Ishizuchi — Japanese premium Tier IV battleship.

One of the draft designs for a battlecruiser of the Imperial Japanese Navy that subsequently materialized as the Kongo class. The ship had a high speed and an impressive artillery. The arrangement of main turrets allowed her to fire a full broadside with all main battery guns. The known drawback of the ship's design was a very weak horizontal armor.

Player Opinion

Performance

Ishizuchi, while marketed as a Tier IV battleship, might properly be called a battlecruiser. She features quite good maneuverability and speed for a battleship, but her armor simply cannot take the punishment of her contemporaries like Kaiser or Wyoming. At first glance, she heavily resembles the Tier V Kongo, which is largely correct: Ishizuchi is essentially a Kongo prototype. She looks a lot like her Tier V cousin, but that's where the similarities end. Ishizuchi has a bearable rudder shift time of less than 13 seconds and a top speed bordering 28 knots, making her one of the faster battleships in the game. She also features five (5) twin-gun turrets containing decent 305mm guns. Unfortunately, she suffers from absolutely terrible anti-aircraft defenses and almost no armor, meaning she must be careful and look at the map often for torpedo bombers and enemy battleships.

Her 305mm armor-piercing rounds will also give players some headaches. Don't expect them to reliably penetrate enemy battleships; hilariously, she is better off firing high explosive rounds at enemy battlewagons. With a 32% base fire chance out of her HE shells, she can reliably light enemy battleships on fire and keep them burning for extended periods of time. Thankfully, her AP rounds are perfectly serviceable against enemy cruisers, due to a low chance of overpenatrating the citadel.

Pros:

• Great maneuverability for a battleship.
• Good health pool for her tier at nearly 50,000 hit points.
• Best-in-tier reload time of 25 seconds on her main battery.
• Excellent HE shell performance for her tier.
• Better-than-average turret traverse for IJN battleships
• Range is good for a battleship of her tier at 15.3 km
• Lots of secondary guns; destroyers trying to close with her will get a nasty surprise. Unusual for a battleship, her excellent HE performance and heavy secondary battery make her an effective destroyer hunter.
• 305mm guns deadly to cruisers.

Cons:

• Terrible anti-aircraft suite.
• Paper-thin armor; most battleships and some cruisers can penetrate her main armor belt.
• 305mm AP shells are defective historically, and shatter on practically everything.
• High surface-detection of over 15 km.
• Abysmal Anti-torpedo protection.
• Easily citadeled between the #3 and #4 turrets due to a raised citadel.

Optimal Configuration

Upgrades

The recommended upgrades for Ishizuchi are as follows:

• Slot 1: Main Armaments Modification 1 *
• Slot 2: Damage Control System Modification 1 

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 armament should choose Auxiliary Armaments Modification 1 .

Commander Skills

The following information is provided for players who wish to create a permanent captain for the ship. Those players who are retraining captains or using the ship to gain extra experience for a captain should consult the page relevant to the ship to which the captain will be assigned. Be aware that Manual Fire Control for Secondary Armament does not provide the accuracy bonus it does to ships of tier 7 and up; it may be better to not have it.

Historical Info

The Ishizuchi (石鎚, named after Mount Ishizuchi) is based off of Vickers Design 472 which is the originally accepted design for the Kongo-class of battlecruisers. After the rejection of B-39, B-40, and B-41 designs, Sir George Thurston redesigned the draft in 1911 in order to create Design 472 (known to the Japanese as B-46). This design was accepted and was laid down on January 11, 1911 in Barrow-in-Furness, Britain. The original design called for ten 305mm/45 guns mounted in five twin turrets, however, after being urged by Commander Kato Hirohasu and witnessing gun trials, the Japanese Navy made the decision on November 29, 1911 to alter the design to fit eight of the new 360mm/45 gun in four double turrets. These alterations were completed successfully and the ship was launched on May 18, 1912, and was christened Kongo.

The name "Ishizuchi" was given to the design by Wargaming in accordance with the Imperial Japanese tradition to name battlecruisers after mountains.
