Hyuga battleship (1917) High resolution picture

The Hyuga was a Japanese super-dreadnought battleship launched in 1917, belonging to the Ise class. The utilization of twin turrets rendered these ships much longer than the American counterparts fitted with triple turrets, but those could achieve greater precision and resulted more reliable. On the other hand, the longer and narrower hull facilitated the high speeds demanded by the Japanese. These were also the first Japanese warships that adopted the 140-millimeter British cannon.

The ships of the Ise and Fuso class (from which those derived) were modernized during the interwar period with "pagoda style" bridge masts, new machinery and elongated stern. The remodelation of 1943 converted the Hyuga and the Ise in a hybrid of battleship and seaplane carrier, by replacing the aft turrets and superstructures with a flight deck equipped with catapults. In July 1945, the Hyuga and the Ise were sunk on their moorage at Kure by a series of attacks from American aircraft. The illustration shows the Hyuga as she was originally built; in 1922 the ship was upgraded with the installation of new rangefinders.
