Overview
Jervis is a Tier VI British smoke destroyer with 6 smoke charges on a short cooldown: the many smokes are the kit, setting up aggressive and defensive plays that one-smoke DDs cannot. Hold cap edges and trade gunfire from cover, then re-smoke before the next window closes. Standout traits: best big torpedo salvo in T6 DDs (10, 4th of 41) and best Sonar duration in T6 DDs (180 s, 2nd of 8). The trade is torpedo reload in T6 DDs (120 s, 39th of 41).
Positioning
Anchor near a smoke cycle on a contested cap and trade gunfire from inside the cloud. The smoke is your sustain tool; rotating mid-smoke wastes the cycle for the next contest. Your guns lose penetration at range, so aim AP at broadsides you can still citadel and put HE into superstructures and upper-hull sections, rather than the bow-in or belt armor your shells bounce and shatter on. Shooting from the cloud gives you away at 2.5 km, and a destroyer here is spotted at about 6.9 km, so you see it coming with roughly 4.4 km to spare. Vision is mutual: past the 2 km guaranteed ring you cannot see out either, and only your Sonar bubble (3.5 km) sees out; past that you are shooting at what a teammate holds lit. Enemy sonar (about 4.2 km) and radar (about 9 km) read straight in regardless. At 600 m the screen is wider than standard, so it can cover a teammate holding the same line as well as your own hull. Once the rudder is over she turns tightly for her cohort (590 m), so a committed turn costs less water than most of what she is fighting.
Potato Avoidance
Rotating mid-smoke
The smoke is a static firing position; if you leave it before the cycle ends, you give up the trade you set up and the next contest opens without a smoke to fall back on.
Signature Traits
10 tubes per side, best of T6 DDs. More torpedoes per launch: spread wide to cover a reposition, or tight for more hits on a thin target.
180 s Sonar duration, best of T6 DDs.
- Extra smoke charges · 6 Smoke
- Fast smoke cycle · 60 s
~2.1 s from a stop to 12 kt, top decile of T6 DDs. Rebuilds speed quickly after a turn or a stop, so it re-angles and repositions without staying a stationary target.
120 s torpedo reload, bottom decile of T6 DDs. Long wait between drops.
2.5 km AA reach, bottom decile of T6 DDs. Bombs and torpedoes drop before AA bites.

How far each mount can train, in degrees to either side of the mount's own facing. A rear turret with ±150° leaves a 60° blind wedge over the bow; one-sided arcs are wing mounts that cover a single side. The data does not say which way each mount faces, so the arcs are listed per mount without bow/stern angles.ƒ
180° − 154° (the most restricted aft-facing mount's arc) = 26° off bow; 180° − 140° (the most restricted forward-facing mount's arc) = 40° off stern. How far off the bow (or stern) the ship must angle before every main turret can fire: the widest blind wedge among the rear-facing (or forward-facing) mounts, from each mount's trainable arc.ƒ
In practice: the baseline curve for a standard destroyer -- at max range (10.7 km) shells land in an ellipse about 95 m wide and 57 m tall.

AP shell over-penetration splash radius; scales with shell mass. Wickes 102mm = 3, standard 152mm CL ~ 20, Iowa 406mm ~ 270, Yamato 460mm = 400, Incomparable 650mm = 550 (max). Larger value = bigger splash damage area when AP over-pens.ƒ
Initial: 43,000 × 0.333 = 14,333 → 44,300 × 0.333 = 14,767 (warhead alpha × saturation coefficient, stock → upgraded torpedo). Most targets only intersect one hull section, so a hit transfers about 1/3 of the warhead alpha (2/3 when the warhead blast >= 5000 and the burst reaches a second section). For this ship: . In battle, a hit on the torpedo belt deals the per-hit figure × (1 − the target's torpedo protection %), a bow or stern hit deals it in full, and a torpedo never counts as a citadel hit.ƒ
44,300 warhead alpha / 3 + 1,100 blast = 15,867. Warhead alpha / 3 plus the blast addend: the per-torpedo damage figure. The 'Maximum simulated damage' row above applies target geometry to the same warhead.ƒ
Per-torpedo module/blast damage parameter. Most torpedoes carry 500 to 2,000; ships announced by WG as dealing increased module damage carry 9,000 to 12,000, so their hits knock out engines, rudders, and turrets far more often. Comparative figure.ƒ
How long a target has to dodge after your torpedo is spotted at its detectability range (lower means less warning): . 2.6855 converts knots to m/s on the game clock. Base value; commander torpedo-concealment skills lower it further.ƒ
This torpedo carries a flooding-chance value of 2.65 per hit, shown as . Values above 100% are normal: in battle the base chance is scaled down by the target's torpedo protection (the Torp Reduction stat on its Survivability card) and any flood-resistance modifiers, so a value above 100% keeps flooding likely even through partial protection.ƒ

top speed / 4 + 4.9 = 36 / 4 + 4.9 = 13.9 kt. Base value; speed modifiers scale it.ƒ
Seconds from top speed to a dead stop after ordering full reverse: reverse power winds in over the reverse spool-up while water drag does most of the braking, using the ship's own reverse-power ratio. The full curve is on the acceleration chart. Full reverse stops about a quarter faster than a plain Stop order from top speed.ƒ
Speed below which the engine's built-in power boost applies in reverse.ƒ
Time to reach 90% of top speed (32.4 kt of 36.0 kt).ƒ
Time to reach 99% of top speed (35.6 kt of 36.0 kt). 99% rather than 100% because true top speed is asymptotic (thrust meets drag), so the last fraction of a knot is never quite gained.ƒ
With the rudder hard over the hull turns 8.1°/s, so a target drifts across the bow at that rate. Turret traverse minus hull turn: 10 − 8.1 = +1.9°/s, so the guns hold the target through the turn. Main Battery Mod. 2 (+20% traverse) and Mod. 3 (−15%) move this line.ƒ
Base value, no camouflage. With a Grade IV permanent camo (or any disposable camo): 6.93 km x 0.955 = 6.62 km. Camouflage does not change detectability by air.ƒ
Detectability by sea 6.93 km x 0.955 (Grade IV permanent camo or any disposable camo) = 6.62 km.ƒ
max(main battery range, sea detectability 6.93 km) = 10.66 km. Equal to the ship's main battery range (never below base detectability): firing makes you visible to everyone you can reach.ƒ
Air detectability 3.47 km + gun-firing bloom 2.4 km = 5.87 km. The bloom tracks main-battery caliber 120 mm × 0.020 = 2.4 km.ƒ

How wide your shells scatter at 10 km, from the same dispersion model as the max-range figure above. Picking a fixed range makes this number directly comparable from ship to ship: max-range dispersion makes a longer-range gun look worse even when it's tighter at any common range.

That runs from a 808 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77 because the game clock runs faster than real time.

Each hit on the target's torpedo belt is reduced by its torpedo protection %.AA defense
Only families that reach 2.5 km contribute at the outer edge of the AA bubble. In-game families: 20mm Oerlikon MK4 4x1 -> 54 DPS @ 2 km; 20mm Oerlikon MK V 2x2 -> 27 DPS @ 2 km; 2 pdr MkVII Quad 1x4 -> 39 DPS @ 2.5 km.@ 2.5 km: 39 from one family; @ 2 km: 54 + 27 + 39 = 120. Cumulative AA DPS at each family range threshold. Inner ranges stack the outer families, so a target closing the distance hits stronger AA bubbles as it crosses each band.54 + 27 + 39 = 120 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).54 × 2 + 27 × 2 + 39 × 2.5 = 260. 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.Ship Charts
Background
The J-class ships became the pioneers of the new generation of British destroyers. Their increased size enabled them to carry powerful artillery in new twin mounts.
Armor Beta
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.
Overmatched by 126+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.
Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 30%, fires burn 30s. Range-by-range in the Compare tool →

An AP citadel penetration deals the shell's full damage, the biggest single hit available; only over-penetrations are damped, to ×0.10. |

| Turret (module, per magazine) | separate HP pool, does not drain ship HP | 7,200 magazine HP | Turret knocked out | Per-turret powder-magazine HP, a separate pool that does not drain ship HP. As it is worn down the turret is likelier to be knocked out, and a smaller pool gets there 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.
