Overview

AL Harbin is a Tier VII Pan-Asian light cruiser whose Smoke Generator lets her trade DPM from cover instead of from open water. The kit rewards static, sustained fire rather than rotation play. Standout traits: best extra smoke charges in T7 CAs (5) and top-decile repairs citadel hits in T7 CAs (50).

Positioning

Anchor near your smoke cycle on a contested cap and trade DPM from inside the cloud. The kit rewards a static firing position; rotating mid-smoke wastes the consumable for the next contest. 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 6.1 km, and a destroyer here is spotted at about 7 km, so you see it coming with roughly 0.89 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 4.4 km) and radar (about 9.5 km) read straight in regardless. At 600 m the screen is wider than standard, so it can cover a teammate holding the same line as well as your own hull. She is genuinely evasive in both phases of a turn, answering the helm in 7 s and carving a 660 m circle, so you can break a salvo and still be where you meant to go.

Potato Avoidance

Burning Torpedo Reload Booster on a hopeful salvo

With a single charge it is a finisher rather than an opener: spend it on a target that cannot turn away, a broadside battleship or a cruiser already committed to its own attack, where the extra torpedo salvo lands as damage instead of splashes. A booster pressed on a maybe is one you will not have when the certainty shows up.

Signature Traits

Extra smoke charges ↗

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.

36.6%

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 (3,060 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 (3,400 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.

14,800

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.

10,200

Effective HP

Base 34,000 HP plus everything Repair Party can restore: 0.6%/s x 28 s = 5,712 HP per charge, x2 charges = 11,424 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. Repair Party is one choice in its slot on this ship, so this applies only if you take it.

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 ±147°, 2x ±151°

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 = 52, 200 \cdot 0.333 = 17, 400

≈ 17,400

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.

18,600

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}{64 kt \times 2.6855} = 7.6 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.

7.6 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 3.2 per hit, shown as

3.2 \times 100 = 320 %

. 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 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 × 230 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.

Cloud damage

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

230

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 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 5.2 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.

23.9 s

Engine boost threshold (reverse)

Time to reach 90% of top speed (30.1 kt of 33.4 kt), from our in-house acceleration model.

24.2 s

Acceleration 0-99%

Time to reach 99% of top speed (33.1 kt of 33.4 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.

38.8 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{33.4 \cdot 0.5144}{660} = 1.49 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{25}{1.49} = 16.8 \times

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 132.9 \cdot 0.6 = 79.7 m$

Shell scatter height @ 10 km54.9 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  $delim \cdot R_{m a x} = 0.5 \cdot 14476 = 7238$  m, and  $radiusOnMax = 0.6$  at 14476 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7238}{14476 - 7238} = 0.5382$ , so  $σ_{V} = σ_{H} \cdot k = 102 \cdot 0.5382 = 54.9 m$ .

Med Horiz Disp38.9 m at 14.5 km

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 132.9 \cdot \frac{0.6}{2.05} = 38.9 m$

Med Vert Disp23.3 m at 14.5 km

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 79.7 \cdot \frac{0.6}{2.05} = 23.3 m$

AP Pen Close193.8 mm point-blank

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 1700 \cdot {33.5}^{0.69} \cdot {0.13}^{- 1.07} \cdot 870^{1.38} = 193.8 mm$ . Matches the in-game spec card.

AP Pen Far55.3 mm at 14.5 km

Same formula at the ship's max firing range (14.5 km), where the shell has slowed to 350.8 m/s:  $P = 10^{- 7} \cdot 1700 \cdot {33.5}^{0.69} \cdot {0.13}^{- 1.07} \cdot {350.8}^{1.38} = 55.3 mm$ .

AP pen 5 km120 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 km77 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 km5.98 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2857 \cdot {0.13}^{2}}{8 \cdot 33.5} = 5.66 \times 10^{- 5}$ . 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 flight time @ 10 km5.99 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2857 \cdot {0.13}^{2}}{8 \cdot 33.4} = 5.68 \times 10^{- 5}$ . 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 penetration22 mm

22 mm ≈ 130 mm caliber / 6 (standard HE penetration ratio).

AP overmatch9 mm

floor(130 mm caliber / 14.3) = 9 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius9

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 time7.2 s

180 degrees / 25 deg/s traverse speed = 7.2 s.

2,300 AP damage x 10 broadside guns = 23,000.

HE DPMInitial: 225,000 → 251,163

Zero upgrades: 18,000 HE full-salvo alpha x 60 / 4.8 s base reload = 225,000. All upgrades (Main Battery Mod. 3 = -10% reload): 18,000 HE full-salvo alpha x 60 / 4.3 s all-upgrades reload = 251,163.

AP DPMInitial: 287,500 → 320,930

Shells/minInitial: 125 → 139.5

Zero upgrades: 10 broadside guns x 60 / 4.8 s base reload = 125. All upgrades (Main Battery Mod. 3 = -10% reload): 10 broadside guns x 60 / 4.3 s all-upgrades reload = 139.5.

Fires/minInitial: 10 → 11.16

Zero upgrades: 125 shells/min x 8% fire chance = 10. All upgrades (Main Battery Mod. 3 = -10% reload): 139.5 shells/min x 8% fire chance = 11.16.

Torpedoes

Torpedo detectability1.3 km

Estimated torpedo reaction time7.6 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 speed64 kt

Travel time to max range63.9 s

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

Torpedo module damage1,200

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 count12

4 launchers x 3 tubes.

Per-side salvo6 torpedoes

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

Full-salvo damage208,800

All tubes hitting one target: tubes x per-torpedo simulated damage = 12 x 17,400 = 208,800.

Per-side salvo damage104,400

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 6 x 17,400 = 104,400.

AA defense

AA DPS at max range82

Only families that reach 5.2 km contribute at the outer edge of the AA bubble. In-game families: 37mm 67 V11 10x2 -> 164 DPS @ 3.5 km; 37mm 46k 4x4 -> 66 DPS @ 3.5 km; 20mm Oerlikon MK20 Twin 8x2 -> 89 DPS @ 2 km; Far AA (?) -> 82 DPS @ 5.2 km.

Maximum AA range5.2 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 range82 DPS @ 5.2 km, 312 DPS @ 3.5 km, 401 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-blank401

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

AA threat index1409

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

Armor Beta

Hull HP 34,000, 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 & stern16 mm

Overmatched by 141+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel100 mm

Thin belt: battleship AP citadels straight through it broadside. Rely on angle, speed and concealment, never sit flat.

Farming16 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 37%, fires burn 30s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	16 mm primary (range 16–40 mm)	≈ 1,700 (~5% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)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)	16 mm primary (range 16–100 mm)	≈ 25,500 (~75% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)Angle bounces 203mm16 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 16–50 mm)	≈ 1,700 (~5% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)Angle bounces 203mm16 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	100 mm primary (range 13–100 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	16 mm primary (range 16–50 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.
