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.

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. 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

Speedforward / back
AB66 / 29 km/h
RB57 / 25 km/h

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

Ammunition180 rounds
Vertical guidance-5° / 43°

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

8 х Turret15 cm/50 Type 41 cannon
Ammunition150 rounds

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.

Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).

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
  • 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.
