Hit Points19,000

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 range10–16 mm
Plate armor thicknesses10, 15, 16 mm
Armor material/layer entries24
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 (1,710 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 (1,900 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.

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.

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.

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 detectability1.4 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 2.46 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.

Reverse speed ƒ
top speed / 4 + 4.9 = 36 / 4 + 4.9 = 13.9 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 (32.4 kt of 36 kt), from our in-house acceleration model.
Acceleration 0-99% ƒ
Time to reach 99% of top speed (35.6 kt of 36 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.

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
