Like ''Mutsuki'', it features 2 torpedo launchers of 3 torpedo tubes each, but it also features a worse detection range (can be spotted nearly 1km further away), is slower again, and has a longer rudder shift time. While the stock torpedoes hit hard, ''Hatsuharu'' really comes into its own once you get the upgraded torpedoes. Featuring significant speed over the stock torpedoes, the upgraded torpedoes give the enemy ship less time to react and dodge, resulting in more hits (in comparison to stock). It can still drop torpedoes undetected; however, captains must be careful when facing other destroyers as they can possibly detect you before you detect them. | |
? | + | Moreover, ''Hatsuharu''’s guns are a significant improvement over her predecessors. With two (comparatively) faster-turning dual high-velocity 12.7cm, ''Hatsuharu''’s shells hit harder, are more accurate, fly faster, and follow a much flatter trajectory than ''Mutsuki'' and ''Minekaze''’s low-velocity 12cm. While American destroyers continue to hold the lead in raw rate of fire, Japanese destroyer players can — for the first time — fight off overeager ''[[Sims]]'' and ''[[Mahan]]'' captains with the guns on ''Hatsuharu''. Japanese destroyer guns from ''Hatsuharu'' through ''[[Kagero]]'' have significantly better shell velocity and arc. Engage American destroyers at medium range (8km - 10km) to maximize ''Hatsuharu''’s advantages and mitigate her weaknesses in a gunfight. | ||

? | The Hatsuharu-class (初春) destroyers were designed to accompany the Japanese main striking force and to conduct both day and night torpedo attacks against the United States Navy as it advanced across the Pacific Ocean, according to Japan's naval strategic projections. They were to be armed much as the Fubuki-class despite displacing only 1400 tons compared to the 1700 tons of the earlier destroyers. Furthermore their fire control systems were to be more modern than the older systems and suitable for anti-aircraft use. This required the gun turrets to be modified for high-angle fire, which also meant more powerful motors to traverse and elevate the guns more quickly to engage high-speed aircraft. The torpedo launchers were to be given a protective shield to allow for use in heavy weather and to protect against splinter damage. And the Hatsuharu vessels were to be fitted with modern, enclosed command spaces protected against strafing aircraft. These requirements could only be met by adding weight high up on the ship and increased the ship's center of gravity. The only way to adhere to the allotted displacement was to try to reduce the weight of the hull and other equipment below the waterline as much as possible. But this put the ship's designers in a no-win situation as any reduction of weight below the waterline further raised the ship's center of gravity and reduced her stability. | + | The ''Hatsuharu''-class (初春) destroyers were designed to accompany the Japanese main striking force and to conduct both day and night torpedo attacks against the United States Navy as it advanced across the Pacific Ocean, according to Japan's naval strategic projections.

? | The weight of the hull could generally be reduced by using higher grades of steel that were lighter and smaller for the same strength, reducing dimensions, particularly length, or using advanced construction techniques like welding that saved weight over the conventional riveting. The Japanese used the same high tensile steel for the Hatsuharu class as they did for the older destroyers and chose not to increase the power of the turbines and boilers to achieve the desired high speed, but lengthened the hull to offset the reduced power of the light-weight machinery. The beam was increased to counter some of the extra top-weight, but the draft was reduced to reduce hull resistance, which also reduced stability by lessening the area of the hull beneath the waterline in comparison to the area above it, which was subject to pressure from the wind. Electric welding was extensively used to reduce weight although it was at an early stage of development in Japan and was still problematic. | + | The weight of the hull could generally be reduced by using higher grades of steel that were lighter and smaller for the same strength, reducing dimensions, particularly length, or using advanced construction techniques like welding that saved weight over the conventional riveting.

The Hatsuharu-class ships were shorter than their predecessors, at 109.5 m (359 ft 3 in) overall. The ships had a beam of 10 metres and at full load a draft of 3.35 m (11 ft 0 in). Despite the emphasis on weight-saving during construction, the ships were significantly overweight as completed and displaced 1,530 metric tons (1,510 long tons) at standard load, and 1,981 metric tons (1,950 long tons) at full load, nearly 130 metric tons (100 long tons) more than planned. | The Hatsuharu-class ships were shorter than their predecessors, at 109.5 m (359 ft 3 in) overall.

Both funnels were inclined to the rear to reduce the amount of smoke that might reach the bridge. A tripod mast was fitted between the bridge and the fore funnel. Between the two funnels was the forward 61 centimeters (24 in) triple torpedo tube mount fitted on a low platform. Behind it "was a torpedo locker with its mechanical quick reload system (Kiryoku sōtenshiki jihatsu sōten sochi) for the three reserve torpedoes inside."[7] To preserve lateral stability the aft funnel was offset to starboard while the torpedo mount was offset to port. The reload locker was also offset slightly to port and angled inboard to facilitate reloading. The middle torpedo mount was positioned behind the aft funnel on the center line, but its reload locker was positioned identically to that of the forward mount. Superimposed to starboard and overlapping the middle mount was the rear triple torpedo mount positioned on the rear deckhouse. Immediately behind the mount was its locker positioned on the center line, but angled slightly to the right so that its mount only had to traverse slightly to align with the locker and begin reloading. This was the first ship in history to be fitted with superimposed torpedo tubes, made necessary by the designer's insistence on fitting nine torpedo tubes despite the Navy's requirement for only six. | |
A small platform that carried a 2 m (6 ft 7 in) rangefinder was mounted above the rear torpedo locker and a 90 cm (2 ft 11 in) searchlight was mounted on a tower behind the rear funnel. The two license-built Vickers 40 mm (1.6 in) (pom pom) anti-aircraft guns were mounted on an elevated platform at the front of the rear funnel. Curiously they were another case where the designer exceeded the requirements laid down by the Navy. | A small platform that carried a 2 m (6 ft 7 in) rangefinder was mounted above the rear torpedo locker and a 90 cm (2 ft 11 in) searchlight was mounted on a tower behind the rear funnel.

Performance
After the fantastic Minekaze and Mutsuki destroyers, at first Hatsuharu might feel like a bit of a let-down. Like Mutsuki, it features 2 torpedo launchers of 3 torpedo tubes each, but it also features a worse detection range (can be spotted nearly 1km further away), is slower again, and has a longer rudder shift time. While the stock torpedoes hit hard, Hatsuharu really comes into its own once you get the upgraded torpedoes. Featuring significant speed over the stock torpedoes, the upgraded torpedoes give the enemy ship less time to react and dodge, resulting in more hits (in comparison to stock). It can still drop torpedoes undetected; however, captains must be careful when facing other destroyers as they can possibly detect you before you detect them.
Moreover, Hatsuharu’s guns are a significant improvement over her predecessors. With two (comparatively) faster-turning dual high-velocity 12.7cm, Hatsuharu’s shells hit harder, are more accurate, fly faster, and follow a much flatter trajectory than Mutsuki and Minekaze’s low-velocity 12cm. While American destroyers continue to hold the lead in raw rate of fire, Japanese destroyer players can — for the first time — fight off overeager Sims and Mahan captains with the guns on Hatsuharu. Japanese destroyer guns from Hatsuharu through Kagero have significantly better shell velocity and arc. Engage American destroyers at medium range (8km - 10km) to maximize Hatsuharu’s advantages and mitigate her weaknesses in a gunfight.Pros:
- Improved guns gain significantly increased accuracy, range, traverse speed, and power.
- Relatively low detection range (in comparison to most ships).
- Devastating torpedo damage for its tier (3 torpedo hits can cripple an equal tier battleship).
- Decent torpedo speed makes it harder to dodge.
- Has access to the Torpedo Reload Booster consumable which reduces torpedo reload by half when used and delivers rather good torpedo rate of fire.
- Good torpedo launch arc, doesn't need to turn much to launch torpedoes.
Cons:
- Longer detection range than most destroyers means you get spotted easier.
- Cruiser-like top speed.
- Turret traverse and rate of fire remain inferior to American destroyer guns.
- Poor armor indicative of Japanese destroyers.
Research
Like with all Japanese destroyers, the torpedoes are the primary armament followed by the guns as secondary. It is recommended that captains first focus on getting the upgraded torpedoes in order to maximize their hit chances. While it does sacrifice rate of fire a little bit, and removes 1 gun (as you must get the hull upgrade), as stated earlier the increased torpedo speed is worth it.
While the gun range upgrade is nice, captains can save themselves 6000 experience towards Fubuki if you decide to pass up the 0.9 increase in gun range.Optimal Configuration

Camouflage
Type 1, 2, or 5 camouflage can be equipped for credits; Types 1 or 5 are recommended at a minimum to reduce detectibility range.
Players who wish to spend doubloons can equip Hatsuharu with Type 17 camouflage that lowers her detection radius, reduces the accuracy of incoming shells, and increases the amount of experience she earns.
