Overview

Błyskawica '44 is a Pan-European Tier VII destroyer built around a fast-firing gun line that shoots AP only. Eight 102 mm barrels, tied for the most in her cohort, on a 4.0 s reload give her 222,000 AP damage per minute, 8th at her tier. Her shells are hard to bounce: they start to ricochet only at 60 degrees (tied best) and always ricochet only at 75 degrees, best at her tier, while a 12 mm fuse threshold, the lowest at her tier, arms them on light plating. The trade is a small 1,850 damage per shell and just 136.9 mm of close-range penetration, near the bottom of her tier.

Positioning

Fight in the band between her 7.01 km detection and her 10.9 km gun range, and aim at superstructures and destroyers rather than battleship belts. Keep islands between her and enemy cruisers, since 18,500 HP is only mid-pack. Sonar reaches ships at 5.0 km, tied 4th among the destroyers that carry it, and runs 100 s on a 120 s reload, so time it for contested caps. Engine Boost adds 9.8 knots to a 39 knot top speed, tied for the 2nd-largest gain, and 12 km torpedoes at 76 knots cover her exit.

Potato Avoidance

Burning Engine Boost to charge into a knife fight

The boost lasts only 60 s, among the shortest at her tier, and once it ends she is sluggish: 19.8 s to reach 90 percent speed is 6th-slowest at her tier and her 4.6 s rudder shift is also 6th-slowest. With 7.01 km detection, worse than the 6.94 km median, and torpedoes that hit for only 9,800 (near the bottom of her tier), she cannot win the close fight she started. Boost to reposition, not to commit.

Builds

Invest first in what feeds her guns: reload and AP damage output, because damage per minute is her main threat and each shell hits for only 1,850. Survivability and concealment come next, since 18,500 HP and 7.01 km detection leave little margin. Torpedo upgrades are a low priority on fish that hit for 9,800. Check current picks in the Build Tool before committing points.

Torp Reduction

1 − 0.333 hull torpedo-damage coefficient / 0.333 unprotected baseline = 0%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.

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.

5,600

Effective HP

Base 18,500 HP plus everything Repair Party can restore: 0.005 of max HP per second (0.5%) × 28 s × 18,500 HP = 2,590 HP per charge, × 2 charges = 5,180 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 × 2,800 = 5,600), 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. 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.

2,800

Casemate 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).

No saturation cap

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 × 13,900 = 27,800), 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.

13,900

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 × 1,200 = 2,400), 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.

1,200

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 × 1,500 = 3,000), 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.

Projectile speed76.0 kt

Range12 km

Maximum simulated damage

Most targets only intersect one hull section, so a hit transfers about 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 = 29, 400 \cdot 0.333 = 9, 800

. In battle, a hit on the torpedo belt deals the per-hit figure × (1 − the target's torpedo protection %), a bow or stern hit deals it in full, and a torpedo never counts as a citadel hit.

≈ 9,800

Maximum damage (ammunition)

29,400 warhead alpha / 3 + 900 blast = 10,700. Warhead alpha / 3 plus the blast addend: the per-torpedo damage figure. The 'Maximum simulated damage' row above applies target geometry to the same warhead.

10,700

Torpedo module damage

Per-torpedo module/blast damage parameter. 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.

900

Torpedo detectability1.6 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{1.6 km}{76 kt \times 2.6855} = 7.8 s

. 2.6855 converts knots to m/s on the game clock. Base value; commander torpedo-concealment skills lower it further.

7.8 s

Flooding chance

This torpedo carries a flooding-chance value of 1.73 per hit, shown as

1.73 \times 100 = 173 %

. 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.

AA explosions

Each ~2 s salvo fires 2 AA explosions in quick succession, each leaving 2 clouds ahead of the attacking squadron - up to 4 clouds per salvo × 190 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, 2 clouds each

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 salvo. Often called flak 'hit chance', but spawned clouds always damage planes that fly into them - the roll is on spawning.

Salvo interval

A new flak salvo (the AA explosions above) fires roughly 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 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.

Main battery formulas

vs standard DDStandard

The standard destroyer dispersion curve.

Shell scatter width @ 5 km52.5 m

(166.7 × (8 − 0.5) / 1000 + 0.5) × 30 = 52.5 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 km90 m

(333.3 × (8 − 0.5) / 1000 + 0.5) × 30 = 90 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 height @ 5 km25 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  $delim \cdot R_{m a x} = 0.5 \cdot 10852 = 5426$  m, and  $radiusOnMax = 0.6$  at 10852 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{5426} = 0.4764$ , so  $σ_{V} = σ_{H} \cdot k = 52.5 \cdot 0.4764 = 25 m$ .

Shell scatter height @ 10 km52.6 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  $delim \cdot R_{m a x} = 0.5 \cdot 10852 = 5426$  m, and  $radiusOnMax = 0.6$  at 10852 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 5426}{10852 - 5426} = 0.5843$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5843 = 52.6 m$ .

AP pen 5 km92 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 1789 \cdot 19^{0.69} \cdot {0.102}^{- 1.07} \cdot {538.8}^{1.38} = 92 mm$ , where 538.8 m/s is the shell's speed when it arrives at 5 km (from 811 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 km55 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 1789 \cdot 19^{0.69} \cdot {0.102}^{- 1.07} \cdot {369.9}^{1.38} = 55 mm$ , where 369.9 m/s is the shell's speed when it arrives at 10 km (from 811 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 km6.9 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.312 \cdot {0.102}^{2}}{8 \cdot 19} = 6.71 \times 10^{- 5}$ . That runs from a 811 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)8

4 mounts × 2 barrels = 8; all 8 bear on the broadside.

Model inputs

Krupp (AP)1,789

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 mass19 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 coefficient0.312

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

AP muzzle velocity811 m/s

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

idealRadius8

Horizontal dispersion growth per idealDistance of range, in 30 m units; the slope of the scatter-width line.

minRadius0.5

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.

Torpedoes

Estimated torpedo reaction time7.8 s

1600 m / (76.0 kt × 2.6855) = 7.8 s. detectability / (speed kt x 2.6855 m/s per knot on the game clock).

Torpedo speed76.0 kt

Travel time to max range58.8 s

12000 m / (76.0 kt × 2.6855) = 58.8 s. range / (speed kt x 2.6855 m/s per knot on the game clock).

Tube count6

2 launchers × 3 tubes.

Per-side salvo6 torpedoes

2 launchers × 3 tubes = 6, all to either side (centreline launchers train across - full salvo to either side).

Full-salvo damage58,800

All tubes hitting one target: tubes x per-torpedo simulated damage = 6 x 9,800 = 58,800. Each hit on the target's torpedo belt is reduced by its torpedo protection %.

AA defense

AA DPS at max range60

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors Mk1 2x2 -> 53 DPS @ 3.5 km; 303 Lewis 2x2 -> 10 DPS @ 1 km; 20mm Oerlikon MK4 4x1 -> 37 DPS @ 2 km; Far AA (?) -> 60 DPS @ 5 km.

AA DPS layered by range60 DPS @ 5 km, 113 DPS @ 3.5 km, 150 DPS @ 2 km, 160 DPS @ 1 km

@ 5 km: 60 from one family; @ 3.5 km: 53 + 60 = 113; @ 2 km: 53 + 37 + 60 = 150; @ 1 km: 53 + 10 + 37 + 60 = 160. 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-blank160

53 + 10 + 37 + 60 = 160 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (1 km).

AA threat index570

53 × 3.5 + 10 × 1 + 37 × 2 + 60 × 5 = 570. 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

A large destroyer with powerful armament, built at the British shipyard in Cowes. In World War II, ORP Błyskawica supported Allied actions in Norway and during the Dunkirk evacuation. In May 1942, she defended her home shipyard from a Luftwaffe raid. During the Normandy Landings, the destroyer participated in the Battle of Ushant. Today, ORP Błyskawica is a museum ship at the Naval Museum in Gdynia, Poland.

Armor Beta

Hull HP 18,500, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are estimates.

Bow & stern19 mm

Overmatched by 137+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Farming13 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	19 mm primary (range 19–20 mm)	≈ 925 (~5% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)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	≈ 13,875 (~75% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)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)	≈ 925 (~5% of HP)	Overmatched by 283mm+ AP (Scharnhorst, Scharnhorst '43)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	13 mm primary (range 13–19 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.
