Overview

San Martin is a Legendary Pan-American cruiser: a 152mm HE and AP battery, ten torpedo tubes, and no secondaries at all. High-Frequency Sonar lets her contest caps and island lines without taking the spotting cycle, and her second slot chooses between Smoke Generator and Repair Party, so she can be built to break contact or to absorb it.

Positioning

Work the cap edge with sonar up, close enough that the torpedo tubes are a real threat rather than a decoration.

Potato Avoidance

Treating her as a gunboat that happens to carry torpedoes

Sonar plus ten tubes is the kit; the guns are what she does between those.

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 49,800 HP plus everything Repair Party can restore: 1.2%/s x 28 s = 16,733 HP per charge, x2 charges = 33,466 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.

Range10.5 km

Maximum simulated damage

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:

D_{sim} = α \cdot c = 49, 200 \cdot 0.333 = 16, 400

≈ 16,400

Maximum damage (ammunition)

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

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

t_{react} = \frac{1.3 km}{66 kt \times 2.6} = 7.6 s

, equivalently

5000 \times detectability / (13 \times speed)

. Base value; commander torpedo-concealment skills lower it further. Community torpedo-reaction calculator by u/LorenDovah and u/The_ColorOutofSpace.

7.6 s

Flooding chance

Read straight from the game's own data: this torpedo carries a flooding-chance value of 2.96 per hit, shown as

2.96 \times 100 = 296 %

. 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

Each ~2 s wave fires 3 quick salvos of 4 clouds ahead of the attacking squadron, plus 1 stray cloud farther out that appear off-beat between waves - up to 13 clouds per wave × 290 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.

3 salvos × 4 clouds + 1 outer

Cloud damage

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

290

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.

90%

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 main battery mount is operational - even losing every other 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 bursts can land short of 2.5 km or past 6 km - once planes get inside the band, new waves stop.

Traverse-to-turn ratio

How many degrees the turret can swing for each degree the hull turns. Turn rate

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{25}{1.27} = 19.7 \times

Shell Grouping (σ)2.05

Max Horiz Disp131.3 m

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model:  $σ_{H} = (\frac{R}{30} \cdot \frac{idealRadius - minRadius}{idealDistance} + minRadius) \cdot 30$   $= (\frac{15510}{30} \cdot \frac{8 - 0.5}{1000} + 0.5) \cdot 30 = 131.3 m$

Shell scatter width @ 5 km52.5 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 km90 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 km127.5 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 Disp78.8 m

Vertical dispersion ellipse height at max range: $σ_{V} = σ_{H} \cdot radiusOnMax$ $= 131.3 \cdot 0.6 = 78.8 m$

Shell scatter height @ 10 km47.6 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  $delim \cdot R_{m a x} = 0.5 \cdot 15510 = 7755$  m, and  $radiusOnMax = 0.6$  at 15510 m. Above the kink:  $k = 0.5 + (0.6 - 0.5) \cdot \frac{10000 - 7755}{15510 - 7755} = 0.5289$ , so  $σ_{V} = σ_{H} \cdot k = 90 \cdot 0.5289 = 47.6 m$ .

Med Horiz Disp38.4 m

50%-hit horizontal radius: $σ_{H, 50} = σ_{H} \cdot \frac{0.6}{σ}$ $= 131.3 \cdot \frac{0.6}{2.05} = 38.4 m$

Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity:  $P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}$   $= 10^{- 7} \cdot 2692 \cdot 59^{0.69} \cdot {0.152}^{- 1.07} \cdot 812^{1.38} = 348.8 mm$ . Matches the in-game spec card.

AP Pen Far122 mm

Same formula at the ship's max firing range (19.4 km), where the shell has slowed to 379.3 m/s:  $P = 10^{- 7} \cdot 2692 \cdot 59^{0.69} \cdot {0.152}^{- 1.07} \cdot {379.3}^{1.38} = 122 mm$ .

AP pen 5 km246 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 km177 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 km133 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 km5.68 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:  $k = \frac{π C_{d} d^{2}}{8 m} = \frac{π \cdot 0.25 \cdot {0.152}^{2}}{8 \cdot 59} = 3.84 \times 10^{- 5}$ . That runs from a 812 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.

floor(152 mm caliber / 14.3) = 10 mm (AP auto-penetrates plating this thick or less).

AP AOE Radius20

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.

Broadside guns used for alpha10

All 10 barrels bear on the broadside.

Turret turn time7.2 s

180 degrees / 25 deg/s traverse speed = 7.2 s.

HE full-salvo alpha22,000

2,200 HE damage x 10 broadside guns = 22,000.

AP full-salvo alpha34,000

3,400 AP damage x 10 broadside guns = 34,000.

HE DPMInitial: 264,000 → 293,333

Zero upgrades: 22,000 HE full-salvo alpha x 60 / 5 s base reload = 264,000. All upgrades (Main Battery Mod. 3 = -10% reload): 22,000 HE full-salvo alpha x 60 / 4.5 s all-upgrades reload = 293,333.

AP DPMInitial: 408,000 → 453,333

Zero upgrades: 34,000 AP full-salvo alpha x 60 / 5 s base reload = 408,000. All upgrades (Main Battery Mod. 3 = -10% reload): 34,000 AP full-salvo alpha x 60 / 4.5 s all-upgrades reload = 453,333.

Shells/minInitial: 120 → 133.3

Zero upgrades: 10 broadside guns x 60 / 5 s base reload = 120. All upgrades (Main Battery Mod. 3 = -10% reload): 10 broadside guns x 60 / 4.5 s all-upgrades reload = 133.3.

Fires/minInitial: 9 → 10

Zero upgrades: 120 shells/min x 7.5% fire chance = 9. All upgrades (Main Battery Mod. 3 = -10% reload): 133.3 shells/min x 7.5% fire chance = 10.

Torpedoes

Torpedo speed66 kt

Travel time to max range61.2 s

range / (speed kt x 2.6 community game-speed factor).

Tube count10

2 launchers x 5 tubes.

Per-side salvo5 torpedoes

tube count / 2 (symmetric port/starboard launcher layout; common on cruisers and battleships with deck torpedoes).

Full-salvo damage164,000

All tubes hitting one target: tubes x per-torpedo simulated damage = 10 x 16,400 = 164,000.

Per-side salvo damage82,000

One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 5 x 16,400 = 82,000.

AA defense

AA DPS at max range95

Only families that reach 6 km contribute at the outer edge of the AA bubble. In-game families: 3in50 Twin Mark 33 9x2 -> 278 DPS @ 4 km; 3in50 MK34 Radar 2x1 -> 62 DPS @ 4 km; 20mm Oerlikon MK20 Twin 10x2 -> 104 DPS @ 2 km; Far AA (?) -> 95 DPS @ 6 km.

Maximum AA range6 km

Longest-reaching family on the in-game AA card. Base AirDefense aura max range is 4 km; dual-purpose mount auras extend it.

AA DPS layered by range95 DPS @ 6 km, 435 DPS @ 4 km, 539 DPS @ 2 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-blank539

Sum of every family's average DPS, achievable only inside the closest-range family (2 km).

AA threat index2138

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 range2 km

Armor Beta

Hull HP 49,800, 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 & stern25 mm

Overmatched by 52+ guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Belt / citadel127 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	25 mm primary (range 25–40 mm)	2,000 (4% of HP)	Overmatched by 380mm+ (Alsace, Bourgogne)Angle bounces 356mm25 mm: HE pens from 150mm+	Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.
Hull (midship)	25 mm primary (range 25–127 mm)	37,400 (75% of HP)	Overmatched by 380mm+ (Alsace, Bourgogne)Angle bounces 356mm25 mm: HE pens from 150mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	25 mm primary (range 6–89 mm)	3,200 (6% of HP)	Overmatched by 380mm+ (Alsace, Bourgogne)Angle bounces 356mm25 mm: HE pens from 150mm+	Mirror of bow. Same fast saturation.
Citadel	127 mm primary (range 13–127 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	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	24,900 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	14,900 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.
