Description

The Nagara-class, IJN Isuzu, 1944 is a rank III Japanese light cruiser with a battle rating of 4.7 (AB/RB/SB). It was introduced in Update "Ixwa Strike".

The IJN Isuzu is in her 1944 refit, with the sole purpose of acting as a floating anti-aircraft platform in an attempt to counter the United States' air superiority and slow down their advance. To achieve this, her 140 mm guns were replaced with a 127 mm anti-air cannons, as well as a staggering 50 x 25 mm Type 96 anti-air cannons. Giving her an unparalleled anti-air capabilities for her rank in exchange of anti-ship firepower.

Even when compared to the infamous Omaha-class cruisers such as the USS Trenton, the IJN Isuzu's protection is easily one of the worst among the range of cruisers in the game. Most of the Isuzu armour were concentrated around the engines, which were a double-layered RHA with 38 mm thickness for the outer layer and 25 mm for the inner layer. This armour can shield off the blast of HE shells, but will not protect her engines from SAP or AP shells.

As her crew compartments is mostly located on the first deck without protection, and as she has a large number of AA mounts, the Isuzu will lose a considerable amount of her crew with a few HE salvos. The ship's low crew count of 510 sailors will not help her to withstand enemy fire for long.

Mobility

Speedforward / back

AB78 / 29 km/h

RB67 / 25 km/h

With her low displacement, the IJN Isuzu is very fast and agile for a light cruiser. This will be important for the Isuzu's survival as you have to manoeuvre a lot to evade incoming fire.

Armament

Primary armament

3 х Turret2 x 5 inch/40 Type 89 cannon

Ammunition400 rounds

Vertical guidance-8° / 85°

Isuzu's main armament consists of 6 x 5 inch (12.7 cm) cannons mounted in 3 turrets. They have no protection so they can be easily knocked out. There are 2 types of shells avaible: HE and HE-TF (time-fused). While HE shells aren't as effective against ships as the previous ship's (IJN Akizuki), time fuse shells can easily destroy enemy planes, especially when they are diving. In combination with the secondary armament, this ship excels in anti-aircraft fire. Fire rate isn't quick, but it is enough to aim a few shells at air targets.

Secondary armament

17 х Turret25 mm/60 Type 96 automatic cannon

Ammunition1500 rounds

Belt capacity15 rounds

Fire rate261 shots/min

11 х Turret3 x 25 mm/60 Type 96 automatic cannon

Ammunition4500 rounds

Belt capacity15 rounds

Fire rate261 shots/min

As an anti-air cruiser, the Isuzu is equipped with 50 x 25 mm Type 96 AA cannons placed all over the ship, a large amount of AA guns of a Japanese ship (only behind the Tone with 62 AA guns). The sheer amount of the guns give the Isuzu a massive burst output that will deter any aerial threats from getting close.

Additional armament

Setup 18 x 610 mm Type 93 Model 1, Mod 2 torpedo

Describe the available additional armaments of the ship: depth charges, mines, torpedoes. Talk about their positions, available ammunition and launch features such as dead zones of torpedoes. If there is no additional armament, remove this section.

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:

• 127 mm guns have good rate of fire and good traverse speed
• 50 x 25 mm AA guns gives the Isuzu one of the best AA defence capability in the Japanese fleet
• Very good top speed and mobility
• Equipped with deadly Type 93 torpedoes

Cons:

• Extremely poor protection
• Engines and transmission can be easily damaged
• 127 mm guns lack stopping power against enemy cruisers
• Will be always outgunned by every cruisers and even some destroyers
• Open turrets with lack of gun shield, can be easily disabled

History

Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the ship and adding a block "/History" (example: https://wiki.warthunder.com/(Ship-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the ship's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
