? | 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. With a “loosening” of the restrictions imposed by the Washington and London Naval Treaties of the 1920s and 30s, the designers were encouraged to improve the fundamental aspects of the new design: the propulsion, the armament, and the armor. Furthermore, with the onset of World War II, another threat emerged: the battleships of the Imperial Japanese Navy. Of exceptional concern was the construction of the ''[[Yamato]]''-class battleships. Wishing to have an apt and equal response, the construction of the ''Iowa''-class was approved. | + | 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.

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'' | + | 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 allowed for the use of greater powder charge, 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 | + | 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 side armor of 304mm was angled at 19-degrees inwards in order to confer greater armor thickness for no change in weight; this was especially advantageous against plunging shells. This arrangement guaranteed protection from shells fired from similar 406mm rifles from ranges between 16,000 - 27,000 meters. Most of the other parameters, such as torpedo bulkheads, were of similar design as seen in the ''South Dakota'' class. | |
? | From the onset, | + | 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==== | ====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. | 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.

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
Performance
The historical counterpart of the famed battleship Yamato, Iowa is the pinnacle of the various fast battleship designs the United States commissioned into service before and during World War II.
By using what you have learned in the North Carolina, Iowa becomes even more potent as it she is more nimble and sturdy at her tier albeit longer. However, Iowa’s citadel is very easy to hit when broadside, especially under the front turrets so careful positioning and good situational awareness is required at all times to ensure you don't get removed from the game with a devastating strike, and it makes fighting at close ranges very tricky as her length may be more of a liability than a total asset. However, once mastered, Iowa’s capabilities are unmatched by just about any battleship in game, combining speed, firepower, and survivability in a way that is nearly impossible to match in any other ship in her tier and below. The mobility allows you to get to where you are needed, the powerful superheavy rounds allow you to damage whatever you encounter there, and the armor allows you to tank punishment provided you don't show broadside or get blindsided by a torpedo wall.
LittleWhiteMouse's Ship Review: Iowa from the NA ForumsPros:
- 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 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%).
- The fastest battleship in the game at a whopping 33 knots.
- Third turret has a greatly improved gun arc over North Carolina, allowing it to be used while angling effectively.
Cons:
- Weaker broadside armor than standard Battleships, but stronger broadside armor than the NC.
- Sizable portion of the Citadel goes above the waterline and runs from forward turrets to aft.
- Bad rudder shift time (over 20 sec) until Hull (C).
- Longest ship so far (by a decent margin) with a turning circle to match in the American battleship line which can take some getting used to when trying to dodge torpedoes.
- Very tall superstructure makes her easier to hit, especially when trying to hide behind islands.
- Weak secondary armament, very low range on secondary armament as well compared to counterparts.

Camouflage
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.
