Overview

Neptune is a Tier VIII British AP-only cruiser with cohort-best AP DPM (576,000): she carries no HE shells at all, so every salvo is AP into broadsides or wasted. The hull is fragile, so the kit is fragile-spammer chasing soft targets and dodging in open water rather than trading punches. She also packs the super-heal, but the kit is offense first, sustain second. Surveillance Radar (9.4 km, 35 s active, every 180 s) is the cap-control consumable on top, so she sets fights as well as winning them. AA (707 AA DPS at 6 km, +100% Defensive AA flak burst) ranks 3 of 35 in T8 CAs: heavy enough to make a careless strike expensive, though not the umbrella that shuts a carrier out of her grid. Standout traits: best AP always-pen window in T8 CAs (60°) and best AP guaranteed-ricochet angle in T8 CAs (75°).

Positioning

Sit 12-15 km on a flank that gives you firing arcs into rotated cruisers and exposed BB broadsides. The hull is fragile; ration trades to ones that pay AP citadels back, and lean on speed and consumables to dodge focus when it comes. Open water is fine when the closest threat is far enough that the salvo timing favors you. Your AP loses penetration at range, so aim at superstructures or pen-able hull armor, not the bow-in or belt armor it bounces and shatters on. Shooting from the cloud gives you away at 5.8 km, and a destroyer here is spotted at about 7 km, so you see it coming with roughly 1.3 km to spare. Vision is mutual: past the 2 km guaranteed ring you cannot see out either, but your own Radar (9.4 km) reads through it, so you can find targets instead of borrowing them. Enemy sonar (about 4.7 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.

Potato Avoidance

Passing up destroyer shots because the AP over-pens

Even an over-pen is guaranteed chip damage that wears a DD down and denies its caps and torpedo runs, so keep guns on any destroyer you can see. Save the citadel salvos for broadside cruisers and BB sides, but never hold fire on a spotted DD. A skipped salvo is 4 s of nothing, and over-pens you did take would have been damage the destroyer cannot heal back.

Signature Traits

Surveillance Radar

9.45 km range, 35 s duration. Detects all enemy ships within a fixed radius regardless of line-of-sight. Controls caps and punishes smoke-firing DDs.

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.

40%

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 (4,041 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 (4,490 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.

13%

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.

22,500

Steering gear HP

Durability of the steering gears. As this pool drops, hits are likelier to jam the rudder; unlike most modules the steering can be knocked out and repaired but is never permanently destroyed.

13,500

Effective HP

Base 44,900 HP plus everything Repair Party can restore: 2%/s x 20 s = 17,960 HP per charge, x2 charges = 35,920 HP. Ceiling, not a prediction: a charge only restores damage actually taken, and only the regeneratable share of it. Across 1,826 players in our replay corpus the median ship realized about half of this, mostly because half the charges go unspent — when Repair Party IS pressed it returns ~97% of the per-charge figure above.

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.

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 = 47, 000 \cdot 0.333 = 15, 667

≈ 15,667

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 detectability1.3 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{1.3 km}{62 kt \times 2.6855} = 7.8 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.

7.8 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 2.82 per hit, shown as

2.82 \times 100 = 282 %

. 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.

Bursts

Each ~2 s wave fires 3 quick salvos of 2 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between waves - up to 7 clouds per wave × 250 damage each. Planes that fly into a cloud take its damage; clouds dissipate before the next wave lands. Defensive AA Fire, where fitted, multiplies the salvo repeats within each wave.

Cloud damage

Damage a plane takes for flying into one flak cloud, before any reductions.

Cloud spawn chance

Each cloud in the pattern rolls this chance to spawn, so waves average fewer clouds than the maximum. Often called flak 'hit chance', but spawned clouds always damage planes that fly into them - the roll is on spawning.

Acceleration 0-99%

Time to reach 99% of top speed (33.2 kt of 33.5 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.

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{33.5 \cdot 0.5144}{790} = 1.25 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{10}{1.25} = 8.0 \times

. Below 5 the turrets drag in a turning fight; 25+ keeps up with any rudder.

Main battery formulas

Shell Grouping (σ)2.05

Max Horiz Disp139.6 m at 15.5 km

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{15450.6}{30} \cdot \frac{8 - 1.1}{1000} + 1.1) \cdot 30 = 139.6 m$

Shell scatter width @ 5 km67.5 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 km102 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.

Shell scatter width @ 15 km136.5 m

Horizontal scatter at a fixed 15 km, from the same verified dispersion model - the long-range anchor. Only shown when the ship's guns reach 15 km.

Max Vert Disp83.8 m at 15.5 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 139.6 \cdot 0.6 = 83.8 m$

Shell scatter height @ 10 km54 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  $delim \cdot R_{m a x} = 0.5 \cdot 15450.6 = 7725$  m, and  $radiusOnMax = 0.6$  at 15450.6 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7725}{15450.6 - 7725} = 0.5294$ , so  $σ_{V} = σ_{H} \cdot k = 102 \cdot 0.5294 = 54 m$ .

Med Horiz Disp40.9 m at 15.5 km

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 139.6 \cdot \frac{0.6}{2.05} = 40.9 m$

Med Vert Disp24.5 m at 15.5 km

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 83.8 \cdot \frac{0.6}{2.05} = 24.5 m$

Dispersion familyCruiser Disp.

Standard cruiser dispersion baseline.

AP Pen Close320 mm point-blank

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2672 \cdot {58.85}^{0.69} \cdot {0.152}^{- 1.07} \cdot 768^{1.38} = 320 mm$ . Matches the in-game spec card.

AP Pen Far97.3 mm at 15.5 km

Same formula at the ship's max firing range (15.5 km), where the shell has slowed to 324 m/s:  $P = 10^{- 7} \cdot 2672 \cdot {58.85}^{0.69} \cdot {0.152}^{- 1.07} \cdot 324^{1.38} = 97.3 mm$ .

AP pen 5 km204 mm

AP penetration at a fixed 5 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 10 km134 mm

AP penetration at a fixed 10 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 15 km99 mm

AP penetration at a fixed 15 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP flight time @ 10 km6.65 s

How long an AP 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3475 \cdot {0.152}^{2}}{8 \cdot 58.85} = 5.36 \times 10^{- 5}$ . That runs from a 768 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.

AP overmatch10 mm

floor(152 mm caliber / 14.3) = 10 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius20

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.

Broadside guns used for alpha12

All 12 barrels bear on the broadside.

Turret turn time18 s

180 degrees / 10 deg/s traverse speed = 18 s.

AP full-salvo alpha38,400

3,200 AP damage x 12 broadside guns = 38,400.

AP DPMInitial: 512,000 → 576,000

Zero upgrades: 38,400 AP full-salvo alpha x 60 / 4.5 s base reload = 512,000. All upgrades (Main Battery Mod. 3 = -10% reload): 38,400 AP full-salvo alpha x 60 / 4 s all-upgrades reload = 576,000.

Shells/minInitial: 160 → 180

Zero upgrades: 12 broadside guns x 60 / 4.5 s base reload = 160. All upgrades (Main Battery Mod. 3 = -10% reload): 12 broadside guns x 60 / 4 s all-upgrades reload = 180.

Torpedoes

Torpedo detectability1.3 km

Estimated torpedo reaction time7.8 s

detectability / (speed kt x 2.6855 game-speed factor, m/s per knot, calibrated from in-game measurement; the community's traditional 2.6 reads about 3% slower).

Torpedo speed62 kt

Travel time to max range60 s

range / (speed kt x 2.6855 game-speed factor, m/s per knot, calibrated from in-game measurement).

Torpedo module damage1,100

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.

Tube count16

4 launchers x 4 tubes.

Per-side salvo8 torpedoes

tube count / 2 (symmetric port/starboard launcher layout; common on cruisers and battleships with deck torpedoes).

Full-salvo damage250,672

All tubes hitting one target: tubes x per-torpedo simulated damage = 16 x 15,667 = 250,672.

Per-side salvo damage125,336

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 8 x 15,667 = 125,336.

AA defense

AA DPS at max range88

Only families that reach 6 km contribute at the outer edge of the AA bubble. In-game families: STAAG MarkV 10x2 -> 369 DPS @ 3.5 km; 20mm Oerlikon MK V 14x2 -> 140 DPS @ 2 km; 4 5in45 MK 5 6x2 -> 110 DPS @ 5 km; Far AA (?) -> 88 DPS @ 6 km.

Maximum AA range6 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 @ 6 km, 198 DPS @ 5 km, 567 DPS @ 3.5 km, 707 DPS @ 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-blank707

Sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index2650

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.

Near aura range2 km

Secondary battery dispersion

Secondary dispersion typeStandard

Max dispersion = range (km) × 57 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.

Max secondary dispersion @ 5 km315 m

5 km × 57 + 30 = 315 m.

Secondary battery firepower

Secondary DPM (per side)192,000

Sum across all secondary families of (per-side barrels × 60 / reload_s × alpha), where per-side barrels = mounts × barrels-per-mount / 2 (the guns that bear on one broadside target). Per-family: 6×2 114 mm (6/side) × 60/3 × 1600 = 192,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha1600

Maximum HE damage per shell across secondary HE families. Best on this ship: 1600 from the 114 mm family.

Max HE fire chance7%

Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 7% from the 114 mm family.

Max HE pen19 mm

Maximum HE armor penetration across secondary HE families (caliber × 1/6 for most nations; 1/4 for German/UK BBs). Shells whose pen falls under a plate's armor thickness shatter for 0 hull damage though fire chance still applies. Best on this ship: 19 mm from the 114 mm family.

Armor Beta

Hull HP 39,900 → 44,900 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.

Bow & stern16 mm

Overmatched by 139+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel102 mm

Thin belt: battleship AP citadels straight through it broadside. Rely on angle, speed and concealment, never sit flat.

Farming13 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 40%, fires burn 30s. Range-by-range in the Compare tool →

Citadel	102 mm primary (range 16–102 mm)	≈ 165,500 (effectively 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	13 mm primary (range 13–102 mm)	3,800 (8% 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	22,500 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.
Secondary mount (114 mm mount)	separate HP pool, does not drain ship HP	800 per-mount HP	Destroyed at 0 HP	Per-mount HP for the heaviest secondary on this ship. A mount destroyed at 0 HP is out for the rest of the battle; DCP does not repair destroyed mounts. Smaller (lighter-caliber) secondaries typically share the same HP value.
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	13,500 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.
