Player Opinion


Tier VIII Premium Cossack is a comfortable blend of firepower and concealment. Captains will notice many similarities between Cossack and Tier VII Premium Commonwealth destroyer Haida. Her performance is very similar and she shares many of the same strength and weaknesses as her sister ship. The most obvious difference between the two ships if the number of main battery rifles, with Cossack bringing an extra pair of them to the fight.

The guns on Cossack are plentiful and provide the ship with excellent firepower, although captains will note the firing angles on the 'Y' turret are quite poor; Cossack must expose a lot of her profile in order to bring all four turrets into a fight. However, when she does manage to get all her guns firing, she boasts an impressive damage rate with her HE shells (complimented by a base fire chance of 8%). This presents Cossack with almost unrivaled gun power for her tier, capable of quickly dispatching of destroyers that get caught out by her good concealment.

Cossack’s Smoke Generator (While active, generates a smoke screen that blocks line-of-sight for both enemies and teammates.) provides her with a quick smoke screen which will allow her to bring her guns into play before before she is forced to move on by the relatively short duration of her smoke. This does, however, promote usage of her smoke primarily for defensive play, as she is able to deploy it to quickly break line of sight with pursuing enemy ships. Captains of Cossack will find that because of the relatively short smoke duration they are forced to re-position frequently, but her excellent concealment blends well with this.

Cossack also gains access to a Hydroacoustic Search (While active, detects all enemy ships and torpedoes within the specified radius, without regard of obstacles such as smoke and terrain.); however, she trades most of its offensive usability for defensive flexibility. Despite being very short-ranged (only 3.0 km), it provides plenty of forewarning about hostile torpedoes. The long duration of this consumable helps to ensure Cossack captains are almost never caught out by hostile torpedoes, able to keep themselves safe during prolonged confrontations. Captains may also opt to use her hydro in a more aggressive manner by pushing close to enemy smoke screens that may have destroyers lurking within, but the short range of her hydro makes doing so a fairly risky play. However, the Hydroacoustic Search (While active, detects all enemy ships and torpedoes within the specified radius, without regard of obstacles such as smoke and terrain.) is less than ideal for this task as it falls short on spotting range when compared to that of other destroyers at her tier, such as German Z-23 or Pan-Asian Loyang.

Another of Cossack’s key strengths is her excellent concealment. Her low base detection range allows her to deal with enemy destroyers while providing her with the flexibility to control an engagement, choosing when and where to open fire. Her concealment provides her with a buffer zone against other destroyers, allowing Cossack to evade ships which outgun her, while outgunning ships which out-spot her. Her smoke screen benefits her when used to enable such a play style, allowing her to break detection and disengage if required.

Things are not all smooth sailing for Cossack though, and she has a few glaring weaknesses. Her foremost issue is her torpedoes, which — although good — are lacking in quantity, as she mounts only a single quadruple-tube launcher. On top of this, the restrictive gun angles of her main battery can also limit the true effectiveness of her guns during close quarter duels. This, when combined with her relatively small health pool can make close quarter duels a somewhat risky business. Lastly, her anti-aircraft defenses are inadequate even for self-defense, so captains must fall back to their team for defense against enemy air attacks.

Captains of Cossack will find the most success using her concealment to sneak upon unsuspecting destroyers and from here pushing into a knife fight to secure the kill. This will allow her to ensure her guns land as many hits as possible, using a mix of her single launch torpedoes and high DPM main battery. Careful and calculated usage of her Smoke Generator (While active, generates a smoke screen that blocks line-of-sight for both enemies and teammates.) will allow captains to effectively fight or flee from any enemy ships will allow Cossack to best perform her role as a defensive scout, providing spotting for the team and probing around caps while remaining close to friendly ships to deter attacks from hostile destroyers.


  • Powerful main battery: eight guns with a rapid rate of fire.
  • Decent torpedoes with good damage, speed, range, and reload.
  • Can equip the Hydroacoustic Search (While active, detects all enemy ships and torpedoes within the specified radius, without regard of obstacles such as smoke and terrain.) consumable, giving her superior detection abilties.
  • Good maneuverability, with good rudder shift, turning radius, and a decent top speed.
  • Great concealment, superior to all other same-tier destroyers except those of Japan (excluding Akizuki).


  • Smoke from Smoke Generator (While active, generates a smoke screen that blocks line-of-sight for both enemies and teammates.) disperses very quickly.
  • Only one set of torpedo tubes; can only put four torpedoes in the water at a time.
  • Virtually non-existent anti-aircraft armament.
  • Torpedo range may be inadequate in Tier X matches where ships with long-range Surveillance Radar (While active, detects all enemy ships within the specified radius, disregarding obstacles such as smoke and terrain.) range are abundant.
  • Single torpedo launcher has a narrow forward firing arc, not much beyond 90 degrees off either side.


As a Premium ship, Cossack doesn't have any upgrades to research.

Optimal Configuration


As a Tier VIII Destroyer, Cossack gets significant benefits from some upgrades. As a ship that makes use of not being seen, Concealment System Modification 1 (-10% to detectability radius. / +5% to the maximum dispersion of enemy shells that fire on your ship.) is vital. Players who wish to avoid detonations without running the appropriate flag may want to use Magazine Modification 1 (-70% to the risk of your ship's magazine detonation.), and those who use the flag will get use out of Main Armaments Modification 1 (-20% to the risk of main battery becoming incapacitated. / +50% to main battery survivability. / -20% to main battery repair time. / -20% to the risk of torpedo tubes becoming incapacitated. / +50% to torpedo tubes survivability. / -20% to torpedo tubes repair time.). Propulsion Modification 1 (-20% to the risk of the engine becoming incapacitated. / -20% to engine repair time.) or Steering Gears Modification 1 (-20% to the steering gears repair time. / -20% to the risk of the steering gears becoming incapacitated.) are both good choices depending upon which ailment the player wants more protection from. Aiming Systems Modification 1 (-7% to maximum dispersion of main battery shells. / +20% to torpedo tubes traverse speed. / +5% to secondary battery maximum firing range. / -5% to maximum dispersion of secondary shells.) is useful in the third slot for the increased torpedo tube traverse rate and decreased dispersion. Cossack is unable to mount Propulsion Modification 2 (-50% to time for reaching full power. / Increases engine power when the ship starts moving.) so she is forced to choose between Steering Gears Modification 2 (-20% to rudder shift time.) or Damage Control System Modification 2 (-15% to flooding recovery time. / -15% to time of fire extinguishing.).

The recommended upgrades for Cossack are as follows:

Commander Skills

Key skills for Cossack commanders include Last Stand, Survivability Expert, and Concealment Expert.


Cossack can equip the following consumables:

It is recommended that captains use Premium consumables to get the most out of the ship.


As a Premium ship, Cossack comes included with Type 10 camouflage that lowers her detection radius, reduces the accuracy of incoming shells, reduces her repair costs, and increases the amount of experience she earns.


Cossack captains should mount standard signal flags to improve the ship's performance in battle. Sierra Mike (+5% to the ship's maximum speed.) signal flags are highly recommended to increase the ship's top speed. Victor Lima (+1% chance of causing a fire for bombs and shells with a caliber above 160mm / +0.5% chance of causing a fire for bombs and shells with a caliber below 160mm. / +4% chance of causing flooding.) and India X-Ray (+1% chance of causing a fire for bombs and shells with a caliber above 160mm. / +0.5% chance of causing a fire for bombs and shells with a caliber below 160mm. / +5% to the risk of your ship's magazine detonating.) flags can be mounted to improve the ship's main battery fire chance. November Foxtrot (-5% reload time on all consumables.) is also recommended to reduce consumable cooldown timers. Lastly, economic and special signal flags can be mounted to increase the ship's economic gains per battle.
