Jervis Build & Guide | WoWs Legends

Playstyle

Overview

Jervis is a Tier VI British stealth-leaning destroyer with strong surface detection (6.9 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: best smoke duration in T6 DDs (20 s) and top-decile high-arc AP shells in T6 DDs (45.2°).

Positioning

Hold concealment edges on the contested cap at 6.9 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. Her high-arc gun shells lob over island cover, so you can rain HE on broadsides from positions where flat-trajectory DDs have no firing solution.

Potato Avoidance

Burning the 6.9 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

Long-burning smoke

20.0 s Smoke Generator duration, best of T6 DDs. Holds the smoke shield longer.

Long-duration sonar

180.0 s Sonar duration, best of T6 DDs.

High-arc HE shells

45.2° HE impact angle at max range, top decile of T6 DDs. Lobs over cover.

High-arc AP shells

45.2° impact angle at max range, top decile of T6 DDs. Lobs over island cover.

Slow torp reload

120.0 s torpedo reload, bottom decile of T6 DDs. Long wait between drops.

Short AA reach

2.5 km AA reach, bottom quartile of T6 DDs. Drops bombs and rockets land before AA bites.

Acquisition

How to get Jervis

Jervis is available in the Dueling Destroyers branch of the U.K. Tech Tree for 9,000,000 credits after researching it in the branch. Known module upgrades cost up to 2,250,000 credits.

Ariadne M. Davis, Grotmaz Smart, and Phillip Vian are useful British destroyer commander directions. Inspirations usually start with concealment, then add HP, torpedo reload, gun performance, or speed depending on whether you want safer scouting or harder cap fights.

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.

Armor

Hull HP 11,800 → 14,300 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)	2,100 (15% 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.
Hull (midship)	16 mm	10,700 (75% of HP)	Overmatched by 283mm+ (Graf Spee, Scharnhorst)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	16 mm primary (range 13–16 mm)	1,300 (9% 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	13 mm primary (range 13–16 mm)	900 (6% 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	7,200 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	4,300 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.
