Player Opinion

Performance

Yahagi is a Japanese light cruiser which sits at Tier V. She is very strong as she has one of the best HE shell performances and one of the best torpedo batteries for a ship of this type and tier. However, this ship does not sail without its quirks.

For starters, Yahagi is very poorly armored and has an extremely high unprotected citadel. If a player dares to turn broadside to any ship, regardless of class, they are almost guaranteed to citadel her when using AP. It is best for her to remain angled or just use her forward turrets and forget about the aft one. However this does have its flaws: the turrets are poorly armored and are prone to frequent incapacitations, if not being outright destroyed. In fact, just about every module is prone to frequent knockouts due to their poor armor, meaning it is absolutely compulsory to have Main Armaments Modification 1 , and even then they still have a chance to get knocked out.

Despite all these flaws, Yahagi does have a few good things that go in her favor. The first thing players will notice are three turrets with two guns each. Yahagi has one of the best fire chances out of any cruiser of this type and tier. One out of every four salvos of HE are almost guaranteed to start a fire, combined with the correct signals and commander skills, this makes her a floating flamethrower. However, as mentioned previously, the turrets are poorly armored and will frequently suffer incapacitations. In addition to this, Yahagi has a 9 second reload, which is an eternally long reload for a light cruiser. The AP shells too are lacking in combat performance, having low penetration and low damage, it is best to stick with HE if any meaningful damage wants to be done.

The torpedo battery is worth a separate mention. These torpedoes are extremely powerful and are almost guaranteed to take out same-tiered battleships with a single salvo. To add to that, they have an extremely long range for this tier and are also decently fast at 60 knots. However, these torpedoes have extremely bad firing arcs, requiring Yahagi to present a nearly complete flat broadside if a player wants to launch them.

Overall, Yahagi is an ok ship if played and used correctly. Take advantage of her torpedo's range and force any destroyers out of its smoke. Use her potent HE shell performance to wither ship's hitpoints away and use her torpedoes to cause flooding and massive damage in a short period of time.

Pros:

• Powerful HE shells with high damage and fire chance.
• Torpedoes have long range and high damage.
• AA suite is good for a tier V cruiser.
• Concealment is fairly good for a cruiser — the ship is theoretically capable of stealth torpedo launch.
• High top speed with fairly quick rudder shift.
• Speed boost consumable to help get out of trouble.

Cons:

• Very fragile; exposed citadel with little protection.
• Guns have a long reload, slow traverse, and poor ballistics.
• Accuracy is worse than 203mm armed Japanese cruisers, however this can be mitigated with the use of Aiming Systems Modification 1 .
• AP shell is virtually useless.
• Torpedoes tubes have terrible firing arcs.
• Torpedoes are fairly slow (60 kts) and easily spotted.
• While the rudder shift is fast, her turning circle is rather large.

CAPTION.

History

Yahagi (矢矧) was an Agano-class cruiser which served with the Imperial Japanese Navy (IJN) during World War II.

Design

Yahagi was the third member of the Agano-class light cruisers, which were designed after Japan formally abandoned the interwar naval treaties, and thus became limited in naval construction only by financial and industrial capacity. At this time, the series of ‘5,000-ton’ and ‘5,500-ton’ flotilla leaders (Tenryu through Sendai-classes) were seen as increasingly obsolete – the destroyers they were meant to lead were considerably faster, and the American destroyers they were meant to overpower were starting to look as though they could overpower the small cruisers. Their age and obsolescence necessitated their replacement starting in 1941. Starting in 1936, preliminary planning for the new cruisers dubbed the ‘Design No. C-39’ began. Basic requirements asked for a 5,000-ton, 36-knot cruiser capable of steaming 7,000 nm at 18 knots, with an armament of 2x3 15.5cm guns, 4x2 8cm and 3x2 25mm AA guns, and 2x4 61cm torpedo centerline mounts. At least one catapult and accompanying seaplane was required, as was protection of 100mm for the machinery spaces.

On 2 March 1938, the Navy Technical Department presented their incarnation of Design No. C-39. The design was significantly larger, and changed several elements. The main battery was to be situated in three twin mounts, the heavy AA guns cut in half, and the radius of action reduced by almost 1,000 nm. However, this was not satisfactory and the design was further modified. Finally, on 13 October 1939 the design was presented again, as Design No. C-41 – what would ultimately become the Agano-class.

As a ship designed in the wake of the Fourth Fleet Incident, the Agano-class was designed to have greater longitudinal hull strength than previous designs, with the result of almost the entire ship being constructed out of Ducol steel (a high-strength construction steel), except for the armored portions (which contributed to the strength of the hull), which was made out of CNC (Copper-Nichel-Chromium Steel). Overall, the hull was considered to be suitably strong and stable, something lacking in most Japanese interwar designs, and was a welcome change. The armor protection of the Agano-class followed the same philosophy as prior Japanese flotilla leaders – armored enough to resist the guns of American destroyers, and their potential flotilla leaders. The main armor belt protected the machinery spaces, and was 60mm thick. The space was closed off by 20mm transverse bulkheads, and the deck protection likewise was 20mm thick. The magazines had more narrow 55mm armor belts, and likewise shared 20mm bulkheads and armor decks. The gunhouses were armored with 25mm plates Ducol plates. Machinery was in five boiler rooms followed by three machinery rooms. Two boilers were fitted in the foremost boiler room, with the four boiler rooms aft (divided by a centerline bulkhead) each containing a single boiler. The forward two machinery rooms contained the port and starboard outboard turbine groups, while the aft machinery room contained boat inboard turbines. The six Kampon RO-GO three-drum boilers operated at 30 kg/cm2 and with superheating had a peak temperature of 350°C. The four turbines each output 25,000 shp, for a combined power of 100,000 shp and a resulting top speed of 35 knots.

The main armament of the Agano-class was composed of recycled Vickers 6”/50 Mark II, which had been used to arm the battlecruiser Kongo, with license-built versions arming future Japanese capital ships. Six were mounted in three twin gunhouses (lacking a rotating stalk, these were not true turrets). The guns had an elevation range of -5°/+55°, and fired 45.36 kg HE shells at a velocity of 850 m/s to a maximum range of 21,000 meters at +45°. Rate of fire was 5-6 rounds per minute. The heavy anti-aircraft battery was made up of four 8cm Type 98, 76mm in actuality, which fired a 5.99 kg shell at a velocity of 900 m/s. Maximum altitude was 9100 meters. Rate of fire was 25 rpm, but due to insufficient hoist capacity sustained rate of fire was only half of this. The light anti-aircraft battery of the class as designed was six 25mm/60 Type 96 in two triple mounts, but Yahagi had an extra four twin mounts fitted as completed, bringing her total up to fourteen guns. The 25mm AA guns fired 250 gram shells at a velocity of 900 m/s, with the maximum theoretical range and rate of fire being 6800 meters and 260 rpm. However, effective range was 2,000 meters and rate of fire 120 rpm. By far the most potent part of the armament was the torpedo battery – two Type 92 quadruple torpedo mounts, which utilized the infamous Type 93 61cm torpedo. The cruiser held sixteen torpedoes – half were in the tubes, and half in the quick-loading installations, able to load a torpedo on average within 20-30 minutes, but potentially as rapidly as 3-5 minutes. Fire control was controlled via Type 94 low-angle directors, with the aid of two 6-meter duplex coincidence rangefinders. One was installed near the director, the other atop turret No.2. These fed a Type 94 surface fire control computer, which was used to control the secondary batteries aboard battleships (for 14cm to 15.5cm guns). For control of the 8cm guns, a Type 94 high-angle director was used. As completed, Yahagi was equipped with a 21-Go surface search radar. In July of 1944, a 13-Go air search radar and a 22-Go surface search radar were fitted, which could also be used for rudimentary radar fire control measures (ranging only).
