Overview

Duncan is a Tier VIII British fast battleship at 32 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. She also packs the super-heal (2%/s, for 20 s, every 80 s, 2 charges): each Repair Party charge returns dramatically more HP than a standard heal, so her durability comes from sustain alongside the lead trait. Standout traits: best deep effective HP in T8 BBs (135,360, 1st of 33) and best torpedo alpha in T8 BBs (27,867, 1st of 7). The trade is thin end plates in T8 BBs (25 mm, 31st of 31).

Positioning

Anchor a flank at 14-17 km with bow toward the closest threat, then use the speed advantage at 32 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.

Potato Avoidance

Using the 32-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 takes her to 34.6 kt, faster than 30 of 37 T8 cruisers - enough to run down most cruisers or pull away from them, though destroyers still outpace her. Uncommon in T8 BBs.

Deep effective HP ↗

135360 effective HP once Repair Party is counted, best of T8 BBs. Absorbs more total punishment than the raw HP pool suggests.

Heavy torpedoes ↗

27867 damage per torpedo, best of the 7 T8 BBs with torpedoes.

ELITE MOBILITY ↗

Fast for the class · 32 kt
Quick acceleration

Big-caliber AP overmatch ↗

29.3 mm AP overmatch threshold, top decile of T8 BBs. Punishes bow-tanking ships peers can't crack.

Thin end plates

25 mm bow and stern plating, both in the bottom bracket of T8 BBs. AP above 150 mm of caliber cannot arm on 25 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; 380 mm AP and up overmatches it at any angle.

Fire resistance

top hull: 1 − 0.6004 fire coefficient = 40%. Lowers how often hits set you on fire. It does not reduce the damage a burning fire does per second; fires burn at the full rate on every ship.

40%

Fire duration60 s

Fire damage

One unattended fire: 0.003 of max HP per second (0.3%) × 60 s = 0.18 of the pool; 0.18 × 75,200 HP = 13,536 HP on this ship. 4 fire points can burn at once.

0.3% of HP per second

Flood duration40 s

Flood damage

One unattended flood: 0.005 of max HP per second (0.5%) × 40 s = 0.2 of the pool; 0.2 × 75,200 HP = 15,040 HP on this ship.

0.5% of HP per second

Torp Reduction

1 − 0.257 hull torpedo-damage coefficient / 0.333 unprotected baseline = 23%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.

23%

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.

37,600

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.

22,600

Effective HP

Base 75,200 HP plus everything Repair Party can restore: 0.02 of max HP per second (2%) × 20 s × 75,200 HP = 30,080 HP per charge, × 2 charges = 60,160 HP. Ceiling, not a prediction: a charge only restores damage actually taken, and only the regeneratable share of it. In practice ships realize about half of this, mostly because half the charges go unspent; a charge that is used returns about 97% of the per-charge figure above.

Bow section HP

Damage saturation pool for the bow: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 5,700 = 11,400), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

5,700

Casemate section HP

Damage saturation pool for the casemate: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 7,000 = 14,000), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

7,000

Hull section HP

Damage saturation pool for the hull: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 56,400 = 112,800), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

56,400

Superstructure section HP

Damage saturation pool for the superstructure: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 6,600 = 13,200), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. The superstructure is not exempt: it saturates exactly like the bow and stern, so shells aimed at it stop dealing full damage once this pool is used up. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

6,600

Stern section HP

Damage saturation pool for the stern: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 3,300 = 6,600), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.

Citadel section HP

This section has no practical saturation cap: every hit here keeps dealing its normal share of damage (on most ships the citadel; on many destroyers the casemate).

Turret traverse arcs

How far each mount can train, in degrees to either side of the mount's own facing. 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 ±150°

Guns to bear

180° − 159° (the most restricted aft-facing mount's arc) = 21° off bow; 180° − 150° (the most restricted forward-facing mount's arc) = 30° off stern. 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.

Maximum simulated damage

Most targets only intersect one hull section, so a hit transfers about 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 = 83, 600 \cdot 0.333 = 27, 867

. In battle, a hit on the torpedo belt deals the per-hit figure × (1 − the target's torpedo protection %), a bow or stern hit deals it in full, and a torpedo never counts as a citadel hit.

≈ 27,867

Maximum damage (ammunition)

83,600 warhead alpha / 3 + 1,500 blast = 29,367. Warhead alpha / 3 plus the blast addend: the per-torpedo damage figure. The 'Maximum simulated damage' row above applies target geometry to the same warhead.

29,367

Torpedo module damage

Per-torpedo module/blast damage parameter. 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.

1,500

Torpedo detectability1.7 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{1.7 km}{67 kt \times 2.6855} = 9.4 s

. 2.6855 converts knots to m/s on the game clock. Base value; commander torpedo-concealment skills lower it further.

9.4 s

Flooding chance

This torpedo carries a flooding-chance value of 3.55 per hit, shown as

3.55 \times 100 = 355 %

. 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.

AA explosions

Each ~2 s salvo fires 2 AA explosions in quick succession, each leaving 3 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between salvos - up to 7 clouds per salvo × 220 damage each. Planes that fly into a cloud take its damage; clouds dissipate before the next salvo lands. Defensive AA Fire, where fitted, multiplies the AA explosions within each salvo, and commander skills that raise the Number of AA explosions add to it.

2 per salvo, 3 clouds each + 1 outer cloud

Cloud damage

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

220

Cloud spawn chance

Each cloud in the pattern rolls this chance to spawn, so salvos 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%

Salvo interval

A new flak salvo (the AA explosions above) fires roughly every 2 s.

every ~2 s

Fired by

Flak keeps firing while at least one secondary battery mount is operational - even losing every dedicated 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 clouds can land short of 2.5 km or past 5 km - once planes get inside the band, new salvos stop. AA range bonuses push the outer edge out; the 2.5 km inner edge does not move.

Sum across all secondary families of (per-side barrels × 60 / reload_s × alpha), with each reload counted in whole 1/7 s ticks (guns fire on the first tick after the reload), where per-side barrels = mounts × barrels-per-mount / 2 (the guns that bear on one broadside target). Per-family: 8×2 114 mm (8/side) × 60/5 s × 1700 = 163,200 + 6×2 152 mm (6/side) × 60/12 s × 2150 = 64,500.

Main battery formulas

vs standard BB17% tighter H · 17% shorter V

H = horizontal, V = vertical spread. This ship's curve against the standard battleship curve, both evaluated at this ship's max range (17.0 km) with the same model as Max Horiz/Vert Disp: horizontal 191 / 230 m − 1 = -17%, vertical 114 / 138 m − 1 = -17%. Shell grouping (σ) is separate: it sets how shells bunch toward the centre of this ellipse.

Shell scatter width @ 5 km90 m

(166.7 × (10 − 1.6) / 1000 + 1.6) × 30 = 90 m. Horizontal scatter at a fixed 5 km, from the same dispersion model as the rows below - a knife-fight-range anchor comparable across ships.

Shell scatter width @ 10 km132 m

(333.3 × (10 − 1.6) / 1000 + 1.6) × 30 = 132 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

(500 × (10 − 1.6) / 1000 + 1.6) × 30 = 174 m. Horizontal scatter at a fixed 15 km, from the same dispersion model - the long-range anchor. Only shown when the ship's guns reach 15 km.

Shell scatter height @ 5 km33.9 m

How tall the scatter ellipse is at a fixed 5 km, from the same model, comparable from ship to ship. 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  $delim \cdot R_{m a x} = 0.5 \cdot 16973 = 8486$  m, and  $radiusOnMax = 0.6$  at 16973 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{8486} = 0.3768$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.3768 = 33.9 m$ .

Shell scatter height @ 10 km68.4 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  $delim \cdot R_{m a x} = 0.5 \cdot 16973 = 8486$  m, and  $radiusOnMax = 0.6$  at 16973 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 8486}{16973 - 8486} = 0.5178$ , so  $σ_{V} = σ_{H} \cdot k = 132 \cdot 0.5178 = 68.4 m$ .

Shell scatter height @ 15 km100.4 m

How tall the scatter ellipse is at a fixed 15 km, from the same model. Only shown when the ship's guns reach 15 km. 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  $delim \cdot R_{m a x} = 0.5 \cdot 16973 = 8486$  m, and  $radiusOnMax = 0.6$  at 16973 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{15000 - 8486}{16973 - 8486} = 0.5768$ , so  $σ_{V} = σ_{H} \cdot k = 174 \cdot 0.5768 = 100.4 m$ .

AP pen 5 km689 mm

AP penetration at a fixed 5 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2548 \cdot 1157^{0.69} \cdot {0.419}^{- 1.07} \cdot {685.7}^{1.38} = 689 mm$ , where 685.7 m/s is the shell's speed when it arrives at 5 km (from 747 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 10 km615 mm

AP penetration at a fixed 10 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2548 \cdot 1157^{0.69} \cdot {0.419}^{- 1.07} \cdot {631.5}^{1.38} = 615 mm$ , where 631.5 m/s is the shell's speed when it arrives at 10 km (from 747 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 15 km554 mm

AP penetration at a fixed 15 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2548 \cdot 1157^{0.69} \cdot {0.419}^{- 1.07} \cdot {585.7}^{1.38} = 554 mm$ , where 585.7 m/s is the shell's speed when it arrives at 15 km (from 747 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

HE flight time @ 10 km5.23 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.31 \cdot {0.419}^{2}}{8 \cdot 995} = 2.15 \times 10^{- 5}$ . That runs from a 792 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77 because the game clock runs faster than real time. Lower is better, since a faster shell is harder to dodge and needs less lead.

AP flight time @ 10 km5.29 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2353 \cdot {0.419}^{2}}{8 \cdot 1157} = 1.4 \times 10^{- 5}$ . That runs from a 747 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77 because the game clock runs faster than real time. Lower is better, since a faster shell is harder to dodge and needs less lead.

AP shell mass1,157 kg

Enters penetration as mass^0.69 and slows the shell's drag deceleration, so a heavier shell keeps more velocity at range.

AP drag coefficient0.2353

Air drag on the AP shell in flight; lower keeps velocity, and with it penetration, at long range.

All tubes hitting one target: tubes x per-torpedo simulated damage = 2 x 27,867 = 55,734. Each hit on the target's torpedo belt is reduced by its torpedo protection %.

AA defense

AA DPS at max range63

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 2 pdr MkVIII 8barrel 4x8 -> 97 DPS @ 2.5 km; 40mm Bofors Mark IV Hazemeyer 10x2 -> 281 DPS @ 3.5 km; 20mm Oerlikon MK4 18x1 -> 112 DPS @ 2 km; 20mm Oerlikon MK V 10x2 -> 62 DPS @ 2 km; 114mm 45 MKIII 8x2 -> 63 DPS @ 5 km.

AA DPS layered by range63 DPS @ 5 km, 344 DPS @ 3.5 km, 441 DPS @ 2.5 km, 615 DPS @ 2 km

@ 5 km: 63 from one family; @ 3.5 km: 281 + 63 = 344; @ 2.5 km: 97 + 281 + 63 = 441; @ 2 km: 97 + 281 + 112 + 62 + 63 = 615. 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-blank615

97 + 281 + 112 + 62 + 63 = 615 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index1889

97 × 2.5 + 281 × 3.5 + 112 × 2 + 62 × 2 + 63 × 5 = 1889. 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.

Max HE alpha2150

max(1700 (114 mm), 2150 (152 mm)) = 2150. Maximum HE damage per shell across secondary HE families. Best on this ship: 2150 from the 152 mm family.

Max HE fire chance9%

max(8% (114 mm), 9% (152 mm)) = 9%. 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

max(19 mm (114 mm), 25 mm (152 mm)) = 25 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.

Background

The G3 project became the development of the 1920 series of battlecruisers. The reduction of the gun caliber to 16.5 inches (419 mm), as well as the length and displacement, was what distinguished it from previous optimistic designs. In the beginning of 1921, the project was reworked to increase the ship’s protection at the expense of speed and gun caliber. According to an order issued in October 1921, four ships of the project were to be constructed, but the process was halted due to the beginning of the Washington Conference and was later canceled based on its results.

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	22,600 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.
