Delny is a Tier VIII Soviet gunboat destroyer: her damage comes from sustained main battery pressure on caps and open-water trades. Torpedoes are a secondary threat for closing lanes, not her main damage. Standout traits: best armor plate in T8 DDs (50 mm) and best engine power in T8 DDs (150,000 HP).
Hold mid-cap distance and lean into gunboat trades from cover where the peer destroyer cannot match your fires-per-minute. Avoid open-water duels with ships running smoke or radar; your damage is mostly gunfire, and gunfire from cover wins more than from blue water. 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.
Your damage is sustained main-battery pressure from cover (the torpedoes are a secondary threat), so open-water duels just stack incoming HE on you while you fire back.
+8% speed, 120 s duration. Engine Boost consumable temporarily raises top speed. Mobility on demand to reposition, chase a kill, or break contact.
28.0 s Repair Party duration, best of T8 DDs. Restores HP for longer per activation.
7.61 km surface detect, worst of T8 DDs. Visible before you can react; position early.

Numbers the spec table cannot show directly: alpha-strike math, DPM, dispersion, AP penetration. Click the formula chip on any row to reveal how it is calculated.
Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model: $\sigma_H = \left(\dfrac{R}{30}\cdot\dfrac{\text{idealRadius}-\text{minRadius}}{\text{idealDistance}} + \text{minRadius}\right)\cdot 30$ $= \left(\dfrac{10090}{30}\cdot\dfrac{8-0.5}{1000} + 0.5\right)\cdot 30 = 90.7\,\text{m}$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.Vertical dispersion ellipse height at max range: $\sigma_V = \sigma_H \cdot \text{radiusOnMax}$ $= 90.7 \cdot 0.6 = 54.4\,\text{m}$How tall the same scatter ellipse is at 10 km. Comparable from ship to ship for the same reason as the width value above.50%-hit horizontal radius: $\sigma_{H,50} = \sigma_H \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 90.7 \cdot 0.32\;(\sigma = 2) = 29\,\text{m}$50%-hit vertical radius: $\sigma_{V,50} = \sigma_V \cdot \text{GetHalfHitsRatio}(\sigma)$ $= 54.4 \cdot 0.32\;(\sigma = 2) = 17.4\,\text{m}$Standard destroyer dispersion baseline.Canonical community AP formula (jcw780/wows_shell), evaluated at muzzle velocity: $P = 10^{-7}\cdot K \cdot m^{0.69} \cdot d^{-1.07} \cdot v_0^{1.38}$ $= 10^{-7}\cdot 1900 \cdot 33.4^{0.69} \cdot 0.13^{-1.07} \cdot 950^{1.38} = 244\,\text{mm}$. Matches the in-game spec card.Same formula at the ship's max firing range (13.9 km), where the shell has slowed to 376.8 m/s: $P = 10^{-7}\cdot 1900 \cdot 33.4^{0.69} \cdot 0.13^{-1.07} \cdot 376.8^{1.38} = 68.1\,\text{mm}$.22 mm ≈ 130 mm caliber / 6 (standard HE penetration ratio).floor(130 mm caliber / 14.3) = 9 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). Larger value = bigger splash damage area when AP over-pens.All 6 barrels bear on the broadside.180 degrees / 13 deg/s traverse speed = 13.8 s.2,050 HE damage x 6 broadside guns = 12,300.2,850 AP damage x 6 broadside guns = 17,100.12,300 HE full-salvo alpha x 60 / 5 s base reload = 147,600.17,100 AP full-salvo alpha x 60 / 5 s base reload = 205,200.12,300 HE full-salvo alpha x 60 / 4.5 s installed reload (Main Battery Mod. 3 = -10%) = 164,000.17,100 AP full-salvo alpha x 60 / 4.5 s installed reload (Main Battery Mod. 3 = -10%) = 228,000.6 broadside guns x 60 / 5 s base reload = 72.6 broadside guns x 60 / 4.5 s installed Artillery reload = 80.72 shells/min x 8% fire chance = 5.76.80 shells/min x 8% fire chance = 6.4.detectability / (speed kt x 2.6 community game-speed factor).range / (speed kt x 2.6 community game-speed factor).2 launchers x 5 tubes.10 (centerline launchers train across - full salvo to either side).All tubes hitting one target: tubes x per-torpedo simulated damage = 10 x 13,400 = 134,000.One side firing, all torpedoes hitting: per-side tubes x per-torpedo simulated damage = 10 x 13,400 = 134,000.Sum across every AA aura on this ship of (aura.continuous_damage x 3.5 x aura.hit_probability).

Covers AA-only mounts plus dual-purpose secondaries (Bismarck 105mm, USN 5"/38 cruiser secondaries) and dual-purpose main batteries (Sumner-class 5"/38, Akizuki-line 100mm). Formula validated against in-game captures on California, Sumner, Manfred von Richthofen, Dante Alighieri (exact) and within +/-17% on the remaining verified ships.Longest-reaching aura across AA-only + dual-purpose auras.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.Hull HP 20,000 → 22,000 with hull upgrade, 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.
Overmatched by 129+ guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.
Thin belt: battleship AP citadels straight through it broadside. Rely on angle, speed and concealment, never sit flat.
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 ballistics tool →
| Section | Plates | HP cap | Threats | Tactic |
|---|---|---|---|---|
| Bow | 19 mm primary (range 19–20 mm) | 2,000 (9% of HP) | Overmatched by 283mm+ (Scharnhorst '43, Schill)Angle bounces 203mm19 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) | 19 mm primary (range 19–20 mm) | 17,000 (77% of HP) | Overmatched by 283mm+ (Scharnhorst '43, Schill)Angle bounces 203mm19 mm: HE pens from 127mm+ | Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest. |
| Stern | 19 mm primary (range 19–20 mm) | 1,900 (9% of HP) | Overmatched by 283mm+ (Scharnhorst '43, Schill)Angle bounces 203mm19 mm: HE pens from 127mm+ | Mirror of bow. Same fast saturation. |
| Citadel | 50 mm primary (range 13–50 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 | 19 mm | 2,900 (13% 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 | 11,400 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 (45 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 | 6,800 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.
