Battle Levels

Iowa — American Tier IX battleship.

One of the most powerful battleships of World War II. The ship was designed for escorting attack carrier forces. She surpassed the speed of all battleships in the world. The battleship's survivability was significantly improved owing to a novel and powerful torpedo protection system and a fundamentally different armor protection system featuring an internal armor belt.

All four Iowa-class ships built are now preserved as military museum ships: USS Iowa in San Pedro, California; USS Missouri in Pearl Harbor, Hawaii; USS Wisconsin in Norfolk, Virginia; and USS New Jersey in Camden, New Jersey.

Player Opinion


The historical counterpart of the famed battleship Yamato, Tier IX's Iowa is the pinnacle of the various fast battleship designs the United States commissioned into service before and during World War II.

Veterans of North Carolina will be well-familiar with how Iowa plays, as both ships are laid out in an identical AB-X turret arrangement. The key differences are found in Iowa’s handling — she is faster, with a larger turning circle and slower rudder shift speed — slightly improved AA suite, and longer main battery rifles. Iowa’s barrels are 50 caliber (as opposed to North Carolina’s 45 caliber) and the improvement in the velocity of her armor-piercing shells is notable. Her AP shells get on target faster, and new Iowa captains should allow a few games to learn how to adjust leading their shots accordingly. Additionally, she gains access to Artillery Plotting Room Modification 2 (-11% to maximum dispersion of main battery.), which provides a significant reduction to her dispersion.

Exposing her flat broadside to enemies is as inadvisable in as it is in most battleships. Even with her citadel model lowered to the ship's third deck at roughly waterline height in Update 0.6.6, the third deck plating can be overmatched by every battleship in her matchmaking spread. Consequently, Iowa will still be dealt catastrophic damage, and quite consistently by those with good aim. Careful positioning and good situational awareness are still required at all times to ensure she isn't removed from the game in a single enemy salvo, and this vulnerability makes fighting at close ranges very tricky as her overall length is more of a liability than an asset.

Once mastered, however, Iowa’s capabilities are unmatched by just about any battleship in game. She combines speed, firepower, and survivability in a way that is unrivaled by any other ship in her tier and below. Her mobility allows her to get to where she is needed, her powerful super-heavy shells allow her to put good damage whatever she encounters there, and her armor allows her to tank punishment provided she don't expose her broadside or get blindsided by incoming torpedoes.


  • Same gun range as her predecessor and highest range for a battleship at her tier.
  • Better penetration and shell velocity compared to North Carolina due to the 50 caliber gun.
  • Able to mount Artillery Plotting Room Modification 2 (-11% to maximum dispersion of main battery.) for better dispersion.
  • Armor is more durable than predecessors.
  • Incredible anti-aircraft suite makes her highly resistant to aerial assault.
  • Improved torpedo defense system with a torpedo damage reduction of 27% (compared to North Carolina’s 19%).
  • Top speed of a whopping 33 knots.


  • Weaker broadside armor than standard battleships, but still stronger broadside armor than North Carolina.
  • Bad rudder shift time (over 20 sec) until Hull (C).
  • Overall length combined with her turning circle takes some getting used to when trying to dodge torpedoes.
  • While at waterline level, the citadel is very long and the roof can be overmatched by every battleship in her matchmaking spread.
  • Very tall superstructure makes her easier to hit, especially when trying to hide behind islands.
  • Weak secondary armament with a very low range compared to Tier IX counterparts Izumo, Friedrich der Große, and Alsace.


Availability of researchable upgrades for Iowa is as follows:

  • Hull: Upgrade to Hull (B) for an additional 10,000 hit points and an improvement to her mid- and short-range AA bubbles. Upgrade to Hull (C) for faster rudder shift and further enhancements to her AA suite. Research of Hull (C) unlocks progression to Montana.
  • Gun Fire Control System: Upgrade to Mk9 mod. 2 for an extra 10% range on the main battery.
  • Propulsion: The propulsion upgrade bumps Iowa’s speed from 28.8 knots to her historical maximum of 33 knots.
Investing experience into Hull (B) is top priority; it brings additional hit points and a large bump to Iowa’s anti-aircraft capabilities. The Propulsion module upgrade should come next, followed by Hull (C), with the Fire Control System upgrade saved for last.

Optimal Configuration


The recommended upgrades for Iowa are as follows:

Commander Skills


Iowa can equip the following consumables:

Even captains which do not opt for a maximum survivability build are encouraged to spend credits (or doubloons) on Repair Party II (While active, restores a fixed percentage of a ship's hit points each second.) and Damage Control Party II (When activated, instantly repairs fires, floods, and incapacitations, and prevents more for the duration.) for the shorter cooldown times of each.


Type 1, 2, or 5 camouflage can be equipped for credits; Types 2 or 5 are recommended at a minimum to reduce the accuracy of incoming shells.

Players who wish to spend doubloons can equip Iowa with Type 19 camouflage that lowers her detection radius, reduces the accuracy of incoming shells, reduces her repair costs, and increases the amount of experience she earns.


Iowa’s signal loadout should focus on two objectives: maximizing her experience earnings and maximizing her survivability. Equal Speed Charlie London (+50% XP earned for the battle.), Hydra (+50% XP earned for the battle. / +150% Commander XP earned for the battle. / +250% Free XP earned for the battle.), and Red Dragon (+100% XP earned for the battle. / +100% Commander XP earned for the battle.) will help with the former, while India Delta (+20% to the amount of HP recovered when the Repair Party consumable is used.), India Yankee (-20% to fire duration.), and Juliet Yankee Bissotwo (-20% to flooding duration.) will help with the latter. Sierra Mike (+5% to the ship's maximum speed.) is worthy of consideration for captains who enjoy flexing Iowa’s speed, while November Foxtrot (-5% reload time on all consumables.) and November Echo Setteseven (+5% continuous damage by all AA guns, +5% damage per second within the explosion radius of shells fired from medium- and long-range AA defenses.) will help reduce her consumable cooldowns and further enhance her AA suite.
