Overview

Z-23 is a Tier VII German stealth-leaning destroyer with strong surface detection (6.8 km). The kit opens detection windows most peer DDs cannot match, so her value is contesting caps from concealment edges where the detection band holds. Standout traits: top-decile tight dispersion in T7 DDs (87.6 m).

Positioning

Hold concealment edges on the contested cap at 6.8 km detection. The band opens windows for unspotted torpedo drops and clean repositions; lean into the gaps your peer DDs cannot read, and back out before detection closes. 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

Burning the 6.8 km concealment advantage on guns

Every salvo lights you up and gives back the detection edge that makes the kit work; reserve guns for finishing damage on already-spotted ships, and prioritize torpedo drops you can fire while undetected.

Signature Traits

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.

ELITE ARMOR
  • Bow-tanker
  • Heavy belt
Short gun range

10.64 km main battery reach, bottom decile of T7 DDs. Outranged by peers; close distance or lean on terrain.

Acquisition

How to get Z-23

Z-23 is available in the Area-Control Destroyers branch of the Germany Tech Tree for 18,000,000 credits after researching it in the branch. Known module upgrades cost up to 4,950,000 credits.

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.

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 (37 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 HP5,900 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.
