History:

Hōshō (Japanese: 鳳翔, meaning "flying phoenix") became the first flat-deck aircraft carrier of the Imperial Japanese Navy in 1921, and was the first purpose-designed aircraft carrier in the world to be commissioned.[1]

Her predecessors in the Imperial Japanese Navy were seaplane carriers such as the Wakamiya (converted in 1920 to an aircraft carrier with forward launch platform), or the Notoro.
