Overview

Aki SE 25 is the Legendary Japanese airstrike battleship. Her alt-armament fires a torpedo-bomber airstrike in place of shipborne torpedoes: the planes drop a spread of aerial torpedoes on the marked lane, a damage source that does not need line of sight on top of her main battery. Standout traits: best sigma in Legendary BBs (2.1, 2nd of 23) and main battery range in Legendary BBs (17.7 km, 4th of 23). The trade is AP DPM in Legendary BBs (190,286, 23rd of 23).

Positioning

Park 14-17 km from a contested cap with island cover within one rotation of your bow. The airstrike line wants to cross the cap and the predictable retreat lane, both of which favor positions a little further back than a brawler would take. Open-water lanes are pure downside; you do not need line of sight to score with the airstrike, so cover is free upside. Her handling reads as a contradiction and is not one: 19.2 s on the rudder means she starts turning late, while a 900 m circle means she comes around inside most of her cohort once she does. Decide a beat early and the turn itself will not let you down.

Potato Avoidance

Launching airstrikes at maneuvering targets

The squadron's travel time is long enough that a healthy DD or cruiser with engine boost simply turns out of the cone. Reserve strikes for capping destroyers, island-huggers, and anyone already tying up with a teammate.

Signature Traits

Airstrike alt-armament

The alt-armament fires a bomber line in place of torpedoes. Rewards behind-cover positioning with the cap in range.

top hull: 1 − 0.6004 fire coefficient = 40%. Lowers how often hits set you on fire. It does not reduce the damage a burning fire does per second; fires burn at the full rate on every ship.

Fire duration60 s

Fire damage

One unattended fire: 0.003 of max HP per second (0.3%) × 60 s = 0.18 of the pool; 0.18 × 102,300 HP = 18,414 HP on this ship. 4 fire points can burn at once.

Torp Reduction

1 − 0.15 hull torpedo-damage coefficient / 0.333 unprotected baseline = 55%. 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.

Effective HP

Base 102,300 HP plus everything Repair Party can restore: 0.005 of max HP per second (0.5%) × 28 s × 102,300 HP = 14,322 HP per charge, × 3 charges = 42,966 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 × 8,900 = 17,800), 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.

8,900

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 × 8,000 = 16,000), 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.

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 × 3,400 = 6,800), 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.

3,400

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 × 10,300 = 20,600), 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.

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.

2x ±150°

Guns to bear

Counted from each mount's firing arc: no mount leaves a blind wedge, so every gun bears straight ahead. 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.

AA explosions

Each ~2 s salvo fires 3 AA explosions in quick succession, each leaving 3 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between salvos - up to 10 clouds per salvo × 230 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.

3 per salvo, 3 clouds each + 1 outer cloud

Cloud damage

Damage a plane takes for flying into one flak cloud, before any reductions.

230

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.

75%

Salvo interval

A new flak salvo (the AA explosions above) fires roughly every 2 s.

Fired by

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 3.5 km or past 5 km - once planes get inside the band, new salvos stop. AA range bonuses push the outer edge out; the 3.5 km inner edge does not move.

Shell Grouping (σ)1

Total secondary fires/min (per side)

Sum of each gun family's fires/min (per side): 3.8 + 4.8 + 1.5 = 10.1. 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.

10.1

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: 6×2 127 mm (6/side) × 60/7.571 s (7.5 s = 53 ticks) × 2100 = 99,849 + 6×2 127 mm (6/side) × 60/6 s × 2100 = 126,000 + 2×3 155 mm (3/side) × 60/12 s × 2600 = 39,000. Assumes every shell hits (real hit rate is lower; the Brawl matchup tool on the Compare page folds in dispersion + target armor).

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, using the ship's own reverse-power ratio. The full curve is on the acceleration chart. Full reverse stops about a quarter faster than a plain Stop order from top speed.

Main battery formulas

vs standard BB18% tighter H · 9% taller V

H = horizontal, V = vertical spread. This ship's curve against the standard battleship curve, both evaluated at this ship's max range (17.7 km) with the same model as Max Horiz/Vert Disp: horizontal 194 / 237 m − 1 = -18%, vertical 155 / 142 m − 1 = +9%. Shell grouping (σ) is separate: it sets how shells bunch toward the centre of this ellipse.

Shell scatter width @ 5 km115 m

(166.7 × (9 − 2.8) / 1000 + 2.8) × 30 = 115 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 km146 m

(333.3 × (9 − 2.8) / 1000 + 2.8) × 30 = 146 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 width @ 15 km177 m

(500 × (9 − 2.8) / 1000 + 2.8) × 30 = 177 m. Horizontal scatter at a fixed 15 km, from the same dispersion model - the long-range anchor. Only shown when the ship's guns reach 15 km.

Shell scatter height @ 5 km49 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,  $radiusOnDelim = 0.6$  at  $delim \cdot R_{m a x} = 0.5 \cdot 17698 = 8849$  m, and  $radiusOnMax = 0.8$  at 17698 m. Below the kink:  $k = 0.2 + (0.6 - 0.2) \cdot \frac{5000}{8849} = 0.426$ , so  $σ_{V} = σ_{H} \cdot k = 115 \cdot 0.426 = 49 m$ .

Shell scatter height @ 10 km91.4 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,  $radiusOnDelim = 0.6$  at  $delim \cdot R_{m a x} = 0.5 \cdot 17698 = 8849$  m, and  $radiusOnMax = 0.8$  at 17698 m. Above the kink:  $k = 0.6 + (0.8 - 0.6) \cdot \frac{10000 - 8849}{17698 - 8849} = 0.626$ , so  $σ_{V} = σ_{H} \cdot k = 146 \cdot 0.626 = 91.4 m$ .

Shell scatter height @ 15 km130.8 m

How tall the scatter ellipse is at a fixed 15 km, from the same model. Only shown when the ship's guns reach 15 km. 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,  $radiusOnDelim = 0.6$  at  $delim \cdot R_{m a x} = 0.5 \cdot 17698 = 8849$  m, and  $radiusOnMax = 0.8$  at 17698 m. Above the kink:  $k = 0.6 + (0.8 - 0.6) \cdot \frac{15000 - 8849}{17698 - 8849} = 0.739$ , so  $σ_{V} = σ_{H} \cdot k = 177 \cdot 0.739 = 130.8 m$ .

AP pen 5 km768 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2574 \cdot 1460^{0.69} \cdot {0.46}^{- 1.07} \cdot {704.7}^{1.38} = 768 mm$ , where 704.7 m/s is the shell's speed when it arrives at 5 km (from 780 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 km671 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2574 \cdot 1460^{0.69} \cdot {0.46}^{- 1.07} \cdot 639^{1.38} = 671 mm$ , where 639 m/s is the shell's speed when it arrives at 10 km (from 780 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 15 km592 mm

AP penetration at a fixed 15 km, from the same ballistic curve as AP Pen Close/Far: the shell's impact velocity at that range fed through the AP formula  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 2574 \cdot 1460^{0.69} \cdot {0.46}^{- 1.07} \cdot {583.9}^{1.38} = 592 mm$ , where 583.9 m/s is the shell's speed when it arrives at 15 km (from 780 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 km5.15 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.292 \cdot {0.46}^{2}}{8 \cdot 1460} = 1.66 \times 10^{- 5}$ . That runs from a 780 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.543 \cdot {0.46}^{2}}{8 \cdot 1360} = 3.32 \times 10^{- 5}$ . That runs from a 805 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.

Model inputs

Krupp (AP)2,574

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 mass1,460 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 coefficient0.292

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

AP muzzle velocity780 m/s

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

HE muzzle velocity805 m/s

Starting speed of the HE shell; sets its flight time and lead.

idealRadius9

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

minRadius2.8

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.

Vertical scatter as a share of horizontal at zero range.

radiusOnDelim0.6

Vertical scatter as a share of horizontal at the delim point.

AA defense

AA DPS at max range106

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors 14x2 -> 192 DPS @ 3.5 km; 13mm76 Type93 double 2x2 -> 6 DPS @ 1.2 km; 25mm Type96 Triple 1945 closed 8x3 -> 45 DPS @ 3.1 km; 25mm Type96 Triple closed 12x3 -> 68 DPS @ 3.1 km; 25mm Type96 light 16x3 -> 89 DPS @ 3.1 km; 25mm Type96 single 14x1 -> 42 DPS @ 3.1 km; 127mm40 Type89 Mod A 6x2 -> 53 DPS @ 5 km; 127mm40 Type 89 6x2 -> 53 DPS @ 5 km.

AA DPS layered by range106 DPS @ 5 km, 298 DPS @ 3.5 km, 542 DPS @ 3.1 km, 548 DPS @ 1.2 km

@ 5 km: 53 + 53 = 106; @ 3.5 km: 192 + 53 + 53 = 298; @ 3.1 km: 192 + 45 + 68 + 89 + 42 + 53 + 53 = 542; @ 1.2 km: 192 + 6 + 45 + 68 + 89 + 42 + 53 + 53 = 548. 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-blank548

192 + 6 + 45 + 68 + 89 + 42 + 53 + 53 = 548 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (1.2 km).

AA threat index1966

192 × 3.5 + 6 × 1.2 + 45 × 3.1 + 68 × 3.1 + 89 × 3.1 + 42 × 3.1 + 53 × 5 + 53 × 5 = 1966. 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.

Secondary battery firepower

Max HE alpha2600

max(2100 (127 mm), 2100 (127 mm), 2600 (155 mm)) = 2600. Maximum HE damage per shell across secondary HE families. Best on this ship: 2600 from the 155 mm family.

Max HE fire chance10%

max(8% (127 mm), 8% (127 mm), 10% (155 mm)) = 10%. Maximum per-shell fire chance across secondary HE families (before target fire resistance is applied). Best on this ship: 10% from the 155 mm family.

Max HE pen26 mm

max(21 mm (127 mm), 21 mm (127 mm), 26 mm (155 mm)) = 26 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: 26 mm from the 155 mm family.

Background

A large hybrid battleship representing a hypothetical option to convert one of the preliminary Yamato-class battleship designs into an aircraft-carrying ship. Such a rebuild could have followed the conversion of the Ise-class battleships into hybrid ships during the final stages of the Pacific War.

Armor Beta

Hull HP 102,300, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are estimates.

Citadel	410 mm primary (range 16–410 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 primary (range 19–50 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.
