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. Both shells run cohort-strong (top-decile AP at 299,520 AP DPM and cohort-best HE at 157,440 HE DPM), making her a dual-threat gunship: keep AP up against broadsides and citadels, and switch to HE against bow-in ships, superstructures, and the thin or angled targets AP over-penetrates or bounces off. Standout traits: best flat HE shells in T6 BBs (921) and best AA reach in T6 BBs (5.2 km).
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.
The secondary battery is half the kit, so a mid-range secondary BB is leaving damage on the table every minute; commit to the brawl angle or play a different ship.
5.2 km AA reach, best of T6 BBs.
342000.0 secondary DPM per side, top decile of T6 BBs. Per-side barrels × shots/min × alpha across every secondary family; real damage scales with hit rate against the target.
40.0 s Repair Party reload, top decile of T6 BBs. Heals up more often than peers.

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model: $\sigma_H = \left(\dfrac{R}{30}\cdot\dfrac{\text{idealRadius}-\text{minRadius}}{\text{idealDistance}} + \text{minRadius}\right)\cdot 30$ $= \left(\dfrac{15930}{30}\cdot\dfrac{12-2.2}{1000} + 2.2\right)\cdot 30 = 222.1\,\text{m}$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.Vertical dispersion ellipse height at max range: $\sigma_V = \sigma_H \cdot \text{radiusOnMax}$ $= 222.1 \cdot 0.6 = 133.3\,\text{m}$How tall the same scatter ellipse is at 10 km. Comparable from ship to ship for the same reason as the width value above.50%-hit horizontal radius: $\sigma_{H,50} = \sigma_H \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 222.1 \cdot 0.369\;(\sigma = 1.6) = 82\,\text{m}$50%-hit vertical radius: $\sigma_{V,50} = \sigma_V \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 133.3 \cdot 0.369\;(\sigma = 1.6) = 49.2\,\text{m}$Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity: $P = 10^{-7}\cdot K \cdot m^{0.69} \cdot d^{-1.07} \cdot v_0^{1.38}$ $= 10^{-7}\cdot 2408 \cdot 380^{0.69} \cdot 0.34^{-1.07} \cdot 780^{1.38} = 450.9\,\text{mm}$. Matches the in-game spec card.Same formula at the ship's max firing range (19.9 km), where the shell has slowed to 458.6 m/s: $P = 10^{-7}\cdot 2408 \cdot 380^{0.69} \cdot 0.34^{-1.07} \cdot 458.6^{1.38} = 216.7\,\text{mm}$.57 mm ≈ 340 mm caliber / 6 (standard HE penetration ratio).floor(340 mm caliber / 14.3) = 23 mm (AP auto-penetrates plating this thick or less).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.All 16 barrels bear on the broadside.180 degrees / 3.5 deg/s traverse speed = 51.4 s.4,100 HE damage x 16 broadside guns = 65,600.7,800 AP damage x 16 broadside guns = 124,800.65,600 HE full-salvo alpha x 60 / 25 s base reload = 157,440.124,800 AP full-salvo alpha x 60 / 25 s base reload = 299,520.16 broadside guns x 60 / 25 s base reload = 38.4.38.4 shells/min x 24% fire chance = 9.22.Sum across every AA aura on this ship of (aura.continuous_damage x 3.5 x aura.hit_probability). Here: (91×3.5×0.75) + (54×3.5×0.7) + (29×3.5×0.75) = 447. Covers AA-only mounts plus dual-purpose secondaries (Bismarck 105mm, USN 5"/38 cruiser secondaries) and dual-purpose main batteries (Sumner-class 5"/38, Akizuki-line 100mm). Formula validated against in-game captures on California, Sumner, Manfred von Richthofen, Dante Alighieri (exact) and within +/-17% on the remaining verified ships.Longest-reaching aura across AA-only + dual-purpose auras.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.Max dispersion = range (km) × 33 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.6.5 km × 33 + 30 = 244.5 m.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).Maximum HE damage per shell across secondary HE families.

Best on this ship: 9% from the 130 mm family.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.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.
Overmatched by 79+ guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.
Citadels come from a flat broadside at close range; held past ~30° of angle, AP shatters or bounces.
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 ballistics tool →
| Section | Plates | HP cap | Threats | Tactic |

| 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 | 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. |
| 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.
