Overview

BA Hovercraft is a Tier VII Soviet all-rounder battleship with 406mm guns at 16 km: she has no single dominant kit trait but is competent across the board. The role flexes by team comp - mid-range AP anchor by default, brawl support when the team commits, sniper when the line sits back. Versatility is the value, not specialization. Standout traits: heavy AP shells in T7 BBs (13,100, 11th of 49) and burny secondaries in T7 BBs (15, 2nd of 46). The trade is short gun range in T7 BBs (16 km, 49th of 49).

Positioning

Anchor a flank at 14-17 km with bow toward the closest threat. Rotate one or two map cells with the team rather than holding solo; a battleship alone on a flank is a free focus target for the enemy. 67,500 HP is what a rotation started too late costs, and it is spent before the guns that punished it come off cooldown. The helm answers fast (12.3 s) but the circle is wide (950 m): weave to spoil aim rather than committing to turns, because a committed turn gives up more water than the quick rudder saves you.

Potato Avoidance

Spending damage control on the first fire

Almost every ship in the game repairs indefinitely, so the habit is to press it the moment anything catches; she carries 3 charges and no more. Ride a single fire when your health allows and save the charge for a flood or a multi-fire stack, because the salvo after the one you repaired is the one that sinks you.

Fire resistance

top hull: 1 − 0.6337 fire coefficient = 36.6%. Lowers how often hits set you on fire. It does not reduce the damage a burning fire does per second; fires burn at the full rate on every ship.

36.6%

Fire duration60 s

Fire damage

One unattended fire: 0.003 of max HP per second (0.3%) × 60 s = 0.18 of the pool; 0.18 × 67,500 HP = 12,150 HP on this ship. 4 fire points can burn at once.

0.3% of HP per second

Flood duration40 s

Flood damage

One unattended flood: 0.005 of max HP per second (0.5%) × 40 s = 0.2 of the pool; 0.2 × 67,500 HP = 13,500 HP on this ship.

0.5% of HP per second

Torp Reduction

1 − 0.262 hull torpedo-damage coefficient / 0.333 unprotected baseline = 21%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.

21%

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.

36,800

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.

20,300

Effective HP

Base 67,500 HP plus everything Repair Party can restore: 0.005 of max HP per second (0.5%) × 28 s × 67,500 HP = 9,450 HP per charge, × 2 charges = 18,900 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 × 8,200 = 16,400), 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.

8,200

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 × 3,100 = 6,200), 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.

Auxiliary section HP

Damage saturation pool for the auxiliary room: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 2,800 = 5,600), 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.

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 × 50,600 = 101,200), 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.

50,600

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 × 1,800 = 3,600), 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.

1,800

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 × 4,300 = 8,600), 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.

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.

2x ±150°, ±145°

Guns to bear

180° − 145° (the most restricted aft-facing mount's arc) = 35° 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 × 200 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.

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 5 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.

12.7 kt

Crash stop

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, using the ship's own reverse-power ratio. The full curve is on the acceleration chart. Full reverse stops about a quarter faster than a plain Stop order from top speed.

Speed below which the engine's built-in power boost applies in reverse.

8.7 kt

Acceleration 0-90%

Time to reach 90% of top speed (27.9 kt of 31.0 kt).

33.1 s

Acceleration 0-99%

Time to reach 99% of top speed (30.7 kt of 31.0 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.

Guns in a full turn

With the rudder hard over the hull turns 3.6°/s, so a target drifts across the bow at that rate. Turret traverse minus hull turn: 5 − 3.6 = +1.4°/s, so the guns hold the target through the turn. Main Battery Mod. 2 (+20% traverse) and Mod. 3 (−15%) move this line.

Main battery formulas

vs standard BB2% wider H · 27% taller V

H = horizontal, V = vertical spread. This ship's curve against the standard battleship curve, both evaluated at this ship's max range (16.0 km) with the same model as Max Horiz/Vert Disp: horizontal 223 / 220 m − 1 = +2%, vertical 168 / 132 m − 1 = +27%. Shell grouping (σ) is separate: it sets how shells bunch toward the centre of this ellipse.

Shell scatter width @ 5 km92.5 m

(166.7 × (13 − 1.1) / 1000 + 1.1) × 30 = 92.5 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 km152 m

(333.3 × (13 − 1.1) / 1000 + 1.1) × 30 = 152 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 km211.5 m

(500 × (13 − 1.1) / 1000 + 1.1) × 30 = 211.5 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 km30.4 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:  $radiusOnZero = 0.25$  at 0 m,  $radiusOnDelim = 0.4$  at  $delim \cdot R_{m a x} = 0.6 \cdot 16000 = 9600$  m, and  $radiusOnMax = 0.75$  at 16000 m. Below the kink:  $k = 0.25 + (0.4 - 0.25) \cdot \frac{5000}{9600} = 0.3281$ , so  $σ_{V} = σ_{H} \cdot k = 92.5 \cdot 0.3281 = 30.4 m$ .

Shell scatter height @ 10 km64.1 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:  $radiusOnZero = 0.25$  at 0 m,  $radiusOnDelim = 0.4$  at  $delim \cdot R_{m a x} = 0.6 \cdot 16000 = 9600$  m, and  $radiusOnMax = 0.75$  at 16000 m. Above the kink:  $k = 0.4 + (0.75 - 0.4) \cdot \frac{10000 - 9600}{16000 - 9600} = 0.4219$ , so  $σ_{V} = σ_{H} \cdot k = 152 \cdot 0.4219 = 64.1 m$ .

Shell scatter height @ 15 km147.1 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:  $radiusOnZero = 0.25$  at 0 m,  $radiusOnDelim = 0.4$  at  $delim \cdot R_{m a x} = 0.6 \cdot 16000 = 9600$  m, and  $radiusOnMax = 0.75$  at 16000 m. Above the kink:  $k = 0.4 + (0.75 - 0.4) \cdot \frac{15000 - 9600}{16000 - 9600} = 0.6953$ , so  $σ_{V} = σ_{H} \cdot k = 211.5 \cdot 0.6953 = 147.1 m$ .

AP pen 5 km666 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2300 \cdot 1116^{0.69} \cdot {0.406}^{- 1.07} \cdot {715.9}^{1.38} = 666 mm$ , where 715.9 m/s is the shell's speed when it arrives at 5 km (from 793 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 km581 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2300 \cdot 1116^{0.69} \cdot {0.406}^{- 1.07} \cdot {648.4}^{1.38} = 581 mm$ , where 648.4 m/s is the shell's speed when it arrives at 10 km (from 793 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 km512 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2300 \cdot 1116^{0.69} \cdot {0.406}^{- 1.07} \cdot 592^{1.38} = 512 mm$ , where 592 m/s is the shell's speed when it arrives at 15 km (from 793 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 km5.07 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.289 \cdot {0.406}^{2}}{8 \cdot 1116} = 1.68 \times 10^{- 5}$ . That runs from a 793 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.

HE flight time @ 10 km5.07 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.289 \cdot {0.406}^{2}}{8 \cdot 1116} = 1.68 \times 10^{- 5}$ . That runs from a 793 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)9

3 mounts × 3 barrels = 9; all 9 bear on the broadside.

Model inputs

Krupp (AP)2,300

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 mass1,116 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 coefficient0.289

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

AP muzzle velocity793 m/s

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

HE muzzle velocity793 m/s

Starting speed of the HE shell; sets its flight time and lead.

idealRadius13

Horizontal dispersion growth per idealDistance of range, in 30 m units; the slope of the scatter-width line.

minRadius1.1

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.

radiusOnZero0.25

Vertical scatter as a share of horizontal at zero range.

radiusOnDelim0.4

Vertical scatter as a share of horizontal at the delim point.

radiusOnMax0.75

Vertical scatter as a share of horizontal at maximum range.

delim0.6

Where the vertical-scatter curve bends, as a share of maximum range.

AA defense

AA DPS at max range84

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 37mm 67 V21 6x2 -> 89 DPS @ 3.5 km; 37mm 46k 10x4 -> 148 DPS @ 3.5 km; 100mm 56 MZ 14 Left 3x2 -> 42 DPS @ 5 km; 100mm 56 MZ 14 Right 3x2 -> 42 DPS @ 5 km.

AA DPS layered by range84 DPS @ 5 km, 321 DPS @ 3.5 km

@ 5 km: 42 + 42 = 84; @ 3.5 km: 89 + 148 + 42 + 42 = 321. 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-blank321

89 + 148 + 42 + 42 = 321 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (3.5 km).

AA threat index1250

89 × 3.5 + 148 × 3.5 + 42 × 5 + 42 × 5 = 1250. 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 km217.5 m

Same per-type line evaluated at a fixed 5 km: 5 km × 37.5 + 30 = 217.5 m.

Secondary battery firepower

Max HE alpha2100

max(1330 (100 mm), 1330 (100 mm), 2100 (152 mm)) = 2100. Maximum HE damage per shell across secondary HE families. Best on this ship: 2100 from the 152 mm family.

Max HE fire chance15%

max(8% (100 mm), 8% (100 mm), 15% (152 mm)) = 15%. Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 15% from the 152 mm family.

Max HE pen25 mm

max(17 mm (100 mm), 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

One of the variants of the "battleship A" project intended for construction in accordance with the Great Ocean Fleet concept creation. She had heavy armor, high speed, and aviation equipment.

Armor Beta

Hull HP 67,500, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are estimates.

Bow & stern32 mm

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

Belt / citadel370 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 Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	32 mm primary (range 32–200 mm)	≈ 3,375 (~5% of HP)	Overmatched by 460mm+ AP (Aki, Musashi)Angle bounces 410mm32 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)	50 mm primary (range 25–425 mm)	≈ 50,625 (~75% of HP)	No common AP caliber overmatches50 mm: most HE shatters, standard pen from 305mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	32 mm primary (range 32–200 mm)	≈ 3,375 (~5% of HP)	Overmatched by 460mm+ AP (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+	Mirror of bow. Same fast saturation.
Citadel	370 mm primary (range 30–370 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	19 mm primary (range 19–40 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.
