Hit Points12,600
Displacement1,860 t
Hull dimensions ƒ
Length x beam at the waterline, plus draft. Length matters when dodging torpedoes; beam and draft shape how hard the ship is to hit.
Armor range6–10 mm
Plate armor thicknesses6, 10 mm
Armor material/layer entries22
Fire resistance ƒ
top hull: 1 − 1 fire coefficient = 0%. 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 duration30 s
Fire damage ƒ
One unattended fire: 0.003 of max HP per second (0.3%) × 30 s = 0.09 of the pool; 0.09 × 12,600 HP = 1,134 HP on this ship. 4 fire points can burn at once.
Flood duration40 s
Flood damage ƒ
One unattended flood: 0.0025 of max HP per second (0.25%) × 40 s = 0.1 of the pool; 0.1 × 12,600 HP = 1,260 HP on this ship.
Torp Reduction ƒ
1 − 0.31 hull torpedo-damage coefficient / 0.333 unprotected baseline = 7%. Reduces torpedo hit damage. It does not affect flooding: floods start as often and tick at the full rate.
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.
Repairable: penetration50%
Repairable: steering gear50%
Bow section HP ƒ
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.
Casemate section HP ƒ
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).
Hull section HP ƒ
Damage saturation pool for the hull: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 4,700 = 9,400), 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.
Superstructure section HP ƒ
Damage saturation pool for the superstructure: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 300 = 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 ×. 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.
Stern section HP ƒ
Damage saturation pool for the stern: penetrations here deal their normal share until twice this much penetration damage has landed on the section (2 × 600 = 1,200), 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.

Guns to bear ƒ
180° − 153° (the most restricted aft-facing mount's arc) = 27° off bow; 180° − 153° (the most restricted forward-facing mount's arc) = 27° 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.

Dispersion type ƒ
In practice: 10% tighter (better) horizontal dispersion and 10% less vertical spread at max range (11.1 km) than a standard cruiser: about 99 m wide × 59 m tall, against 110 m × 66 m. Also on this curve (225): AL Avrora, AL Yukikaze, AL Z24, Acasta, Achilles, Adriatico, Aigle, Akatsuki, Akizuki, Albany, Allen M. Sumner, Attilio Regolo and 213 more.

HE penetration ƒ
17 mm ≈ 102 mm caliber / 6 (standard HE penetration ratio).

800 HE damage x 4 broadside guns = 3,200.

3,200 HE full-salvo alpha x 60 / 3.571 s (3.5 s = 25 ticks) base reload = 53,760.

Maximum AA range ƒ
Longest-reaching family on the in-game AA card. Base AirDefense aura max range is 2 km; dual-purpose mount auras extend it.
20 mm Oerlikon Mk44×1 20mm
Guns20 mm Oerlikon Mk4
Continuous DPS ƒ
Effective DPS: 15 raw aura damage × 3.5 × 0.85 hit probability = 45 - the same in-game units as the Close-range AA DPS headline.

Maximum speed20.3 kt
Turning circle radius320 m
Rudder shift time3 s
Engine power-boost threshold7.0 kt
Engine spool-up time15.3 s
Reverse spool-up time7.7 s
Reverse speed ƒ
top speed / 4 + 4.9 = 20.3 / 4 + 4.9 = 10.0 kt. Base value; speed modifiers scale it.
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, 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.
Engine boost threshold (reverse) ƒ
Speed below which the engine's built-in power boost applies in reverse.
Acceleration 0-90% ƒ
Time to reach 90% of top speed (18.3 kt of 20.3 kt).
Acceleration 0-99% ƒ
Time to reach 99% of top speed (20.1 kt of 20.3 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.
Guns in a full turn ƒ
With the rudder hard over the hull turns 7.8°/s, so a target drifts across the bow at that rate. Turret traverse minus hull turn: 8 − 7.8 = +0.2°/s, so the guns hold the target through the turn. Main Battery Mod. 2 (+20% traverse) and Mod. 3 (−15%) move this line.
Detectability by sea ƒ
Base value, no camouflage. With a Grade IV permanent camo (or any disposable camo): 8.62 km x 0.955 = 8.23 km. Camouflage does not change detectability by air.
With Grade IV camouflage (sea) ƒ
Detectability by sea 8.62 km x 0.955 (Grade IV permanent camo or any disposable camo) = 8.23 km.
Detectability by air4.66 km
Smoke firing penalty2.89 km
Detect when firing (sea) ƒ
Larger of 11.14 km range and 2.89 km smoke firing penalty = 11.14 km. When you fire, you can be seen out to your main battery range. Skills that shorten your range don't shorten this below your smoke firing penalty.
Detect when firing (air) ƒ
Air detectability 4.66 km + gun-firing bloom 2.4 km = 7.06 km. The bloom tracks main-battery caliber x 0.020.
Detect when on fire (sea) ƒ
Sea detectability 8.62 km + 2.0 km while burning = 10.62 km.
Detect when on fire (air) ƒ
Air detectability 4.66 km + 3.0 km while burning = 7.66 km.
