Overview

Atlanta B is a Tier VI American light cruiser whose 127mm guns bring 302,400 HE DPM (1st of 37). Surveillance Radar (8.5 km) is the cap-control consumable on top, so she sets fights as well as winning them. She also puts out top-decile AP (352,800 AP DPM), making her a dual-threat gunship: keep AP up against broadsides and citadels, and switch to HE against bow-in ships, superstructures, and the thin or angled targets AP over-penetrates or bounces off. Standout traits: turret traverse rate in T6 CAs (25, 3rd of 44) and tight pattern at max range in T6 CAs (105.4 m, 2nd of 44). The trade is short gun range in T6 CAs (12.1 km, 44th of 44).

Positioning

Hold cover beside a contested cap, close enough that an island can break sightline when focus shifts. Radar reaches 8.5 km, so the drop only pays once you are near enough to use it: push it when the destroyer fight is yours, not to fish for a lone kill, or the next push has no answer to smoke or vision. Your guns lose penetration at range, so aim AP at broadsides you can still citadel and put HE into superstructures and upper-hull sections, rather than the bow-in or belt armor your shells bounce and shatter on. Her citadel sits high enough that even glancing broadside shots can land citadel pens; treat island cover as a hard requirement, not a preference. Trade only when the angle keeps the citadel sides hidden. Once the rudder is over she turns tightly for her cohort (610 m), so a committed turn costs less water than most of what she is fighting.

Potato Avoidance

Using radar like a destroyer hunter rather than a position tool

The consumable's value is locking down a cap your team can take, not stealing a single salvo on a lone DD. Burn it early to fish for a kill and the next push has no answer to smoke or vision. Yours reaches 8.5 km for 25 s, which is the whole window your team gets to act on what it shows.

Signature Traits

Paper-thin armor

Hull plating is thin enough that large-caliber AP shells overpenetrate clean when hitting broadside, dealing minimal damage. Angling or going bow-in adds effective thickness that can arm incoming shells, putting the exposed citadel at risk. Keep your broadside to large-caliber guns; only angle against mid-caliber AP.

Surveillance Radar

8.49 km range, 25 s duration. Detects all enemy ships within a fixed radius regardless of line-of-sight. Breaks smoke camps and wins the opening of a cap fight.

Fire resistance

top hull: 1 − 0.7003 fire coefficient = 30%. 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.

30%

Fire duration30 s

Fire damage

One unattended fire: 0.003 of max HP per second (0.3%) × 30 s = 0.09 of the pool; 0.09 × 27,500 HP = 2,475 HP on this ship. 4 fire points can burn at once.

Flood duration40 s

Flood damage

One unattended flood: 0.0025 of max HP per second (0.25%) × 40 s = 0.1 of the pool; 0.1 × 27,500 HP = 2,750 HP on this ship.

0.25% of HP per second

Torp Reduction

1 − 0.333 hull torpedo-damage coefficient / 0.333 unprotected baseline = 0%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.

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.

13,800

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.

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 × 1,300 = 2,600), 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.

1,300

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 × 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

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 × 20,600 = 41,200), 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.

20,600

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 × 1,900 = 3,800), 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 ×. 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.

1,900

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 × 1,600 = 3,200), 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.

1,600

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° − 148° (the most restricted aft-facing mount's arc) = 32° off bow; 180° − 146° (the most restricted forward-facing mount's arc) = 34° 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.

Reload time98 s

Projectile speed65.0 kt

Range4.5 km

Maximum simulated damage

Most targets only intersect one hull section, so a hit transfers about 1/3 of the warhead alpha (2/3 when the warhead blast >= 5000 and the burst reaches a second section). For this ship:

D_{sim} = α \cdot c = 46, 600 \cdot 0.333 = 15, 533

. In battle, a hit on the torpedo belt deals the per-hit figure × (1 − the target's torpedo protection %), a bow or stern hit deals it in full, and a torpedo never counts as a citadel hit.

≈ 15,533

Maximum damage (ammunition)

46,600 warhead alpha / 3 + 1,100 blast = 16,633. Warhead alpha / 3 plus the blast addend: the per-torpedo damage figure. The 'Maximum simulated damage' row above applies target geometry to the same warhead.

16,633

Torpedo module damage

Per-torpedo module/blast damage parameter. Most torpedoes carry 500 to 2,000; ships announced by WG as dealing increased module damage carry 9,000 to 12,000, so their hits knock out engines, rudders, and turrets far more often. Comparative figure.

1,100

Torpedo detectability1.3 km

Reaction time

How long a target has to dodge after your torpedo is spotted at its detectability range (lower means less warning):

t_{react} = \frac{1.3 km}{65 kt \times 2.6855} = 7.4 s

. 2.6855 converts knots to m/s on the game clock. Base value; commander torpedo-concealment skills lower it further.

7.4 s

Flooding chance

This torpedo carries a flooding-chance value of 2.79 per hit, shown as

2.79 \times 100 = 279 %

. Values above 100% are normal: in battle the base chance is scaled down by the target's torpedo protection (the Torp Reduction stat on its Survivability card) and any flood-resistance modifiers, so a value above 100% keeps flooding likely even through partial protection.

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 × 220 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.

220

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.

90%

Salvo interval

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

Fired by

Flak keeps firing while at least one main battery mount is operational - even losing every dedicated AA mount does not stop it.

Main 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.

Main battery formulas

vs standard cruiser9% tighter H · 9% shorter V

H = horizontal, V = vertical spread. This ship's curve against the standard cruiser curve, both evaluated at this ship's max range (12.1 km) with the same model as Max Horiz/Vert Disp: horizontal 105 / 116 m − 1 = -9%, vertical 63 / 70 m − 1 = -9%. Shell grouping (σ) is separate: it sets how shells bunch toward the centre of this ellipse.

Shell scatter width @ 5 km52.5 m

(166.7 × (8 − 0.5) / 1000 + 0.5) × 30 = 52.5 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 km90 m

(333.3 × (8 − 0.5) / 1000 + 0.5) × 30 = 90 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 height @ 5 km23.6 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  $delim \cdot R_{m a x} = 0.5 \cdot 12053 = 6026$  m, and  $radiusOnMax = 0.6$  at 12053 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{6026} = 0.4489$ , so  $σ_{V} = σ_{H} \cdot k = 52.5 \cdot 0.4489 = 23.6 m$ .

Shell scatter height @ 10 km50.9 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  $delim \cdot R_{m a x} = 0.5 \cdot 12053 = 6026$  m, and  $radiusOnMax = 0.6$  at 12053 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 6026}{12053 - 6026} = 0.5659$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5659 = 50.9 m$ .

AP pen 5 km104 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2598 \cdot 25^{0.69} \cdot {0.127}^{- 1.07} \cdot {463.7}^{1.38} = 104 mm$ , where 463.7 m/s is the shell's speed when it arrives at 5 km (from 792 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 km55 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2598 \cdot 25^{0.69} \cdot {0.127}^{- 1.07} \cdot {290.8}^{1.38} = 55 mm$ , where 290.8 m/s is the shell's speed when it arrives at 10 km (from 792 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 km8.17 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.347 \cdot {0.127}^{2}}{8 \cdot 25} = 8.79 \times 10^{- 5}$ . That runs from a 792 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 km8.28 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.347 \cdot {0.127}^{2}}{8 \cdot 24.5} = 8.97 \times 10^{- 5}$ . That runs from a 792 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)14

Counted from each mount's firing arc: most barrels that bear at once: 14 of 16, on the beam; casemate/wing mounts only fire one side.

Model inputs

Krupp (AP)2,598

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 mass25 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 coefficient0.347

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

AP muzzle velocity792 m/s

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

HE muzzle velocity792 m/s

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

idealRadius8

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

minRadius0.5

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.

Torpedoes

Estimated torpedo reaction time7.4 s

1300 m / (65.0 kt × 2.6855) = 7.4 s. detectability / (speed kt x 2.6855 m/s per knot on the game clock).

Torpedo speed65.0 kt

Travel time to max range25.8 s

4500 m / (65.0 kt × 2.6855) = 25.8 s. range / (speed kt x 2.6855 m/s per knot on the game clock).

Tube count8

2 launchers × 4 tubes.

Per-side salvo4 torpedoes

8 wing tubes / 2 = 4: the launchers sit one per beam, so only half of them reach any one side. Each launcher reloads on its own, so she can fire one beam, turn, and fire the other without waiting.

Full-salvo damage124,264

All tubes hitting one target: tubes x per-torpedo simulated damage = 8 x 15,533 = 124,264. Each hit on the target's torpedo belt is reduced by its torpedo protection %.

AA defense

AA DPS at max range148

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 1in Mk2 Mod2 4x4 -> 47 DPS @ 3.1 km; 20mm Oerlikon MK4 8x1 -> 57 DPS @ 2 km; Far AA (?) -> 148 DPS @ 5 km.

AA DPS layered by range148 DPS @ 5 km, 195 DPS @ 3.1 km, 252 DPS @ 2 km

@ 5 km: 148 from one family; @ 3.1 km: 47 + 148 = 195; @ 2 km: 47 + 57 + 148 = 252. 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-blank252

47 + 57 + 148 = 252 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index1000

47 × 3.1 + 57 × 2 + 148 × 5 = 1000. 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.

Background

A relatively small ship for her type featuring powerful AA armament and designed for use in joint operations with destroyers. The ship carried torpedo tubes and numerous dual-purpose rapid-fire artillery.

Armor Beta

Hull HP 27,500, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds.

Bow & stern13 mm

Overmatched by 181+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel89 mm

Thin belt: battleship AP citadels straight through it broadside. Rely on angle, speed and concealment, never sit flat.

Hull (midship)	25 mm	20,600 (75% of HP)	Overmatched by 380mm+ AP (Bayern, Richelieu)Angle bounces 356mm25 mm: HE pens from 150mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	13 mm primary (range 13–25 mm)	1,600 (6% of HP)	Overmatched by 203mm+ AP (Aoba, Baleares)Angle bounces 152mm13 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	89 mm primary (range 13–89 mm)	≈ 165,500 (effectively 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	6 mm primary (range 6–65 mm)	1,900 (7% of HP)	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).
Turret (module, per magazine)	separate HP pool, does not drain ship HP	13,800 magazine HP	Turret knocked out	Per-turret powder-magazine HP, a separate pool that does not drain ship HP. As it is worn down the turret is likelier to be knocked out, and a smaller pool gets there faster.
AA mount (28 mm mount)	separate HP pool, does not drain ship HP	200 per-mount HP	Destroyed at 0 HP	Per-mount HP for the heaviest AA on this ship. An AA mount destroyed at 0 HP stops shooting down planes for the rest of the battle; DCP does not repair destroyed mounts. HE shells specifically target AA mounts since the small-caliber HP pool falls fast.
Rudder (module)	separate HP pool, does not drain ship HP	8,300 module HP	Incapacitated at 0 HP	When module HP reaches 0 the rudder locks at its current angle until DCP repairs it. Repair via Damage Control Party.

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.
