Overview

De Ruyter is a Tier III Dutch 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. AA (157 AA DPS at 3.5 km) is heavy enough to make her the team's air-defense anchor on top of the lead role; CV strikes route around her, not through. Standout traits: best torpedo belt percent in T3 CAs (10) and best main battery range in T3 CAs (13.3 km).

Positioning

Sit 10-13 km from a contested cap where an island shadows you from the opposite battleship line. Hydro (4.4 km on ships, 3.3 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 150mm shells citadel cruisers on the wrong frame, and her 25,500-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

Close-range AP brick

246.9 mm AP pen at 1.5 km, top decile of T3 CAs. Citadels broadside cruisers up close.

Long-range AP brick

74.7 mm AP pen at max range, top decile of T3 CAs. Threatens citadels even from range.

Strong torpedo belt

10.0% torpedo damage reduction, best of T3 CAs.

Long gun range

13.27 km main battery reach, best of T3 CAs.

Flat AP shells

900.0 m/s AP muzzle velocity, best of T3 CAs. Flatter trajectory, less lead, harder to dodge.

Slow acceleration

~10.5 s to max forward speed, bottom decile of T3 CAs. Sluggish rebuild after a turn or stop. (Acceleration decode is validated in-game but not yet confirmed across every ship.)

Acquisition

How to get De Ruyter

De Ruyter is available in the Early Dutch Cruisers branch of the Netherlands Tech Tree for 85,000 credits after researching it in the branch. Known module upgrades cost up to 21,240 credits.

Builds Beta

Use a The Netherlands cruiser commander focused on reload, range, agility, and survivability. Inspirations that improve dispersion, rudder/steering, concealment, or damage consistency fit the safe mid-range cruiser plan.

Magazine HP

The magazine is the module a detonation comes from. Penetrating hits to it raise the detonation chance from 1% toward 30% as its HP is worn down, so a larger magazine pool rides out citadel hits longer before a detonation becomes likely.

Armor

Hull HP 23,000 → 25,500 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.

Section	Plates	HP cap	Threats	Tactic
Bow	20 mm primary (range 13–20 mm)	900 (4% of HP)	Overmatched by 305mm+ (Mikasa, Courbet)Angle bounces 283mm20 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)	13 mm primary (range 13–30 mm)	19,100 (75% of HP)	Overmatched by 203mm+ (Desert Falcon, Genova)Angle bounces 152mm13 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	30 mm primary (range 13–30 mm)	500 (2% of HP)	Overmatch not possible at T IVAngle bounces 410mm30 mm: HE pens from 203mm+	Mirror of bow. Same fast saturation.
Citadel	50 mm primary (range 16–50 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	7 mm primary (range 7–50 mm)	1,400 (5% 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	12,000 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 (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	7,700 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.
