Overview

La Foudre 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: sharp rudder in T7 BBs (12.7 s, 3rd of 49) and burny secondaries in T7 BBs (12, 9th of 46). The trade is short gun range in T7 BBs (16.5 km, 47th of 49).

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. The helm answers quickly (12.7 s), so she can break an incoming salvo that slower hulls have to eat.

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 (about +2.4 kt), 180 s duration. Engine Boost consumable gives a small speed nudge - useful for closing a gap or easing out of a bad angle, not for running anything down. Uncommon in T7 BBs.

Sharp rudder ↗

12.7 s rudder shift, top decile of T7 BBs. Snappy weave.

ELITE SECONDARIES ↗
  • Burny secondaries · 12%
  • Sharp secondaries
  • Secondary fire pressure · 14.7 secondary
Flat-trajectory sniper

Flat trajectory and high velocity retention. Easy aim at range, hard for targets to dodge.

WEAK MAIN BATTERY ↗
  • Short gun range · 16.5 km
  • Pattern widens fast with range

Torp Reduction
ƒ1 − 0.225 hull torpedo-damage coefficient / 0.333 unprotected baseline = 32%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.

Magazine HP
ƒPer-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.
34,500
Steering gear HP
ƒDurability 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.

Effective HP
ƒBase 69,000 HP plus everything Repair Party can restore: 0.005 of max HP per second (0.5%) × 28 s × 69,000 HP = 9,660 HP per charge, × 3 charges = 28,980 HP. Ceiling, not a prediction: a charge only restores damage actually taken, and only the regeneratable share of it. In practice ships realize about half of this, mostly because half the charges go unspent; a charge that is used returns about 97% of the per-charge figure above.

Section HP
Bow section HP
ƒDamage saturation pool for the bow: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 3,500 = 7,000), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.
3,500
Casemate section HP
ƒDamage saturation pool for the casemate: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 6,000 = 12,000), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495.

ƒDamage saturation pool for the auxiliary room: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 5,200 = 10,400), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495.

ƒDamage saturation pool for the hull: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 51,800 = 103,600), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495.

Superstructure section HP
ƒDamage saturation pool for the superstructure: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 2,700 = 5,400), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×. The superstructure is not exempt: it saturates exactly like the bow and stern, so shells aimed at it stop dealing full damage once this pool is used up. A larger pool keeps that part of the ship taking full damage for longer; a small one saturates fast and protects the ship's HP.
2,700
Stern section HP
ƒDamage saturation pool for the stern: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 3,300 = 6,600), then further hits on it deal half damage. A penetration deals 0.33 × the shell's max damage; once the section is saturated it deals exactly half of that (0.5 × 0.33 = 0.165 × max damage), so a 3,000-damage shell's pen goes from 990 to 495. Overpens (0.1 × max damage) and citadels (1.0 ×) ignore saturation. Pens on the ship's other, unsaturated sections still deal the normal 0.33 ×.

Guns to bear
ƒCounted from each mount's firing arc: no mount leaves a blind wedge, so every gun bears straight ahead. 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.

Flak
AA explosions
ƒEach ~2 s salvo fires 2 AA explosions in quick succession, each leaving 4 clouds ahead of the attacking squadron, plus 2 stray clouds farther out that appear off-beat between salvos - up to 10 clouds per salvo × 210 damage each. Planes that fly into a cloud take its damage; clouds dissipate before the next salvo lands. Defensive AA Fire, where fitted, multiplies the AA explosions within each salvo, and commander skills that raise the Number of AA explosions add to it.

Main battery formulas

vs standard BB1% wider H · 1% taller V
H = horizontal, V = vertical spread. This ship's curve against the standard battleship curve, both evaluated at this ship's max range (16.5 km) with the same model as Max Horiz/Vert Disp: horizontal 228 / 225 m − 1 = +1%, vertical 137 / 135 m − 1 = +1%. Shell grouping (σ) is separate: it sets how shells bunch toward the centre of this ellipse.
Shell scatter width @ 5 km115 m
(166.7 × (12 − 2.2) / 1000 + 2.2) × 30 = 115 m. Horizontal scatter at a fixed 5 km, from the same dispersion model as the rows below - a knife-fight-range anchor comparable across ships.
Shell scatter width @ 10 km164 m
(333.3 × (12 − 2.2) / 1000 + 2.2) × 30 = 164 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
(500 × (12 − 2.2) / 1000 + 2.2) × 30 = 213 m. Horizontal scatter at a fixed 15 km, from the same dispersion model - the long-range anchor. Only shown when the ship's guns reach 15 km.
Shell scatter height @ 5 km43.9 m
How tall the scatter ellipse is at a fixed 5 km, from the same model, comparable from ship to ship. 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·Rmax=0.5·16482=8241 m, and radiusOnMax=0.6 at 16482 m. Below the kink: k=0.2+(0.5−0.2)·50008241=0.382, so σV=σH·k=115·0.382=43.9m.
Shell scatter height @ 10 km85.5 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·Rmax=0.5·16482=8241 m, and radiusOnMax=0.6 at 16482 m. Above the kink: k=0.5+(0.6−0.5)·10000−824116482−8241=0.5213, so σV=σH·k=164·0.5213=85.5m.
Shell scatter height @ 15 km124 m
How tall the scatter ellipse is at a fixed 15 km, from the same model. Only shown when the ship's guns reach 15 km. 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·Rmax=0.5·16482=8241 m, and radiusOnMax=0.6 at 16482 m. Above the kink: k=0.5+(0.6−0.5)·15000−824116482−8241=0.582, so σV=σH·k=213·0.582=124m.
AP pen 5 km655 mm
AP penetration at a fixed 5 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula P=10−7·K·m0.69·d−1.07·v1.38 =10−7·2347·8850.69·0.38−1.07·744.11.38=655mm, where 744.1 m/s is the shell's speed when it arrives at 5 km (from 830 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.
AP pen 10 km566 mm
AP penetration at a fixed 10 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula P=10−7·K·m0.69·d−1.07·v1.38 =10−7·2347·8850.69·0.38−1.07·669.21.38=566mm, where 669.2 m/s is the shell's speed when it arrives at 10 km (from 830 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.
AP pen 15 km495 mm
AP penetration at a fixed 15 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula P=10−7·K·m0.69·d−1.07·v1.38 =10−7·2347·8850.69·0.38−1.07·606.91.38=495mm, where 606.9 m/s is the shell's speed when it arrives at 15 km (from 830 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.
HE flight time @ 10 km4.87 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, adrag=kρv2, where ρ is air density from a standard-atmosphere profile and k bundles the shell's drag coefficient, caliber and mass: k=πCdd28m=π·0.2791·0.3828·884=1.79×10−5. That runs from a 830 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77 because the game clock runs faster than real time. Lower is better, since a faster shell is harder to dodge and needs less lead.

Model inputs

Krupp (AP)2,347
Armor-penetration constant of the AP shell; penetration scales straight with it, so a 10% higher Krupp is 10% more penetration at every range.
AP shell mass885 kg
Enters penetration as mass^0.69 and slows the shell's drag deceleration, so a heavier shell keeps more velocity at range.
AP drag coefficient0.2791
Air drag on the AP shell in flight; lower keeps velocity, and with it penetration, at long range.
AP muzzle velocity830 m/s
Starting speed of the AP shell; penetration scales with velocity^1.38.
HE muzzle velocity830 m/s
Starting speed of the HE shell; sets its flight time and lead.
idealRadius12
Horizontal dispersion growth per idealDistance of range, in 30 m units; the slope of the scatter-width line.
minRadius2.2
Horizontal dispersion at zero range, in 30 m units; the intercept of the scatter-width line.
idealDistance1,000 m
Range step over which horizontal dispersion grows by idealRadius.
taperDist4,000 m
Inside this range the scatter width tapers toward minRadius instead of following the line.
radiusOnZero0.2
Vertical scatter as a share of horizontal at zero range.
radiusOnDelim0.5
Vertical scatter as a share of horizontal at the delim point.
radiusOnMax0.6
Vertical scatter as a share of horizontal at maximum range.
delim0.5
Where the vertical-scatter curve bends, as a share of maximum range.

AA defense

AA DPS at max range168
Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 57mm 60 2 25 1951 14x2 -> 423 DPS @ 4.5 km; 2 100 55 Mle 1945 12x2 -> 134 DPS @ 5 km; 152 55 Mle 1936 3x3 -> 34 DPS @ 5 km.
AA DPS layered by range168 DPS @ 5 km, 591 DPS @ 4.5 km
@ 5 km: 134 + 34 = 168; @ 4.5 km: 423 + 134 + 34 = 591. 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-blank591
423 + 134 + 34 = 591 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (4.5 km).
AA threat index2744
423 × 4.5 + 134 × 5 + 34 × 5 = 2744. 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 @ 5 km315 m
Same per-type line evaluated at a fixed 5 km: 5 km × 57 + 30 = 315 m.

Secondary battery firepower

Max HE alpha2350
max(1550 (100 mm), 2350 (152 mm)) = 2350. Maximum HE damage per shell across secondary HE families. Best on this ship: 2350 from the 152 mm family.
Max HE fire chance12%
max(5% (100 mm), 12% (152 mm)) = 12%. 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
max(17 mm (100 mm), 25 mm (152 mm)) = 25 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.

Background

The favorite vessel of pirate legend Michel Le Tir packs quite a punch! La Foudre is the flagship of the French pirate fleet, and for good reasons: She's speedy, agile, and dangerous with her enhanced secondaries, just like any pirate wants their ship to be. If you think she resembles battleship Jean Bart, you're onto something - Le Tir spent years recreating the ship that bore his idol's name.
