Overview

Rooke is a Tier VI British fast battleship at 31.9 kn with Engine Boost on the consumable slot. Mobility lets her rotate flanks battleship-fast and pick fights where her guns get the first salvo. Standout traits: best torpedo alpha in T6 BBs (14,767) and best module-wrecking torpedoes in T6 BBs (1,100).

Positioning

Anchor a flank at 12-15 km with bow toward the closest threat, then use the speed advantage at 31.9 kn to rotate to the cap that needs a second battleship rather than the one your team already has. Mobility means you can pick which fight you are in; do not waste it by holding center the whole match. A 950 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

Using the 31.9-kn speed to push rather than to rotate

The mobility advantage is about picking which cap fight you arrive at, not about leading the brawl line; a fast BB that overextends loses HP that the kit cannot trade back.

Signature Traits

Engine Boost

+8% speed (about +2.6 kt), 120 s duration. Engine Boost consumable gives a small speed nudge - useful for closing a gap or steadying a torpedo run, not for running anything down. Uncommon in T6 BBs.

ELITE TORPEDOES ↗

Heavy torpedoes · 14767 damage
Module-wrecking torpedoes · 1100 torpedo

Hardened superstructure ↗

26 mm superstructure, best of T6 BBs. HE farms less.

ELITE MAIN BATTERY ↗

Fast turret traverse · 6°
Tight pattern at max range · 180.8 m

Quick acceleration ↗

~21.4 s to 90% of top speed, top decile of T6 BBs. Rebuilds speed quickly after a turn or stop, and sustains acceleration through the mid-range.

Thin end plates

16 mm bow and stern plating, both in the bottom bracket of T6 BBs. AP above 96 mm of caliber cannot arm on 16 mm at flat impact and overpenetrates for minimal damage; angling adds effective thickness and can push those same shells over the arming threshold, turning overpens into full penetrations; 234 mm AP and up overmatches it at any angle.

Acquisition

How to get Rooke

Rooke is available in the Pursuit Battlecruisers branch of the U.K. Tech Tree for 9,000,000 credits after researching it in the branch. Known module upgrades cost up to 2,250,000 credits.

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: 26.6% → 30%

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 (10,656 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 (11,840 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.

13%

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.

29,600

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.

17,800

Effective HP

Base 59,200 HP plus everything Repair Party can restore: 0.5%/s x 28 s = 8,288 HP per charge, x3 charges = 24,864 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.

2x ±152°, ±150°

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.

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 = 44, 300 \cdot 0.333 = 14, 767

≈ 14,767

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.

15,867

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}{61 kt \times 2.6855} = 7.9 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.

7.9 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 2.65 per hit, shown as

2.65 \times 100 = 265 %

. 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 2 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between waves - up to 5 clouds per wave × 180 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 × 2 clouds + 1 outer

Cloud damage

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

180

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 3.5 km or past 5 km - once planes get inside the band, new waves stop. AA range bonuses push the outer edge out; the 3.5 km inner edge does not move.

Reverse speed

top speed / 4 + 4.9 = 31.9 / 4 + 4.9 = 12.9 kt. The community reverse-speed model from the WoWs ShipBuilder project, the same source as the acceleration model on this card. Base value; speed modifiers scale it. Not shown on the in-game card.

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.

34.7 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).

9.6 kt

Acceleration 0-90%

Time to reach 90% of top speed (28.7 kt of 31.9 kt), from our in-house acceleration model.

21.4 s

Acceleration 0-99%

Time to reach 99% of top speed (31.6 kt of 31.9 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.

43.1 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{31.9 \cdot 0.5144}{950} = 0.99 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{5.5}{0.99} = 5.6 \times

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

Main battery formulas

Shell Grouping (σ)1.6

Max Horiz Disp180.8 m at 15.8 km

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{15813.6}{30} \cdot \frac{10 - 1.6}{1000} + 1.6) \cdot 30 = 180.8 m$

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 Disp108.5 m at 15.8 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 180.8 \cdot 0.6 = 108.5 m$

Shell scatter height @ 10 km69.5 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  $delim \cdot R_{m a x} = 0.5 \cdot 15813.6 = 7907$  m, and  $radiusOnMax = 0.6$  at 15813.6 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7907}{15813.6 - 7907} = 0.5265$ , so  $σ_{V} = σ_{H} \cdot k = 132 \cdot 0.5265 = 69.5 m$ .

Med Horiz Disp67.8 m at 15.8 km

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 180.8 \cdot \frac{0.6}{1.6} = 67.8 m$

Med Vert Disp40.7 m at 15.8 km

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 108.5 \cdot \frac{0.6}{1.6} = 40.7 m$

Dispersion familyBC Disp.

Battlecruiser dispersion. The standard mid-tier reference family that Georgia, Stalingrad, and Siegfried are compared against.

AP Pen Close722.1 mm point-blank

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2350 \cdot 809^{0.69} \cdot {0.381}^{- 1.07} \cdot 836^{1.38} = 722.1 mm$ . Matches the in-game spec card.

AP Pen Far416.2 mm at 15.8 km

Same formula at the ship's max firing range (15.8 km), where the shell has slowed to 560.8 m/s:  $P = 10^{- 7} \cdot 2350 \cdot 809^{0.69} \cdot {0.381}^{- 1.07} \cdot {560.8}^{1.38} = 416.2 mm$ .

AP pen 5 km601 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 km503 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.

AP pen 15 km427 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.

HE flight time @ 10 km4.96 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3379 \cdot {0.381}^{2}}{8 \cdot 879} = 2.19 \times 10^{- 5}$ . That runs from a 836 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 km4.96 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.31 \cdot {0.381}^{2}}{8 \cdot 809} = 2.18 \times 10^{- 5}$ . That runs from a 836 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 penetration64 mm

64 mm ≈ 381 mm caliber / 6 (standard HE penetration ratio).

AP overmatch26 mm

floor(381 mm caliber / 14.3) = 26 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius90

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.

Shells/minInitial: 15.9 → 17.4

Zero upgrades: 9 broadside guns x 60 / 34 s base reload = 15.9. All upgrades (top gun): 9 broadside guns x 60 / 31 s all-upgrades reload = 17.4.

Fires/minInitial: 5.4 → 5.92

Zero upgrades: 15.9 shells/min x 34% fire chance = 5.4. All upgrades (top gun): 17.4 shells/min x 34% fire chance = 5.92.

Torpedoes

Torpedo detectability1.3 km

Estimated torpedo reaction time7.9 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 speed61 kt

Travel time to max range48.9 s

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

Torpedo module damage1,100

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 count4

4 launchers x 1 tubes.

Per-side salvo2 torpedoes

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

Full-salvo damage59,068

All tubes hitting one target: tubes x per-torpedo simulated damage = 4 x 14,767 = 59,068.

Per-side salvo damage29,534

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 2 x 14,767 = 29,534.

AA defense

AA DPS at max range50

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 2 pdr MkVII Quad 4x4 -> 93 DPS @ 2.5 km; 2 pdr MkVIII 8barrel 4x8 -> 93 DPS @ 2.5 km; 2 pdr MkVIII 8barrel 2x8 -> 47 DPS @ 2.5 km; 20mm Oerlikon MK4 8x1 -> 58 DPS @ 2 km; 20mm Oerlikon MK V 16x2 -> 116 DPS @ 2 km; 20mm Oerlikon MK4 8x1 -> 58 DPS @ 2 km; 114mm 45 MKIII 6x2 -> 50 DPS @ 5 km.

Maximum AA range5 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 range50 DPS @ 5 km, 283 DPS @ 2.5 km, 515 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-blank515

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

AA threat index1296

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 @ 5 km315 m

5 km × 57 + 30 = 315 m.

Secondary battery firepower

Secondary DPM (per side)208,400

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: 6×2 114 mm (6/side) × 60/5 × 1700 = 122,400 + 8×2 152 mm (8/side) × 60/12 × 2150 = 86,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha2150

Maximum HE damage per shell across secondary HE families. Best on this ship: 2150 from the 152 mm family.

Max HE fire chance9%

Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 9% 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 52,600 → 59,200 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 125+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel305 mm

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

Farming16 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 30%, fires burn 60s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic

Citadel	305 mm primary (range 26–305 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	26 mm primary (range 26–254 mm)	4,800 (8% of HP)	Any HE ≥16 mm pens at full damageDamage multiplier ×0.6	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	29,600 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 (152 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	17,800 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.
