Japanese aircraft carrier Ryūjō

Ryūjō (Japanese: 龍驤 "Prancing Dragon") was a light aircraft carrier built for the Imperial Japanese Navy (IJN) during the early 1930s. Small and lightly built to exploit a loophole in the Washington Naval Treaty of 1922, she proved to be top-heavy and only marginally stable and was back in the shipyard for modifications within a year of completion.
