Iowa — Encouraçado Americano Tier IX.

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.

Performance

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 barrels) 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 Predefinição:Artillery Plotting Room Modification 2, which provides a significant reduction to her dispersion.

Exposing her flat broadside to enemies is as inadvisable in Iowa as it is in most battleships. Even though her citadel is at the ship's third deck at roughly waterline height, the third deck plating can be overmatched by every battleship in her matchmaking spread. Consequently, Iowa can be dealt catastrophic damage by well-aimed AP shells. Careful positioning and good situational awareness are 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 inflict significant damage on whatever she encounters there, and her armor allows her to tank punishment provided she doesn't expose her broadside or get blindsided by incoming torpedoes.

Prós:

• Same gun range as her predecessor and can go up to 27km when fully upgraded, which is the highest range for a battleship at her tier.
• Powerful hard hitting AP shells that make citadel hits on enemy ships painfully felt.
• Better penetration and shell velocity compared to North Carolina due to the 50 caliber gun.
• Able to mount Predefinição:Artillery Plotting Room Modification 2 to improve accuracy.
• Armor is more durable than her predecessor North Carolina
• 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%).
• Decent ship speed of 33 knots which makes her among the fastest battleships in the game..
• Good firing angles, meaning that not much board side is needed to fire all guns on a target.

Contras:

• Weaker broadside armor than standard battleships, but still stronger broadside armor than North Carolina.
• Bad rudder shift time (over 20 sec) until Hull (B).
• Iowa's dispersion is poor at range without Predefinição:Artillery Plotting Room Modification 2.
• 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 deck plating can be overmatched by every battleship and large cruisers in her matchmaking spread.
• Very tall superstructure makes her easier to hit.
• Weak secondary armament with a very low range compared to Tier IX counterparts Izumo, Friedrich der Große, and Alsace.

Pesquisar

Availability of researchable upgrades for Iowa is as follows:

• Hull: Upgrade to Hull (B) for an additional 10,900 hit points, an improvement to her mid- and short-range AA bubbles and for faster rudder shift. Research of Hull (B) 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 a top priority; it brings additional hit points and a large bump to Iowa’s anti-aircraft capabilities. The Propulsion module upgrade should come next, with the Fire Control System upgrade saved for last.

Melhor Configuração

Atualizações

The recommended upgrades for Iowa are as follows:

• Slot 1: This slot is most commonly filled with Predefinição:Main Armaments Modification 1, though Predefinição:Auxiliary Armaments Modification 1 is a popular pick for captains who go for a full AA build with other upgrades and commander skills.
• Slot 2: There's really only one choice here for battleships - Predefinição:Damage Control System Modification 1. This will reduce chances of fire and flood.
• Slot 3: There are a few options available. Predefinição:AA Guns Modification 1 will boost her AA strength, while Predefinição:Secondary Battery Modification 1 will boost the range and accuracy of secondaries instead. Predefinição:Artillery Plotting Room Modification 1 will increase range and give secondaries a slight boost in range and accuracy, but is likely a weaker choice than the other two.
• Slot 4: Predefinição:Steering Gears Modification 1 is recommended and will reduce rudder shift time. Captains with fire problems could also consider Predefinição:Damage Control System Modification 2, reducing the amount of time on fire and conserving hit points.
• Slot 5: Maximizing stealth is never a bad choice. With the Concealment Expert commander skill, Predefinição:Concealment System Modification 1, and appropriate camouflage, this ship can choose when to engage the enemy.
• Slot 6: The recommended choice is Predefinição:Artillery Plotting Room Modification 2 to give the main battery better accuracy; installing this upgrade will make her guns exceptionally accurate at ranges of ~12-13 kilometers, much more so than contemporaries. Predefinição:Main Battery Modification 3 will improve damage-per-minute, and may surprise a cruiser who still expects the battleship to be reloading.

Consumíveis

Iowa equips the following consumables:

• Slot 1: Damage Control Party 
• Slot 2: Repair Party 
• Slot 3: Spotting Aircraft  or Caça 

Camuflagem

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.

Sinais

Iowa’s signal loadout should focus on two objectives: maximizing her experience earnings and maximizing her survivability. Equal Speed Charlie London (), Hydra (), and Red Dragon () will help with the former, while India Delta (), India Yankee (), and Juliet Yankee Bissotwo () will help with the latter. Sierra Mike () is worthy of consideration for captains who enjoy flexing Iowa’s speed, while November Foxtrot () and November Echo Setteseven () will help reduce her consumable cooldowns and further enhance her AA suite.

History

Design

The Iowa-class battleships were designed in 1938 when the Navy proposed a new class of battleships that were to develop on the lessons learned from the development and construction of the North Carolina-class and South Dakota-class of battleships. Of exceptional concern were the Kongo-class battleships that are able to use speed to harass convoys and outgun fast aircraft carrier escorts, as well as the refusal of Japan to disclose details regarding the construction of the Yamato-class battleships. Wishing to have an apt and equal response, the construction of the Iowa-class was approved. These factors culminated in the US, Britain, and France invoking the "Escalator Clause" of the second naval treaty, which permitted 16 inch guns and 45,000 long tons standard displacement.

With the emergence of aircraft carriers and the need to protect them from surface threats, the concept of “fast battleships” came into prominence; ships designed with the speed and the endurance to keep pace with carrier groups and serve as a major deterrent to surface attack. To fulfill this role, the design called for a top speed of 33 knots from 8 boilers connected to 4 turbines; each turbine to a propeller shaft. This layout produced a total of 230,000 shaft horsepower. Furthermore, the ship had a greater waterline length-to-beam ratio, making the ship longer than its predecessors, as well as notably faster.

The main armament of the Iowa class — while using rifles of the same diameter of 406mm as preceding ships — were longer than the rifles on the South Dakota-class (increased from 45 calibers to 50 calibers) and therefore have the distinction of being the largest rifles mounted on any US warship to date. This increase in rifle length resulted in greater distance for expanding gases in the chamber to propel the projectile, which equated to higher muzzle velocity, greater range, and greater armor-penetration capabilities than preceding rifles. Furthermore, the Iowa-class had a comprehensive suite of secondary and anti-aircraft guns due to the design emphasis of increased protection against air attacks; the armament systems were supplemented with state-of-the-art radar-based fire control systems (Iowa had Mark 8 Fire Control Radar sets fixed upon Mark 38 Fire directors).

The Iowa-class battleships had the characteristic “all-or-nothing” armor scheme seen in preceding American battleships, with the thickest armor around the citadel between Turrets A and Turret C. The outer hull plate was 38mm Special Treatment Steel (STS) and the side armor of 307mm was angled at 19-degrees inwards in order to confer greater armor thickness for little additional weight; this was especially advantageous against shells at longer range. The weather deck was 38mm STS, the main armor deck was 152mm STS/Class B, and the splinter deck was 25mm over the magazines and 16mm over machinery spaces. The hull has a triple bottom under the citadel to protect against underbottom explosions. The armor scheme of the Iowa-class was largely the same as the preceding South Dakota-class, which offered protection from 406mm/45 rifles firing 1,016 kg Mark 5 shells from ranges between 16,000 - 27,000 meters.

From the onset, Iowa was designed to fulfill the role of a fleet flagship; therefore, the conning tower was more enlarged than those of her sisters, to accommodate an admiral on board. Iowa was, therefore, the ideal choice when selecting which ship should ferry President Franklin D. Roosevelt to the Tehran Conference of 1943.

USS Iowa was the lead ship of the Iowa-class battleships. Ordered at the Brooklyn Navy Yard in New York City, she was laid down on 27 June 1940, launched on 27 August 1942, and commissioned into service on 22 February 1943.

Service

The Iowa-class battleships were a class of fast battleships ordered by the United States Navy in 1939 and 1940 to escort the Fast Carrier Task Forces that would operate in the Pacific Theater of World War II. Four were completed; two more were laid down but canceled at war's end and scrapped. Like other third-generation American battleships, the Iowa class followed the design pattern set forth in the preceding North Carolina-class and South Dakota-class battleships, which emphasized speed and the secondary and anti-aircraft batteries.

In-game historical inaccuracies

• The Measure 32/22D permanent camouflage was worn by Missouri. Iowa's camouflage was Measure 32/1B.
• Measure 22 camouflage is also missing. Iowa wore this scheme in 1943 and 1945. Only Missouri has it.
• Three 20 mm Oerlikon cannons fitted to 'B' turret are missing.
• The outer hull strake abreast of the main armor belt should be 38mm rather than the in-game 25mm. Interestingly, Missouri in-game has the proper thickness.
• The 5"/38 caliber gun's actual rate of fire is 15 rounds per minute; Iowa's is 10 rounds per minute. Only Massachusetts has the correct rate of fire.
