Overview

Derzki is a Tier II Soviet long-range gunboat destroyer reaching 10.2 km: her guns out-reach peer DDs and most cruisers can be kited at the edge of her range. The kit is HE spam from open water rather than cap contesting; the torpedoes are a backup, not the primary threat. Standout traits: best HE fire chance in T2 DDs (7) and best DCP duration in T2 DDs (10 s).

Positioning

Sit in open water at the edge of 10.2 km where peer DDs cannot return fire and most cruisers have to push to engage. The kit is HE pressure from distance, not cap contesting; let your peer DDs take the cap while you kite the rotating cruisers and BBs that come to support it. 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

Overstaying detection after a torpedo drop

The detection window is a hard timer; if you are still firing guns when concealment closes again, you have already taken more damage than the drop earned.

Signature Traits

Maximum simulated damage
ƒEstimate 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: Dsim=α·c=16,100·0.333=5,367.

Base value; commander torpedo-concealment skills lower it further. Community torpedo-reaction calculator by u/LorenDovah and u/The_ColorOutofSpace.

Flooding chance
ƒRead straight from the game's own data: this torpedo carries a flooding-chance value of 0.96 per hit, shown as 0.96×100=96%. 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.

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 (8 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 HP2,900 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.
