Udaloi Build & Guide | WoWs Legends

Playstyle

Overview

Udaloi is a Tier VII Soviet torpedo-and-gun destroyer (7.6 km surface detection and 8 km torpedoes). She rewards contesting caps from concealment edges and trading detection windows for torpedo damage. Standout traits: best AA reach in T7 DDs (5.2 km) and best Repair Party duration in T7 DDs (28 s).

Positioning

Hold concealment edges around the contested cap until detection windows open, then peel out before the radar or spot timer matters. The torpedoes are the threat; smoke and stealth are how you survive long enough to drop another wave.

Potato Avoidance

Overstaying detection after a torpedo drop

The detection window is a hard timer; if you are still firing guns when concealment closes again, you have already taken more damage than the drop earned.

Signature Traits

Long-reach AA

5.2 km AA reach, best of T7 DDs.

Long heal window

28.0 s Repair Party duration, best of T7 DDs. Restores HP for longer per activation.

Long DCP window

10.0 s Damage Control duration, best of T7 DDs. Stays fire / flood immune longer per activation.

Top-tier AA

278.0 AA DPS, top decile of T7 DDs (median 170.0).

Easily spotted

7.58 km surface detect, worst of T7 DDs. Visible before you can react; position early.

Slow reload

6.8 s reload, bottom decile of T7 DDs. Salvos punish more, but cycle is slower than peers.

Acquisition

How to get Udaloi

Udaloi is available in the Generalist Destroyers branch of the U.S.S.R. Tech Tree for 18,000,000 credits after researching it in the branch. Known module upgrades cost up to 4,500,000 credits.

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 16,000 → 18,800 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.

Hull (midship)	16 mm	14,100 (75% of HP)	Overmatched by 283mm+ (Scharnhorst, Scharnhorst '43)Angle bounces 203mm16 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	20 mm primary (range 16–20 mm)	1,300 (7% of HP)	Overmatched by 305mm+ (Toulon, Cherbourg)Angle bounces 283mm20 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	19 mm primary (range 13–19 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 6–16 mm)	1,400 (7% 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	9,400 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 (37 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	5,600 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.
