Hit Points33,500
Displacement8,470 t
Hull dimensions ƒ
Length x beam at the waterline, with the hull's draft where the client carries one. Ships whose client entry holds only the 260 x 20 m placeholder use a curated real-world figure instead, and any ship we have no trustworthy size for omits this row rather than print the placeholder. Length matters when dodging torpedoes; beam and draft shape how hard the ship is to hit.
Armor range6–89 mm
Plate armor thicknesses6, 13, 16, 25, 32, 40, 51, 65, 89 mm
Armor material/layer entries81
Fire resistance ƒ
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.
Fire duration30 s
Fire damage ƒ
Each fire ticks 0.3% of max HP per second for the full 30 s, so one unattended fire burns 9% of the pool (3,015 HP on this ship). 4 fire points can burn at once. Verified against measured burn ticks in replay data.
Flood duration40 s
Flood damage ƒ
A flood ticks 0.25% of max HP per second for the 40 s duration, so one unattended flood costs 10% of the pool (3,350 HP on this ship). Verified against measured flood ticks in replay data.
Torp Reduction ƒ
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 ƒ
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 ƒ
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 ƒ
Base 33,500 HP plus everything Repair Party can restore: 0.6%/s x 28 s = 5,628 HP per charge, x2 charges = 11,256 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. Repair Party is one choice in its slot on this ship, so this applies only if you take it.

Turret traverse arcs ƒ
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.
Guns to bear ƒ
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.

Shells/min ƒ
Zero upgrades: 14 broadside guns x 60 / 6 s base reload = 140. All upgrades (Main Battery Mod. 3 = -10% reload): 14 broadside guns x 60 / 5.4 s all-upgrades reload = 155.6.
SAP shells
SAP Damage2,300
SAP Velocity792 m/s
SAP Pen (mm)36
SAP Fragment Radius ƒ
SAP shell fragment splash radius; the area over which a SAP hit scatters fragment damage. Scales with shell mass (90mm ~ 5, 203mm CA ~ 20-30, 320mm = 175, 406mm = 250, 457mm = 400, max) and is tuned per ship, so two ships with the same SAP caliber can differ (135mm ranges 5-24). Larger value = wider fragment spread per hit.

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity: . Matches the in-game spec card.
AP Pen Far ƒ
Same formula at the ship's max firing range (15.3 km), where the shell has slowed to 351.7 m/s: .
AP full-salvo alpha ƒ
2,100 AP damage x 14 broadside guns = 29,400.
AP DPM ƒ
Zero upgrades: 29,400 AP full-salvo alpha x 60 / 6 s base reload = 294,000. All upgrades (Main Battery Mod. 3 = -10% reload): 29,400 AP full-salvo alpha x 60 / 5.4 s all-upgrades reload = 326,667.
AP AOE Radius ƒ
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.

Maximum simulated damage ƒ
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: .
Maximum damage (ammunition) ƒ
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 ƒ
How long a target has to dodge after your torpedo is spotted at its detectability range (lower means less warning): . 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.
Flooding chance ƒ
Read straight from the game's own data: this torpedo carries a flooding-chance value of 2.79 per hit, shown as . 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.

Bursts ƒ
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 × 230 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 ƒ
Damage a plane takes for flying into one flak cloud, before any reductions.
Cloud spawn chance ƒ
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 ƒ
A flak wave spawns roughly every 2 s - timed frame-by-frame from gameplay footage and consistent across ships.
Fired by ƒ
Flak keeps firing while at least one main battery mount is operational - even losing every other AA mount does not stop it.
Flak zone ƒ
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.

Reverse speed ƒ
top speed / 4 + 4.9 = 32.5 / 4 + 4.9 = 13 kt. The community reverse-speed model from the WoWs ShipBuilder project, the same source as the acceleration model on this card. Base value; speed modifiers scale it. Not shown on the in-game card.
Crash stop ƒ
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.
Engine boost threshold (reverse) ƒ
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).
Acceleration 0-90% ƒ
Time to reach 90% of top speed (29.2 kt of 32.5 kt), from our in-house acceleration model.
Acceleration 0-99% ƒ
Time to reach 99% of top speed (32.2 kt of 32.5 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 ƒ
How many degrees the turret can swing for each degree the hull turns. Turn rate , so . Below 5 the turrets drag in a turning fight; 25+ keeps up with any rudder.
Detectability by sea11.89 km
Detectability by air7.13 km

Detect when firing (sea) ƒ
Equal to the ship's main battery range (never below base detectability): firing makes you visible to everyone you can reach. Matches the in-game 'Detect Firing Sea' value on all 8 unmodified captures, and range-modified captures track the modified range.
Detect when firing (air) ƒ
Air detectability plus the gun-firing bloom (2.54 km, which tracks main-battery caliber x 0.020). Matches the in-game 'Detect Firing Air' value on every captured ship.
Detect when on fire (sea) ƒ
Base sea detectability + 2.0 km while burning; matches the in-game 'Detect Fire Sea' value on every captured ship.
