Overview

Akatsuki is a Tier VI Japanese torpedo destroyer. The kit is torpedo spam rather than gun trades: put fish into lanes the enemy has to cross and let the guns fill the gaps between reloads. Smoke plus 10 km of reach on a 76 s reload lets her launch from a position the target cannot see. Standout traits: best AA reach in T6 DDs (5 km) and top-decile flat arc HE shells in T6 DDs (915).

Positioning

Sit at the edge of a contested cap from concealment and cycle torpedo waves into lanes the enemy has to use. The 10 km reach lets you seed those lanes early, but these fish are spotted well out and give a target about 10.8 s of warning, so they earn their damage by denying space and forcing turns rather than by catching anyone unaware. Aim where a ship must go, not where it is, and stay unspotted between waves. Your guns lose penetration at range, so aim AP at broadsides you can still citadel and put HE into superstructures and upper-hull sections, rather than the bow-in or belt armor your shells bounce and shatter on. Shooting from the cloud gives you away at 2.5 km, and a destroyer here is spotted at about 6.9 km, so you see it coming with roughly 4.4 km to spare. Vision is mutual: past the 2 km guaranteed ring you cannot see out either, and nothing in her kit sees through it, so pop the smoke where someone is already lighting the enemy or you will sit in it with nothing to shoot. Enemy sonar (about 4.2 km) and radar (about 9 km) read straight in regardless.

Potato Avoidance

Holding 10-km torpedoes for a perfect shot

The kit pays out by saturating lanes, not by waiting for guaranteed broadsides; missed waves still force rotations and protect your team's flank. Idle torpedo tubes are the worst output state.

Signature Traits

Engine Boost

+8% speed (about +3 kt), 120 s duration. Engine Boost consumable lifts top speed enough to open or close a gap deliberately, though not to outrun a committed chase.

Long-reach AA ↗

5 km AA reach, best of T6 DDs.

ELITE MAIN BATTERY ↗

Flat arc HE shells · 915 m
Flat AP shells · 915 m

Slow reload ↗

7.5 s reload, bottom decile of T6 DDs. Salvos punish more, but cycle is slower than peers.

Visible torps ↗

1.8 km torpedo detect, bottom decile of T6 DDs. Spotted early, so targets get a long look and room to turn out.

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: 26.6% → 30%

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 (1,179 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 (1,310 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.

6,600

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.

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 ±145°, ±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.

Torpedoes

ModuleTorpedoes: Type90 mod. 1

Launchers / tubes3 launchers × 3 tubes = 9 tubes

Reload time

Base reload of the top torpedo module (all-upgrades configuration); the stock module reloads in 70 s. In-game port tooltips additionally fold in your installed modernizations and commander effects - e.g. Torpedo Launchers Mod. 3 alone is x0.85:

76 \times 0.85 = 64.6

76 s

Projectile speed

Speed of the top torpedo module (all-upgrades configuration, 62 kt); the stock torpedo module runs 59 kt. Site stats assume the full-upgrades fit unless a row shows a stock → top pair.

62 kt

Range9.99 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 = 46, 800 \cdot 0.333 = 15, 600

≈ 15,600

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.

16,900

Torpedo detectability1.8 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{1.8 km}{62 kt \times 2.6855} = 10.8 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.

10.8 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 2.87 per hit, shown as

2.87 \times 100 = 287 %

. 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 × 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

Every potential cloud spawns - the full pattern, every wave. Often called flak 'hit chance', but spawned clouds always damage planes that fly into them - the roll is on spawning.

100%

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 main battery mount is operational - even losing every other AA mount does not stop it.

Main 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.

Reverse speed

top speed / 4 + 4.9 = 38 / 4 + 4.9 = 14.4 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.

14.4 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.

14.3 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).

10.2 kt

Acceleration 0-90%

Time to reach 90% of top speed (34.2 kt of 38 kt), from our in-house acceleration model.

16.9 s

Acceleration 0-99%

Time to reach 99% of top speed (37.6 kt of 38 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.

28.7 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{38.0 \cdot 0.5144}{640} = 1.75 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{11}{1.75} = 6.3 \times

Shell Grouping (σ)2

Max Horiz Disp92.9 m at 10.4 km

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{10380.7}{30} \cdot \frac{8 - 0.5}{1000} + 0.5) \cdot 30 = 92.9 m$

Shell scatter width @ 5 km52.5 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 km90 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 Disp55.7 m at 10.4 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 92.9 \cdot 0.6 = 55.7 m$

Shell scatter height @ 10 km53.3 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  $delim \cdot R_{m a x} = 0.5 \cdot 10380.7 = 5190$  m, and  $radiusOnMax = 0.6$  at 10380.7 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 5190}{10380.7 - 5190} = 0.5927$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5927 = 53.3 m$ .

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2266 \cdot 23^{0.69} \cdot {0.127}^{- 1.07} \cdot 915^{1.38} = 219 mm$ . Matches the in-game spec card.

AP Pen Far47.9 mm at 10.4 km

Same formula at the ship's max firing range (10.4 km), where the shell has slowed to 304.2 m/s:  $P = 10^{- 7} \cdot 2266 \cdot 23^{0.69} \cdot {0.127}^{- 1.07} \cdot {304.2}^{1.38} = 47.9 mm$ .

AP pen 5 km101 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 km50 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 flight time @ 10 km7.25 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.334 \cdot {0.127}^{2}}{8 \cdot 23} = 9.2 \times 10^{- 5}$ . That runs from a 915 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 km7.25 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.334 \cdot {0.127}^{2}}{8 \cdot 23} = 9.2 \times 10^{- 5}$ . That runs from a 915 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 penetration21 mm

21 mm ≈ 127 mm caliber / 6 (standard HE penetration ratio).

AP overmatch8 mm

floor(127 mm caliber / 14.3) = 8 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius10

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.

All 6 barrels bear on the broadside.

Turret turn time16.4 s

180 degrees / 11 deg/s traverse speed = 16.4 s.

HE full-salvo alpha10,800

1,800 HE damage x 6 broadside guns = 10,800.

AP full-salvo alpha13,200

2,200 AP damage x 6 broadside guns = 13,200.

HE DPM86,400

10,800 HE full-salvo alpha x 60 / 7.5 s base reload = 86,400.

AP DPM105,600

13,200 AP full-salvo alpha x 60 / 7.5 s base reload = 105,600.

Shells/min48

6 broadside guns x 60 / 7.5 s base reload = 48.

Fires/min3.36

48 shells/min x 7% fire chance = 3.36.

Torpedoes

Torpedo detectability1.8 km

Estimated torpedo reaction time10.8 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 speed62 kt

Travel time to max range60 s

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

Torpedo module damage1,300

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 count9

3 launchers x 3 tubes.

Per-side salvo9 torpedoes

9 (centerline launchers train across - full salvo to either side).

Full-salvo damage140,400

All tubes hitting one target: tubes x per-torpedo simulated damage = 9 x 15,600 = 140,400.

Per-side salvo damage140,400

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 9 x 15,600 = 140,400.

AA defense

AA DPS at max range53

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 25mm Type96 4x3 -> 46 DPS @ 3.1 km; 25mm Type96 single 2x1 -> 23 DPS @ 3.1 km; 25mm Type96 double 1x2 -> 12 DPS @ 3.1 km; Far AA (?) -> 53 DPS @ 5 km.

Maximum AA range5 km

Longest-reaching family on the in-game AA card. Base AirDefense aura max range is 3.1 km; dual-purpose mount auras extend it.

AA DPS layered by range53 DPS @ 5 km, 134 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-blank134

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

AA threat index516

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.

Armor Beta

Hull HP 11,600 → 13,100 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.

Farming6 mm

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

Section	Plates	HP cap	Threats	Tactic
Bow	16 mm primary (range 15–16 mm)	1,800 (14% of HP)	Overmatched by 283mm+ AP (Graf Spee, Scharnhorst)Angle bounces 203mm16 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)	15 mm	9,800 (75% of HP)	Overmatched by 283mm+ AP (Graf Spee, Scharnhorst)Angle bounces 203mm15 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	16 mm primary (range 15–16 mm)	1,300 (10% of HP)	Overmatched by 283mm+ AP (Graf Spee, Scharnhorst)Angle bounces 203mm16 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	16 mm primary (range 6–16 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	800 (6% 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	6,600 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.
AA mount (25 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	3,900 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.
