Overview

BA Binah is a Tier VI Italian SAP battleship: her 381mm main battery fires semi-armor-piercing shells (96.7mm of fixed penetration) in place of AP. SAP lands a reliable guaranteed chunk on broadsides and superstructures instead of fishing for citadels, and pens without the angle checks AP lives or dies on. The catch is that SAP shatters on the heavy belt armor AP would punch through, so the kit rewards picking targets it bites over trading into an angled battleship. Standout traits: sigma in T6 BBs (2, 5th of 32) and main battery range in T6 BBs (16.6 km, 4th of 32). The trade is worst surface detection in T6 BBs (15 km, 32nd of 32).

Positioning

Sit 14-17 km from the brawl line and exploit the range advantage. You do not need to push into peer fire to land damage; rotate one or two map cells back if a flank starts to collapse. Once the rudder is over she turns tightly for her cohort (740 m), so a committed turn costs less water than most of what she is fighting.

Potato Avoidance

Burning Main Battery Reload Booster on a hopeful salvo

With only 2 charges it is a finisher rather than an opener: spend it on a target that cannot turn away, a broadside battleship or a cruiser already committed to its own attack, where the extra salvo lands as damage instead of splashes. A booster pressed on a maybe is one you will not have when the certainty shows up.

Fire damage

One unattended fire: 0.003 of max HP per second (0.3%) × 60 s = 0.18 of the pool; 0.18 × 50,500 HP = 9,090 HP on this ship. 4 fire points can burn at once.

Flood damage

One unattended flood: 0.005 of max HP per second (0.5%) × 40 s = 0.2 of the pool; 0.2 × 50,500 HP = 10,100 HP on this ship.

0.5% of HP per second

Torp Reduction

1 − 0.25 hull torpedo-damage coefficient / 0.333 unprotected baseline = 25%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.

25%

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.

25,300

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.

15,200

Effective HP

Base 50,500 HP plus everything Repair Party can restore: 0.005 of max HP per second (0.5%) × 28 s × 50,500 HP = 7,070 HP per charge, × 4 charges = 28,280 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.

Bow section HP

Damage saturation pool for the bow: 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 ×. 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

Casemate section HP

Damage saturation pool for the casemate: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 8,800 = 17,600), 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 ×. 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.

8,800

Hull section HP

Damage saturation pool for the hull: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 37,900 = 75,800), 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.

37,900

Superstructure section HP

Damage saturation pool for the superstructure: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 2,300 = 4,600), 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 ×. 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.

2,300

Stern section HP

Damage saturation pool for the stern: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 1,400 = 2,800), 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.

Citadel section HP

This section has no practical saturation cap: every hit here keeps dealing its normal share of damage (on most ships the citadel; on many destroyers the casemate).

Turret traverse arcs

How far each mount can train, in degrees to either side of the mount's own facing. 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

180° − 150° (the most restricted aft-facing mount's arc) = 30° off bow; 180° − 150° (the most restricted forward-facing mount's arc) = 30° off stern. 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.

AA explosions

Each ~2 s salvo fires 2 AA explosions in quick succession, each leaving 4 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between salvos - up to 9 clouds per salvo × 170 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.

2 per salvo, 4 clouds each + 1 outer cloud

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 salvos 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.

Salvo interval

A new flak salvo (the AA explosions above) fires roughly every 2 s.

Flak keeps firing while at least one secondary battery mount is operational - even losing every dedicated 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 clouds can land short of 2.5 km or past 4 km - once planes get inside the band, new salvos stop. AA range bonuses push the outer edge out; the 2.5 km inner edge does not move.

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 (16.6 km) with the same model as Max Horiz/Vert Disp: horizontal 229 / 226 m − 1 = +1%, vertical 137 / 136 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 km43.8 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  $delim \cdot R_{m a x} = 0.5 \cdot 16600 = 8300$  m, and  $radiusOnMax = 0.6$  at 16600 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{8300} = 0.3807$ , so  $σ_{V} = σ_{H} \cdot k = 115 \cdot 0.3807 = 43.8 m$ .

Shell scatter height @ 10 km85.4 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. 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  $delim \cdot R_{m a x} = 0.5 \cdot 16600 = 8300$  m, and  $radiusOnMax = 0.6$  at 16600 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 8300}{16600 - 8300} = 0.5205$ , so  $σ_{V} = σ_{H} \cdot k = 164 \cdot 0.5205 = 85.4 m$ .

Shell scatter height @ 15 km123.7 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  $delim \cdot R_{m a x} = 0.5 \cdot 16600 = 8300$  m, and  $radiusOnMax = 0.6$  at 16600 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{15000 - 8300}{16600 - 8300} = 0.5807$ , so  $σ_{V} = σ_{H} \cdot k = 213 \cdot 0.5807 = 123.7 m$ .

AP pen 5 km693 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2434 \cdot {884.8}^{0.69} \cdot {0.381}^{- 1.07} \cdot {756.7}^{1.38} = 693 mm$ , where 756.7 m/s is the shell's speed when it arrives at 5 km (from 850 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 km593 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2434 \cdot {884.8}^{0.69} \cdot {0.381}^{- 1.07} \cdot 676^{1.38} = 593 mm$ , where 676 m/s is the shell's speed when it arrives at 10 km (from 850 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 km514 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2434 \cdot {884.8}^{0.69} \cdot {0.381}^{- 1.07} \cdot {608.7}^{1.38} = 514 mm$ , where 608.7 m/s is the shell's speed when it arrives at 15 km (from 850 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP flight time @ 10 km4.79 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2954 \cdot {0.381}^{2}}{8 \cdot 884.8} = 1.9 \times 10^{- 5}$ . That runs from a 850 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.

Guns per full salvo (alpha, DPM)8

4 mounts × 2 barrels = 8; all 8 bear on the broadside.

Model inputs

Krupp (AP)2,434

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 mass884.8 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 coefficient0.2954

Air drag on the AP shell in flight; lower keeps velocity, and with it penetration, at long range.

AP muzzle velocity850 m/s

Starting speed of the AP shell; penetration scales with velocity^1.38.

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 range110

Only families that reach 4 km contribute at the outer edge of the AA bubble. In-game families: Breda 37mm double 8x2 -> 129 DPS @ 3.5 km; 20mm65 Breda M1935 double 2x2 -> 18 DPS @ 2 km; 20mm70 Breda barrels 6 8x6 -> 71 DPS @ 2 km; 90mm50 barrels 1 M1939 12x1 -> 110 DPS @ 4 km.

AA DPS layered by range110 DPS @ 4 km, 239 DPS @ 3.5 km, 328 DPS @ 2 km

@ 4 km: 110 from one family; @ 3.5 km: 129 + 110 = 239; @ 2 km: 129 + 18 + 71 + 110 = 328. 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-blank328

129 + 18 + 71 + 110 = 328 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index1070

129 × 3.5 + 18 × 2 + 71 × 2 + 110 × 4 = 1070. 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 firepower

Max HE alpha2100

max(2100 (152 mm), 2100 (152 mm), 1300 (90 mm)) = 2100. Maximum HE damage per shell across secondary HE families. Best on this ship: 2100 from the 152 mm family.

Max HE fire chance7%

max(7% (152 mm), 7% (152 mm), 5% (90 mm)) = 7%. Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 7% from the 152 mm family.

Max HE pen25 mm

max(25 mm (152 mm), 25 mm (152 mm), 15 mm (90 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 first super dreadnoughts of the Regia Marina designed to carry 381 mm guns. Construction of the ships commenced during World War I and were designed to match the new fast battleships being built for foreign navies.

Armor Beta

Hull HP 50,500, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are estimates.

Bow & stern26 mm

Overmatched by 81+ 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.

Farming16 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 40–150 mm)	≈ 2,525 (~5% 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.
Hull (midship)	16 mm primary (range 16–300 mm)	≈ 37,875 (~75% of HP)	Overmatched by 283mm+ AP (Graf Spee, Scharnhorst)Angle bounces 203mm16 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	26 mm primary (range 26–300 mm)	≈ 2,525 (~5% of HP)	Overmatched by 380mm+ AP (Bayern, Richelieu)Angle bounces 356mm26 mm: HE pens from 203mm+	Mirror of bow. Same fast saturation.
Citadel	300 mm primary (range 16–300 mm)	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	26 mm primary (range 26–340 mm)	no cap	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).

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.
