Overview

Celtic is a Tier VII British cruiser built around the super-heal: each Repair Party charge returns dramatically more HP than a standard heal, so her durability comes from sustain rather than armor. Surveillance Radar (9.9 km, 25 s active, every 180 s) is the cap-control consumable on top, so she sets fights as well as winning them. AA (540 AA DPS at 5 km, +100% Defensive AA flak burst) ranks 5 of 58 in T7 CAs: heavy enough to make a careless strike expensive, though not the umbrella that shuts a carrier out of her grid. Standout traits: deep effective HP in T7 CAs (66,060, 6th of 57) and fast heal cycle in T7 CAs (17,616 HP, 2nd of 57). The trade is soft superstructure in T7 CAs (6 mm, 48th of 53).

Positioning

Hold cover beside a contested cap, close enough that an island can break sightline when focus shifts. Radar reaches 9.9 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. The helm answers quickly (7.1 s), so she can break an incoming salvo that slower hulls have to eat.

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 9.9 km for 25 s, which is the whole window your team gets to act on what it shows.

Signature Traits

Surveillance Radar

9.9 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 − 0.6337 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 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 × 36,700 HP = 3,303 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 × 36,700 HP = 3,670 HP on this ship.

0.25% of HP per second

Torp Reduction

1 − 0.32 hull torpedo-damage coefficient / 0.333 unprotected baseline = 4%. 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.

21,200

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.

12,700

Effective HP

Base 36,700 HP plus everything Repair Party can restore: 0.02 of max HP per second (2%) × 20 s × 36,700 HP = 14,680 HP per charge, × 2 charges = 29,360 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 × 1,600 = 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

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 × 6,600 = 13,200), 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.

Damage saturation pool for the hull: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 31,800 = 63,600), 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.

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.

31,800

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 × 1,600 = 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 ×. 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.

1,600

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 × 2,900 = 5,800), 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.

2,900

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.

3x ±150°

Guns to bear

180° − 150° (the most restricted aft-facing mount's arc) = 30° 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 × 230 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.

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.

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.

Per-family: 6×2 127 mm (6/side) × 60/6 s × 1800 = 108,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

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.

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 km26.6 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  $delim \cdot R_{m a x} = 0.5 \cdot 15470 = 7735$  m, and  $radiusOnMax = 0.6$  at 15470 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{7735} = 0.3939$ , so  $σ_{V} = σ_{H} \cdot k = 67.5 \cdot 0.3939 = 26.6 m$ .

Shell scatter height @ 10 km54 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  $delim \cdot R_{m a x} = 0.5 \cdot 15470 = 7735$  m, and  $radiusOnMax = 0.6$  at 15470 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7735}{15470 - 7735} = 0.5293$ , so  $σ_{V} = σ_{H} \cdot k = 102 \cdot 0.5293 = 54 m$ .

Shell scatter height @ 15 km81.1 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:  $radiusOnZero = 0.2$  at 0 m,  $radiusOnDelim = 0.5$  at  $delim \cdot R_{m a x} = 0.5 \cdot 15470 = 7735$  m, and  $radiusOnMax = 0.6$  at 15470 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{15000 - 7735}{15470 - 7735} = 0.5939$ , so  $σ_{V} = σ_{H} \cdot k = 136.5 \cdot 0.5939 = 81.1 m$ .

AP pen 5 km322 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2846 \cdot 118^{0.69} \cdot {0.203}^{- 1.07} \cdot {651.8}^{1.38} = 322 mm$ , where 651.8 m/s is the shell's speed when it arrives at 5 km (from 853 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 km226 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2846 \cdot 118^{0.69} \cdot {0.203}^{- 1.07} \cdot {504.2}^{1.38} = 226 mm$ , where 504.2 m/s is the shell's speed when it arrives at 10 km (from 853 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 km167 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2846 \cdot 118^{0.69} \cdot {0.203}^{- 1.07} \cdot {405.6}^{1.38} = 167 mm$ , where 405.6 m/s is the shell's speed when it arrives at 15 km (from 853 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 km5.61 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.321 \cdot {0.203}^{2}}{8 \cdot 118} = 4.4 \times 10^{- 5}$ . That runs from a 853 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 km5.88 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.333 \cdot {0.203}^{2}}{8 \cdot 118} = 4.57 \times 10^{- 5}$ . That runs from a 823 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)2,846

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 mass118 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 coefficient0.321

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

AP muzzle velocity853 m/s

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

HE muzzle velocity823 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 range98

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors 12x4 -> 296 DPS @ 3.5 km; 20mm Oerlikon MK4 23x1 -> 146 DPS @ 2 km; 5in38 Mk32 Mod12 6x2 -> 98 DPS @ 5 km.

AA DPS layered by range98 DPS @ 5 km, 394 DPS @ 3.5 km, 540 DPS @ 2 km

@ 5 km: 98 from one family; @ 3.5 km: 296 + 98 = 394; @ 2 km: 296 + 146 + 98 = 540. 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-blank540

296 + 146 + 98 = 540 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index1818

296 × 3.5 + 146 × 2 + 98 × 5 = 1818. 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 firepower

Max HE alpha1800

The only family (127 mm): 1800. Maximum HE damage per shell across secondary HE families. Best on this ship: 1800 from the 127 mm family.

Max HE fire chance5%

The only family (127 mm): 5%. Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 5% from the 127 mm family.

Max HE pen21 mm

The only family (127 mm): 21 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: 21 mm from the 127 mm family.

Background

A well-guarded secret of the druids, Celtic is a rare sight on the seas. Seeing it, unlike the Flying Dutchman, heralds good luck!

Armor Beta

Hull HP 36,700, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are estimates.

Bow & stern27 mm

Overmatched by 69+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel152 mm

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

Farming6 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 37%, fires burn 30s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	27 mm primary (range 27–40 mm)	≈ 1,835 (~5% of HP)	Overmatched by 406mm+ AP (Colorado, Sinop)Angle bounces 380mm27 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)	27 mm primary (range 27–152 mm)	≈ 27,525 (~75% of HP)	Overmatched by 406mm+ AP (Colorado, Sinop)Angle bounces 380mm27 mm: HE pens from 203mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	27 mm primary (range 6–102 mm)	≈ 1,835 (~5% of HP)	Overmatched by 406mm+ AP (Colorado, Sinop)Angle bounces 380mm27 mm: HE pens from 203mm+	Mirror of bow. Same fast saturation.
Citadel	152 mm primary (range 6–160 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	6 mm primary (range 6–38 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.
