Overview

Fletcher is a Tier VII American 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 127mm guns reload in 3 s, so the damage comes from staying in the trade rather than from any one salvo. Standout traits: HE DPM in T7 DDs (190,000, 3rd of 35) and AA DPS in T7 DDs (260, 7th of 42). The trade is HE fire chance in T7 DDs (5, 31st of 35).

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: 11 km of reach against 7.1 km of detection leaves about 3.9 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. Shooting from the cloud gives you away at 2.6 km, and a destroyer here is spotted at about 7 km, so you see it coming with roughly 4.3 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 9.4 km) read straight in regardless. She is genuinely evasive in both phases of a turn, answering the helm in 3 s and carving a 560 m circle, so you can break a salvo and still be where you meant to go.

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 7.1 km with 16,700 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.

ELITE MAIN BATTERY ↗

HE DPM machine · 190000 HE
Fast turret traverse · 34°/s
Gun-boat DD

Top-tier AA ↗

260 AA DPS, top quartile of T7 DDs (median 166).

Lingering smoke ↗

124 s smoke cloud linger, best of T7 DDs. Each puff stays up longer after you stop laying it, holding the shield.

Big torpedo salvo ↗

10 tubes per side, top decile of T7 DDs. More torpedoes per launch: spread wide to cover a reposition, or tight for more hits on a thin target.

Low fire chance ↗

5% fire chance per HE shell, bottom quartile of T7 DDs. AP carries more weight.

U.S. Tech Tree

Fletcher sits in the Universal Destroyers branch. The highlighted path shows the local branch context inside the full U.S. tree.

U.S. destroyers are "jacks-of-all-trades" and masters of none. They can perform in nearly any role needed from a destroyer: spotting the enemy, showering them in fire-starting shells, or unleashing torpedoes.

Advantages: Adaptable, Long-duration Smoke Generator
Disadvantages: Lackluster torpedo armament, Low-velocity shells

Fire damage

One unattended fire: 0.003 of max HP per second (0.3%) × 30 s = 0.09 of the pool; 0.09 × 16,700 HP = 1,503 HP on this ship. 4 fire points can burn at once.

Torp Reduction

1 − 0.333 hull torpedo-damage coefficient / 0.333 unprotected baseline = 0%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.

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.

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 × 2,200 = 4,400), 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.

2,200

Casemate 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).

No saturation cap

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 × 12,500 = 25,000), 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.

12,500

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 × 1,300 = 2,600), 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 ×. 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.

1,300

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 × 1,600 = 3,200), 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 ×. 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.

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°, ±142°, ±135°

Guns to bear

180° − 150° (the most restricted aft-facing mount's arc) = 30° off bow; 180° − 135° (the most restricted forward-facing mount's arc) = 45° 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.

Torpedoes

ModuleTorpedoes: Mk15 mod. 3

Launchers / tubes2 launchers × 5 tubes = 10 tubes

Reload time

Base reload of the top torpedo module (all-upgrades configuration); the stock module reloads in 105 s. Modernizations and commander effects scale it further, e.g. Torpedo Launchers Mod. 3 alone is x0.85:

115 \times 0.85 = 97.8

Initial: 105 s → 115 s

Projectile speed

Speed of the top torpedo module (all-upgrades configuration, 62.0 kt); the stock torpedo module runs 55.0 kt.

Initial: 55 kt → 62 kt

RangeInitial: 9.2 km → 10.5 km

Maximum simulated damage

Initial: 32,100 × 0.333 = 10,700 → 46,600 × 0.333 = 15,533 (warhead alpha × saturation coefficient, stock → upgraded torpedo). 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 = 46, 600 \cdot 0.333 = 15, 533

. 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.

Initial: ≈ 10,700 → ≈ 15,533

Maximum damage (ammunition)

46,600 warhead alpha / 3 + 1,100 blast = 16,633. 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.

16,633

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.

Torpedo detectability1.1 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{1.1 km}{62 kt \times 2.6855} = 6.6 s

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

6.6 s

Flooding chance

This torpedo carries a flooding-chance value of 2.79 per hit, shown as

2.79 \times 100 = 279 %

. 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 2 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between salvos - up to 5 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.

Flak keeps firing while at least one main battery mount is operational - even losing every dedicated 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 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.

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, using the ship's own reverse-power ratio. The full curve is on the acceleration chart. Full reverse stops about a quarter faster than a plain Stop order from top speed.

16.3 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.

Guns in a full turn

With the rudder hard over the hull turns 8.3°/s, so a target drifts across the bow at that rate. Turret traverse minus hull turn: 34 − 8.3 = +25.7°/s, so the guns hold the target through the turn. Main Battery Mod. 2 (+20% traverse) and Mod. 3 (−15%) move this line.

Main battery formulas

vs standard DDStandard

The standard destroyer dispersion curve.

Shell scatter width @ 5 km52.5 m

(166.7 × (8 − 0.5) / 1000 + 0.5) × 30 = 52.5 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 km90 m

(333.3 × (8 − 0.5) / 1000 + 0.5) × 30 = 90 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 height @ 5 km24.8 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  $delim \cdot R_{m a x} = 0.5 \cdot 11028.6 = 5514$  m, and  $radiusOnMax = 0.6$  at 11028.6 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{5514} = 0.472$ , so  $σ_{V} = σ_{H} \cdot k = 52.5 \cdot 0.472 = 24.8 m$ .

Shell scatter height @ 10 km52.3 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  $delim \cdot R_{m a x} = 0.5 \cdot 11028.6 = 5514$  m, and  $radiusOnMax = 0.6$  at 11028.6 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 5514}{11028.6 - 5514} = 0.5813$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5813 = 52.3 m$ .

AP pen 5 km115 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2598 \cdot 25^{0.69} \cdot {0.127}^{- 1.07} \cdot {498.5}^{1.38} = 115 mm$ , where 498.5 m/s is the shell's speed when it arrives at 5 km (from 792 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 km65 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2598 \cdot 25^{0.69} \cdot {0.127}^{- 1.07} \cdot {328.8}^{1.38} = 65 mm$ , where 328.8 m/s is the shell's speed when it arrives at 10 km (from 792 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP flight time @ 10 km7.51 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3 \cdot {0.127}^{2}}{8 \cdot 25} = 7.6 \times 10^{- 5}$ . 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.

HE flight time @ 10 km7.6 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3 \cdot {0.127}^{2}}{8 \cdot 24.5} = 7.76 \times 10^{- 5}$ . 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.

Guns per full salvo (alpha, DPM)5

5 mounts × 1 barrels = 5; all 5 bear on the broadside.

Model inputs

Krupp (AP)2,598

Armor-penetration constant of the AP shell; penetration scales straight with it, so a 10% higher Krupp is 10% more penetration at every range.

AP shell mass25 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 coefficient0.3

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

AP muzzle velocity792 m/s

Starting speed of the AP shell; penetration scales with velocity^1.38.

HE muzzle velocity792 m/s

Starting speed of the HE shell; sets its flight time and lead.

idealRadius8

Horizontal dispersion growth per idealDistance of range, in 30 m units; the slope of the scatter-width line.

minRadius0.5

Horizontal dispersion at zero range, in 30 m units; the intercept of the scatter-width line.

idealDistance1,000 m

Range step over which horizontal dispersion grows by idealRadius.

taperDist4,000 m

Inside this range the scatter width tapers toward minRadius instead of following the line.

radiusOnZero0.2

Vertical scatter as a share of horizontal at zero range.

radiusOnDelim0.5

Vertical scatter as a share of horizontal at the delim point.

radiusOnMax0.6

Vertical scatter as a share of horizontal at maximum range.

delim0.5

Where the vertical-scatter curve bends, as a share of maximum range.

Torpedoes

Estimated torpedo reaction time6.6 s

1100 m / (62.0 kt × 2.6855) = 6.6 s. detectability / (speed kt x 2.6855 m/s per knot on the game clock).

Torpedo speed62.0 kt

Travel time to max range63.1 s

10500 m / (62.0 kt × 2.6855) = 63.1 s. range / (speed kt x 2.6855 m/s per knot on the game clock).

Tube count10

2 launchers × 5 tubes.

Per-side salvo10 torpedoes

2 launchers × 5 tubes = 10, all to either side (centreline launchers train across - full salvo to either side).

Full-salvo damage155,330

All tubes hitting one target: tubes x per-torpedo simulated damage = 10 x 15,533 = 155,330. Each hit on the target's torpedo belt is reduced by its torpedo protection %.

AA defense

AA DPS at max range84

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors Mk1 5x2 -> 116 DPS @ 3.5 km; 20mm Oerlikon MK4 7x1 -> 60 DPS @ 2 km; Far AA (?) -> 84 DPS @ 5 km.

AA DPS layered by range84 DPS @ 5 km, 200 DPS @ 3.5 km, 260 DPS @ 2 km

@ 5 km: 84 from one family; @ 3.5 km: 116 + 84 = 200; @ 2 km: 116 + 60 + 84 = 260. 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-blank260

116 + 60 + 84 = 260 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index946

116 × 3.5 + 60 × 2 + 84 × 5 = 946. 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.

Background

Fletcher belonged to the most numerous series of destroyers in the world. She proved to be a very successful ship combining high speed and efficient AA defenses, as well as powerful artillery and torpedo armament.

Armor Beta

Hull HP 14,400 → 16,700 with hull upgrade, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds.

Bow & stern19 mm

Overmatched by 137+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Section	Plates	HP cap	Threats	Tactic

Hull (midship)	19 mm	12,500 (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	19 mm primary (range 13–20 mm)	1,600 (10% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)Angle bounces 203mm19 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	20 mm primary (range 13–20 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.
Superstructure	13 mm primary (range 13–19 mm)	1,300 (8% 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	8,400 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 (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	5,000 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.
