Overview

Christopher is a Tier VIII American super-radar destroyer (9 km) and an equal 9 km torpedo-detection radius so the same scan that lights an enemy DD also paints incoming torps. The kit isn't stealth-and-ambush -- the radar IS the kit; she takes caps by lighting up the contest from inside her own scan, not by sneaking in under detection. Standout traits: best HE alpha in T8 DDs (2,200) and best AP always-pen window in T8 DDs (60°).

Positioning

Hold a flank position your team can rotate behind, not a center lane your team has to defend you in. 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.

Potato Avoidance

Idling beam-on in an obvious torpedo lane

Unspotted is not unseen: once the enemy has reason to think a destroyer is holding this cap they will put torpedoes into the water you are probably in, and one fish the size of your own (25,000 damage against 20,700 HP) is more than your whole health bar. Keep way on, cross lanes bow or stern first, and never sit still beam-on to a chokepoint you would torpedo yourself.

Signature Traits

Surveillance Radar

9 km range, 12 s duration. Detects all enemy ships within a fixed radius regardless of line-of-sight. Controls caps and punishes smoke-firing DDs.

ELITE MAIN BATTERY ↗

Heavy HE shells · 2200 damage
Wide always-pen zone · 60°
Late auto-bounce · 67.5°

Heavy torpedoes ↗

25000 damage per torpedo, best of T8 DDs.

Long-range radar ↗

9 km Surveillance Radar range, best of the 4 T8 DDs with radar. Lights targets peer radars can't reach.

Lingering smoke ↗

124 s smoke cloud linger, top decile of T8 DDs. Each puff stays up longer after you stop laying it, holding the shield.

Stiff AP fuse ↗

23 mm AP arming threshold, bottom decile of T8 DDs. Over-pens thin plates; the trade-off pays off when most targets are battleship belt armor.

P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}

= 10^{- 7} \cdot 2600 \cdot 34^{0.69} \cdot {0.137}^{- 1.07} \cdot 930^{1.38} = 310.4 mm

Range10 km

Maximum simulated damage

Estimate of WG's in-game value; matches the in-game port screen within ±5%. Saturation: most targets only intersect one hull section, so the sim transfers ~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 = 37, 500 \cdot 0.667 = 25, 000

≈ 25,000

Maximum damage (ammunition)

The ammunition card's 'Maximum Damage' stat, exact: warhead alpha / 3 plus the blast addend. This is the per-torpedo number most references quote; the 'Maximum simulated damage' row above is WG's separate geometry-sim stat from the launcher spec panel.

Torpedo detectability0.9 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{0.9 km}{44 kt \times 2.6} = 7.9 s

, equivalently

5000 \times detectability / (13 \times speed)

. Base value; commander torpedo-concealment skills lower it further. Community torpedo-reaction calculator by u/LorenDovah and u/The_ColorOutofSpace.

7.9 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 2.59 per hit, shown as

2.59 \times 100 = 259 %

. Torpedo flood 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. Not shown on the in-game port screen.

Bursts

Each ~2 s wave fires 2 quick salvos of 1 clouds ahead of the attacking squadron - up to 2 clouds per wave × 240 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

Every potential cloud spawns - the full pattern, every wave. 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 main battery mount is operational - even losing every other 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 bursts can land short of 2.5 km or past 5 km - once planes get inside the band, new waves stop.

Traverse-to-turn ratio

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

Shell Grouping (σ)2

Max Horiz Disp74.7 m

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{11198}{30} \cdot \frac{6 - 0.4}{1000} + 0.4) \cdot 30 = 74.7 m$

Shell scatter width @ 5 km40 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 km68 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.

Max Vert Disp44.8 m

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 74.7 \cdot 0.6 = 44.8 m$

Shell scatter height @ 10 km39.3 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  $delim \cdot R_{m a x} = 0.5 \cdot 11198 = 5599$  m, and  $radiusOnMax = 0.6$  at 11198 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 5599}{11198 - 5599} = 0.5786$ , so  $σ_{V} = σ_{H} \cdot k = 68 \cdot 0.5786 = 39.3 m$ .

Med Horiz Disp22.4 m

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 74.7 \cdot \frac{0.6}{2} = 22.4 m$

Med Vert Disp13.4 m

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 44.8 \cdot \frac{0.6}{2} = 13.4 m$

AP Pen Close310.4 mm

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2600 \cdot 34^{0.69} \cdot {0.137}^{- 1.07} \cdot 930^{1.38} = 310.4 mm$ . Matches the in-game spec card.

AP Pen Far78.1 mm

Same formula at the ship's max firing range (14 km), where the shell has slowed to 342.3 m/s:  $P = 10^{- 7} \cdot 2600 \cdot 34^{0.69} \cdot {0.137}^{- 1.07} \cdot {342.3}^{1.38} = 78.1 mm$ .

AP pen 5 km182 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 km106 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.

HE flight time @ 10 km6.11 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2377 \cdot {0.137}^{2}}{8 \cdot 34} = 5.15 \times 10^{- 5}$ . 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: 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.

AP flight time @ 10 km5.87 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.2941 \cdot {0.137}^{2}}{8 \cdot 34} = 6.38 \times 10^{- 5}$ . That runs from a 930 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 penetration23 mm

23 mm ≈ 137 mm caliber / 6 (standard HE penetration ratio).

AP overmatch9 mm

floor(137 mm caliber / 14.3) = 9 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius16

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.

Broadside guns used for alpha6

All 6 barrels bear on the broadside.

Turret turn time14.4 s

180 degrees / 12.5 deg/s traverse speed = 14.4 s.

HE full-salvo alpha13,200

2,200 HE damage x 6 broadside guns = 13,200.

AP full-salvo alpha20,400

3,400 AP damage x 6 broadside guns = 20,400.

HE DPMInitial: 113,143 → 134,237

Zero upgrades: 13,200 HE full-salvo alpha x 60 / 7 s base reload = 113,143. All upgrades (top gun + Main Battery Mod. 3 = -10% reload): 13,200 HE full-salvo alpha x 60 / 5.9 s all-upgrades reload = 134,237.

AP DPMInitial: 174,857 → 207,458

Zero upgrades: 20,400 AP full-salvo alpha x 60 / 7 s base reload = 174,857. All upgrades (top gun + Main Battery Mod. 3 = -10% reload): 20,400 AP full-salvo alpha x 60 / 5.9 s all-upgrades reload = 207,458.

Shells/minInitial: 51.4 → 61

Zero upgrades: 6 broadside guns x 60 / 7 s base reload = 51.4. All upgrades (top gun + Main Battery Mod. 3 = -10% reload): 6 broadside guns x 60 / 5.9 s all-upgrades reload = 61.

Fires/minInitial: 4.63 → 5.49

Zero upgrades: 51.4 shells/min x 9% fire chance = 4.63. All upgrades (top gun + Main Battery Mod. 3 = -10% reload): 61 shells/min x 9% fire chance = 5.49.

Full-salvo damage125,000

All tubes hitting one target: tubes x per-torpedo simulated damage = 5 x 25,000 = 125,000.

Per-side salvo damage125,000

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 5 x 25,000 = 125,000.

AA defense

AA DPS at max range42

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors Mk1 4x2 -> 102 DPS @ 3.5 km; 40mm Bofors Mk2 4x4 -> 102 DPS @ 3.5 km; 20mm Oerlikon Twin 6x2 -> 80 DPS @ 2 km; Far AA (?) -> 42 DPS @ 5 km.

Maximum AA range5 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 range42 DPS @ 5 km, 246 DPS @ 3.5 km, 326 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-blank326

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

AA threat index1084

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

Armor Beta

Hull HP 18,700 → 20,700 with hull upgrade, 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 & stern19 mm

Overmatched by 132+ guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Farming19 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 →

Section	Plates	HP cap	Threats	Tactic
Bow	19 mm primary (range 19–20 mm)	≈ 1,035 (~5% of HP)	Overmatched by 283mm+ (Scharnhorst '43, Schill)Angle bounces 203mm19 mm: HE pens from 127mm+	Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.
Hull (midship)	19 mm	≈ 15,525 (~75% of HP)	Overmatched by 283mm+ (Scharnhorst '43, Schill)Angle bounces 203mm19 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	19 mm primary (range 19–20 mm)	≈ 1,035 (~5% of HP)	Overmatched by 283mm+ (Scharnhorst '43, Schill)Angle bounces 203mm19 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	20 mm primary (range 13–20 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	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.
