Overview

Lugdunum is a Tier VI European secondary battleship with top-decile secondary reach out to 6.5 km: the kit rewards closing inside secondary range and letting the auto-fire battery work alongside the mains, not holding mid-range AP lines. Standout traits: secondary dispersion (244.5 m) and top-decile heavy secondary DPM in T6 BBs (342,000).

Positioning

Push to within secondary range (~6.5 km) so the secondary battery starts contributing damage. A secondary BB at mid range is wasting half her kit; the geometry that pays out is close enough that the secondaries DPM peer BBs instead of the main battery alone. She is genuinely evasive in both phases of a turn, answering the helm in 12.8 s and carving a 700 m circle, so you can break a salvo and still be where you meant to go.

Potato Avoidance

Torpedo Boat Brawling

With no torpedoes you cannot trade back a fight fought inside enemy torpedo range. Hold the band where your guns and secondaries punish them while their fish still fall short, and lean on armor and volume of fire instead of closing the last few kilometers into a spread you have no answer for.

No torpedo backup

A brawler with no torpedoes: every trade is guns and secondaries. The sweet spot is inside secondary range but outside easy torpedo range -- close enough that the auto-fire battery works, not so close that a destroyer or torpedo cruiser lands a salvo you can't answer.

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.

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 duration60 s

Fire damage

Each fire ticks 0.3% of max HP per second for the full 60 s, so one unattended fire burns 18% of the pool (9,612 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 0.5% of max HP per second for the 40 s duration, so one unattended flood costs 20% of the pool (10,680 HP on this ship). Verified against measured flood ticks in replay data.

0.5% 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.

16%

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.

26,700

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.

16,000

Effective HP

Base 53,400 HP plus everything Repair Party can restore: 0.5%/s x 28 s = 7,476 HP per charge, x3 charges = 22,428 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.

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.

4x ±138°

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.

Bursts

Each ~2 s wave fires 2 quick salvos of 3 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between waves - up to 7 clouds per wave × 210 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.

2 salvos × 3 clouds + 1 outer

Cloud damage

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

210

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.

75%

Wave rate

A flak wave spawns roughly every 2 s - timed frame-by-frame from gameplay footage and consistent across ships.

every ~2 s

Fired by

Flak keeps firing while at least one secondary battery mount is operational - even losing every other AA mount does not stop it.

Secondary battery

Flak zone

The activation band: flak fires while attacking planes are inside it. Clouds are placed ahead of the planes' path, so bursts can land short of 2.5 km or past 5.2 km - once planes get inside the band, new waves stop. AA range bonuses push the outer edge out; the 2.5 km inner edge does not move.

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.

39.6 s

8.8 kt

Acceleration 0-90%

Time to reach 90% of top speed (24.3 kt of 27 kt), from our in-house acceleration model.

33.8 s

Acceleration 0-99%

Time to reach 99% of top speed (26.7 kt of 27 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.

53.9 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{27.0 \cdot 0.5144}{700} = 1.14 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{3.5}{1.14} = 3.1 \times

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{15930}{30} \cdot \frac{12 - 2.2}{1000} + 2.2) \cdot 30 = 222.1 m$

Shell scatter width @ 5 km115 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 km164 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 km213 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.

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 222.1 \cdot 0.6 = 133.3 m$

Shell scatter height @ 10 km86.2 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  $delim \cdot R_{m a x} = 0.5 \cdot 15930 = 7965$  m, and  $radiusOnMax = 0.6$  at 15930 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7965}{15930 - 7965} = 0.5255$ , so  $σ_{V} = σ_{H} \cdot k = 164 \cdot 0.5255 = 86.2 m$ .

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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.21 \cdot {0.34}^{2}}{8 \cdot 380} = 2.51 \times 10^{- 5}$ . That runs from a 780 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 flight time @ 10 km5.02 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.37 \cdot {0.34}^{2}}{8 \cdot 431.8} = 3.89 \times 10^{- 5}$ . That runs from a 921 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 penetration57 mm

57 mm ≈ 340 mm caliber / 6 (standard HE penetration ratio).

AP overmatch23 mm

floor(340 mm caliber / 14.3) = 23 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius50

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 alpha16

All 16 barrels bear on the broadside.

Turret turn time51.4 s

180 degrees / 3.5 deg/s traverse speed = 51.4 s.

HE full-salvo alpha65,600

4,100 HE damage x 16 broadside guns = 65,600.

AP full-salvo alpha124,800

7,800 AP damage x 16 broadside guns = 124,800.

HE DPM157,440

65,600 HE full-salvo alpha x 60 / 25 s base reload = 157,440.

AP DPM299,520

124,800 AP full-salvo alpha x 60 / 25 s base reload = 299,520.

Shells/min38.4

16 broadside guns x 60 / 25 s base reload = 38.4.

Fires/min9.22

38.4 shells/min x 24% fire chance = 9.22.

AA defense

AA DPS at max range76

Only families that reach 5.2 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors Mk3 16x1 -> 191 DPS @ 3.5 km; 40mm Bofors 4x4 -> 48 DPS @ 3.5 km; 20mm Oerlikon MK20 Twin 8x2 -> 53 DPS @ 2 km; 20mm Oerlikon MK4 12x1 -> 79 DPS @ 2 km; 130 45 Mle 1932 quad 4x4 -> 38 DPS @ 5.2 km; 130 45 Mle 1932 twin 4x2 -> 38 DPS @ 5.2 km.

Maximum AA range5.2 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 range76 DPS @ 5.2 km, 315 DPS @ 3.5 km, 447 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-blank447

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

AA threat index1496

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 typeImproved (40%, German battlecruiser type)

Max dispersion = range (km) × 33 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.

Max secondary dispersion @ 6.5 km244.5 m

6.5 km × 33 + 30 = 244.5 m.

Secondary dispersion @ 5 km195 m

Same per-type line evaluated at a fixed 5 km: 5 km × 33 + 30 = 195 m.

Secondary battery firepower

Secondary DPM (per side)342,000

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: 4×4 130 mm (8/side) × 60/4 × 1900 = 228,000 + 4×2 130 mm (4/side) × 60/4 × 1900 = 114,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha1900

Maximum HE damage per shell across secondary HE families. Best on this ship: 1900 from the 130 mm family.

Max HE fire chance9%

Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 9% from the 130 mm family.

Max HE pen22 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: 22 mm from the 130 mm family.

Armor Beta

Hull HP 53,400, 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 & stern26 mm

Overmatched by 80+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel300 mm

Citadels come from a flat broadside at close range; held past ~30° of angle, AP shatters or bounces.

Farming12 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 30%, fires burn 60s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	26 mm primary (range 12–180 mm)	1,700 (3% of HP)	Overmatched by 380mm+ AP (Bayern, Richelieu)Angle bounces 356mm26 mm: HE pens from 203mm+	Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.

Stern	30 mm primary (range 12–200 mm)	1,900 (4% of HP)	Overmatch not possible in its bracketAngle bounces 410mm30 mm: HE pens from 203mm+	Mirror of bow. Same fast saturation.
Citadel	300 mm primary (range 22–190 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	12 mm primary (range 12–350 mm)	2,300 (4% 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	26,700 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 (130 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	16,000 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.
