Overview

Worcester is a Legendary American light cruiser whose 152mm guns bring 18.3 fires a minute (1st of 19). Surveillance Radar (9 km) is the cap-control consumable on top, so she sets fights as well as winning them. Both shells run cohort-strong (cohort-strong AP at 488,727 AP DPM and cohort-strong HE at 336,000 HE 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. AA (689 AA DPS at 6 km, +100% Defensive AA flak burst) ranks 2 of 21 in Legendary CAs: heavy enough to make a careless strike expensive, though not the umbrella that shuts a carrier out of her grid. Standout traits: end-plate armor in Legendary CAs (32 mm, 3rd of 21) and best bow armor in Legendary CAs (32 mm, 3rd of 21). The trade is short gun range in Legendary CAs (15.3 km, 19th of 21).

Positioning

Hold cover beside a contested cap, close enough that an island can break sightline when focus shifts. Radar reaches 9 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. She is genuinely evasive in both phases of a turn, answering the helm in 8.2 s and carving a 740 m circle, so you can break a salvo and still be where you meant to go.

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 9 km for 30 s, which is the whole window your team gets to act on what it shows.

Signature Traits

Surveillance Radar

9 km range, 30 s duration. Detects all enemy ships within a fixed radius regardless of line-of-sight. Controls caps and punishes smoke-firing DDs.

Fire resistance

top hull: 1 − 0.6004 fire coefficient = 40%. 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.

40%

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 × 45,400 HP = 4,086 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 × 45,400 HP = 4,540 HP on this ship.

0.25% of HP per second

Torp Reduction

1 − 0.27 hull torpedo-damage coefficient / 0.333 unprotected baseline = 19%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.

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.

22,700

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.

13,600

Effective HP

Base 45,400 HP plus everything Repair Party can restore: 0.005 of max HP per second (0.5%) × 28 s × 45,400 HP = 6,356 HP per charge, × 2 charges = 12,712 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 × 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.

1,400

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 × 6,400 = 12,800), 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.

6,400

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 × 34,100 = 68,200), 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.

34,100

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 × 2,200 = 4,400), 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 ×. 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.

2,200

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 × 3,600 = 7,200), 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.

3,600

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.

6x ±146°

Guns to bear

180° − 146° (the most restricted aft-facing mount's arc) = 34° 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.

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 × 240 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.

240

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.

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 6 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 cruiserStandard

The standard cruiser dispersion curve.

Shell scatter width @ 5 km67.5 m

(166.7 × (8 − 1.1) / 1000 + 1.1) × 30 = 67.5 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 km102 m

(333.3 × (8 − 1.1) / 1000 + 1.1) × 30 = 102 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 km136.5 m

(500 × (8 − 1.1) / 1000 + 1.1) × 30 = 136.5 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 km26.7 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  $delim \cdot R_{m a x} = 0.5 \cdot 15339 = 7670$  m, and  $radiusOnMax = 0.6$  at 15339 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{7670} = 0.3956$ , so  $σ_{V} = σ_{H} \cdot k = 67.5 \cdot 0.3956 = 26.7 m$ .

Shell scatter height @ 10 km54.1 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:  $radiusOnZero = 0.2$  at 0 m,  $radiusOnDelim = 0.5$  at  $delim \cdot R_{m a x} = 0.5 \cdot 15339 = 7670$  m, and  $radiusOnMax = 0.6$  at 15339 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7670}{15339 - 7670} = 0.5304$ , so  $σ_{V} = σ_{H} \cdot k = 102 \cdot 0.5304 = 54.1 m$ .

Shell scatter height @ 15 km81.3 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  $delim \cdot R_{m a x} = 0.5 \cdot 15339 = 7670$  m, and  $radiusOnMax = 0.6$  at 15339 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{15000 - 7670}{15339 - 7670} = 0.5956$ , so  $σ_{V} = σ_{H} \cdot k = 136.5 \cdot 0.5956 = 81.3 m$ .

AP pen 5 km211 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2692 \cdot 59^{0.69} \cdot {0.152}^{- 1.07} \cdot {563.2}^{1.38} = 211 mm$ , where 563.2 m/s is the shell's speed when it arrives at 5 km (from 762 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 km143 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2692 \cdot 59^{0.69} \cdot {0.152}^{- 1.07} \cdot {424.8}^{1.38} = 143 mm$ , where 424.8 m/s is the shell's speed when it arrives at 10 km (from 762 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 km107 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2692 \cdot 59^{0.69} \cdot {0.152}^{- 1.07} \cdot {344.1}^{1.38} = 107 mm$ , where 344.1 m/s is the shell's speed when it arrives at 15 km (from 762 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 km6.53 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3225 \cdot {0.152}^{2}}{8 \cdot 59} = 4.96 \times 10^{- 5}$ . That runs from a 762 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 km6.44 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3 \cdot {0.152}^{2}}{8 \cdot 47.6} = 5.72 \times 10^{- 5}$ . That runs from a 812 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)12

6 mounts × 2 barrels = 12; all 12 bear on the broadside.

Model inputs

Krupp (AP)2,692

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 mass59 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 coefficient0.3225

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

AP muzzle velocity762 m/s

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

HE muzzle velocity812 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.

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.

radiusOnZero0.2

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 range76

Only families that reach 6 km contribute at the outer edge of the AA bubble. In-game families: 3in50 Twin Mark 33 11x2 -> 418 DPS @ 5 km; 3in50 MK34 Radar 2x1 -> 76 DPS @ 5 km; 20mm Oerlikon MK20 Twin12 12x2 -> 119 DPS @ 2 km; Far AA (?) -> 76 DPS @ 6 km.

AA DPS layered by range76 DPS @ 6 km, 570 DPS @ 5 km, 689 DPS @ 2 km

@ 6 km: 76 from one family; @ 5 km: 418 + 76 + 76 = 570; @ 2 km: 418 + 76 + 119 + 76 = 689. 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-blank689

418 + 76 + 119 + 76 = 689 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index3164

418 × 5 + 76 × 5 + 119 × 2 + 76 × 6 = 3164. 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

Designed as an AA cruiser with dual-purpose 152 mm guns. Though classified as light cruisers, ships of this class had increased displacement and dimensions, compared with the Baltimore-class heavy cruisers. The main twin turrets were equipped with advanced autoloaders, substantially increasing the rate of fire.

Armor Beta

Hull HP 45,400, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds.

Bow & stern32 mm

Overmatched by 7 AP guns here: Incomparable SE 25IncomparableYamato and 4 more. Angling still helps against the rest.

Belt / citadel127 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 30s. Range-by-range in the Compare tool →

Stern	32 mm primary (range 6–102 mm)	3,600 (8% of HP)	Overmatched by 460mm+ AP (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+	Mirror of bow. Same fast saturation.
Citadel	127 mm primary (range 25–127 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	16 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).
Turret (module, per magazine)	separate HP pool, does not drain ship HP	22,700 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 (76 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	13,600 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.
