Quoting from Conway (who for whatever reason spelled her name as Ryujo):
"Ryujo, built under the 1927 Programme, was planned with a single hanger, but to double the aircraft complement a second hanger was added without enlarging the ship, which turned out to be lightly built, overloaded and unstable. The flight deck measured 512ft 6in x 75ft 6in. In a reconstruction between 1934 and 1936, the armament was reduced, the hull strengthened and extra bulges added. The forecastle was raised a deck in 1940 to improve seakeeping. Ryujo was by 4 bombs and a torpedo in the Battle of the Eastern Solomons.
