Overview

Chung Mu is a Tier VIII 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. Standout traits: best turret traverse rate in T8 DDs (34) and top-decile torpedo detection in T8 DDs (0.8 km).

Positioning

Sit at the edge of a contested cap from concealment and cycle torpedo waves into lanes the enemy has to use - 10.5 km reach at 66 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.

Potato Avoidance

Holding 10.5-km torpedoes for a perfect shot

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.

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, shared by 2/27 T8 DDs.

Surveillance Radar

7.5 km range, 17 s duration. Detects all enemy ships within a fixed radius regardless of line-of-sight. Controls caps and punishes smoke-firing DDs.

Engine Boost

+8% speed, 120 s duration. Engine Boost consumable temporarily raises top speed. Mobility on demand to reposition, chase a kill, or break contact.

Long smoke deployment

30.0 s smoke deployment window, top decile of T8 DDs. Lays a longer rolling smoke trail while moving.

Fast turret traverse

34.0°/s turret traverse, best of T8 DDs. Tracks fast-rotating targets peers can't keep up with.

Stealthy torps

0.8 km torpedo detect, top decile of T8 DDs. Harder to dodge.

Acquisition

How to get Chung Mu

Chung Mu is available in the Capital Ship Destroyers branch of the Pan-Asia Tech Tree for 25,000,000 credits after researching it in the branch. Known module upgrades cost up to 6,250,000 credits.

Max Horiz Disp91.3 m
Horizontal dispersion ellipse width at max range, from the verified WoWS dispersion model: $\sigma_H = \left(\dfrac{R}{30}\cdot\dfrac{\text{idealRadius}-\text{minRadius}}{\text{idealDistance}} + \text{minRadius}\right)\cdot 30$ $= \left(\dfrac{10176}{30}\cdot\dfrac{8-0.5}{1000} + 0.5\right)\cdot 30 = 91.3\,\text{m}$
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.

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 HP200 per-mount HPDestroyed at 0 HPPer-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 HP5,100 module HPIncapacitated at 0 HPWhen 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.
