Karlsruhe is a Tier III German light cruiser whose 150mm guns earn citadels on broadsides (188,136 AP DPM), with Sonar as her vision tool: Hydro lets her contest islands and smoke without exposing the hull. HE pen sits at the 1/4 caliber ratio instead of the standard 1/6, so HE spam is a real damage option here - pens roughly 1.5x more armor than a same-caliber peer's HE round. Standout traits: best Sonar ship range in T3 CAs (5 km) and best Sonar torpedo range in T3 CAs (3.5 km).
Sit 10-13 km from a contested cap where an island shadows you from the opposite battleship line. Hydro (5 km on ships, 3.5 km on torpedoes) lights up DDs and incoming torpedoes inside its bubble, so you can push the cap edge from cover without taking the spotting cycle; prefer cover positions over open-water flanks. 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 150mm shells citadel cruisers on the wrong frame, and her 22,700-HP hull does not recover from a punished salvo. Pick rotations and angles deliberately; the chip-damage role pays better than the trade-blow role on a cruiser of this profile.
90.0 mm armor deck, best of T3 CAs. Eats plunging fire and HE that peers don't.
6.0 AA DPS, bottom decile of T3 CAs. Aircraft chew through with impunity; lean on positioning over AA.
27.5 kt, bottom decile of T3 CAs. Hard to rotate flanks or disengage; commit positioning early.

Not standouts for Karlsruhe -- here's where she sits on every other ranked stat in the cohort. Stats tagged NORM are tied across more than half the cohort, so the value is the cohort default rather than a standout.

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model: $\sigma_H = \left(\dfrac{R}{30}\cdot\dfrac{\text{idealRadius}-\text{minRadius}}{\text{idealDistance}} + \text{minRadius}\right)\cdot 30$ $= \left(\dfrac{11479}{30}\cdot\dfrac{8-1.1}{1000} + 1.1\right)\cdot 30 = 112.2\,\text{m}$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.Vertical dispersion ellipse height at max range: $\sigma_V = \sigma_H \cdot \text{radiusOnMax}$ $= 112.2 \cdot 0.6 = 67.3\,\text{m}$How tall the same scatter ellipse is at 10 km. Comparable from ship to ship for the same reason as the width value above.50%-hit horizontal radius: $\sigma_{H,50} = \sigma_H \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 112.2 \cdot 0.32\;(\sigma = 2) = 35.9\,\text{m}$50%-hit vertical radius: $\sigma_{V,50} = \sigma_V \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 67.3 \cdot 0.319\;(\sigma = 2) = 21.5\,\text{m}$Standard cruiser dispersion baseline.Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity: $P = 10^{-7}\cdot K \cdot m^{0.69} \cdot d^{-1.07} \cdot v_0^{1.38}$ $= 10^{-7}\cdot 1925 \cdot 45.3^{0.69} \cdot 0.15^{-1.07} \cdot 835^{1.38} = 219.1\,\text{mm}$. Matches the in-game spec card.Same formula at the ship's max firing range (15.8 km), where the shell has slowed to 261.4 m/s: $P = 10^{-7}\cdot 1925 \cdot 45.3^{0.69} \cdot 0.15^{-1.07} \cdot 261.4^{1.38} = 44.1\,\text{mm}$.38 mm ≈ 150 mm caliber / 4 (improved HE penetration: German BBs, Yamato-class, and a handful of others).This ship's HE shells use a 1/4 (~0.25) caliber-to-pen ratio instead of the standard 1/6 (~0.167) - 0.253 in this case. Lets HE pen ~37mm armor instead of ~25mm. Hits every German cruiser (150mm CL, 203mm CA) and BB (350mm+), British heavy cruisers / Lion / Nelson, a handful of other premiums.floor(150 mm caliber / 14.3) = 10 mm (AP auto-penetrates plating this thick or less).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).

Here: (2×3.5×0.9) = 6. Covers AA-only mounts plus dual-purpose secondaries (Bismarck 105mm, USN 5"/38 cruiser secondaries) and dual-purpose main batteries (Sumner-class 5"/38, Akizuki-line 100mm). Formula validated against in-game captures on California, Sumner, Manfred von Richthofen, Dante Alighieri (exact) and within +/-17% on the remaining verified ships.Longest-reaching aura across AA-only + dual-purpose auras.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.Max dispersion = range (km) × 57 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.3.5 km × 57 + 30 = 229.5 m.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: 2×1 88 mm (1/side) × 60/4 × 1000 = 15,000.

Best on this ship: 4% from the 88 mm family.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: 15 mm from the 88 mm family.Hull HP 19,700 → 22,700 with hull upgrade, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are the exact in-game values, not estimated.
Overmatched by 95+ guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.
Thin belt: battleship AP citadels straight through it broadside. Rely on angle, speed and concealment, never sit flat.
Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 10%, fires burn 30s. Range-by-range in the ballistics tool →

An AP citadel penetration deals the shell's full damage, the biggest single hit available; only over-penetrations are damped, to ×0.10. |
| Superstructure | 10 mm primary (range 10–100 mm) | 1,100 (5% 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 | 11,400 magazine HP | Magazine detonation1–30% chance · below ~75% HP | Per-turret powder-magazine HP. Detonation chance scales from 1% (no mag damage) to 30% (full mag damage); this range is the in-game value. Detonation can't roll while the ship is above ~75% HP (the standard detonation-protection threshold, not a per-ship stat). Smaller magazines saturate to the 30% ceiling faster. |
| Secondary mount (88 mm mount) | separate HP pool, does not drain ship HP | 800 per-mount HP | Destroyed at 0 HP | Per-mount HP for the heaviest secondary on this ship. A mount destroyed at 0 HP is out for the rest of the battle; DCP does not repair destroyed mounts. Smaller (lighter-caliber) secondaries typically share the same HP value. |
| Rudder (module) | separate HP pool, does not drain ship HP | 6,800 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.
