Special

Azuma — Japanese special premium Tier IX cruiser.

A powerful high-speed ship (Project B-65) designed to destroy American heavy cruisers and confront Alaska-class "large cruisers". Some design solutions were borrowed from Yamato-class battleships. She was armed with nine 310 mm guns and had good anti-torpedo protection.

Azuma was first released for sale worldwide on 1 April 2019.She was removed for purchase for Free XP with the release of Update 12.4, and is now available in the Armory for 228,000 Coal .

Tier IX Premium Japanese cruiser Azuma is in the same "large cruiser" category as her counterparts Alaska and Kronshtadt. Azuma is well suited for long range fights, featuring nine 310mm guns in a 3x3 layout that have high velocity, flat arcs, and strong performance from her high explosive rounds. The main battery performance is the primary strength of the ship.

Azuma’s 310mm guns are the longest-ranged of the large cruisers found at Tier IX, clocking in at a base range of 19.1km before Gun Fire Control System Modification 2 or Spotting Aircraft . Though they still lag behind Kronshtadt some, her shell velocities are noticeably better than Alaska, making her gunnery fairly comfortable to use all the way out to her maximum range. Befitting her Japanese origins, she has the best HE alpha damage and fire chance of all the 12-inch armed cruisers, though her AP shell damage lacks slightly to that of her peers. The penetration values of her armor-piercing shells run about 10-15% lower than Kronshtadt at all ranges, but are pretty comparable to Alaska along the same curve. Overall, her main battery performance is a nice middle ground between the large cruisers already in the game: better HE performance than the rest, and comparable AP performance (though she lacks Alaska’s improved auto-bounce angles).

It's a good thing Azuma has all that main battery range to play with: of the Tier IX large cruisers, Azuma is by far the least durable, featuring no plating thicker than 25mm other than her internal belt and deck armor. This means she is exceedingly vulnerable to high explosive rounds at nearly all ranges and angles — as well as being overmatched by all 380mm class or larger battleship guns — in addition to her citadel spaces extending above the waterline. Azuma also has a fairly mediocre anti-aircraft suite, with the majority of its strength concentrated in long-range flak bursts that a skilled carrier player will easily dodge. Azuma has decent mobility, with a top speed of 34 knots and average rudder shift and turning circle for her class of ships, and can reduce her concealment to 11.8km when fully built for it. Consumable wise, Azuma features standard cruiser consumables with the exception of her Repair Party , which has a reduced cooldown compared to the usual version.

These characteristics combine to make Azuma very one-dimensional to play. She is very good at farming damage at range, but her armor scheme and thin plating make her vulnerable at close quarters, forcing her into a long-range, kiting play style that has lower influence on the outcome of games. She is unable to approach close to key capture areas until late game situations where there are fewer ships to focus fire her, but given her armor scheme and detection radius, surviving into the late game will be a challenge for most captains.

Pros:

• Large health pool, though notably smaller than other super cruisers
• Reduced cooldown on her repair party, also starts with 1 extra charge
• Improved main gun accuracy compared to other super cruisers like Alaska
• Excellent HE firepower, high alpha strike damage that can penetrate 50mm of armor
• Powerful AP rounds, a good shot on a broadside cruiser can result in a devastating strike
• Long main gun range of 19.1km, surpassed only by Siegfried among Tier IX Cruisers
• Relatively low surface detection for a supercruiser, though still worse than other heavy and light cruisers

Cons:

• Vulnerable citadel placement, easy to hit if Azuma is broadside
• 60 second duration fires, similar to other supercruisers and battleships
• Main gun turrets are surprisingly fragile, gets knocked out often
• Slow turret traverse, more in-line with battleship turret rotation speeds
• Weak AA armament, reliant on allied AA cover or fighter support
• Azuma lacks any torpedo armament, unusual for a Japanese cruiser
• Very wide turning radius with slow rudder shift time, she has difficulty dodging enemy attacks

Research

As a premium ship, Azuma has no upgrade modules to research.

History

Design

The decisive victory over the Imperial Russian Navy at the Battle of Tsushima in the Russo-Japanese War of 1904-1905 was the catalyst of what became the Imperial Japanese Navy’s “Decisive Battle” doctrine. This strategy consisted of four primary components; a decisive surface fleet engagement with big guns, attrition tactics, quality over quantity, and nighttime torpedo attacks. When the Washington Naval Treaty was signed in 1922 limiting the size of Japan’s fleet to be greater than that of Italy and France, while lesser than that their more likely enemies of the United Kingdom and the United States, the emphasis of the Decisive Battle doctrine became all-encompassing in the Imperial Japanese Navy.

In 1936, the IJN formed the Night Battle Force. This force would attack the enemy’s outer defense ring of cruisers and destroyers at night to break through and launch torpedo attacks on the enemy’s battleships. What remained of the enemy fleet would be defeated by the IJN’s battle fleet the following day. To protect the Night Battle Force, a division of fast battleships or battlecruisers were assigned to the force. Initially the Kongo-class battlecruisers were chosen, and were modernized to fast battleships during the 1930s. The Japanese plans, however, intended to eventually replace the Kongo’s with four heavy and brand-new ‘super’ cruisers.

As originally envisioned in 1936, these ships — what would later become the B-64 and B-65 cruisers — would carry 12” guns, be protected by armor against 8” shells, and be capable of speeds up to 40 knots. These ships were designated as the “Super Type A” cruisers, and a total of six were planned to be ordered, two in the Circle Five Program production order set to begin in 1942, and the remaining four in the Circle Six Program production order that was abandoned in the early stages of planning due to the Japanese entry into World War II and shifting priorities. Ultimately, no ships of this type were ever ordered or laid down.

B-65’s hull was planned to be 240m long with a beam of 27.2m, with a designed draft of 8.8m. The planned maximum displacement was 34,800 metric tons. The planned machinery was to consist of eight Kampon boilers, which would produce steam for four turbines for a maximum output of 160,000 shp. This would allow B-65 to reach a maximum speed of 33 knots. With 4,545 tons of fuel oil on board the calculated cruising range was 8,000 nautical miles at 18 knots.

B-65’s main armament was planned with nine 310mm/50 guns, which were to be mounted in three triple turrets along the centerline, two forward, one aft. These guns were still undergoing development for the battlecruisers of both the B-64 and B-65 class, and could fire a 561kg heavy projectile at ranges up to 32.9km. Depending on the combat range the rate of fire could reach three rounds per minute and gun, while at higher elevations the reload times would be longer. The secondary armament was planned to consist of sixteen 100mm/65 guns, mounted in eight twin turrets with four on each side of the ship. Each gun was capable of firing a 13kg HE shell at sea targets 19.5km away, or at planes at an altitude of up to 13km. Unlike many other guns no other shells were provided. The rate of fire was usually around 15 rounds per minute and gun.

Anti-aircraft-armament did not differ from other ships, relying on four twin mounts with 25mm guns, and two 13.2mm twin machine guns. Unlike the heavy cruisers that preceded her, no torpedo armament was envisioned. A centerline mounted catapult would allow B-65 to carry up to three seaplanes.

B-65's armor was designed to be resilient against cruiser fire primarily, while also being strong enough to repel air attacks. The main belt was 190mm thick, and inclined at 20° to add further protection, which was supposed to protect against large caliber shells at ranges until 20km. The thickness was also used for the forward and rear bulkhead, while the deck armor and deck slopes were thinner at 125mm, which was deemed sufficient to resist an 800kg bomb and large caliber shells at ranges up to 30km. As protection against underwater explosions the torpedo defense system was designed to withstand an underwater explosion of 400kg.

Historical Inaccuracies

• Azuma is actually the name of an armored cruiser that was built in 1898 and fought in the Russo-Japanese War. No other ship in the Imperial Japanese Navy ever inherited the name.
• Azuma’s enhanced anti-aircraft suite in-game is envisioned in a late-war configuration that was not a part of her original design.
