Overview

BA Utnapishtim's Ship is a Tier VIII French super-cruiser: a battleship-sized hull with a 330mm main battery on a cruiser frame. She is built to overmatch broadside cruisers with AP, not to brawl with battleships. Sonar (4.4 km on ships and 3.1 km on torpedoes, 96 s active, 180 s reload, long uptime) lights up DDs and torpedoes inside its bubble, which lets her contest the cap edge without taking the spotting cycle. Standout traits: best AP overmatch threshold in T8 CAs (23 mm) and top-decile close-range AP pen in T8 CAs (675.7 mm).

Positioning

Hold 12-15 km from a contested cap with an island close enough to shadow back into, and bow toward the closest BB. The heavy bow plate lets you hold the angle against same-tier guns, which is the protection the citadel needs; the hull does not tank battleship volleys broadside even if it can absorb them bow-on. The big guns reach for full AP citadels at that distance. Her handling reads as a contradiction and is not one: 13.2 s on the rudder means she starts turning late, while a 720 m circle means she comes around inside most of her cohort once she does. Decide a beat early and the turn itself will not let you down.

Potato Avoidance

Sailing straight and flat

With 13.2-second rudder she answers the helm too late to dodge a salvo already in the air, so the angle has to be set before you are shot at, not after. Weave between salvos and keep the bow or stern toward whoever can citadel you. The compensation is the turn itself: 720 m is tight for her cohort, so once the rudder is over she comes around inside most of what she is fighting. Commit early and the turn pays; commit late and the rudder has already cost you the dodge.

Signature Traits

Engine Boost

+20% speed (about +6.3 kt), 180 s duration. Engine Boost consumable temporarily raises top speed. Mobility on demand to reposition, chase a kill, or break contact. Uncommon in T8 CAs.

ELITE MAIN BATTERY ↗

Big-caliber AP overmatch · 23 mm
Close-range AP brick · 675.7 mm
Long-range AP brick · 418.3 mm
Heavy HE shells · 4800 damage
High fire chance · 35%

Stiff AP fuse ↗

55 mm AP arming threshold, worst of T8 CAs. Over-pens thin plates; the trade-off pays off when most targets are battleship belt armor.

Slow acceleration ↗

~32.2 s to 90% of top speed, worst of T8 CAs. Sluggish rebuild after a turn or stop; the engine power-boost fades early, so the mid-range crawls.

Fire resistance

Does not reduce the damage a burning fire does per second: replay-measured burn ticks run at the full rate on every ship. By elimination it lowers how often hits set you on fire; ignition-rate replay data is consistent with that but too confounded by attacker mix to measure the reduction directly.

40%

Fire duration45 s

Fire damage

Each fire ticks 0.3% of max HP per second for the full 45 s, so one unattended fire burns 13.5% of the pool (8,100 HP on this ship). 4 fire points can burn at once. Verified against measured burn ticks in replay data.

0.3% of HP per second

Flood duration40 s

Flood damage

A flood ticks 0.25% of max HP per second for the 40 s duration, so one unattended flood costs 10% of the pool (6,000 HP on this ship). Verified against measured flood ticks in replay data.

0.25% of HP per second

Torp Reduction

Reduces torpedo hit damage. Replay data shows no effect on floods: flood ticks run at the full rate and flood frequency does not decline with protection.

19%

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.

27,700

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.

18,000

Effective HP

Base 60,000 HP plus everything Repair Party can restore: 0.6%/s x 28 s = 10,080 HP per charge, x2 charges = 20,160 HP. Ceiling, not a prediction: a charge only restores damage actually taken, and only the regeneratable share of it. Across 1,826 players in our replay corpus the median ship realized about half of this, mostly because half the charges go unspent — when Repair Party IS pressed it returns ~97% of the per-charge figure above. Repair Party is one choice in its slot on this ship, so this applies only if you take it.

How far each mount can train, in degrees to either side of the mount's own facing, read from in-game data. 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

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. Mount facing is inferred from turret stations and verified against known layouts, including Izumo's aft-facing forward turret.

Bursts

Each ~2 s wave fires 2 quick salvos of 4 clouds ahead of the attacking squadron, plus 2 stray clouds farther out that appear off-beat between waves - up to 10 clouds per wave × 250 damage each. Planes that fly into a cloud take its damage; clouds dissipate before the next wave lands. Defensive AA Fire, where fitted, multiplies the salvo repeats within each wave.

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 waves 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.

Wave rate

A flak wave spawns roughly every 2 s - timed frame-by-frame from gameplay footage and consistent across ships.

Fired by

Flak keeps firing while at least one secondary battery mount is operational - even losing every other 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 bursts can land short of 2.5 km or past 5.2 km - once planes get inside the band, new waves stop. AA range bonuses push the outer edge out; the 2.5 km inner edge does not move.

Traverse-to-turn ratio

How many degrees the turret can swing for each degree the hull turns. Turn rate

Shell Grouping (σ)1.7

Max Horiz Disp178.2 m at 15.5 km

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{15500}{30} \cdot \frac{10 - 1.6}{1000} + 1.6) \cdot 30 = 178.2 m$

Shell scatter width @ 5 km90 m

Horizontal scatter at a fixed 5 km, from the same verified dispersion model as the rows below - a knife-fight-range anchor comparable across ships.

Shell scatter width @ 10 km132 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 km174 m

Horizontal scatter at a fixed 15 km, from the same verified dispersion model - the long-range anchor. Only shown when the ship's guns reach 15 km.

Max Vert Disp106.9 m at 15.5 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 178.2 \cdot 0.6 = 106.9 m$

Shell scatter height @ 10 km69.8 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  $delim \cdot R_{m a x} = 0.5 \cdot 15500 = 7750$  m, and  $radiusOnMax = 0.6$  at 15500 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7750}{15500 - 7750} = 0.529$ , so  $σ_{V} = σ_{H} \cdot k = 132 \cdot 0.529 = 69.8 m$ .

Med Horiz Disp62.9 m at 15.5 km

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 178.2 \cdot \frac{0.6}{1.7} = 62.9 m$

Med Vert Disp37.7 m at 15.5 km

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 106.9 \cdot \frac{0.6}{1.7} = 37.7 m$

AP Pen Close713.2 mm point-blank

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2428 \cdot 560^{0.69} \cdot {0.33}^{- 1.07} \cdot 870^{1.38} = 713.2 mm$ . Matches the in-game spec card.

AP Pen Far418.3 mm at 15.5 km

Same formula at the ship's max firing range (15.5 km), where the shell has slowed to 591 m/s:  $P = 10^{- 7} \cdot 2428 \cdot 560^{0.69} \cdot {0.33}^{- 1.07} \cdot 591^{1.38} = 418.3 mm$ .

AP pen 5 km595 mm

AP penetration at a fixed 5 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 10 km500 mm

AP penetration at a fixed 10 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 15 km425 mm

AP penetration at a fixed 15 km, read off the same PC-validated ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the canonical community AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP flight time @ 10 km4.75 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2801 \cdot {0.33}^{2}}{8 \cdot 560} = 2.14 \times 10^{- 5}$ . That runs from a 870 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77: the game clock runs faster than real time, and that factor was measured against stopwatch runs in the Training Room. Lower is better, since a faster shell is harder to dodge and needs less lead.

HE flight time @ 10 km4.71 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2926 \cdot {0.33}^{2}}{8 \cdot 552} = 2.27 \times 10^{- 5}$ . That runs from a 885 m/s muzzle velocity in 0.02 s steps under gravity 9.8 m/s² until the shell lands, then divides by 2.77: the game clock runs faster than real time, and that factor was measured against stopwatch runs in the Training Room. Lower is better, since a faster shell is harder to dodge and needs less lead.

HE penetration55 mm

55 mm ≈ 330 mm caliber / 6 (standard HE penetration ratio).

AP overmatch23 mm

floor(330 mm caliber / 14.3) = 23 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius120

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.

Zero upgrades: 8 broadside guns x 60 / 23 s base reload = 20.9. All upgrades (Main Battery Mod. 3 = -10% reload): 8 broadside guns x 60 / 20.7 s all-upgrades reload = 23.2.

Fires/minInitial: 7.3 → 8.12

Zero upgrades: 20.9 shells/min x 35% fire chance = 7.3. All upgrades (Main Battery Mod. 3 = -10% reload): 23.2 shells/min x 35% fire chance = 8.12.

AA defense

AA DPS at max range132

Only families that reach 5.2 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors Mk1 4x2 -> 85 DPS @ 3.5 km; 40mm Bofors 4x4 -> 85 DPS @ 3.5 km; 20mm Oerlikon MK20 Twin 18x2 -> 196 DPS @ 2 km; 138mm 50 twin 8x2 -> 132 DPS @ 5.2 km.

Maximum AA range5.2 km

Longest-reaching family on the in-game AA card. Base AirDefense aura max range is 3.5 km; dual-purpose mount auras extend it.

AA DPS layered by range132 DPS @ 5.2 km, 302 DPS @ 3.5 km, 498 DPS @ 2 km

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-blank498

Sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index1673

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 dispersion

Secondary dispersion typeImproved (40%, German battlecruiser type)

Max dispersion = range (km) × 33 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.

Max secondary dispersion @ 5 km195 m

5 km × 33 + 30 = 195 m.

Secondary battery firepower

Secondary DPM (per side)137,143

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: 8×2 139 mm (8/side) × 60/7 × 2000 = 137,143. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Max HE alpha2000

Maximum HE damage per shell across secondary HE families. Best on this ship: 2000 from the 139 mm family.

Max HE fire chance10%

Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 10% from the 139 mm family.

Max HE pen23 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: 23 mm from the 139 mm family.

Armor Beta

Hull HP 60,000, 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.

Bow & stern25 mm

Overmatched by 100+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel190 mm

AP can citadel a flat broadside even at range. Stay angled and avoid showing the full side.

Farming16 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 40%, fires burn 45s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic

Citadel	190 mm primary (range 27–40 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	16 mm primary (range 16–120 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.
