Battle Levels

Johan de Witt — Dutch Tier IX cruiser.

An alternative project to the one for the cruiser from back in 1939—it preserved the armament comprising nine 240 mm guns and offered appropriate armor and speed but presupposed greater displacement. Thanks to her high speed, such a cruiser could avoid engaging her enemies if she so wished while also being able to stand up against several Japanese battlecruisers due to her enhanced armament and armor. However, that project was never implemented either. Further work was focused on designing a heavy cruiser carrying 283 mm main guns.

Player Opinion

As the penultimate Dutch cruiser, Johan de Witt stands out among her peers with her good armor, large (albeit poor performing) guns, the unique Dutch airstrike, and great concealment.


As with her predecessor Haarlem, Johan de Witt features an above average armor scheme for a cruiser. Her midsection is well protected, with a 225 mm main belt and 25 mm turtleback protecting her citadel from most cruisers. Against battleships, her 27 mm side plating allows her to effectively ricochet their shells while angled. Her 30 mm deck makes her immune to overmatch from shells of up to 406 mm. Finally, her 25 mm bow is additionally protected by a 40 mm icebreaker, making bow-on overmatch difficult. However, her 25 mm stern remains vulnerable to enemy battleships. Captains should also be aware of Johan de Witt’s Achilles' heel: Damage over time. She suffers from the same fire duration and flooding damage as battleships.

Johan de Witt also suffers from rather poor maneuverability. She is one of the slowest Tier IX cruisers at 32.1 knots. Her sluggish 11.9 rudder shift can also catch captains off guard, though her turning circle is on the tighter end at 740 m. Where Johan de Witt stands out the most is her concealment. With all modifiers she reaches a minimum detection of 10 km, among the best of all Tier IX cruisers. This allows her to dictate her engagements against enemy ships, as well as take aggressive positions in battle.


Johan de Witt is equipped with nine 240 mm guns, which are on the larger end of gun calibers for Tier IX tech tree cruisers, bringing an acceptable turret traverse for their size. With a decent fire chance of 20%, they will be the primary shell choice for captains, though her HE damage output is low due to the slow 16 second reload on her guns. On paper, her AP shells are great, with good penetration and damage values. In practice, however, they are hampered by the poor dispersion and low rate of fire of Johan de Witt’s guns. Thus, her AP is regulated to broadsides and overmatching cruisers with 16 mm plating, such as Neptune and Sejong.

As a high tier Dutch cruiser, Johan de Witt also has access to two charges of the unique Airstrike armament. With their long delay and reload, they are most effective against slow or immobile targets, and are useful at digging out island-hugging ships. Their drop pattern means they should ideally be used against ships that are bow or stern in. Used in conjunction with her HE, Johan de Witt can be a decent firestarter, lighting up ships that used their Damage Control PartyWhen activated, instantly repairs fires, floods, and incapacitations, and prevents more for the duration. to set permanent fires.

Johan de Witt’s AA suite is one of the best at her tier, with her 3.5 km mid-range AA having the best DPS for Tier IX cruisers. Coupled with her Defensive AA fire, she is a threat to all aircraft squadrons that approach her, either destroying or severely crippling them.

Defining Consumables

Like Haarlem, Johan de Witt has access to a Repair PartyWhile active, restores a percentage of the ship's health points each second. with an improved cooldown, allowing her to stay in the fight longer, and survive under intense focus fire. She also has access to both 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. simultaneously, although both are the standard versions of the consumables.


With her outstanding concealment and great armor, Johan de Witt is ideal in holding aggressive positions. Her heal and armor allow her to survive under pressure from enemy ships. If needed, she can disengage from the fight and reposition to a safer location. She can either be played aggressively at close to mid range, or played as a typical long-range cruiser when equipped with Gun Fire Control System Modification 2 : +16% firing range., using her HE shells and airstrikes to lock down enemy ships.

Johan de Witt is a decent all-round cruiser with access to unique tools, namely her airstrike and concealment. While she pays a price in main battery performance for them, she is relatively flexible to most situations that can occur in battle.


  • Large gun caliber for a Tier 9 tech tree cruiser at 240 mm
  • Powerful AP shells with good damage, penetration and shell velocity
  • Heavily armored midsection and icebreaker bow
  • Second strongest airstrike among Dutch cruisers, only beaten by Gouden Leeuw
  • Very powerful AA defenses, aided by the Defensive AA FireWhile active, the damage per second of large caliber anti-aircraft guns is increased. consumable
  • Improved Repair PartyWhile active, restores a percentage of the ship's health points each second. consumable with a fast cooldown
  • Amazing concealment for such a vessel, as low as 10 km with all relevant upgrades


  • Short main battery range
  • Poor main battery rate of fire
  • Subpar main battery accuracy
  • While fire chance is decent, HE damage output is very low
  • Like all Dutch large cruisers, Johan de Witt has increased fire and flood duration (same as a battleship)
  • Airstrikes have a fairly long cooldown
  • Slow rudder shift for a cruiser


Availability of researchable upgrades for Johan de Witt is as follows:

  • Hull: Upgrade to Hull (B) for a faster rudder shift time, improved AA, and more HP. Research of this module unlocks progression to Gouden Leeuw.
  • Gun Fire Control System: Upgrade to SUO Mk 9 Mod. 2 for an extra 10% range on the main battery.

Optimal Configuration


The recommended upgrades for Johan de Witt are as follows:

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.

In Slot 6, captains can choose Main Battery Modification 3 : -12% main battery loading time. / -13% main battery traverse speed. to improve Johan de Witt’s slow reload and be tailored towards closer-ranged engagements, or Gun Fire Control System Modification 2 : +16% firing range. to improve her short firing range as well as slightly improve her vertical dispersion.
