Battle Levels

Haarlem — Dutch Tier VIII cruiser.

In 1939, the Dutch authorities decided to construct capital ships for their navy. Following lengthy discussions on what the new ship class should look like, it was determined that the main requirement was high speed. If deemed necessary, the ship needed to have a chance to avoid fighting against stronger opponents, such as Japanese Kongō-class battlecruisers. According to the project, the cruiser's displacement was 16,000 tons; she could accelerate up to 32–33 knots and carry 203 mm guns on board. But the armor of such a ship was considered insufficient by the naval committee, and the project was never completed.

Player Opinion

As the first large cruiser in the Dutch branch, Haarlem transitions away from her light cruiser predecessors and inherits the unique characteristics of high tier Dutch cruisers – above average durability, poor performing main battery guns, and powerful airstrikes.


For a cruiser, Haarlem is well protected. Her 25 mm bow is additionally protected by a 40 mm icebreaker, making it difficult to citadel her through the nose. Her midsection features a 30 mm deck, which is immune to overmatch from guns below 457 mm, and her 40 mm side plating allows her to ricochet battleship shells while angled. Her citadel is protected by a 200 mm main belt and 25 mm turtleback, the latter of which provides effective protection against cruisers. Haarlem however suffers from the same fire and flooding duration as battleships, making her survivability from damage over time poor.

Haarlem’s maneuverability is poor, with a top speed of 32.5 knots, and a rudder shift at 11.1 seconds when upgraded. Her concealment, on the other hand is excellent for a large cruiser, reaching 9.8 km when fully specced, which is superior to many other cruisers she can meet in-battle. She is able to take advantage of positions that many other cruisers cannot.


Haarlem is equipped with nine 203 mm guns, which are identical to same-tier cruiser Admiral Hipper in many aspects, including ballistics, AP penetration and HE fire chance. However, they are significantly worse in terms of reload, accuracy and range, as well as lacking her German counterpart’s improved HE pen. As a result, her damage output from her main battery is extremely poor, being similar to lower tiered cruisers. Captains should be mostly using HE shells to deal damage, regulating the AP to almost-perfect broadsides.

Haarlem also has access to the unique Dutch airstrike. As the first high tier cruiser in the line, Haarlem has access to two charges of the armament instead of one like the preceding cruisers. Their drop pattern, long reload and delay makes them most effective against large, immobile targets, such as battleships or bow-in island-hugging ships. A particularly useful tactic is using the airstrikes to set fires on enemy ships, forcing them to use their Damage Control PartyWhen activated, instantly repairs fires, floods, and incapacitations, and prevents more for the duration., and then using the main battery to set permanent fires.

Haarlem’s AA is well above average, with great range and good DPS values, in addition to having access to Defensive AA FireWhile active, the damage per second of large caliber anti-aircraft guns is increased.. While not as outstanding as her successors, her AA is a significant threat to Tier VI and VIII aircraft squadrons. Tier X carriers, however, can often get strikes off with little to moderate casualties.

Defining Consumables

Haarlem’s most unique consumable is her Repair PartyWhile active, restores a percentage of the ship's health points each second., which features an enhanced cooldown, only taking half the time of a standard one to reload. While her Hydroacoustic SearchWhile active, detects all enemy ships and torpedoes within the specified radius, without regard of obstacles such as smoke and terrain. and Defensive AA FireWhile active, the damage per second of large caliber anti-aircraft guns is increased. are standard for her tier, they are in separate slots, meaning captains don’t have to choose between taking one or the other.


Haarlem shines on the defensive. With her concealment, she can take aggressive positions, such as nearby islands, and use her airstrikes in tandem with her main battery to dissuade enemy ships from pushing in. She can also easily disengage and reposition to catch the enemies off-guard. Her armor and special Repair PartyWhile active, restores a percentage of the ship's health points each second. give her good survivability to hold down key positions.

Haarlem provides a relatively unique playstyle twist among cruisers, but pays for it dearly in other areas, primarily her main battery. Her damage output is poor, and her main battery accuracy is often aggravating. She provides new tools for captains to use in battle, but she will prove difficult to use them effectively.


  • Durable cruiser: Well armored midsection, icebreaker bow, and short Repair PartyWhile active, restores a percentage of the ship's health points each second. cooldown
  • Access to airstrikes with 2 total charges, 60 total bombs dropped, and good range
  • Good AA suite, aided by the Defensive AA FireWhile active, the damage per second of large caliber anti-aircraft guns is increased. consumable
  • Has the Hydroacoustic SearchWhile active, detects all enemy ships and torpedoes within the specified radius, without regard of obstacles such as smoke and terrain. and Defensive AA FireWhile active, the damage per second of large caliber anti-aircraft guns is increased. consumables in separate slots
  • Excellent concealment, can outspot the vast majority of cruiser in her matchmaking bracket
  • Good shell ballistics


  • Very weak main battery performance due to poor dispersion, limited range and slow reload
  • Low main battery DPM, essentially on par with Tier VI cruisers for effective damage output
  • Lacks torpedoes unlike most cruisers
  • Vulnerable to damage over time effects, with battleship duration fires and floods
  • Top speed and rudder shift are fairly sluggish
  • Rather long cooldown on airstrikes


Researchable module upgrades for Haarlem:

  • Hull: Upgrade to Hull (B) for more health and improved AA and maneuverability. Research of this module unlocks progression to Johan de Witt.
  • Gun Fire Control System: Upgrade to SUO Mk 8 Mod. 2 for an extra 10% range on the main battery.

Optimal Configuration


The recommended upgrades for Haarlem are:

In Slot 4, captains can opt to use Damage Control System Modification 2 : -15% flooding recovery time. / -15% fire duration. if they wish to minimize the damage from fires and floods.

Commander Skills


Haarlem can equip the following consumables:


Note: Use of the Juliet Charlie signal makes detonation impossible.
