Overview

Jinan is a Legendary Pan-Asian light cruiser whose Smoke Generator lets her trade DPM from cover instead of from open water. The kit rewards static, sustained fire rather than rotation play. Standout traits: surface detection in Legendary CAs (11.9 km, 2nd of 21) and best torpedo speed in Legendary CAs (69 kt, 1st of 13). The trade is short gun range in Legendary CAs (15.1 km, 21st of 21).

Positioning

Anchor near your smoke cycle on a contested cap and trade DPM from inside the cloud. The kit rewards a static firing position; rotating mid-smoke wastes the consumable for the next contest. Your guns lose penetration at range, so aim AP at broadsides you can still citadel and put HE into superstructures and upper-hull sections, rather than the bow-in or belt armor your shells bounce and shatter on. Shooting from the cloud gives you away at 6.2 km, and a destroyer here is spotted at about 7.1 km, so you see it coming with roughly 0.94 km to spare. Vision is mutual: past the 2 km guaranteed ring you cannot see out either, and nothing in her kit sees through it, so pop the smoke where someone is already lighting the enemy or you will sit in it with nothing to shoot. Enemy sonar (about 4.9 km) and radar (about 9.9 km) read straight in regardless. She is genuinely evasive in both phases of a turn, answering the helm in 7.7 s and carving a 670 m circle, so you can break a salvo and still be where you meant to go.

Potato Avoidance

Burning Torpedo Reload Booster on a hopeful salvo These torpedoes ignore the Destroyer class

With only 2 charges it is a finisher rather than an opener: spend it on a target that cannot turn away, a broadside battleship or a cruiser already committed to its own attack, where the extra torpedo salvo lands as damage instead of splashes. A booster pressed on a maybe is one you will not have when the certainty shows up. Aim torpedo drops ONLY at battleships, carriers, and most cruisers; every torp fired at a DD is wasted output.

Signature Traits

Deep-water torpedoes

Torps IGNORE the Destroyer class (deep-water mechanic); they pass under DDs and cannot hit them. Aim ONLY at battleships, carriers, and most cruisers; every torp fired at a DD is wasted, unique in Legendary CAs.

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.

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 39,900 HP plus everything Repair Party can restore: 0.005 of max HP per second (0.5%) × 28 s × 39,900 HP = 5,586 HP per charge, × 2 charges = 11,172 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. Repair Party is one choice in its slot on this ship, so this applies only if you take it.

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 × 1,400 = 2,800), 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.

1,400

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 × 5,400 = 10,800), 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.

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 × 2,600 = 5,200), 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 ×. 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.

2,600

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 × 2,600 = 5,200), 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.

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).

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.

Guns to bear

180° − 155° (the most restricted aft-facing mount's arc) = 25° off bow; 180° − 149° (the most restricted forward-facing mount's arc) = 31° 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.

Reload time120 s

Projectile speed69.0 kt

Range13.5 km

Maximum simulated damage

Most targets only intersect one hull section, so a hit transfers about 1/3 of the warhead alpha (2/3 when the warhead blast >= 5000 and the burst reaches a second section). For this ship:

D_{sim} = α \cdot c = 52, 100 \cdot 0.333 = 17, 367

. In battle, a hit on the torpedo belt deals the per-hit figure × (1 − the target's torpedo protection %), a bow or stern hit deals it in full, and a torpedo never counts as a citadel hit.

≈ 17,367

Maximum damage (ammunition)

52,100 warhead alpha / 3 + 1,200 blast = 18,567. Warhead alpha / 3 plus the blast addend: the per-torpedo damage figure. The 'Maximum simulated damage' row above applies target geometry to the same warhead.

18,567

Torpedo module damage

Per-torpedo module/blast damage parameter. Most torpedoes carry 500 to 2,000; ships announced by WG as dealing increased module damage carry 9,000 to 12,000, so their hits knock out engines, rudders, and turrets far more often. Comparative figure.

1,200

Torpedo detectability0.8 km

Reaction time

How long a target has to dodge after your torpedo is spotted at its detectability range (lower means less warning):

t_{react} = \frac{0.8 km}{69 kt \times 2.6855} = 4.3 s

. 2.6855 converts knots to m/s on the game clock. Base value; commander torpedo-concealment skills lower it further.

4.3 s

Flooding chance

This torpedo carries a flooding-chance value of 3.68 per hit, shown as

3.68 \times 100 = 368 %

. 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.

AA explosions

Each ~2 s salvo fires 3 AA explosions in quick succession, each leaving 4 clouds ahead of the attacking squadron, plus 2 stray clouds farther out that appear off-beat between salvos - up to 14 clouds per salvo × 280 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, 4 clouds each + 2 outer clouds

Cloud damage

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

280

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.

90%

Salvo interval

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

every ~2 s

Fired by

Flak keeps firing while at least one main battery mount is operational - even losing every dedicated AA mount does not stop it.

Main 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 2.5 km or past 5.2 km - once planes get inside the band, new salvos stop. AA range bonuses push the outer edge out; the 2.5 km inner edge does not move.

Main battery formulas

vs standard cruiserStandard

The standard cruiser dispersion curve.

Shell scatter width @ 5 km67.5 m

(166.7 × (8 − 1.1) / 1000 + 1.1) × 30 = 67.5 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 km102 m

(333.3 × (8 − 1.1) / 1000 + 1.1) × 30 = 102 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 km136.5 m

(500 × (8 − 1.1) / 1000 + 1.1) × 30 = 136.5 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 km26.9 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,  $radiusOnDelim = 0.5$  at  $delim \cdot R_{m a x} = 0.5 \cdot 15100 = 7550$  m, and  $radiusOnMax = 0.6$  at 15100 m. Below the kink:  $k = 0.2 + (0.5 - 0.2) \cdot \frac{5000}{7550} = 0.3987$ , so  $σ_{V} = σ_{H} \cdot k = 67.5 \cdot 0.3987 = 26.9 m$ .

Shell scatter height @ 10 km54.3 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,  $radiusOnDelim = 0.5$  at  $delim \cdot R_{m a x} = 0.5 \cdot 15100 = 7550$  m, and  $radiusOnMax = 0.6$  at 15100 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7550}{15100 - 7550} = 0.5325$ , so  $σ_{V} = σ_{H} \cdot k = 102 \cdot 0.5325 = 54.3 m$ .

Shell scatter height @ 15 km81.7 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,  $radiusOnDelim = 0.5$  at  $delim \cdot R_{m a x} = 0.5 \cdot 15100 = 7550$  m, and  $radiusOnMax = 0.6$  at 15100 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{15000 - 7550}{15100 - 7550} = 0.5987$ , so  $σ_{V} = σ_{H} \cdot k = 136.5 \cdot 0.5987 = 81.7 m$ .

AP pen 5 km98 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 1720 \cdot {31.75}^{0.69} \cdot {0.127}^{- 1.07} \cdot {529.9}^{1.38} = 98 mm$ , where 529.9 m/s is the shell's speed when it arrives at 5 km (from 808 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 km57 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 1720 \cdot {31.75}^{0.69} \cdot {0.127}^{- 1.07} \cdot {360.1}^{1.38} = 57 mm$ , where 360.1 m/s is the shell's speed when it arrives at 10 km (from 808 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 km41 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  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v^{1.38}$   $= 10^{- 7} \cdot 1720 \cdot {31.75}^{0.69} \cdot {0.127}^{- 1.07} \cdot {284.8}^{1.38} = 41 mm$ , where 284.8 m/s is the shell's speed when it arrives at 15 km (from 808 m/s at the muzzle). Fixed anchors make ships directly comparable at the same fighting distance; the Charts card plots the full curve.

HE flight time @ 10 km7.02 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.347 \cdot {0.127}^{2}}{8 \cdot 31.75} = 6.92 \times 10^{- 5}$ . That runs from a 808 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.

AP flight time @ 10 km7.02 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.347 \cdot {0.127}^{2}}{8 \cdot 31.75} = 6.92 \times 10^{- 5}$ . That runs from a 808 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.

Guns per full salvo (alpha, DPM)10

5 mounts × 2 barrels = 10; all 10 bear on the broadside.

Model inputs

Krupp (AP)1,720

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 mass31.75 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 coefficient0.347

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

AP muzzle velocity808 m/s

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

HE muzzle velocity808 m/s

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

idealRadius8

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

minRadius1.1

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.

radiusOnZero0.2

Vertical scatter as a share of horizontal at zero range.

radiusOnDelim0.5

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

radiusOnMax0.6

Vertical scatter as a share of horizontal at maximum range.

delim0.5

Where the vertical-scatter curve bends, as a share of maximum range.

Torpedoes

Estimated torpedo reaction time4.3 s

800 m / (69.0 kt × 2.6855) = 4.3 s. detectability / (speed kt x 2.6855 m/s per knot on the game clock).

Torpedo speed69.0 kt

Travel time to max range72.9 s

13500 m / (69.0 kt × 2.6855) = 72.9 s. range / (speed kt x 2.6855 m/s per knot on the game clock).

Tube count20

4 launchers × 5 tubes.

Per-side salvo10 torpedoes

20 wing tubes / 2 = 10: the launchers sit one per beam, so only half of them reach any one side. Each launcher reloads on its own, so she can fire one beam, turn, and fire the other without waiting.

Full-salvo damage347,340

All tubes hitting one target: tubes x per-torpedo simulated damage = 20 x 17,367 = 347,340. Each hit on the target's torpedo belt is reduced by its torpedo protection %.

AA defense

AA DPS at max range180

Only families that reach 5.2 km contribute at the outer edge of the AA bubble. In-game families: 3in70 Mark37 7x2 -> 365 DPS @ 4 km; Far AA (?) -> 180 DPS @ 5.2 km.

AA DPS layered by range180 DPS @ 5.2 km, 545 DPS @ 4 km

@ 5.2 km: 180 from one family; @ 4 km: 365 + 180 = 545. 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-blank545

365 + 180 = 545 DPS: the sum of every family's average DPS, achievable only inside the closest-range family (4 km).

AA threat index2396

365 × 4 + 180 × 5.2 = 2396. 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.

Background

A variant of the light cruiser developed in the United States at the end of World War II (CL-154), with reinforced torpedo armament.

Armor Beta

Hull HP 39,900, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds.

Bow & stern16 mm

Overmatched by 83+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel225 mm

AP can citadel a flat broadside even at range. Stay angled and avoid showing the full side.

Farming13 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 40%, fires burn 30s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	16 mm primary (range 16–40 mm)	1,400 (4% of HP)	Overmatched by 283mm+ AP (Gouden Leeuw)Angle bounces 203mm16 mm: HE pens from 127mm+	Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.
Hull (midship)	16 mm primary (range 16–225 mm)	29,900 (75% of HP)	Overmatched by 283mm+ AP (Gouden Leeuw)Angle bounces 203mm16 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	16 mm primary (range 16–75 mm)	2,600 (7% of HP)	Overmatched by 283mm+ AP (Gouden Leeuw)Angle bounces 203mm16 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	225 mm primary (range 6–95 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	13 mm primary (range 13–32 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).
Turret (module, per magazine)	separate HP pool, does not drain ship HP	17,400 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.
AA mount (76 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	12,000 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.
