Overview

Somme is a Tier VIII British stealth destroyer with cohort-best surface detection (6.9 km). The kit opens detection windows other DDs cannot, so her value is contesting caps her peer DDs cannot reach unspotted. Standout traits: best AP always-pen window in T8 DDs (60°) and best smoke duration in T8 DDs (20 s).

Positioning

Push deep into caps with 6.9 km detection - closer than peer DDs can match. The advantage opens windows for free torpedo drops and unspotted reposition; treat the cap as yours to take rather than yours to contest.

Potato Avoidance

Burning the 6.9 km concealment advantage on guns

Every salvo lights you up and gives back the detection edge that makes the kit work; reserve guns for finishing damage on already-spotted ships, and prioritize torpedo drops you can fire while undetected.

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.

40%

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 (1,809 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 (2,010 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.

10,100

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.

6,000

Effective HP

Base 20,100 HP plus everything Repair Party can restore: 1%/s x 10 s = 2,010 HP per charge, x2 charges = 4,020 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.

Projectile speed60 kt

Range12 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 = 32, 500 \cdot 0.333 = 10, 833

≈ 10,833

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.

11,833

Torpedo detectability1.2 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{1.2 km}{60 kt \times 2.6855} = 7.4 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.

7.4 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 2.8 per hit, shown as

2.8 \times 100 = 280 %

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

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.

Wave rate

A flak wave spawns roughly every 2 s - timed frame-by-frame from gameplay footage and consistent across ships.

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.

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.

15.4 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 (30.6 kt of 34 kt), from our in-house acceleration model.

6.8 s

Acceleration 0-99%

Time to reach 99% of top speed (33.7 kt of 34 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.

18 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{34.0 \cdot 0.5144}{610} = 1.64 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{20}{1.64} = 12.2 \times

Shell Grouping (σ)2

Max Horiz Disp96.8 m at 10.9 km

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{10913}{30} \cdot \frac{8 - 0.5}{1000} + 0.5) \cdot 30 = 96.8 m$

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  $delim \cdot R_{m a x} = 0.5 \cdot 10913 = 5456$  m, and  $radiusOnMax = 0.6$  at 10913 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 5456}{10913 - 5456} = 0.5833$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5833 = 52.5 m$ .

AP pen 5 km80 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ .

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 km7.46 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.329 \cdot {0.113}^{2}}{8 \cdot 24.95} = 6.61 \times 10^{- 5}$ . That runs from a 746 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 penetration19 mm

19 mm ≈ 114 mm caliber / 6 (standard HE penetration ratio).

AP overmatch7 mm

floor(114 mm caliber / 14.3) = 7 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 alpha6

All 6 barrels bear on the broadside.

Turret turn time9 s

180 degrees / 20 deg/s traverse speed = 9 s.

HE full-salvo alpha10,200

1,700 HE damage x 6 broadside guns = 10,200.

2,100 AP damage x 6 broadside guns = 12,600.

HE DPMInitial: 170,000 → 191,250

Zero upgrades: 10,200 HE full-salvo alpha x 60 / 3.6 s base reload = 170,000. All upgrades (Main Battery Mod. 3 = -10% reload): 10,200 HE full-salvo alpha x 60 / 3.2 s all-upgrades reload = 191,250.

AP DPMInitial: 210,000 → 236,250

Zero upgrades: 12,600 AP full-salvo alpha x 60 / 3.6 s base reload = 210,000. All upgrades (Main Battery Mod. 3 = -10% reload): 12,600 AP full-salvo alpha x 60 / 3.2 s all-upgrades reload = 236,250.

Shells/minInitial: 100 → 112.5

Zero upgrades: 6 broadside guns x 60 / 3.6 s base reload = 100. All upgrades (Main Battery Mod. 3 = -10% reload): 6 broadside guns x 60 / 3.2 s all-upgrades reload = 112.5.

Fires/minInitial: 8 → 9

Zero upgrades: 100 shells/min x 8% fire chance = 8. All upgrades (Main Battery Mod. 3 = -10% reload): 112.5 shells/min x 8% fire chance = 9.

Torpedoes

Torpedo detectability1.2 km

Estimated torpedo reaction time7.4 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 speed60 kt

Travel time to max range74.5 s

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

Torpedo module damage1,000

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 count10

2 launchers x 5 tubes.

Per-side salvo10 torpedoes

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

Full-salvo damage108,330

All tubes hitting one target: tubes x per-torpedo simulated damage = 10 x 10,833 = 108,330.

Per-side salvo damage108,330

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 10 x 10,833 = 108,330.

AA defense

AA DPS at max range67

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors MkV 3x1 -> 80 DPS @ 3.5 km; 40mm Bofors Twin 1x2 -> 27 DPS @ 3.5 km; STAAG MarkV 1x2 -> 27 DPS @ 3.5 km; Far AA (?) -> 67 DPS @ 5 km.

Maximum AA range5 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 range67 DPS @ 5 km, 201 DPS @ 3.5 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-blank201

Sum of every family's average DPS, achievable only inside the closest-range family (3.5 km).

AA threat index804

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 20,100, 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 & stern19 mm

Overmatched by 132+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Farming13 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 40%, fires burn 30s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	19 mm primary (range 19–20 mm)	3,300 (16% of HP)	Overmatched by 283mm+ AP (Scharnhorst '43, Schill)Angle bounces 203mm19 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)	19 mm primary (range 16–19 mm)	15,100 (75% of HP)	Overmatched by 283mm+ AP (Scharnhorst '43, Schill)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 16–20 mm)	1,400 (7% of HP)	Overmatched by 283mm+ AP (Scharnhorst '43, Schill)Angle bounces 203mm19 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	20 mm primary (range 19–20 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 (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	10,100 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	6,000 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.
