Playstyle

Overview

Shiratsuyu is a Tier VI Japanese stealth-leaning destroyer with strong surface detection (6.8 km). The kit opens detection windows most peer DDs cannot match, so her value is contesting caps from concealment edges where the detection band holds. Standout traits: top-decile AP shell velocity in T6 DDs (915) and top-decile flat HE shells in T6 DDs (915).

Positioning

Hold concealment edges on the contested cap at 6.8 km detection. The band opens windows for unspotted torpedo drops and clean repositions; lean into the gaps your peer DDs cannot read, and back out before detection closes.

Potato Avoidance

Burning the 6.8 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

Flat AP shells

915.0 m/s AP muzzle velocity, top decile of T6 DDs. Flatter trajectory, less lead, harder to dodge.

Flat HE shells

915.0 m/s HE muzzle velocity, top decile of T6 DDs. Flatter trajectory, easier to land at range.

Fast acceleration

~9.5 s to max forward speed, top decile of T6 DDs. Rebuilds speed quickly after a turn or stop. (Acceleration decode is validated in-game but not yet confirmed across every ship.)

Visible torps

1.8 km torpedo detect, worst of T6 DDs. Easy to dodge if targets are looking.

Fragile HP pool

12800.0 HP, bottom decile of T6 DDs. Trade hits sparingly.

Acquisition

How to get Shiratsuyu

Shiratsuyu is available in the Gunboat Destroyers branch of the Japan Tech Tree for 9,000,000 credits after researching it in the branch. Known module upgrades cost up to 2,250,000 credits.

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 11,600 → 12,800 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	16 mm primary (range 15–16 mm)	1,800 (14% of HP)	Overmatched by 283mm+ (Graf Spee, Scharnhorst)Angle bounces 203mm16 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.
Stern	16 mm primary (range 13–16 mm)	1,500 (12% of HP)	Overmatched by 283mm+ (Graf Spee, Scharnhorst)Angle bounces 203mm16 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	16 mm primary (range 10–16 mm)	≈ 165,500 (effectively no cap)	Citadel pen ×0.50 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 (×0.50 direct pen, ×0.10 over-pen).
Superstructure	6 mm primary (range 6–13 mm)	600 (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	6,400 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 (25 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	3,800 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.

Holiday Update: Chilling With the Beasts

Main battery reload time decreased from 7.2s to 5s.
We found that Shiratsuyu does suffer in destroyer duels that don't end in torpedo carnage, but the main concern was that her ability to set fires was a little lower than we would have liked it to be, hence this buff.
