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.

Signature Traits

Big torpedo salvo ↗

10 tubes per side, best of T8 DDs. More torpedoes per launch: spread wide to cover a reposition, or tight for more hits on a thin target.

Long-duration sonar ↗

180 s Sonar duration, best of T8 DDs.

ELITE SMOKE ↗

Extra smoke charges · 6 Smoke
Fast smoke cycle · 60 s

ELITE MAIN BATTERY ↗

Slow for the class ↗

34 kt, bottom quartile of T8 DDs. Hard to rotate flanks or disengage; commit positioning early.

Weak torpedoes ↗

10833 damage per torpedo, bottom quartile of T8 DDs.

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.

Fire duration30 s

Fire damage

One unattended fire: 0.003 of max HP per second (0.3%) × 30 s = 0.09 of the pool; 0.09 × 20,100 HP = 1,809 HP on this ship. 4 fire points can burn at once.

Flood duration40 s

Flood damage

One unattended flood: 0.0025 of max HP per second (0.25%) × 40 s = 0.1 of the pool; 0.1 × 20,100 HP = 2,010 HP on this ship.

0.25% of HP per second

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.

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: 0.01 of max HP per second (1%) × 10 s × 20,100 HP = 2,010 HP per charge, × 2 charges = 4,020 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. Repair Party is one choice in its slot on this ship, so this applies only if you take it.

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 × 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.

3,300

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 × 15,100 = 30,200), 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.

15,100

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 × 1,400 = 2,800), 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.

Projectile speed60.0 kt

Range12 km

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 = 32, 500 \cdot 0.333 = 10, 833

. 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.

≈ 10,833

Maximum damage (ammunition)

32,500 warhead alpha / 3 + 1,000 blast = 11,833. 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.

11,833

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.

1,000

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

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

7.4 s

Flooding chance

This torpedo carries a flooding-chance value of 2.8 per hit, shown as

2.8 \times 100 = 280 %

. 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 × 230 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.

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 salvo. Often called flak 'hit chance', but spawned clouds always damage planes that fly into them - the roll is on spawning.

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

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.

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 km24.9 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  $delim \cdot R_{m a x} = 0.5 \cdot 10913 = 5456$  m, and  $radiusOnMax = 0.6$  at 10913 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{5456} = 0.4749$ , so  $σ_{V} = σ_{H} \cdot k = 52.5 \cdot 0.4749 = 24.9 m$ .

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, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 1600 \cdot 25^{0.69} \cdot {0.113}^{- 1.07} \cdot {498.8}^{1.38} = 80 mm$ , where 498.8 m/s is the shell's speed when it arrives at 5 km (from 746 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 km49 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 1600 \cdot 25^{0.69} \cdot {0.113}^{- 1.07} \cdot {347.1}^{1.38} = 49 mm$ , where 347.1 m/s is the shell's speed when it arrives at 10 km (from 746 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 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 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 km7.46 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3296 \cdot {0.113}^{2}}{8 \cdot 25} = 6.61 \times 10^{- 5}$ . 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 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)6

3 mounts × 2 barrels = 6; all 6 bear on the broadside.

Model inputs

Krupp (AP)1,600

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 coefficient0.3296

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

AP muzzle velocity746 m/s

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

HE muzzle velocity746 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 time7.4 s

1200 m / (60.0 kt × 2.6855) = 7.4 s. detectability / (speed kt x 2.6855 m/s per knot on the game clock).

Torpedo speed60.0 kt

Travel time to max range74.5 s

12000 m / (60.0 kt × 2.6855) = 74.5 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 damage108,330

All tubes hitting one target: tubes x per-torpedo simulated damage = 10 x 10,833 = 108,330. Each hit on the target's torpedo belt is reduced by its torpedo protection %.

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.

AA DPS layered by range67 DPS @ 5 km, 201 DPS @ 3.5 km

@ 5 km: 67 from one family; @ 3.5 km: 80 + 27 + 27 + 67 = 201. 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

80 + 27 + 27 + 67 = 201 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (3.5 km).

AA threat index804

80 × 3.5 + 27 × 3.5 + 27 × 3.5 + 67 × 5 = 804. 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

The Battle-class destroyers, featuring enhanced AA defenses, were designed drawing on lessons learned from wartime and ordered by the Admiralty in 1942 and 1943. The ships ordered in 1943 differed from their earlier counterparts by having more powerful main battery artillery, and among them was destroyer HMS Somme, named after one of the biggest battles of World War I. However, she was never commissioned and remained unclaimed due to the end of hostilities in 1945. She was eventually demolished on her stocks.

Armor Beta

Hull HP 20,100, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds.

Bow & stern19 mm

Overmatched by 134+ 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.
