IJN Amagi
Contents
Description
The Amagi (天城 namesake: Mount Amagi) was a Japanese battlecruiser planned as part of the Imperial Japanese Navy's "Eight-Eight Fleet" programme, designed by naval engineer Yuzuru Hiraga and authorised in 1917. Laid down on 16 December 1920 at the Yokosuka Naval Yard, she was intended to be one of four Amagi-class, alongside Akagi, Atago, and Takao, all named after mountains except for Takao, which was named after a town. The design featured a lengthened Tosa-class hull with a thinner armoured belt, rearranged secondary armament, and increased power output to achieve a speed of 30 knots. Armed with ten 410 mm guns in five twin turrets, she was intended to surpass contemporary battlecruisers like HMS Hood. Construction was halted under the Washington Naval Treaty signed on 5 February 1922, when Amagi was approximately 40% complete. Plans were made to convert both Amagi and Akagi into aircraft carriers, but the Great Kantō earthquake in September 1923 caused irreparable damage to Amagi's hull while on the slipway. As a result, she was stricken from the navy list and scrapped early 1924. The incomplete Tosa-class battleship Kaga was selected as a substitute for conversion into an aircraft carrier, while Atago and Takao were cancelled and dismantled on the slipways.
The Amagi-class, IJN Amagi, project is a Japanese battlecruiser introduced in Update "Dance of Dragons". Her main feature is the exceptional firepower of 410 mm / 16.1-inch main guns, able to deal with any battleship or battlecruiser, and capable of instantly blowing up destroyers and cruisers with a single full broadside. This firepower, however, is protected by an armour scheme which can be penetrated by a number of her peers. More importantly, she's very vulnerable to aerial attacks, with her anti-air defences being symbolic at best, with just four 120 mm cannons aided by thick deck armour. Similar to other early interwar battleships, she comes equipped with torpedoes, but typically it's best to remove them from the loadout in order to avoid the risk of explosion. Overall, Amagi is an excellent, versatile warship able to dictate the balance of the battle on her own, but far from being invulnerable.
General info
Survivability and armour
Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armaments separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips on preserving survivability for the "Usage in battles" section. If necessary, use a graphical template to show the most well-protected or most vulnerable points in the armour.
Mobility
Write about the ship's mobility. Evaluate its power and manoeuvrability, rudder rerouting speed, stopping speed at full tilt, with its maximum forward and reverse speed.

Armament
Primary armament
Provide information about the characteristics of the primary armament. Evaluate their efficacy in battle based on their reload speed, ballistics and the capacity of their shells. Add a link to the main article about the weapon: {{main|Weapon name (calibre)}}. Broadly describe the ammunition available for the primary armament, and provide recommendations on how to use it and which ammunition to choose.

Secondary armament
Some ships are fitted with weapons of various calibres. Secondary armaments are defined as weapons chosen with the control Select secondary weapon. Evaluate the secondary armaments and give advice on how to use them. Describe the ammunition available for the secondary armament. Provide recommendations on how to use them and which ammunition to choose. Remember that any anti-air armament, even heavy calibre weapons, belong in the next section. If there is no secondary armament, remove this section.

Anti-aircraft armament
An important part of the ship's armament responsible for air defence. Anti-aircraft armament is defined by the weapon chosen with the control Select anti-aircraft weapons. Talk about the ship's anti-air cannons and machine guns, the number of guns and their positions, their effective range, and about their overall effectiveness – including against surface targets. If there are no anti-aircraft armaments, remove this section.
Additional armament
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
Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".
Pros:
- Main weapons with the surprising calibre of 410 mm
- Considering the calibre of the gun, excellent reload rate
- 1-ton projectile with surprising penetration power
- Reasonably fast
Cons:
- Fixed torpedo tubes, above water
- The secondary cannons have ammunition below the recommended penetration (and TNT) for the BR
- Insufficient armour for the Battle Rating
- Dangerously exposed front turret ammunition compartments
- Low protection against aircraft
History
The Amagi was a Japanese battlecruiser planned as part of the Imperial Japanese Navy's "Eight-Eight Fleet" programme, authorised on 4 April 1907, with Amagi herself being authorised in 1917 budget. Designed by naval engineer Yuzuru Hiraga in 1919 (design B-64), the Amagi-class was to be comprised four vessels: Amagi, Akagi, Atago, and Takao. The design was essentially a lengthened Tosa-class with a thinner armoured belt, rearranged secondary armament, and increased power output to achieve a speed of 30 knots. It was armed with ten 410 mm guns in five twin turrets, intended to be superior to contemporary battlecruisers like HMS Hood. Amagi was laid down at Yokosuka Naval Yard on 16 December 1920, with a planned completion date of November 1923.
Construction ceased on 5 February 1922 under the terms of the Washington Naval Treaty when Amagi was approximately 40% complete. The treaty allowed for incomplete capital ships to be converted into aircraft carriers within certain tonnage limits. An exception raised the limit to 33,000 tons, enabling the conversion of both Amagi and Akagi, corresponding to the U.S. Navy's conversions of USS Lexington and Saratoga. Conversion work on Amagi had begun, but the Great Kantō earthquake on 1 September 1923 caused irreparable stress damage to her hull while on the slipway. As a result, she was stricken from the navy list on 31 July 1924, and scrapping commenced on 14 April 1924.
Atago and Takao were cancelled and dismantled on the slipways. The incomplete Tosa-class battleship Kaga was selected as a substitute for Amagi and converted into an aircraft carrier to fulfil the two-carrier force desired by the admiralty. The guns from Amagi were recycled: three were installed as coastal artillery in Tokyo Bay, Busan, in Korea, and Iki Island guarding the Strait of Tsushima, while the remaining guns were placed in reserve and eventually scrapped in 1943 due to the need for raw materials.
