Description
The Kongo-class, IJN Haruna, 1945 (榛名, namesake: Mount Haruna) is a gift rank V Japanese battleship with a battle rating of 7.0 (AB/RB/SB). It was introduced during Update "Danger Zone" as a reward for the 2022 Summer Quest event.
Haruna is the fourth and last of the Kongō-class battlecruiser (later fast-battleship), being commissioned in 1915 on the same day as her sister ship, Kirishima.
Seeing almost every major naval action in the Pacific conflict, she sailed with the southern fleet in prepration of the battle of Singapore, covered the Japanese landings in Malaya and Dutch East Indies, engaged in the battle of Midway and fought in the Guadalcanal Campaign. From 1943 onward she would primarily move between bases as escort and cover for withdrawals and transfers.
She would sink in the port of Kure Naval Base after several days of bombarding by Task Force 38 on 28 July 1945.
General info
Survivability and armour
At the first glance, the Haruna's protection is similar to that of her sister ship Kongo. Being originally commissioned as a battlecruiser, the Haruna's armour is quite underwhelming for a capital ship, thought still offers reasonable protection against cruiser. However, the devil hides within the details, as the Haruna has a different crew distribution compared to the Kongo, with roughtly 80% of her crew being located in the midship section, and 40% of them were positioned inside a vulnerable deck of the ship. This resulted into her being more vulnerable to concentrated fire from enemy ship, including cruisers that can chip a significant portion of the crew away if not taken care of soon enough.
Due to the placement of her third turret close to the vulnerable deck, it has a risk of catching fire from repeated HE salvos which can spread down into the shell elevater, potentially results in lethal detonation.
The Haruna will be able to pump out water if the flood control timer stays under 40 seconds. If you reach that threshold, staying afloat will be increasingly difficult.
Mobility
The Kongo-class's nature as a battlecruiser reflects in Haruna's speed, which is a very good 56 km/h. As a FBB this is only slightly less than most cruisers, and is leaps and bounds ahead of the speed of dreadnoughts. However, her acceleration and deceleration are still unexceptional, and her turning is not very good.

Armament
Primary armament
The 36 cm/45 Type 41, also seen on IJN Hyuga, is an exceptional 14-inch battleship cannon. Compared to the Hyuga, the IJN Haruna gets only 8 guns, but she features a new selection of shells. Her stock shell, Ordinary SAP, is identical to the shell on Hyuga, and certainly gets the job done. With the equivalent of 68.64 kg of TNT, her SAP is still a head and shoulders over even the HE on most other battleships. These shells will smash cruisers whenever they hit, and against battleships, while they will rarely penetrate the hull armor, the splash damage from the detonation will frequently destroy guns and turrets. Type 91 APC is an improvement over the Hyuga's equivalent AP shell, with extra penetration. This shell is mostly used against battleships, where the extra penetration is needed to penetrate the belt armor. The last shell is Type 0 Common, an HE shell. This shell is very poor, possessing only half the explosive filler of SAP. It may find some utility when it comes to sniping patrol boats or stray floatplanes, but overall, it isn't very good.

Secondary armament
The Haruna's secondaries consist of eight 15 cm/50 Type 41 cannons, four per side. Comparable guns can be found on the IJN Agano, although these guns can maintain a sustained rate of fire of 10 RPM. While they are 6-inch secondaries, they are nothing to write home about, as the best shell only has 81 mm of penetration at point blank range. The exceptionally high explosive mass of the SAP round - nearly as good as HE - makes it very well suited for fighting destroyers.

Anti-aircraft armament
Being in a late war refit, the Haruna is outfitted with a ludicuous number of anti-air guns consists of twelve 127 mm flak cannons and exactly one hundred of 25 mm Type 96 autocannons on board the ship. The sheer number number of guns alone allows the Haruna to fend off any aircraft within 3 km range, though due to the 25 mm gun's short effective range, they can be mostly outranged by a high-flying bombers.
Due to the 127 mm were classified as an AA armaments, they were only loaded with an HE-TF shell, this would somewhat reduce the auxillary firepower against smaller vessels.
In addition, the numerous gun mounts of the Haruna can also be detrimental to Haruna's survival, as they can be easily destroyed and/or caught fire from any HE blasts near it, draining a significant portion of her crew in the process. Because of this, it is recommended not to repair them while under enemy fire.
Scout plane
Located between the aft main turrets is a deck area and catapult for one Aichi E13A1 scout plane which provides unique offensive and defensive abilities, expanding tactical options. Ship-launched scout planes fly just like regular tree units but lack munition choices and cockpit views. The E13A1 is equipped with a 7.7 mm Type 97 defensive machine gun and a formidable load of 4 x 60 kg bombs. It also has the scout plane ability to cap zones and lay down smoke cover (up to 3 times). Captains will be wise to remember to utilize the aircraft and consider when best to use it, for example to cap a point early or late in the match, to create a smoke screen to stymie enemy bombardment and repair, to attack enemy units directly, or perhaps something completely new! Carrying a heavier bomb load than most other scout planes, this unit has a very good chance to sink enemy boats or even a destroyer.
Usage in battles
As with the other capital ship, the Haruna performs quite well at longer ranges against enemy cruisers and battleship. Though because of her lacklustre armour and secondary armaments, she does not fare well at a close range, where her weakness can be easily exploited.
Being a battlecruiser by origin, the Haruna enjoys a mobility advantage over the slower classic dreadnoughts that she will usually face at her BR. As Haruna's armour is not thick enough to withstand a direct hit from large calibre guns, it is recommended to either find a suitable cover to shield off the enemy fire or to "hit-and-run" by keep your distance from the enemy while also angle the ship to increase their effectiveness. Be wary however, as the Haruna's bulkhead is fairly weak, so some unlucky shell might went through and cause fatal damage. If you find that the enemies were concentrating fire at you, make sure to disengage them at the right moment to keep the Haruna stay aflot for a bit longer.
Pros and cons
Pros:
- Exceptional 14" guns with a very potent SAP round and comfortable gun arcs
- Very fast for her size
- Good AA protection
- Workable armour above waterline; turtleback around the magazines
- Access to floatplanes
Cons:
- Crew is more concentrated around the midship section compared to the sister ship, thus making them vulnerable to concentrated fire
- Extremely weak underwater protection, vulnerable to large calibre diving shots from heavy cruisers or above
- Third turret ammo rack can be detonated in a prolonged fire
- Subject to flooding and capsizing in addition due to aforementioned weakness
- Somewhat lacking in secondary firepower, thus making her vulnerable in a close-quarter combat against cruisers
- 127 mm batteries are categorized into AAA group and hence no combined manual control or ammo options
History
Devblog
The battlecruiser Haruna of the Kongō class was laid down in 1912 and commissioned in 1915. During the First World War, she did not see active combat. Before the start of World War II, the ship went through two modernization programs, during which Haruna was reclassified as a fast battleship, the combat potential of the ship was significantly increased and it became possible to use it to escort Japanese aircraft carriers. During the invasion of mainland China in 1937, the battleship Haruna was used to transport troops. The battleship fought the first battle of World War II in December 1941 in the Battle of Kuantan against the Royal Navy. She then was active in the area of the Malay Archipelago in operations to invade Borneo and the Dutch East Indies, going on to participate in the attack on Ceylon. In May 1942, after serving in dock, she joined the carrier group in the Battle of Midway, after which the ship took part in the Battle of Guadalcanal. During all the time of intense fighting, Haruna did not receive any significant damage. In October 1943, the battleship was sent to defend Wake Island from American attacks. In the Battle of the Philippine Sea, Haruna received two hits with armor-piercing bombs, repairs lasted until the autumn of 1944. After the Battle of Leyte Gulf, the battleship was damaged when running aground on a coral reef. While docking at the naval arsenal in Kure in July 1945, the ship participated in the defense of the base, but as a result of air raids, Haruna received several hits from American bombers in a few days and sank.
