Phra Ruang is a Tier II Pan-Asian torpedo destroyer. The torpedoes travel, so target reaction time is shorter than peer DDs; this is a torpedo-spam kit, not a gun trade kit. AA (56 AA DPS at 2.5 km) is heavy enough to make her the team's air-defense anchor on top of the lead role; CV strikes route around her, not through. Standout traits: best top speed in T2 DDs (36 kt) and top-decile power per turn radius in T2 DDs (64.4 HP).
Sit at the edge of a contested cap from concealment and cycle torpedo waves into lanes the enemy has to use - 7.3 km reach at 50 kt means the wall arrives before targets can react. Drop on probable lanes from cover, stay unspotted between waves, and let the wall do the work. 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.
The kit pays out by saturating lanes, not by waiting for guaranteed broadsides; missed waves still force rotations and protect your team's flank. Idle torpedo tubes are the worst output state. A second mistake to avoid: these torpedoes ignore the Destroyer class - they pass under DDs and cannot hit them. Aim torpedo drops ONLY at battleships, carriers, and most cruisers; every torp fired at a DD is wasted output.
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, shared by 2/24 T2 DDs.
+8% speed, 120 s duration. Engine Boost consumable temporarily raises top speed. Mobility on demand to reposition, chase a kill, or break contact.
30.0 s smoke deployment window, best of T2 DDs. Lays a longer rolling smoke trail while moving.
56.0 AA DPS, top decile of T2 DDs (median 10.0).
664.0 m/s HE muzzle velocity, bottom decile of T2 DDs. Lobby trajectory, harder to land at range.

Where Phra Ruang sits among Tier II DDs (24 ships). Notable standouts are shown first; the rest of the cohort-ranked stats are in the expand below. Acquisition variants (Black Friday, Founders Edition) are counted once with their base ship, not as separate peers.
Not standouts for Phra Ruang -- here's where she sits on every other ranked stat in the cohort. Stats tagged NORM are tied across more than half the cohort, so the value is the cohort default rather than a standout.

Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model: $\sigma_H = \left(\dfrac{R}{30}\cdot\dfrac{\text{idealRadius}-\text{minRadius}}{\text{idealDistance}} + \text{minRadius}\right)\cdot 30$ $= \left(\dfrac{7797}{30}\cdot\dfrac{8-0.5}{1000} + 0.5\right)\cdot 30 = 73.5\,\text{m}$Vertical dispersion ellipse height at max range: $\sigma_V = \sigma_H \cdot \text{radiusOnMax}$ $= 73.5 \cdot 0.6 = 44.1\,\text{m}$50%-hit horizontal radius: $\sigma_{H,50} = \sigma_H \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 73.5 \cdot 0.32\;(\sigma = 2) = 23.5\,\text{m}$50%-hit vertical radius: $\sigma_{V,50} = \sigma_V \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 44.1 \cdot 0.32\;(\sigma = 2) = 14.1\,\text{m}$Standard destroyer dispersion baseline.Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity: $P = 10^{-7}\cdot K \cdot m^{0.69} \cdot d^{-1.07} \cdot v_0^{1.38}$ $= 10^{-7}\cdot 1900 \cdot 14.1^{0.69} \cdot 0.102^{-1.07} \cdot 664^{1.38} = 106.4\,\text{mm}$. Matches the in-game spec card.Same formula at the ship's max firing range (10.7 km), where the shell has slowed to 228.7 m/s: $P = 10^{-7}\cdot 1900 \cdot 14.1^{0.69} \cdot 0.102^{-1.07} \cdot 228.7^{1.38} = 24.5\,\text{mm}$.17 mm ≈ 102 mm caliber / 6 (standard HE penetration ratio).floor(102 mm caliber / 14.3) = 7 mm (AP auto-penetrates plating this thick or less).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).

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.

Overmatched by 106+ guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.
Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 3%, fires burn 30s. Range-by-range in the ballistics tool →
| Section | Plates | HP cap | Threats | Tactic |
|---|---|---|---|---|
| Bow | 6 mm | 1,300 (15% of HP) | Overmatched by 127mm+ (Farragut, Shenyang)6 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. |
| Stern | 6 mm | 1,100 (13% of HP) | Overmatched by 127mm+ (Farragut, Shenyang)6 mm: HE pens from 127mm+ | Mirror of bow. Same fast saturation. |
| Citadel | 6 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 | 6 mm | 200 (2% of HP) | 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 | 4,400 magazine HP | Magazine detonation1–30% chance · below ~75% HP | Per-turret powder-magazine HP. Detonation chance scales from 1% (no mag damage) to 30% (full mag damage); this range is the in-game value. Detonation can't roll while the ship is above ~75% HP (the standard detonation-protection threshold, not a per-ship stat). Smaller magazines saturate to the 30% ceiling faster. |
| AA mount (40 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 | 2,600 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.
