Description
Amagi, 1939 Construction Yokosuka Naval Yard; Yokosuka, Japan Laid down: 16 December 1920 Scrapped: 14 April 1924 Specifications 41,217 tons displacement, standard 251.8m length 30.8m beam 9.5m draft Machinery 19 boilers, 4 turbines Performance 30 knots at 131,200 shaft horsepower 8,000nm at 14 knots Armor Main belt: 254mm Decks: 98mm Bulkheads: 73mm Barbettes and Turrets: 229-280mm barbette, 356mm turrets Conning tower: 356mm Armament Main Ten (5x2) 410mm guns Secondary Sixteen (16x1) 140mm guns Anti-Aircraft Four (4x1) 120mm guns Torpedoes Eight (2x4) 610mm torpedo tubes

History Design
The Amagi class (天城型 Amagi-gata?) was a series of four battlecruisers planned for the Imperial Japanese Navy as part of the so-called Eight-eight fleet. The ships were to be named Amagi, Akagi, Atago, and Takao (initially named Ashitaka), after the mountains Amagi, Akagi, Atago, and Takao. The Amagi design was essentially a lengthened version of the Tosa-class battleship, but with a thinner armored belt and deck and a modified secondary battery arrangement.
Limitations imposed by the 1922 Washington Naval Treaty prevented the class from being completed as designed. However, the treaty had a limited allowance for hulls already under construction to be converted into aircraft carriers. Amagi and Akagi were both intended for conversion, but an earthquake damaged the hull of Amagi so extensively that the ship was scrapped. Akagi was reconstructed as an aircraft carrier and served with distinction as part of the Kido Butai during the Second World War, participating in the Japanese attack on Pearl Harbor before being sunk at the Battle of Midway.
Amagi’s stock Hull (A) represents how the ship would have looked after a theoretical mid-1930's refit (had she been completed), while Hull (B) is a what-if variant circa 1944.
Historical Inaccuracies
Her 25 mm anti-aircraft guns did not begin development until 1935. The triple mount version only entered service in 1941.

Actual anti-aircraft complement was six (6) 120mm L/45 guns.
