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. 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 in 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.

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.

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.
