Overview

Karl von Schönberg is a Tier VII German gunboat destroyer: her damage comes from sustained main battery pressure on caps and open-water trades. Torpedoes are a secondary threat for closing lanes, not her main damage. Her 150mm guns hit harder per shell than the 120-130mm most of the cohort brings, and a 4.5 s reload means straight trades favour her. Standout traits: best HE alpha in T7 DDs (2,200) and best AP fuse timer in T7 DDs (0.03 s).

Positioning

Hold mid-cap distance and lean into gunboat trades from cover where the peer destroyer cannot match your fires-per-minute. Avoid open-water duels with ships running smoke or radar; the torpedoes are a closer, not the plan, so gunfire from cover wins more than from blue water. Concretely: 11.2 km of reach against 6.8 km of detection leaves about 4.3 km in which you can shoot before the answer arrives. 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. Shooting from the cloud gives you away at 3 km, and a destroyer here is spotted at about 7 km, so you see it coming with roughly 4 km to spare. Vision is mutual: past the 2 km guaranteed ring you cannot see out either, and only your Sonar bubble (5.6 km) sees out; past that you are shooting at what a teammate holds lit. Enemy sonar (about 4.4 km) and radar (about 9.5 km) read straight in regardless. A 690 m turning circle is wide for her cohort, so a committed turn gives up a lot of water; plan course changes a salvo ahead.

Potato Avoidance

Burning Main Battery Reload Booster on a hopeful salvo

With only 2 charges it is a finisher rather than an opener: spend it on a target that cannot turn away, a broadside battleship or a cruiser already committed to its own attack, where the extra salvo lands as damage instead of splashes. A booster pressed on a maybe is one you will not have when the certainty shows up.

Signature Traits

Improved HE penetration

HE pen at the 1/4 caliber ratio instead of the standard 1/6. HE-spam is a real damage option here, not just a fire-starter, shared by 6/40 T7 DDs.

Engine Boost

+8% speed (about +2.9 kt), 120 s duration. Engine Boost consumable gives a small speed nudge - useful for closing a gap or steadying a torpedo run, not for running anything down.

Fire resistance

Does not reduce the damage a burning fire does per second: replay-measured burn ticks run at the full rate on every ship. By elimination it lowers how often hits set you on fire; ignition-rate replay data is consistent with that but too confounded by attacker mix to measure the reduction directly.

36.6%

Fire duration30 s

Fire damage

Each fire ticks 0.3% of max HP per second for the full 30 s, so one unattended fire burns 9% of the pool (2,025 HP on this ship). 4 fire points can burn at once. Verified against measured burn ticks in replay data.

0.3% of HP per second

Flood duration40 s

Flood damage

A flood ticks 0.25% of max HP per second for the 40 s duration, so one unattended flood costs 10% of the pool (2,250 HP on this ship). Verified against measured flood ticks in replay data.

0.25% of HP per second

Torp Reduction

Reduces torpedo hit damage. Replay data shows no effect on floods: flood ticks run at the full rate and flood frequency does not decline with protection.

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.

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.

How far each mount can train, in degrees to either side of the mount's own facing, read from in-game data. 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.

±150°, 2x ±148°, ±141°

Guns to bear

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. Mount facing is inferred from turret stations and verified against known layouts, including Izumo's aft-facing forward turret.

= 10^{- 7} \cdot 1933 \cdot {45.3}^{0.69} \cdot {0.15}^{- 1.07} \cdot 835^{1.38} = 220 mm

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 = 38, 100 \cdot 0.333 = 12, 700

≈ 12,700

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 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}{58 kt \times 2.6855} = 8.3 s

. The 2.6855 m/s-per-knot game-speed factor is calibrated from in-game measurement; the community's traditional 2.6 reads about 3% slower. Base value; commander torpedo-concealment skills lower it further. Community torpedo-reaction calculator by u/LorenDovah and u/The_ColorOutofSpace.

8.3 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 2.27 per hit, shown as

2.27 \times 100 = 227 %

. 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.

13.9 kt

Crash stop

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. Same community-model simulation as the acceleration times, using the ship's own reverse-power ratio from in-game data. The full curve is on the acceleration chart.

13 s

Engine boost threshold (reverse)

Speed below which the engine's built-in power boost applies in reverse. Matches the in-game maneuverability card's reverse threshold (Vampire II reads 10.5 here and the card shows 11; the card rounds half up).

11 kt

Acceleration 0-90%

Time to reach 90% of top speed (32.4 kt of 36 kt), from our in-house acceleration model.

15.7 s

Acceleration 0-99%

Time to reach 99% of top speed (35.6 kt of 36 kt). 99% rather than 100% because true top speed is asymptotic (thrust meets drag), so the last fraction of a knot is never quite gained.

26.4 s

Traverse-to-turn ratio

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

ω_{hull} = \frac{180}{π} \cdot \frac{V_{max} (m/s)}{R_{turn}} = \frac{180}{π} \cdot \frac{36.0 \cdot 0.5144}{690} = 1.54 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{11}{1.54} = 7.2 \times

. Below 5 the turrets drag in a turning fight; 25+ keeps up with any rudder.

Shell Grouping (σ)2

Max Horiz Disp99 m at 11.2 km

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{11200}{30} \cdot \frac{8 - 0.5}{1000} + 0.5) \cdot 30 = 99 m$

Shell scatter width @ 5 km52.5 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 km90 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 Disp59.4 m at 11.2 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 99 \cdot 0.6 = 59.4 m$

Shell scatter height @ 10 km52.1 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  $delim \cdot R_{m a x} = 0.5 \cdot 11200 = 5600$  m, and  $radiusOnMax = 0.6$  at 11200 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 5600}{11200 - 5600} = 0.5786$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5786 = 52.1 m$ .

AP Pen Far75.2 mm at 11.2 km

Same formula at the ship's max firing range (11.2 km), where the shell has slowed to 383.7 m/s:  $P = 10^{- 7} \cdot 1933 \cdot {45.3}^{0.69} \cdot {0.15}^{- 1.07} \cdot {383.7}^{1.38} = 75.2 mm$ .

AP pen 5 km133 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ .

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 km6.36 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.3059 \cdot {0.15}^{2}}{8 \cdot 45.3} = 5.97 \times 10^{- 5}$ . That runs from a 835 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 penetration38 mm

38 mm ≈ 150 mm caliber / 4 (improved HE penetration: German BBs, Yamato-class, and a handful of others).

Improved HE PenYes

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.

AP overmatch10 mm

floor(150 mm caliber / 14.3) = 10 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius12

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 alpha4

All 4 barrels bear on the broadside.

Turret turn time16.4 s

180 degrees / 11 deg/s traverse speed = 16.4 s.

3,800 AP damage x 4 broadside guns = 15,200.

HE DPMInitial: 105,600 → 117,333

Zero upgrades: 8,800 HE full-salvo alpha x 60 / 5 s base reload = 105,600. All upgrades (Main Battery Mod. 3 = -10% reload): 8,800 HE full-salvo alpha x 60 / 4.5 s all-upgrades reload = 117,333.

AP DPMInitial: 182,400 → 202,667

Zero upgrades: 15,200 AP full-salvo alpha x 60 / 5 s base reload = 182,400. All upgrades (Main Battery Mod. 3 = -10% reload): 15,200 AP full-salvo alpha x 60 / 4.5 s all-upgrades reload = 202,667.

Shells/minInitial: 48 → 53.3

Zero upgrades: 4 broadside guns x 60 / 5 s base reload = 48. All upgrades (Main Battery Mod. 3 = -10% reload): 4 broadside guns x 60 / 4.5 s all-upgrades reload = 53.3.

Fires/minInitial: 5.28 → 5.87

Zero upgrades: 48 shells/min x 11% fire chance = 5.28. All upgrades (Main Battery Mod. 3 = -10% reload): 53.3 shells/min x 11% fire chance = 5.87.

Torpedoes

Torpedo detectability1.3 km

Estimated torpedo reaction time8.3 s

detectability / (speed kt x 2.6855 game-speed factor, m/s per knot, calibrated from in-game measurement; the community's traditional 2.6 reads about 3% slower).

Torpedo speed58 kt

Travel time to max range54.6 s

range / (speed kt x 2.6855 game-speed factor, m/s per knot, calibrated from in-game measurement).

Torpedo module damage1,000

Per-torpedo module/blast damage parameter from in-game data. 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; the exact module-HP conversion is not published.

Tube count8

2 launchers x 4 tubes.

Per-side salvo8 torpedoes

8 (centerline launchers train across - full salvo to either side).

Full-salvo damage101,600

All tubes hitting one target: tubes x per-torpedo simulated damage = 8 x 12,700 = 101,600.

Per-side salvo damage101,600

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 8 x 12,700 = 101,600.

AA defense

AA DPS at max range42

Only families that reach 3.5 km contribute at the outer edge of the AA bubble. In-game families: 37mm Flak M42 LM43 2x1 -> 42 DPS @ 3.5 km; 20mm Flak 38 4x1 -> 57 DPS @ 2 km; 20mm Flack 38 quad 4x4 -> 57 DPS @ 2 km.

Maximum AA range3.5 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 @ 3.5 km, 156 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-blank156

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

AA threat index375

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 22,500, 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.

Bow & stern16 mm

Overmatched by 141+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Farming10 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	16 mm primary (range 15–16 mm)	3,100 (14% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)Angle bounces 203mm16 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)	16 mm primary (range 13–16 mm)	16,900 (75% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)Angle bounces 203mm16 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	16 mm primary (range 13–16 mm)	1,800 (8% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)Angle bounces 203mm16 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	16 mm primary (range 15–16 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	10 mm	1,800 (8% 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	9,000 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 (37 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	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.
