Overview

Haida is a Tier VII Commonwealth gunboat destroyer: her damage comes from sustained main battery pressure on caps and open-water trades. Torpedoes are a secondary threat for closing lanes, not her main damage. Her 120mm guns win on volume rather than weight: a 4 s reload is the damage, so uptime matters more than any single salvo. Standout traits: best smoke duration in T7 DDs (100 s) and best Sonar duration in T7 DDs (180 s).

Positioning

Hold mid-cap distance and lean into gunboat trades from cover where the peer destroyer cannot match your fires-per-minute. Avoid open-water duels with ships running smoke or radar; the torpedoes are a closer, not the plan, so gunfire from cover wins more than from blue water. Concretely: 10.9 km of reach against 6.6 km of detection leaves about 4.3 km in which you can shoot before the answer arrives. 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.

Potato Avoidance

Trading guns in open water against peer DDs

Your damage is sustained main-battery pressure from cover (the torpedoes are a secondary threat), so open-water duels just stack incoming HE on you while you fire back. You are visible from 6.6 km with 18,500 HP to spend, so the second ship to join the trade decides it.

Signature Traits

Engine Boost

+8% speed (about +2.9 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.

Thin end plates

16 mm bow and stern plating, both in the bottom bracket of T7 DDs. 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.

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 (1,665 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 (1,850 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.

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.

±139°, ±142°

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 = 49, 000 \cdot 0.333 = 16, 333

≈ 16,333

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.

Torpedo detectability1.4 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{1.4 km}{64 kt \times 2.6855} = 8.1 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.

8.1 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 2.82 per hit, shown as

2.82 \times 100 = 282 %

. 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.

Each ~2 s wave fires 2 quick salvos of 1 clouds ahead of the attacking squadron - up to 2 clouds per wave × 190 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.

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 (32.9 kt of 36.5 kt), from our in-house acceleration model.

18.7 s

Acceleration 0-99%

Time to reach 99% of top speed (36.1 kt of 36.5 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.

32 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{36.5 \cdot 0.5144}{630} = 1.71 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{15}{1.71} = 8.8 \times

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{10900}{30} \cdot \frac{8 - 0.5}{1000} + 0.5) \cdot 30 = 96.8 m$

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 Disp58.1 m at 10.9 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 96.8 \cdot 0.6 = 58.1 m$

Shell scatter height @ 10 km52.5 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  $delim \cdot R_{m a x} = 0.5 \cdot 10900 = 5450$  m, and  $radiusOnMax = 0.6$  at 10900 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 5450}{10900 - 5450} = 0.5835$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5835 = 52.5 m$ .

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2438 \cdot {22.68}^{0.69} \cdot {0.12}^{- 1.07} \cdot 808^{1.38} = 208.9 mm$ . Matches the in-game spec card.

AP Pen Far42.1 mm at 10.9 km

Same formula at the ship's max firing range (10.9 km), where the shell has slowed to 252.9 m/s:  $P = 10^{- 7} \cdot 2438 \cdot {22.68}^{0.69} \cdot {0.12}^{- 1.07} \cdot {252.9}^{1.38} = 42.1 mm$ .

AP pen 5 km92 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 km46 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.

HE flight time @ 10 km8.6 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3927 \cdot {0.12}^{2}}{8 \cdot 22.68} = 9.79 \times 10^{- 5}$ . That runs from a 808 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 penetration20 mm

20 mm ≈ 120 mm caliber / 6 (standard HE penetration ratio).

AP overmatch8 mm

floor(120 mm caliber / 14.3) = 8 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius8

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.

Torpedoes

Torpedo detectability1.4 km

Estimated torpedo reaction time8.1 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 range48.2 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

1 launchers x 4 tubes.

Per-side salvo4 torpedoes

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

Full-salvo damage65,332

All tubes hitting one target: tubes x per-torpedo simulated damage = 4 x 16,333 = 65,332.

Per-side salvo damage65,332

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 4 x 16,333 = 65,332.

AA defense

AA DPS at max range18

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 2 pdr MkVII Quad 1x4 -> 35 DPS @ 2.5 km; 20mm Oerlikon MK V 6x2 -> 113 DPS @ 2 km; 4in45 QF Mk XIX 1x2 -> 18 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 range18 DPS @ 5 km, 53 DPS @ 2.5 km, 166 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-blank166

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

AA threat index404

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 @ 4 km258 m

4 km × 57 + 30 = 258 m.

Secondary battery firepower

Secondary DPM (per side)30,000

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: 1×2 102 mm (1/side) × 60/3 × 1500 = 30,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha1500

Maximum HE damage per shell across secondary HE families. Best on this ship: 1500 from the 102 mm family.

Max HE fire chance6%

Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 6% from the 102 mm family.

Max HE pen17 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: 17 mm from the 102 mm family.

Armor Beta

Hull HP 18,500, 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 141+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

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

Hull (midship)	19 mm	13,900 (75% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)Angle bounces 203mm19 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 15–19 mm)	1,500 (8% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)Angle bounces 203mm16 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	20 mm primary (range 10–20 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.
Turret (module, per magazine)	separate HP pool, does not drain ship HP	9,300 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 (102 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	5,600 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.
