''Izumo'' (出雲 "Outward Cloud" named for the Izumo province) in game was the A-140-J2, one of the alternate design proposals in the project that would result in the famous ''[[Yamato]]''-class. In 1936, after Japan had left the League of Nations and renounced the Washington Naval Treaty, the Imperial Japanese Navy contacted leading naval engineer Yuzuru Hiraga to design a new battleship not bound by treaty limits. Hiraga drew experience from designing the ''[[Yubari]]'', ''[[Fubuki]]'', and ''[[Mogami]]'' classes to help him design the new battleship, designated A-140. In all, 24 preliminary designs were submitted to Naval Command for review, with varying turret configurations and endurance. The A-140-J series designs were notable in that they were the only ones to mount 41 cm guns, as opposed to the "Type 94" guns that were in reality 46 cm caliber; the design of these ships were more mindful of the existing docks and slipways in Japan at the time. The A-140-J2 has a turret configuration similar to the HMS ''Nelson'' and had a hybrid engine concept. However, due to advancements in fire-control methods and the failures of hybrid-engines in the submarine tender ''Taigei'' and the seaplane tender ''Mizuho'', the plans were scrapped in favor of Hiraga’s 18-inch armed conventional layout, which would later become ''Yamato''. | ''Izumo'' (出雲 "Outward Cloud" named for the Izumo province) in game was the A-140-J2, one of the alternate design proposals in the project that would result in the famous ''[[Yamato]]''-class.

+ | The design, known as A-140-J2, was never built and therefore never named; the in-game name was given to the ship by Wargaming in accordance with the Imperial Japanese tradition to name battleships after provinces of Japan. There have been two real ''Izumo''s: the IJN ''Izumo'' was an armored cruiser built at the end of the 19th century that served in the Imperial Japanese Navy until 1945 and the JS ''Izumo'' which is a helicopter destroyer currently in the service of the Japan Maritime Self-Defense Force. | |||

? | * | + | * Actual name is ''A-140-J2''. The real ''Izumo'' was an armored cruiser that was still in IJN service during World War II, serving until July 1945. As such it is extremely unlikely that ''A-140-J2'' would have also been named ''Izumo''. | |
? | * | + | * As ''A-140-J2'' was merely a preliminary design, both hull upgrades are fictitious WW2 refits. | |

+ | * The triple mount version of the 25 mm/60 Type 96 anti-aircraft gun entered service in 1941; ''A-140-J2'' was designed in 1935. | |||

Izumo — Japanese Tier IX battleship.
One of the draft designs for a "super battleship" concept, preceding the appearance of the Yamato-class battleships. This design featured heavy armor and a sufficiently high speed complemented by powerful main battery guns that were unconventionally placed in three turrets located at the ship's front end.

Player Opinion
Performance
Once considered by many to be among the worst Tier IX ships in the game, Izumo has seen a variety of improvements since the launch of World of Warships. While her stock hull still has mediocre secondaries, a weak anti-aircraft battery, and bad turning characteristics, the AP shell penetration of Hull (A) has been significantly improved, allowing her guns (at least) to remain competitive against the likes of Iowa and Friedrich der Große beyond 15km.
Additionally, the in-game text is somewhat misleading: Izumo’s armor is tricky to use; she is highly reliant on using her sharply-angled bow to deflect AP shells fired at the hull. Once Hull (B) is unlocked, she goes from "bad" to "workable", with somewhat better secondaries and AA. However, she remains vulnerable to full penetration damage from high explosive shells (due to her large size and thin 32mm deck armor) and the fully upgraded AA suite is not adequate enough to fend off air attacks, even with support from allies. Pointing her bow at enemies and reversing at mid range — similar to how many captains play Dunkerque, Iowa, and North Carolina — is a valid tactic in Izumo, and is quite effective against enemy AP rounds. Like all high tier battleships, she remains vulnerable to fire.Pros:
- Good range on secondary battery.
- Accurate and good main battery, with very high shell velocity for a battleship.
- Decent hull armor along the front half of the ship.
- Good belt armor.
- Small superstructure means that incoming shells don't have a whole lot to hit (although the rest of the ship remains an vulnerable to penetrations by 203mm high explosive shells).
- Great angling potential.
Cons:
- Izumo is a large target (larger than Yamato!).
- Slowest Tier IX battleship.
- Worst concealment in the game; even Midway and Großer Kurfürst are stealthier by more than a kilometer.
- Large sections of armor ineffective against Tier VII-X battleships at any range (especially if showing an enemy the flat broadside of the ship).
- Turret placement leaves ship extremely vulnerable to attacks in aft arc and makes the number 3 turret very difficult to use.
- Very weak stern.
- Secondaries only fire to the side and rear, making them nearly useless in the typical play style of the ship.
- Weakest overall armor scheme of Tier IX battleships; Izumo is vulnerable to regular penetrations by high explosive rounds from most opposing heavy cruisers she will face.
Research
Optimal Configuration
Upgrades
The recommended upgrades for Izumo are as follows:
- Slot 1: Main Armaments Modification 1 *
- Slot 2: Damage Control System Modification 1
- Slot 3: Aiming Systems Modification 1 *
- Slot 4: Damage Control System Modification 2
- Slot 5: Concealment System Modification 1
- Slot 6: Main Battery Modification 3 *
Slot 1 provides players with the first option in choosing a desired role. Typically, Main Armaments Modification 1 is recommended to provide additional survivability to the main battery, but players who desire to specialize in the secondary or anti-aircraft armament should choose Auxiliary Armaments Modification 1 .
Slot 3 allows for further specialization. Generally, Aiming Systems Modification 1 is recommended because it reduces shell dispersion of the main and secondary armaments. To increase the effectiveness of the anti-aircraft armament, mount AA Guns Modification 2 (). Players wishing to specialize for secondaries should mount Secondary Battery Modification 1 ().
Slot 6 gives players options to finalize their build. For gunnery, mount Main Battery Modification 3 to decrease the reload time of the main battery. Template:AA Guns Modification 3 should be mounted for AA duties to increase the DPS of AA guns. Players wishing to increase the effectiveness of the secondaries should mount Secondary Battery Modification 3 ().

Consumables
Players can equip the following consumables on Izumo: Damage Control Party, Repair Party, and a choice between Spotting Aircraft and Catapult Fighter. It is strongly recommended to take the Premium versions of Damage Control Party and Repair Party to maximize surviveability.
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 Izumo with Type 19 camouflage that lowers her detection radius, reduces the accuracy of incoming shells, reduces her repair costs, increases her credit earnings, and increases the amount of experience she earns.
Signals
As with all battleships, Izumo comes with 8 signal flag slots. The three most important flags are India Delta, Juliet Yankee Bissotwo and India Yankee; all of which will improve your surviveability. If the captain goes with the Secondary Build, the addition of Mike Yankee Soxisix will further improve the performance of Izumo’s secondaries.
