Overview

Suwo is the Tier VII 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. AA (694 AA DPS at 5 km) ranks 4 of 49 in T7 BBs: heavy enough to make a careless strike expensive, though not the umbrella that shuts a carrier out of her grid. Standout traits: best heavy citadel belt in T7 BBs (410 mm) and best high-arc HE shells in T7 BBs (20.7°).

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. Both phases of a turn are slow (22.1 s on the rudder, a 890 m circle), so course changes are a plan rather than a reaction: set the angle before you are shot at.

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.

Builds

Jisaburō Ozawa

Airstrike specialist

InspirationsCommander Worf · Jonathan Hawke

Ozawa's Hidden Hand adds +1 airstrike squadron AND reduces cooldown by 50%, so he roughly doubles strike output across a match. Worf's Sky Attack trait raises damage of all dropped projectiles; Hawke's Big Game Hunter focuses the squadron damage specifically on BB / CA / CV targets. Main battery still anchors the fight; airstrikes punish island-huggers and capping destroyers.

Jisaburō Ozawa

Big Game Hunter

InspirationsJonathan Hawke · Commander Worf

Same Ozawa spine (+1 squadron, -50% cooldown). Hawke's Big Game Hunter trait pushes airstrike damage hardest against BB / CA / CV; Worf's Sky Attack adds universal damage to every dropped projectile so the kit still pulls weight when you can only line up a DD. Tighter big-target focus than the universal pairing, with Worf as the safety net.

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.

Initial: 33.3% → 36.6%

Fire duration60 s

Fire damage

Each fire ticks 0.3% of max HP per second for the full 60 s, so one unattended fire burns 18% of the pool (13,086 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 0.5% of max HP per second for the 40 s duration, so one unattended flood costs 20% of the pool (14,540 HP on this ship). Verified against measured flood ticks in replay data.

0.5% 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.

25%

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.

39,500

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.

21,800

Effective HP

Base 72,700 HP plus everything Repair Party can restore: 0.5%/s x 28 s = 10,178 HP per charge, x3 charges = 30,534 HP. Ceiling, not a prediction: a charge only restores damage actually taken, and only the regeneratable share of it. Across 1,826 players in our replay corpus the median ship realized about half of this, mostly because half the charges go unspent — when Repair Party IS pressed it returns ~97% of the per-charge figure above.

Bursts

Each ~2 s wave fires 2 quick salvos of 4 clouds ahead of the attacking squadron, plus 2 stray clouds farther out that appear off-beat between waves - up to 10 clouds per wave × 210 damage each. Planes that fly into a cloud take its damage; clouds dissipate before the next wave lands. Defensive AA Fire, where fitted, multiplies the salvo repeats within each wave.

Cloud damage

Cloud spawn chance

Each cloud in the pattern rolls this chance to spawn, so waves 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.

Wave rate

A flak wave spawns roughly every 2 s - timed frame-by-frame from gameplay footage and consistent across ships.

Fired by

Flak keeps firing while at least one secondary battery mount is operational - even losing every other 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 bursts can land short of 2.5 km or past 5 km - once planes get inside the band, new waves stop. AA range bonuses push the outer edge out; the 2.5 km inner edge does not move.

35 s

Acceleration 0-99%

Time to reach 99% of top speed (26.9 kt of 27.2 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.

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{27.2 \cdot 0.5144}{890} = 0.90 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{4}{0.90} = 4.4 \times

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{17440.5}{30} \cdot \frac{9 - 2.8}{1000} + 2.8) \cdot 30 = 192.1 m$

Shell scatter width @ 5 km115 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 km146 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

Horizontal scatter at a fixed 15 km, from the same verified dispersion model - the long-range anchor. Only shown when the ship's guns reach 15 km.

Max Vert Disp153.7 m at 17.4 km

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 192.1 \cdot 0.8 = 153.7 m$

Shell scatter height @ 10 km91.9 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  $delim \cdot R_{m a x} = 0.5 \cdot 17440.5 = 8720$  m, and  $radiusOnMax = 0.8$  at 17440.5 m. Above the kink:  $k = 0.6 + (0.8 - 0.6) \cdot \frac{10000 - 8720}{17440.5 - 8720} = 0.6294$ , so  $σ_{V} = σ_{H} \cdot k = 146 \cdot 0.6294 = 91.9 m$ .

Med Horiz Disp54.9 m at 17.4 km

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 192.1 \cdot \frac{0.6}{2.1} = 54.9 m$

Med Vert Disp43.9 m at 17.4 km

50%-hit vertical radius: $σ_{V, 50} = σ_{V} \cdot \frac{0.6}{σ}$ $= 153.7 \cdot \frac{0.6}{2.1} = 43.9 m$

AP Pen Close859.3 mm point-blank

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2711 \cdot 1020^{0.69} \cdot {0.41}^{- 1.07} \cdot 806^{1.38} = 859.3 mm$ . Matches the in-game spec card.

AP Pen Far461.1 mm at 17.4 km

Same formula at the ship's max firing range (17.4 km), where the shell has slowed to 513.4 m/s:  $P = 10^{- 7} \cdot 2711 \cdot 1020^{0.69} \cdot {0.41}^{- 1.07} \cdot {513.4}^{1.38} = 461.1 mm$ .

AP pen 5 km708 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$ . Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

AP pen 10 km587 mm

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.

AP pen 15 km496 mm

AP penetration at a fixed 15 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 km5.63 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.505 \cdot {0.41}^{2}}{8 \cdot 938.5} = 3.55 \times 10^{- 5}$ . 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: 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.

AP flight time @ 10 km5.18 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.355 \cdot {0.41}^{2}}{8 \cdot 1020} = 2.3 \times 10^{- 5}$ . That runs from a 806 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 penetration68 mm

68 mm ≈ 410 mm caliber / 6 (standard HE penetration ratio).

AP overmatch28 mm

floor(410 mm caliber / 14.3) = 28 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius150

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.

All 6 barrels bear on the broadside.

Turret turn time45 s

180 degrees / 4 deg/s traverse speed = 45 s.

Zero upgrades: 6 broadside guns x 60 / 31 s base reload = 11.6. All upgrades (Main Battery Mod. 3 = -10% reload): 6 broadside guns x 60 / 27.9 s all-upgrades reload = 12.9.

Fires/minInitial: 3.48 → 3.87

Zero upgrades: 11.6 shells/min x 30% fire chance = 3.48. All upgrades (Main Battery Mod. 3 = -10% reload): 12.9 shells/min x 30% fire chance = 3.87.

AA defense

AA DPS at max range210

Only families that reach 5 km contribute at the outer edge of the AA bubble. In-game families: 40mm Bofors closed 14x2 -> 189 DPS @ 3.5 km; 25mm Type96 26x3 -> 202 DPS @ 3.1 km; 25mm Type96 single 12x1 -> 93 DPS @ 3.1 km; 100mm65 Type98 12x2 -> 210 DPS @ 5 km.

Maximum AA range5 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 range210 DPS @ 5 km, 399 DPS @ 3.5 km, 694 DPS @ 3.1 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-blank694

Sum of every family's average DPS, achievable only inside the closest-range family (3.1 km).

AA threat index2626

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 range3.1 km

Secondary battery dispersion

Secondary dispersion typeStandard

Max dispersion = range (km) × 57 + 30. Each dispersion type sets its own slope; this is not a percentage applied to a standard baseline.

Max secondary dispersion @ 5 km315 m

5 km × 57 + 30 = 315 m.

Secondary battery firepower

Secondary DPM (per side)447,000

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: 12×2 100 mm (12/side) × 60/3 × 1700 = 408,000 + 2×3 155 mm (3/side) × 60/12 × 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).

Max HE alpha2600

Maximum HE damage per shell across secondary HE families. Best on this ship: 2600 from the 155 mm family.

Max HE fire chance10%

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

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.

Armor Beta

Hull HP 65,500 → 72,700 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.

Bow & stern32 mm

Overmatched by AP from only MusashiARP Musashi. Angled, everything else bounces.

Belt / citadel356 mm

Citadels come from a flat broadside at close range; held past ~30° of angle, AP shatters or bounces.

Farming19 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 37%, fires burn 60s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic

Hull (midship)	32 mm primary (range 22–410 mm)	54,500 (75% of HP)	Overmatched by 460mm+ AP (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	32 mm primary (range 32–356 mm)	2,700 (4% of HP)	Overmatched by 460mm+ AP (Aki, Musashi)Angle bounces 410mm32 mm: HE pens from 203mm+	Mirror of bow. Same fast saturation.
Citadel	356 mm primary (range 38–410 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	19 mm primary (range 19–410 mm)	1,200 (2% 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	39,500 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 (155 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 (40 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	21,800 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.
