Overview

Jean Bart is a Tier VII French fast battleship at 30 kn with Engine Boost on the consumable slot. Mobility lets her rotate flanks battleship-fast and pick fights where her guns get the first salvo. Standout traits: top-decile heavy citadel belt in T7 BBs (405 mm) and top-decile burny secondaries in T7 BBs (12).

Positioning

Anchor a flank at 14-17 km with bow toward the closest threat, then use the speed advantage at 30 kn to rotate to the cap that needs a second battleship rather than the one your team already has. Mobility means you can pick which fight you are in; do not waste it by holding center the whole match.

Potato Avoidance

Using the 30-kn speed to push rather than to rotate

The mobility advantage is about picking which cap fight you arrive at, not about leading the brawl line; a fast BB that overextends loses HP that the kit cannot trade back.

Signature Traits

Engine Boost

+8% speed, 180 s duration. Engine Boost consumable temporarily raises top speed. Mobility on demand to reposition, chase a kill, or break contact, uncommon in T7 BBs.

ELITE ARMOR
  • Heavy citadel belt · 405.0 mm
  • Bow-tanker
  • Heavy belt
Burny secondaries

12.0% best HE fire chance per secondary shell (before target resistance), top decile of T7 BBs. Stacks fires faster than peers in a brawl.

Wide dispersion

237.3 m max horizontal dispersion, bottom decile of T7 BBs. Long-range salvos are noticeably wider than peers'.

Main battery formulas

Shell Grouping (σ)1.8
Max Horiz Disp237.3 m
Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model: $\sigma_H = \left(\dfrac{R}{30}\cdot\dfrac{\text{idealRadius}-\text{minRadius}}{\text{idealDistance}} + \text{minRadius}\right)\cdot 30$ $= \left(\dfrac{17482}{30}\cdot\dfrac{12-2.2}{1000} + 2.2\right)\cdot 30 = 237.3\,\text{m}$
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.
Max Vert Disp142.4 m
Vertical dispersion ellipse height at max range: $\sigma_V = \sigma_H \cdot \text{radiusOnMax}$ $= 237.3 \cdot 0.6 = 142.4\,\text{m}$
Shell scatter height @ 10 km84.4 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.
Med Horiz Disp81.6 m
50%-hit horizontal radius: $\sigma_{H,50} = \sigma_H \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 237.3 \cdot 0.344\;(\sigma = 1.8) = 81.6\,\text{m}$
Med Vert Disp49 m
50%-hit vertical radius: $\sigma_{V,50} = \sigma_V \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 142.4 \cdot 0.344\;(\sigma = 1.8) = 49\,\text{m}$
AP Pen Close761.8 mm
Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity: $P = 10^{-7}\cdot K \cdot m^{0.69} \cdot d^{-1.07} \cdot v_0^{1.38}$ $= 10^{-7}\cdot 2347 \cdot 885^{0.69} \cdot 0.38^{-1.07} \cdot 830^{1.38} = 761.8\,\text{mm}$. Matches the in-game spec card.
AP Pen Far424.3 mm
Same formula at the ship's max firing range (21.9 km), where the shell has slowed to 543.1 m/s: $P = 10^{-7}\cdot 2347 \cdot 885^{0.69} \cdot 0.38^{-1.07} \cdot 543.1^{1.38} = 424.3\,\text{mm}$.

AA defense

Close-range AA DPS591
Sum across every AA aura on this ship of (aura.continuous_damage x 3.5 x aura.hit_probability). Here: (161×3.5×0.75) + (64×3.5×0.75) = 591. 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.
Maximum AA range5 km
Longest-reaching aura across AA-only + dual-purpose auras.
AA threat index2742
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.

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 @ 4.5 km286.5 m
4.5 km × 57 + 30 = 286.5 m.

Secondary battery firepower

Secondary DPM (per side)385,500
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: 12×2 100 mm (12/side) × 60/3 × 1400 = 336,000 + 3×3 152 mm (4.5/side) × 60/12 × 2200 = 49,500. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).
Max HE alpha2200
Maximum HE damage per shell across secondary HE families. Best on this ship: 2200 from the 152 mm family.
Max HE fire chance12%
Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 12% from the 152 mm family.
Max HE pen25 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: 25 mm from the 152 mm family.

Armor Beta

Hull HP 69,000, 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 & stern32 mm

Overmatched by only MusashiARP Musashi. Angled, everything else bounces.

Belt / citadel330 mm

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

Farming19 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 37%, fires burn 60s. Range-by-range in the ballistics tool →

Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.

Mirror of bow. Same fast saturation.
Citadel330 mm primary (range 18–405 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.
Superstructure19 mm primary (range 19–405 mm)2,700 (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 HP34,500 magazine HPMagazine detonation1–30% chance · below ~75% HPPer-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 (152 mm mount)separate HP pool, does not drain ship HP800 per-mount HPDestroyed at 0 HPPer-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 (57 mm mount)separate HP pool, does not drain ship HP200 per-mount HPDestroyed at 0 HPPer-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 HP20,700 module HPIncapacitated at 0 HPWhen 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.
