Overview

Grom is a Tier VI European torpedo destroyer reaching 7.5 km. The torpedoes travel at 72 kt, so target reaction time is short - but WG builds her as a gun-and-torpedo hybrid: four hard-hitting HE guns provide the steady damage while the quick, short-lane torpedoes punish anyone who closes. Standout traits: top-decile quick acceleration in T6 DDs (8 s).

Positioning

Sit at the edge of a contested cap from concealment and cycle torpedo waves into lanes the enemy has to use - 7.5 km reach at 72 kt closes the gap fast, though at about 8.3 s of warning the wall works by denying lanes rather than by catching anyone unaware. Drop on probable lanes from cover, stay unspotted between waves, and let the wall do the work. With only HE, aim at superstructures and upper-hull sections where it does full damage instead of shattering on heavy belt armor.

Potato Avoidance

Holding 7.5-km torpedoes for a perfect shot

The kit pays out by saturating lanes, not by waiting for guaranteed broadsides; missed waves still force rotations and protect your team's flank. Idle torpedo tubes are the worst output state.

Signature Traits

Improved HE penetration

HE pen at the 1/4 caliber ratio instead of the standard 1/6. HE-spam is a real damage option here, not just a fire-starter, shared by 5/41 T6 DDs.

Deep-water torpedoes

Torps IGNORE the Destroyer class (deep-water mechanic); they pass under DDs and cannot hit them. Aim ONLY at battleships, carriers, and most cruisers; every torp fired at a DD is wasted, shared by 3/41 T6 DDs.

Surveillance Radar

7.5 km range, 15 s duration. Detects all enemy ships within a fixed radius regardless of line-of-sight. A short scan - long enough to break a smoke camp or call a target for the team, not to hold a cap.

Engine Boost

+5% speed (about +1.9 kt), 100 s duration. Engine Boost consumable gives a small speed nudge - useful for closing a gap or steadying a torpedo run, not for running anything down.

Hull dimensions

Length x beam at the waterline, with the hull's draft where the client carries one. Ships whose client entry holds only the 260 x 20 m placeholder use a curated real-world figure instead, and any ship we have no trustworthy size for omits this row rather than print the placeholder. Length matters when dodging torpedoes; beam and draft shape how hard the ship is to hit.

Fire resistance

Does not reduce the damage a burning fire does per second: replay-measured burn ticks run at the full rate on every ship. By elimination it lowers how often hits set you on fire; ignition-rate replay data is consistent with that but too confounded by attacker mix to measure the reduction directly.

30%

Fire duration30 s

Fire damage

Each fire ticks 0.3% of max HP per second for the full 30 s, so one unattended fire burns 9% of the pool (1,395 HP on this ship). 4 fire points can burn at once. Verified against measured burn ticks in replay data.

0.3% of HP per second

Flood duration40 s

Flood damage

A flood ticks 0.25% of max HP per second for the 40 s duration, so one unattended flood costs 10% of the pool (1,550 HP on this ship). Verified against measured flood ticks in replay data.

0.25% of HP per second

Torp Reduction

Reduces torpedo hit damage. Replay data shows no effect on floods: flood ticks run at the full rate and flood frequency does not decline with protection.

Magazine HP

Per-turret powder-magazine HP, a separate pool from the ship's. Penetrating hits wear it down and the turret is likelier to be knocked out as it falls, so a larger pool keeps the guns firing through punishment that silences a peer's.

Turret traverse arcs

How far each mount can train, in degrees to either side of the mount's own facing, read from in-game data. 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.

±150°, ±147°

Guns to bear

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. Mount facing is inferred from turret stations and verified against known layouts, including Izumo's aft-facing forward turret.

Maximum simulated damage

Estimate of WG's in-game value; matches the in-game port screen within ±5%. Saturation: most targets only intersect one hull section, so the sim transfers ~1/3 of the warhead alpha (2/3 when the warhead blast >= 5000 and the burst reaches a second section). For this ship:

D_{sim} = α \cdot c = 67, 100 \cdot 0.333 = 22, 367

≈ 22,367

Maximum damage (ammunition)

The ammunition card's 'Maximum Damage' stat, exact: warhead alpha / 3 plus the blast addend. This is the per-torpedo number most references quote; the 'Maximum simulated damage' row above is WG's separate geometry-sim stat from the launcher spec panel.

Torpedo detectability1.1 km

Reaction time

How long a target has to dodge after your torpedo is spotted at its detectability range (lower means less warning):

t_{react} = \frac{1.1 km}{67 kt \times 2.6855} = 6.1 s

. The 2.6855 m/s-per-knot game-speed factor is calibrated from in-game measurement; the community's traditional 2.6 reads about 3% slower. Base value; commander torpedo-concealment skills lower it further. Community torpedo-reaction calculator by u/LorenDovah and u/The_ColorOutofSpace.

6.1 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 3.55 per hit, shown as

3.55 \times 100 = 355 %

. Torpedo flood 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. Not shown on the in-game port screen.

14.5 kt

Crash stop

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. Same community-model simulation as the acceleration times, using the ship's own reverse-power ratio from in-game data. The full curve is on the acceleration chart.

17 s

Engine boost threshold (reverse)

Speed below which the engine's built-in power boost applies in reverse. Matches the in-game maneuverability card's reverse threshold (Vampire II reads 10.5 here and the card shows 11; the card rounds half up).

14.4 kt

Acceleration 0-90%

Time to reach 90% of top speed (34.6 kt of 38.5 kt), from our in-house acceleration model.

7.5 s

Acceleration 0-99%

Time to reach 99% of top speed (38.1 kt of 38.5 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.

8.8 s

Traverse-to-turn ratio

How many degrees the turret can swing for each degree the hull turns. Turn rate

ω_{hull} = \frac{180}{π} \cdot \frac{V_{max} (m/s)}{R_{turn}} = \frac{180}{π} \cdot \frac{38.5 \cdot 0.5144}{610} = 1.86 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{12}{1.86} = 6.5 \times

Max Horiz Disp95 m at 10.7 km

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{10670}{30} \cdot \frac{8 - 0.5}{1000} + 0.5) \cdot 30 = 95 m$

Shell scatter width @ 5 km52.5 m

Horizontal scatter at a fixed 5 km, from the same verified dispersion model as the rows below - a knife-fight-range anchor comparable across ships.

Shell scatter width @ 10 km90 m

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. The interactive Dispersion tab on the Charts card plots the full curve from 0 to max range.

Max Vert Disp57 m at 10.7 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 95 \cdot 0.6 = 57 m$

Shell scatter height @ 10 km52.9 m

How tall the same scatter ellipse is at 10 km. Comparable from ship to ship for the same reason as the width value above. The height/width ratio is a piecewise-linear curve through three points from the ship's own dispersion data:  $radiusOnZero = 0.2$  at 0 m,  $radiusOnDelim = 0.5$  at  $delim \cdot R_{m a x} = 0.5 \cdot 10670 = 5335$  m, and  $radiusOnMax = 0.6$  at 10670 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 5335}{10670 - 5335} = 0.5874$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5874 = 52.9 m$ .

Med Horiz Disp28.5 m at 10.7 km

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 95 \cdot \frac{0.6}{2} = 28.5 m$

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 57 \cdot \frac{0.6}{2} = 17.1 m$

HE flight time @ 10 km6.54 s

How long an HE shell takes to reach a target at a fixed 10 km, from the same numerically integrated trajectory the Charts card plots. The shell slows under quadratic air drag,  $a_{drag} = k ρ v^{2}$ , where  $ρ$  is air density from a standard-atmosphere profile and  $k$  bundles the shell's drag coefficient, caliber and mass:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3177 \cdot {0.12}^{2}}{8 \cdot 24} = 7.49 \times 10^{- 5}$ . That runs from a 900 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77: the game clock runs faster than real time, and that factor was measured against stopwatch runs in the Training Room. Lower is better, since a faster shell is harder to dodge and needs less lead.

HE penetration30 mm

30 mm ≈ 120 mm caliber / 4 (improved HE penetration: German BBs, Yamato-class, and a handful of others).

Improved HE PenYes

This ship's HE shells use a 1/4 (~0.25) caliber-to-pen ratio instead of the standard 1/6 (~0.167) - 0.25 in this case. Lets HE pen ~30mm armor instead of ~20mm. Hits every German cruiser (150mm CL, 203mm CA) and BB (350mm+), British heavy cruisers / Lion / Nelson, a handful of other premiums.

Per-torpedo module/blast damage parameter from in-game data. 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; the exact module-HP conversion is not published.

AA defense

AA DPS at max range88

Only families that reach 3.5 km contribute at the outer edge of the AA bubble. In-game families: 40mm 56 Bofors N3 2x2 -> 88 DPS @ 3.5 km; 13mm Hotchkiss wz30 4x2 -> 43 DPS @ 1.2 km.

Maximum AA range3.5 km

Longest-reaching family on the in-game AA card. Base AirDefense aura max range is 3.5 km; dual-purpose mount auras extend it.

AA DPS layered by range88 DPS @ 3.5 km, 131 DPS @ 1.2 km

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.

AA DPS at point-blank131

Sum of every family's average DPS, achievable only inside the closest-range family (1.2 km).

AA threat index360

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.

Citadel	16 mm primary (range 10–16 mm)	no cap	Citadel pen: full damageOver-pen: ×0.10 damage	Effectively no cap; citadel pool sits at ~165k HP on every ship. An AP citadel penetration deals the shell's full damage, the biggest single hit available; only over-penetrations are damped, to ×0.10.
Superstructure	10 mm primary (range 10–16 mm)	no cap	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).

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.
