Hatsuharu — Japonska Tier VI Torpédoborec.

Hatsuharu was a high performance ship despite displacement limitations imposed by the London Naval Treaty of 1930. The ship boasted a comparatively good AA defense. The powerful main battery guns were placed in enclosed turret mounts and could deliver anti-aircraft fire.

As a part of the Japanese destroyer line re-organization and expansion in Update 0.5.15, Hatsuharu falls one tier to her new home at Tier VI. There have been a few minor tweaks to Hatsuharu with the change, but she is largely the same. As before, upgrading to Hull (B) increases her health and anti-aircraft battery, but costs her one of her main battery guns. She retains the same twin triple-tube launchers she had previously. Her detection radius remains 6.7 km, while she loses minor amounts of speed and maneuverability from her previous incarnation. Captains who believed that Hatsuharu was under-gunned in her previous slot at Tier VII will likely be more comfortable with her armament one tier lower.

On the other hand, new Japanese destroyer captains who are moving up to Hatsuharu from Minekaze will find their new acquisition to be something a mixed bag: her guns are a significant upgrade from those of Minekaze, while it can be argued that her torpedo armament is a downgrade. Not only is she less flexible with only two torpedo launchers, the reload time is very nearly double that of Minekaze; in exchange, Hatsuharu’s torpedoes can eventually be upgraded to longer-ranged with a bigger punch. Further complicating things is the fact that her torpedo upgrade is locked behind Hull (B), meaning captains must invest experience in the hull upgrade first before having the ability to upgrade her torpedoes.

Without her improved torpedoes, Hatsuharu is stuck with fish that have a paltry 6.0 km range. This forces Hatsuharu into more of a mid-tier American destroyer play style, requiring captains to utilize islands and smoke effectively to land successful torpedo strikes against enemy capital ships. Hatsuharu plays like a completely different ship once she has her upgraded torpedoes, however. The 10.0 km range of her Type 8 mod. 2 torpedoes is more than workable, and her guns can add notable contributions to her damage when used judiciously in the right situations.

Hatsuharu comes off as the inferior destroyer when compared side-by-side with Fubuki, but things flip back the other way one tier up when the same comparison is made between the successors of both ships (Akatsuki and Shiratsuyu). Captains frustrated with Hatsuharu should remember that she is merely a stepping-stone to better things beyond.

Plusy:

• Improved guns gain significantly increased rate of fire, range, and shell arcs.
• Lowest detection range of Tier VI destroyers.
• Decent torpedo speed makes her torpedoes harder to dodge.
• Generous torpedo launch arcs.

Mínusy:

• Turret traverse and rate of fire remain inferior to American destroyer guns.
• Poor armor.
• Fewer torpedoes than Fubuki: only two triple-tube launchers compared to Fubuki’s three.
• Slower than predecessor Minekaze, with worse detection range to boot.

Výzkum

Like the other Tier VI Japanese destroyer, Fubuki, Hatsuharu is painful to play until Hull (B) and the Torpedo upgrade module are unlocked and equipped. Those need to be top priority. Save the Fire Control System module for last, or skip it altogether and move on to Shiratsuyu.

Doporučená konfigurace

Vylepšení

The recommended upgrades for Hatsuharu are as follows:

• Slot 1: Úprava hlavní výzbroje 1 ()
• Slot 2: Úprava pohonu 1 ()
• Slot 3: Úprava zaměřovacích systémů 1 () or Úprava hlavní baterie 2 ()
• Slot 4: Úprava pohonu 1 ()

Mid-tier destroyers like Hatsuharu don't have many outstanding options for upgrades. Main Armaments Modification 1 is the best pick for Slot 1, while Propulsion Modification 1 is recommended in Slot 2. Propulsion Modification 2 is the best pick of a sorry lot for Slot 4. Slot 3 offers either Aiming Systems Modification 1 or Main Battery Modification 2; either provides a minor boost to Hatsuharu’s main battery.

Spotřební doplňky

Hatsuharu can equip the following consumables:

• Slot 1: Havarijní tým ()
• Slot 2: Kouřový generátor()
• Slot 3: Posílení motoru

All destroyers should invest credits (or doubloons) in Havarijní tým II (). Šablona:Engine Boost II probably isn't worth it — Hatsuharu’s speed isn't amazing, but it's not awful either — while Kouřový generátor II () likely is, especially if her commander does not have the Concealment Expert skill.

Kamufláž

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 16 camouflage that lowers her detection radius, reduces the accuracy of incoming shells, and increases the amount of experience she earns.

History

Design

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 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.

Extensive weight-saving measures were used during the design and construction of the hull. More frames of lighter construction were spaced more closely together to reduce the thickness of the hull plating and the extensive use of welding (only the longitudinal strength members and a few other parts were riveted) were some of the techniques utilized to reduce hull weight by 66.5 tonnes (65.4 long tons; 73.3 short tons) in comparison to the Fubuki class. The Hatsuharu vessels were some 10 meters (32 ft 10 in) shorter than the Fubuki-class vessels, but weighed 4.9 tonnes (4.8 long tons; 5.4 short tons) per 1 meter (3.3 ft) of hull length compared to the latter's 5.09 tonnes (5.01 long tons; 5.61 short tons) per 1 meter (3.3 ft).

The Hatsuharu-class ships were shorter than their predecessors, at 109.5m (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 hull of the Hatsuharu-class vessels retained the general configuration of the Fubuki-class destroyers with a long forecastle and a pronounced flare of the forecastle to improve sea-keeping at high speeds by adding buoyancy and reducing the spray and water coming over the deck. A large bridge structure was located at the aft end of the forecastle deck topped by four fire control stations of various types. Lowest, just above the compass bridge, was the torpedo director (Hassha shikisho), with the gunnery fire direction station (Shageki shikisho) next above. The fire director tower (Hōiban shagekito) was third from the bottom and behind it was the 3m (9 ft 10 in) rangefinder. Each of these was protected by 10mm (0.39 in) plates of Dücol steel against strafing and shell splinters.

For the first time in a Japanese destroyer a superfiring turret was fitted forward of the bridge. It was only a single gun Model A turret, to save weight high in the ship, and was mounted on a deckhouse to elevate it above the twin gun Model B Mod 2 (B-gata kai-2) turret mounted on the forecastle deck. The second twin gun turret was mounted at the rear of the ship on the main deck. These turrets were slightly heavier than the earlier Model A and Model B turrets fitted on the Fubuki’s. All turrets were fitted with the 127mm (5.0 in) Type 3 gun.

The uptakes of the two forward boiler rooms were trunked together aft of the break in the forecastle into the fore funnel while the rear boiler room exhausted into the smaller rear funnel. 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." 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 2m (6 ft 7 in) rangefinder was mounted above the rear torpedo locker and a 90cm (2 ft 11 in) searchlight was mounted on a tower behind the rear funnel. The two license-built Vickers 40mm (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.
