Description

The Yubari-class, IJN Yubari, 1944 (夕張, namesake: Yūbari River) was built between 1922 and 1923 as an experimental test bed for various new innovations made by the Imperial Japanese Navy, such as weight-saving design and the then state-of-the-art Kampon boilers. As a result, the Yubari ended up being something between a very heavy destroyer and a very light cruiser.

She was introduced in Update "Direct Hit". As a test-bed for Japanese naval development, her role isn't quite standard. Playing closely to a well-armed gun destroyer, packing 140 mm with potent SAP shells and the sluggish manoeuvrability of a cruiser. Survivability is notable for what she faces on the seas, offering the armour survivability closer to a cruiser, with the crew count closer to a destroyer

The Yubari is a very small cruiser, being only slightly longer and heavier than the Akizuki at 138.9 metres in length and 4,450 tons of displacement. When combined with her decent mobility, she can be somewhat harder to hit at range.

Being such a small and very light cruiser also means that the Yubari doesn't have much protection. Her armour profile is roughly the same as the Kuma with smaller shell rooms, which means it's very poorly protected against any other cruisers and even destroyers at closer range. Yubari's fatal weak spot is her rear ammunition storage that sits above the waterline and is very easy to hit and detonate.

Mobility

Speedforward / back

AB69 / 32 km/h

RB59 / 27 km/h

Yūbari offers speeds closer to destroyers over light cruisers at the cost of still getting a rather far large fleet spawn. Her speed and small figure allow her to dodge shells with more ease compared to a regular-sized cruiser.

Armament

Primary armament

Ammunition410 rounds

Vertical guidance-5° / 30°

The armament of the Yūbari is rather lacklustre for a cruiser, but it should be kept in mind that she's built as a testbed and plays closer to a destroyer rather than a cruiser with her size, speed and fewer (but larger) guns compared to regular destroyers. Her 4 x 140 mm cannons come in 2 dual-mount turrets in the front and back of the ship, coordinating the 120 mm/45 in main and auxiliary calibre shooting with one button allows the captain to output quite the forward firepower, leaving your target size minimal, while still dishing out considerable damage against destroyers and light cruisers.

Broadsiding to use the back turret offers more damage output but makes the ship a larger target so keep that in mind. The armour should suffice against weaker destroyers, but facing heavy-end destroyers and other cruisers, it's ill-advised.

Secondary armament

Turret120 mm/45 10th year type cannon

Ammunition250 rounds

As mentioned with the primary, the auxiliary calibre should be fired in unison with the primary guns as it doesn't offer too much on its own. The 120 mm is mounted in a single mount turret as the most forward turret 1 level below the forward primary.

Having 25 x 25 mm Type 96s, Yūbari offers a decent amount of close anti-air cover for herself and nearby vessels, causing havoc among small patrol boats and shredding them within ~2 km.

Additional armament

Setup 18 x 610 mm Type 8 No.2 wet-heater torpedo

Carrying 2 torpedo launchers with 2 tubes each, Yūbari offers 4 torpedoes on the ready with 4 more on reserve ready for reloading. The turrets are a rather old model and are slow to traverse.

The Type 8s aren't the top-of-the-line Type 93 Long Lance torpedoes but still offer the same bang and range without the speed.

Usage in battles

Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don't try to provide a single point of view, but give the reader food for thought. 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:

• Small size (comparable to some destroyers) makes her harder to target
• Sufficient armaments and armour to take on any destroyers at range
• Good AA armament

Cons:

• Terrible survivability against other cruisers
• Only 4 main guns, very poor damage output against cruisers
• Carries only 8 torpedoes, only 4 can be launched before reloading
• Average top speed and mobility
• Rear ammo racks sit above the waterline and are thus prone to detonation
• Outclassed by almost every cruiser she will face
• Extremely short SAP fuse delay makes damaging enemy ships' internal modules difficult

History

The Imperial Japanese Navy authorized the construction of the Yubari class during the First World War as part of the 8-4 Fleet Construction Program. Due to budgetary constraints, the ship did not start construction until 1922. Like many pre-war Japanese vessels, it sought to put as much weaponry as possible on a limited size hull. It was designed to have the hitting power of a 5,500-ton class cruiser in a 4,500-ton package. While in many cases, this resulted in overweight, top-heavy and unseaworthy boats, the Yubari class accomplished this using an intelligent application of structural armour.
