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: top-decile sharp rudder in T7 BBs (12.3 s) and top-decile fast AP shells in T7 BBs (11.3 s).
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.
The main battery cycle is long enough that a punished broadside loses more HP than the next salvo gains; commit angles and finish reloads behind cover when the line allows.
12.3 s rudder shift, top decile of T7 BBs. Snappy weave.
15.0% best HE fire chance per secondary shell (before target resistance), top decile of T7 BBs. Stacks fires faster than peers in a brawl.
40.0 s Damage Control reload, top quartile of T7 BBs. Fire / flood stacks come off cooldown sooner.
Bow plate thicker than the cohort overmatch threshold. Angle straight on and shrug off same-tier guns.

Where BA Hovercraft sits among Tier VII BBs (48 ships). Notable standouts are shown first; the rest of the cohort-ranked stats are in the expand below. Acquisition variants (Black Friday, Founders Edition) are counted once with their base ship, not as separate peers.
Not standouts for BA Hovercraft -- here's where she sits on every other ranked stat in the cohort. Stats tagged NORM are tied across more than half the cohort, so the value is the cohort default rather than a standout.

Numbers the spec table cannot show directly: alpha-strike math, DPM, dispersion, AP penetration. Click the formula chip on any row to reveal how it is calculated.
Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model: $\sigma_H = \left(\dfrac{R}{30}\cdot\dfrac{\text{idealRadius}-\text{minRadius}}{\text{idealDistance}} + \text{minRadius}\right)\cdot 30$ $= \left(\dfrac{16000}{30}\cdot\dfrac{13-1.1}{1000} + 1.1\right)\cdot 30 = 223.4\,\text{m}$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: $\sigma_V = \sigma_H \cdot \text{radiusOnMax}$ $= 223.4 \cdot 0.75 = 167.6\,\text{m}$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: $\sigma_{H,50} = \sigma_H \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 223.4 \cdot 0.369\;(\sigma = 1.6) = 82.5\,\text{m}$50%-hit vertical radius: $\sigma_{V,50} = \sigma_V \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 167.6 \cdot 0.369\;(\sigma = 1.6) = 61.8\,\text{m}$Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity: $P = 10^{-7}\cdot K \cdot m^{0.69} \cdot d^{-1.07} \cdot v_0^{1.38}$ $= 10^{-7}\cdot 2300 \cdot 1116^{0.69} \cdot 0.406^{-1.07} \cdot 793^{1.38} = 766.5\,\text{mm}$. Matches the in-game spec card.Same formula at the ship's max firing range (20 km), where the shell has slowed to 547.9 m/s: $P = 10^{-7}\cdot 2300 \cdot 1116^{0.69} \cdot 0.406^{-1.07} \cdot 547.9^{1.38} = 460.2\,\text{mm}$.68 mm ≈ 406 mm caliber / 6 (standard HE penetration ratio).floor(406 mm caliber / 14.3) = 28 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 9 barrels bear on the broadside.180 degrees / 5 deg/s traverse speed = 36 s.5,850 HE damage x 9 broadside guns = 52,650.13,100 AP damage x 9 broadside guns = 117,900.52,650 HE full-salvo alpha x 60 / 31 s base reload = 101,903.117,900 AP full-salvo alpha x 60 / 31 s base reload = 228,194.52,650 HE full-salvo alpha x 60 / 27.9 s installed reload (Main Battery Mod. 3 = -10%) = 113,226.117,900 AP full-salvo alpha x 60 / 27.9 s installed reload (Main Battery Mod. 3 = -10%) = 253,548.9 broadside guns x 60 / 31 s base reload = 17.4.9 broadside guns x 60 / 27.9 s installed Artillery reload = 19.4.17.4 shells/min x 41% fire chance = 7.14.19.4 shells/min x 41% fire chance = 7.94.Sum across every AA aura on this ship of (aura.continuous_damage x 3.5 x aura.hit_probability). Here: (90×3.5×0.75) + (32×3.5×0.75) = 320. 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) × 57 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.6.5 km × 57 + 30 = 400.5 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: 3×2 100 mm (3/side) × 60/3.75 × 1330 = 63,840 + 3×2 100 mm (3/side) × 60/3.75 × 1330 = 63,840 + 6×2 152 mm (6/side) × 60/8 × 2100 = 94,500. 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: 2100 from the 152 mm family.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.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.Hull HP 67,500, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are estimated from the standard WoWs damage-allocation model.
Overmatched by only MusashiARP Musashi. Angled, everything else bounces.
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 37%, fires burn 60s. Range-by-range in the ballistics tool →
| Section | Plates | HP cap | Threats | Tactic |

| Bow | 32 mm primary (range 32–200 mm) | ≈ 3,375 (~5% of HP) | Overmatched by 460mm+ (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 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+ (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.
