Overview

Furutaka is a Tier IV Japanese IJN cruiser with the improved AP fuse: her AP shells arm at 60% of the standard armor threshold, so they citadel cruisers that would over-pen a normal CA round. Her bounce angles are the standard ones though, and a shell that fails the angle check wastes its penetration entirely, so the fuse only pays off against a target that is genuinely flat. Pick targets by their angle, not by their health bar. Sonar (3.7 km on ships and 2.7 km on torpedoes, 90 s active, 180 s reload, long uptime) lights up DDs and torpedoes inside its bubble, which lets her contest the cap edge without taking the spotting cycle. Standout traits: best heavy AP shells in T4 CAs (4,700, 2nd of 23) and best AP overmatch threshold in T4 CAs (14.1 mm, 2nd of 23). The trade is low HE DPM in T4 CAs (87,537, 19th of 20).

Positioning

Work the islands rather than a firing line. Sonar (3.7 km on ships, 2.7 km on torpedoes) is the whole kit, and it only pays inside that radius, so hold the cover beside a contested cap and use it to catch destroyers and torpedoes coming around the corner: HE into the destroyer, AP into any cruiser that shows you a broadside while it sits in smoke. Firing from a friendly smoke reveals you at 5.9 km, so pick the salvo rather than holding the trigger. The helm answers fast (5.8 s) but the circle is wide (750 m): weave to spoil aim rather than committing to turns, because a committed turn gives up more water than the quick rudder saves you.

Potato Avoidance

Pushing in blind because the kit says brawler

3.7-km Sonar is what makes the close fight winnable, and it only helps once you are already committed; it does not tell you what is waiting two islands over. Push when a destroyer is lit or a teammate holds vision, not to find out who is there.

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.

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.

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 × 1,000 = 2,000), 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.

1,000

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 × 5,400 = 10,800), 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 ×.

Damage saturation pool for the hull: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 23,000 = 46,000), 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.

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.

23,000

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 × 1,900 = 3,800), 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 ×. 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.

1,900

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 × 900 = 1,800), 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.

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.

5x ±150°, 292° arc

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.

AP AOE Radius

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.

Torpedoes

ModuleTorpedoes: Type8 mod. 2

Launchers / tubes2 launchers × 4 tubes = 8 tubes

Reload time

Base reload of the top torpedo module (all-upgrades configuration); the stock module reloads in 73 s. Modernizations and commander effects scale it further, e.g. Torpedo Launchers Mod. 3 alone is x0.85:

94 \times 0.85 = 79.9

Initial: 73 s → 94 s

Projectile speed

Speed of the top torpedo module (all-upgrades configuration, 59.0 kt); the stock torpedo module runs 63.0 kt.

Initial: 63 kt → 59 kt

RangeInitial: 6 km → 9.99 km

Maximum simulated damage

Initial: 40,200 × 0.333 = 13,400 → 44,900 × 0.333 = 14,967 (warhead alpha × saturation coefficient, stock → upgraded torpedo). 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 = 44, 900 \cdot 0.333 = 14, 967

. 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.

Initial: ≈ 13,400 → ≈ 14,967

Maximum damage (ammunition)

44,900 warhead alpha / 3 + 1,300 blast = 16,267. 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.

16,267

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.

1,300

Torpedo detectability1.5 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{1.5 km}{59 kt \times 2.6855} = 9.5 s

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

9.5 s

Flooding chance

This torpedo carries a flooding-chance value of 2.69 per hit, shown as

2.69 \times 100 = 269 %

. 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 1 cloud ahead of the attacking squadron - up to 2 clouds per salvo × 150 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, 1 cloud each

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.

Flak keeps firing while at least one secondary battery mount is operational - even losing every dedicated AA mount does not stop it.

Secondary 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 4.5 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.

Shell Grouping (σ)1

Secondary DPM (per side)

Sum across all secondary families of (per-side barrels × 60 / reload_s × alpha), with each reload counted in whole 1/7 s ticks (guns fire on the first tick after the reload), where per-side barrels = mounts × barrels-per-mount / 2 (the guns that bear on one broadside target). Per-family: Initial: 4×1 76.2 mm (2/side) × 60/3.571 s (3.5 s = 25 ticks) × 1300 = 43,680 → 4×1 120 mm (2/side) × 60/5 s × 2000 = 48,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

Initial: 43,680 → 48,000

Secondary fire DPM vs T4 BB (per side)

Fires/min (per side) 1.9 × (1 − 0.166 fire resistance) × 60 s × 0.003 of max HP per second × 48,200 HP = 13,893. Per side: the barrels that bear on one broadside target (mounts × barrels / 2). A ceiling: assumes every shell hits and ignores the four-fire cap and Fire Prevention.

13,893

Total secondary DPM vs T4 BB (per side)

Secondary DPM (per side) 48,000 + secondary fire DPM 13,893 = 61,893: shell damage plus fire damage against one T4 battleship, every shell hitting.

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 height @ 5 km28.7 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  $delim \cdot R_{m a x} = 0.5 \cdot 13351.8 = 6676$  m, and  $radiusOnMax = 0.6$  at 13351.8 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{6676} = 0.4247$ , so  $σ_{V} = σ_{H} \cdot k = 67.5 \cdot 0.4247 = 28.7 m$ .

Shell scatter height @ 10 km56.1 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  $delim \cdot R_{m a x} = 0.5 \cdot 13351.8 = 6676$  m, and  $radiusOnMax = 0.6$  at 13351.8 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 6676}{13351.8 - 6676} = 0.5498$ , so  $σ_{V} = σ_{H} \cdot k = 102 \cdot 0.5498 = 56.1 m$ .

AP pen 5 km265 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2377 \cdot 110^{0.69} \cdot {0.2}^{- 1.07} \cdot {659.8}^{1.38} = 265 mm$ , where 659.8 m/s is the shell's speed when it arrives at 5 km (from 870 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 km184 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2377 \cdot 110^{0.69} \cdot {0.2}^{- 1.07} \cdot {506.7}^{1.38} = 184 mm$ , where 506.7 m/s is the shell's speed when it arrives at 10 km (from 870 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 km5.54 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.317 \cdot {0.2}^{2}}{8 \cdot 110} = 4.53 \times 10^{- 5}$ . That runs from a 870 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 km5.54 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.317 \cdot {0.2}^{2}}{8 \cdot 110} = 4.53 \times 10^{- 5}$ . That runs from a 870 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)6

6 mounts × 1 barrels = 6; all 6 bear on the broadside.

Model inputs

Krupp (AP)2,377

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 mass110 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 coefficient0.317

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

AP muzzle velocity870 m/s

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

HE muzzle velocity870 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.

Torpedoes

Estimated torpedo reaction time9.5 s

1500 m / (59.0 kt × 2.6855) = 9.5 s. detectability / (speed kt x 2.6855 m/s per knot on the game clock).

Torpedo speed59.0 kt

Travel time to max range63.1 s

9990 m / (59.0 kt × 2.6855) = 63.1 s. range / (speed kt x 2.6855 m/s per knot on the game clock).

Tube count8

2 launchers × 4 tubes.

Per-side salvo4 torpedoes

8 wing tubes / 2 = 4: the launchers sit one per beam, so only half of them reach any one side. Each launcher reloads on its own, so she can fire one beam, turn, and fire the other without waiting.

Full-salvo damage119,736

All tubes hitting one target: tubes x per-torpedo simulated damage = 8 x 14,967 = 119,736. Each hit on the target's torpedo belt is reduced by its torpedo protection %.

AA defense

AA DPS at max range22

Only families that reach 4.5 km contribute at the outer edge of the AA bubble. In-game families: 7 7mmLewis 2x1 -> 12 DPS @ 1 km; 13mm76 Type93 double 2x2 -> 24 DPS @ 1.2 km; 120mm45 Type HaGun 4x1 -> 22 DPS @ 4.5 km.

AA DPS layered by range22 DPS @ 4.5 km, 46 DPS @ 1.2 km, 58 DPS @ 1 km

@ 4.5 km: 22 from one family; @ 1.2 km: 24 + 22 = 46; @ 1 km: 12 + 24 + 22 = 58. 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-blank58

12 + 24 + 22 = 58 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (1 km).

AA threat index140

12 × 1 + 24 × 1.2 + 22 × 4.5 = 140. 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 range1.2 km

Secondary battery firepower

Max HE alpha2000

The only family (120 mm): 2000. Maximum HE damage per shell across secondary HE families. Best on this ship: 2000 from the 120 mm family.

Max HE fire chance8%

The only family (120 mm): 8%. Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 8% from the 120 mm family.

Max HE pen20 mm

The only family (120 mm): 20 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: 20 mm from the 120 mm family.

Background

A powerful scout cruiser employed to carry out reconnaissance operations and to protect battleship fleets from enemy light naval forces. Furutaka's primary distinction, from her predecessors, was an enhanced artillery armament featuring a pyramid arrangement of turret mounts.

Armor Beta

Hull HP 28,300 → 30,700 with hull upgrade, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds.

Bow & stern13 mm

Overmatched by 90+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel76 mm

Thin belt: battleship AP citadels straight through it broadside. Rely on angle, speed and concealment, never sit flat.

Turret (module, per magazine)	separate HP pool, does not drain ship HP	15,400 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.
Secondary mount (76.2 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.
AA mount (13 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	9,200 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.
