Overview

Marceau SE 25 is a Tier VIII French 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. With no smoke to reset a bad trade, her positioning has to do the work the consumable would. Her 127mm guns reload in 4 s. Both shells run cohort-strong (top-decile AP at 282,000 AP DPM and cohort-best HE at 222,000 HE DPM), making her a dual-threat gunship: keep AP up against broadsides and citadels, and switch to HE against bow-in ships, superstructures, and the thin or angled targets AP over-penetrates or bounces off. She also packs the super-heal (1%/s, for 14 s, every 120 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 top speed in T8 DDs (44 kt, 1st of 28) and best Engine Boost duration in T8 DDs (180 s, 2nd of 21). The trade is torpedo reload in T8 DDs (150 s, 25th of 27).

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. A 740 m turning circle is wide for her cohort, so a committed turn gives up a lot of water; plan course changes a salvo ahead.

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. With no smoke to break the trade you cannot choose when it ends, and 20,500 HP is the whole budget.

Signature Traits

Torpedoes on both beams

Two launchers on each beam, 6 tubes per side. Each launcher reloads on its own, so she can fire one side, turn and fire the other without waiting, or ambush ships on both sides of an island at once, shared by 5/28 T8 DDs.

Engine Boost

+20% speed (about +8.8 kt), 180 s duration. Engine Boost consumable temporarily raises top speed. Mobility on demand to reposition, chase a kill, or break contact.

Fire damage

One unattended fire: 0.003 of max HP per second (0.3%) × 30 s = 0.09 of the pool; 0.09 × 20,500 HP = 1,845 HP on this ship. 4 fire points can burn at once.

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.

11,000

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.

6,200

Effective HP

Base 20,500 HP plus everything Repair Party can restore: 0.01 of max HP per second (1%) × 14 s × 20,500 HP = 2,870 HP per charge, × 2 charges = 5,740 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 × 2,900 = 5,800), 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.

2,900

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 × 15,400 = 30,800), 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.

15,400

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 × 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 × 2,000 = 4,000), 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.

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.

Guns to bear

180° − 153° (the most restricted aft-facing mount's arc) = 27° off bow; 180° − 153° (the most restricted forward-facing mount's arc) = 27° 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 = 41, 200 \cdot 0.333 = 13, 733

. 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.

≈ 13,733

Maximum damage (ammunition)

41,200 warhead alpha / 3 + 1,100 blast = 14,833. 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.

14,833

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.

1,100

Torpedo detectability1.5 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{1.5 km}{60 kt \times 2.6855} = 9.3 s

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

9.3 s

Flooding chance

This torpedo carries a flooding-chance value of 2.46 per hit, shown as

2.46 \times 100 = 246 %

. 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 × 240 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 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 5.2 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 km24.8 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  $delim \cdot R_{m a x} = 0.5 \cdot 11045 = 5522$  m, and  $radiusOnMax = 0.6$  at 11045 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{5522} = 0.4716$ , so  $σ_{V} = σ_{H} \cdot k = 52.5 \cdot 0.4716 = 24.8 m$ .

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  $delim \cdot R_{m a x} = 0.5 \cdot 11045 = 5522$  m, and  $radiusOnMax = 0.6$  at 11045 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 5522}{11045 - 5522} = 0.5811$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5811 = 52.3 m$ .

AP pen 5 km114 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2200 \cdot {32.5}^{0.69} \cdot {0.127}^{- 1.07} \cdot {490.5}^{1.38} = 114 mm$ , where 490.5 m/s is the shell's speed when it arrives at 5 km (from 808 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 km62 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2200 \cdot {32.5}^{0.69} \cdot {0.127}^{- 1.07} \cdot {314.8}^{1.38} = 62 mm$ , where 314.8 m/s is the shell's speed when it arrives at 10 km (from 808 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 km7.81 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.42 \cdot {0.127}^{2}}{8 \cdot 31.5} = 8.45 \times 10^{- 5}$ . 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 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 km7.67 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.42 \cdot {0.127}^{2}}{8 \cdot 32.5} = 8.19 \times 10^{- 5}$ . 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 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)8

4 mounts × 2 barrels = 8; all 8 bear on the broadside.

Model inputs

Krupp (AP)2,200

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 mass32.5 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 coefficient0.42

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

AP muzzle velocity808 m/s

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

HE muzzle velocity808 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 time9.3 s

1500 m / (60.0 kt × 2.6855) = 9.3 s. detectability / (speed kt x 2.6855 m/s per knot on the game clock).

Torpedo speed60.0 kt

Travel time to max range37.2 s

6000 m / (60.0 kt × 2.6855) = 37.2 s. range / (speed kt x 2.6855 m/s per knot on the game clock).

Tube count12

4 launchers × 3 tubes.

Per-side salvo6 torpedoes

12 wing tubes / 2 = 6: the launchers sit one per beam, so only half of them reach any one side. Each launcher reloads on its own, so she can fire one beam, turn, and fire the other without waiting.

Full-salvo damage164,796

All tubes hitting one target: tubes x per-torpedo simulated damage = 12 x 13,733 = 164,796. Each hit on the target's torpedo belt is reduced by its torpedo protection %.

AA defense

AA DPS at max range88

Only families that reach 5.2 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors Mk2 3x4 -> 82 DPS @ 3.5 km; 40mm Bofors Mk1 2x2 -> 55 DPS @ 3.5 km; 20mm Oerlikon MK20 Twin 4x2 -> 53 DPS @ 2 km; Far AA (?) -> 88 DPS @ 5.2 km.

AA DPS layered by range88 DPS @ 5.2 km, 225 DPS @ 3.5 km, 278 DPS @ 2 km

@ 5.2 km: 88 from one family; @ 3.5 km: 82 + 55 + 88 = 225; @ 2 km: 82 + 55 + 53 + 88 = 278. 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-blank278

82 + 55 + 53 + 88 = 278 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index1043

82 × 3.5 + 55 × 3.5 + 53 × 2 + 88 × 5.2 = 1043. 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

In 1939, amid rising worldwide tensions, it was decided to continue building destroyer leaders and increase the number of Mogador-class ships to six. Destroyer Marceau was never laid down, and construction work was suspended after France declared war on Germany. If the construction had continued after the war, the ship could have received American 5-inch (127 mm) dual-purpose guns.

Armor Beta

Hull HP 20,500, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are estimates.

Bow & stern19 mm

Overmatched by 134+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Farming19 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

Hull (midship)	19 mm	≈ 15,375 (~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 19–20 mm)	≈ 1,025 (~5% 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 13–20 mm)	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	19 mm	no cap	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).

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.
