90 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 km132 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.

Shell scatter width @ 15 km174 m

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.

Max Vert Disp116.7 m at 17.4 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 194.6 \cdot 0.6 = 116.7 m$

Shell scatter height @ 10 km67.9 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  $delim \cdot R_{m a x} = 0.5 \cdot 17450 = 8725$  m, and  $radiusOnMax = 0.6$  at 17450 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 8725}{17450 - 8725} = 0.5146$ , so  $σ_{V} = σ_{H} \cdot k = 132 \cdot 0.5146 = 67.9 m$ .

Med Horiz Disp68.7 m at 17.4 km

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 194.6 \cdot \frac{0.6}{1.7} = 68.7 m$

Med Vert Disp41.2 m at 17.4 km

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 116.7 \cdot \frac{0.6}{1.7} = 41.2 m$

AP Pen Close916.9 mm point-blank

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2900 \cdot 900^{0.69} \cdot {0.406}^{- 1.07} \cdot 850^{1.38} = 916.9 mm$ . Matches the in-game spec card.

AP Pen Far588.8 mm at 17.4 km

Same formula at the ship's max firing range (17.4 km), where the shell has slowed to 616.7 m/s:  $P = 10^{- 7} \cdot 2900 \cdot 900^{0.69} \cdot {0.406}^{- 1.07} \cdot {616.7}^{1.38} = 588.8 mm$ .

HE flight time @ 10 km4.7 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2218 \cdot {0.406}^{2}}{8 \cdot 900} = 1.6 \times 10^{- 5}$ . That runs from a 850 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 penetration68 mm

68 mm ≈ 406 mm caliber / 6 (standard HE penetration ratio).

AP overmatch28 mm

floor(406 mm caliber / 14.3) = 28 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius275

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.

AA defense

AA DPS at max range95

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 37 50 ACAD 16x2 -> 247 DPS @ 3.5 km; 25mm Hotchkiss Mle 1940 10x2 -> 81 DPS @ 3.1 km; 152 55 Mle 1936 3x3 -> 21 DPS @ 5 km; 100mm 45 Mle 1933 12x2 -> 74 DPS @ 5 km.

Maximum AA range5 km

Longest-reaching family on the in-game AA card. Base AirDefense aura max range is 3.5 km; dual-purpose mount auras extend it.

AA DPS layered by range95 DPS @ 5 km, 342 DPS @ 3.5 km, 423 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-blank423

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

AA threat index1591

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 @ 7.5 km457.5 m

7.5 km × 57 + 30 = 457.5 m.

Secondary dispersion @ 5 km315 m

Same per-type line evaluated at a fixed 5 km: 5 km × 57 + 30 = 315 m.

Secondary battery firepower

Secondary DPM (per side)301,500

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: 12×2 100 mm (12/side) × 60/4 × 1400 = 252,000 + 3×3 152 mm (4.5/side) × 60/12 × 2200 = 49,500. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha2200

Maximum HE damage per shell across secondary HE families. Best on this ship: 2200 from the 152 mm family.

Max HE fire chance12%

Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 12% from the 152 mm family.

Max HE pen25 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: 25 mm from the 152 mm family.

Armor Beta

Hull HP 69,000, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are estimated from the standard WoWs damage-allocation model.

Bow & stern32 mm

Overmatched by 7 AP guns here: Incomparable SE 25IncomparableYamato and 4 more. Angling still helps against the rest.

Belt / citadel350 mm

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

Farming19 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 40%, fires burn 60s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	32 mm primary (range 32–50 mm)	≈ 3,450 (~5% of HP)	Overmatched by 460mm+ AP (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+	Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.
Hull (midship)	405 mm primary (range 20–405 mm)	≈ 51,750 (~75% of HP)	No common AP caliber overmatches405 mm: no common HE pens	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	32 mm primary (range 32–150 mm)	≈ 3,450 (~5% of HP)	Overmatched by 460mm+ AP (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+	Mirror of bow. Same fast saturation.
Citadel	350 mm primary (range 20–350 mm)	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	19 mm primary (range 19–430 mm)	no cap	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).

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.
