Overview

Acasta is a Tier IV British smoke destroyer with 6 smoke charges on a short cooldown: the many smokes are the kit, setting up aggressive and defensive plays that one-smoke DDs cannot. Hold cap edges and trade gunfire from cover, then re-smoke before the next window closes. Standout traits: top-decile quick acceleration in T4 DDs (6.3 s) and top-decile torpedo alpha in T4 DDs (14,633).

Positioning

Anchor near a smoke cycle on a contested cap and trade gunfire from inside the cloud. The smoke is your sustain tool; rotating mid-smoke wastes the cycle 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 2.1 km, and a destroyer here is spotted at about 6 km, so you see it coming with roughly 3.9 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 3.7 km) reads straight in regardless. At 600 m the screen is wider than standard, so it can cover a teammate holding the same line as well as your own hull. Once the rudder is over she turns tightly for her cohort (540 m), so a committed turn costs less water than most of what she is fighting.

Potato Avoidance

Rotating mid-smoke

The smoke is a static firing position; if you leave it before the cycle ends, you give up the trade you set up and the next contest opens without a smoke to fall back on.

Fire resistance

Does not reduce the damage a burning fire does per second: replay-measured burn ticks run at the full rate on every ship. By elimination it lowers how often hits set you on fire; ignition-rate replay data is consistent with that but too confounded by attacker mix to measure the reduction directly.

Initial: 13.3% → 16.6%

Fire duration30 s

Fire damage

Each fire ticks 0.3% of max HP per second for the full 30 s, so one unattended fire burns 9% of the pool (1,008 HP on this ship). 4 fire points can burn at once. Verified against measured burn ticks in replay data.

0.3% of HP per second

Flood duration40 s

Flood damage

A flood ticks 0.25% of max HP per second for the 40 s duration, so one unattended flood costs 10% of the pool (1,120 HP on this ship). Verified against measured flood ticks in replay data.

0.25% of HP per second

Torp Reduction

Reduces torpedo hit damage. Replay data shows no effect on floods: flood ticks run at the full rate and flood frequency does not decline with protection.

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.

Turret traverse arcs

How far each mount can train, in degrees to either side of the mount's own facing, read from in-game data. 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.

2x ±150°, ±125°, ±147°

Guns to bear

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. Mount facing is inferred from turret stations and verified against known layouts, including Izumo's aft-facing forward turret.

P = 10^{- 7} \cdot K \cdot m^{0.69} \cdot d^{- 1.07} \cdot v_{0}^{1.38}

= 10^{- 7} \cdot 2396 \cdot {22.68}^{0.69} \cdot {0.12}^{- 1.07} \cdot 808^{1.38} = 205.3 mm

. Matches the in-game spec card.

Torpedoes

ModuleTorpedoes: 533 mm Mk VII

Launchers / tubes2 launchers × 4 tubes = 8 tubes

Reload time

Base reload of the top torpedo module (all-upgrades configuration); the stock module reloads in 95 s. In-game port tooltips additionally fold in your installed modernizations and commander effects - e.g. Torpedo Launchers Mod. 3 alone is x0.85:

106 \times 0.85 = 90.1

106 s

Projectile speed59 kt

Range6 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 = 43, 900 \cdot 0.333 = 14, 633

≈ 14,633

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.

15,733

Torpedo detectability1.2 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{1.2 km}{59 kt \times 2.6855} = 7.6 s

. The 2.6855 m/s-per-knot game-speed factor is calibrated from in-game measurement; the community's traditional 2.6 reads about 3% slower. 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 2.62 per hit, shown as

2.62 \times 100 = 262 %

. 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.

Reverse speed

top speed / 4 + 4.9 = 35 / 4 + 4.9 = 13.7 kt. The community reverse-speed model from the WoWs ShipBuilder project, the same source as the acceleration model on this card. Base value; speed modifiers scale it. Not shown on the in-game card.

13.7 kt

Crash stop

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. Same community-model simulation as the acceleration times, using the ship's own reverse-power ratio from in-game data. The full curve is on the acceleration chart.

14.3 s

Engine boost threshold (reverse)

Speed below which the engine's built-in power boost applies in reverse. Matches the in-game maneuverability card's reverse threshold (Vampire II reads 10.5 here and the card shows 11; the card rounds half up).

9.7 kt

Acceleration 0-90%

Time to reach 90% of top speed (31.5 kt of 35 kt), from our in-house acceleration model.

6.3 s

Acceleration 0-99%

Time to reach 99% of top speed (34.6 kt of 35 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.

17.1 s

Traverse-to-turn ratio

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

ω_{hull} = \frac{180}{π} \cdot \frac{V_{max} (m/s)}{R_{turn}} = \frac{180}{π} \cdot \frac{35.0 \cdot 0.5144}{540} = 1.91 ° / s

, so

ratio = \frac{ω_{turret}}{ω_{hull}} = \frac{10}{1.91} = 5.2 \times

. Below 5 the turrets drag in a turning fight; 25+ keeps up with any rudder.

AA defense

AA DPS at max range35

Only families that reach 2.5 km contribute at the outer edge of the AA bubble. In-game families: 2pdr QF MKII PomPom 2x1 -> 35 DPS @ 2.5 km; 12mm62 HI 2x4 -> 13 DPS @ 1.2 km.

Maximum AA range2.5 km

Longest-reaching family on the in-game AA card. Base AirDefense aura max range is 2.5 km; dual-purpose mount auras extend it.

AA DPS layered by range35 DPS @ 2.5 km, 48 DPS @ 1.2 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-blank48

Sum of every family's average DPS, achievable only inside the closest-range family (1.2 km).

AA threat index103

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 range1.2 km

Armor Beta

Hull HP 9,500 → 11,200 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.

Bow & stern10 mm

Overmatched by 134+ AP guns across the bracket. Can’t reliably bow-tank; gets bow-citadelled and overpenned.

Farming10 mm

Superstructure and extremities take HE pens and AP overpens from nearly any gun: steady chip damage. Fire resistance 17%, fires burn 30s. Range-by-range in the Compare tool →

Section	Plates	HP cap	Threats	Tactic
Bow	10 mm	1,600 (14% of HP)	Overmatched by 150mm+ AP (De Ruyter, Karlsruhe)Angle bounces 127mm10 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	10 mm	1,200 (11% of HP)	Overmatched by 150mm+ AP (De Ruyter, Karlsruhe)Angle bounces 127mm10 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	10 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	10 mm	600 (5% 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	5,600 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 (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	3,400 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.
