Duguay-Trouin Build & Guide | WoWs Legends

Playstyle

Overview

Duguay-Trouin is a Tier III French light cruiser with Sonar as her vision tool. Hydro lets her contest islands and smoke without exposing the hull to vision cycles, which shapes how she pressures caps. Standout traits: best high HP pool in T3 CAs (26,700 HP) and best engine power in T3 CAs (100,000 HP).

Positioning

Sit 10-13 km from a contested cap where an island shadows you from the opposite battleship line. Hydro (3.9 km on ships, 2.8 km on torpedoes) lights up DDs and incoming torpedoes inside its bubble, so you can push the cap edge from cover without taking the spotting cycle; prefer cover positions over open-water flanks.

Potato Avoidance

Open-water broadside trading

Her 155mm shells citadel cruisers on the wrong frame, and her 26,700-HP hull does not recover from a punished salvo. Pick rotations and angles deliberately; the chip-damage role pays better than the trade-blow role on a cruiser of this profile.

Signature Traits

Big-caliber overmatch

10.8 mm overmatch threshold, best of T3 CAs. Punishes bow-tanking ships peers can't crack.

Close-range AP brick

259.7 mm AP pen at 1.5 km, best of T3 CAs. Citadels broadside cruisers up close.

Long-range AP brick

77.7 mm AP pen at max range, best of T3 CAs. Threatens citadels even from range.

High HP pool

26700.0 HP, best of T3 CAs.

Stiff AP fuse

26.0 mm AP arming threshold, worst of T3 CAs. Over-pens thin plates; the trade-off pays off when most targets are battleship belt armor.

Sluggish rudder

10.2 s rudder shift, worst of T3 CAs. Hard to dodge incoming AP; lean on island cover.

AL Saint Louis, Andre Lemmonier, and Andre Roux are useful French cruiser commander directions. Inspirations usually support accuracy, reload, concealment, agility, or survivability so the ship can keep influencing fights without giving up easy citadels.

Armor

Hull HP 22,900 → 26,700 with hull upgrade, 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	30 mm primary (range 13–30 mm)	3,600 (13% of HP)	Overmatch not possible at T IVAngle bounces 410mm30 mm: HE pens from 203mm+	Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.
Hull (midship)	14 mm	20,000 (75% of HP)	Overmatched by 203mm+ (Desert Falcon, Genova)Angle bounces 152mm14 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.

Citadel	20 mm primary (range 13–20 mm)	≈ 165,500 (effectively no cap)	Citadel pen ×0.10 damageOver-pen: ×0.10 damage	Effectively no cap; citadel pool sits at ~165k HP on every ship. Damage is gated by pen/over-pen multipliers instead (×0.10 direct pen, ×0.10 over-pen).
Superstructure	10 mm primary (range 10–30 mm)	1,000 (4% 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	13,400 magazine HP	Magazine detonation1–30% chance · below ~75% HP	Per-turret powder-magazine HP. Detonation chance scales from 1% (no mag damage) to 30% (full mag damage); this range is the in-game value. Detonation can't roll while the ship is above ~75% HP (the standard detonation-protection threshold, not a per-ship stat). Smaller magazines saturate to the 30% ceiling faster.
AA mount (75 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	8,000 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.
