Kaga was a Japanese aircraft carrier laid down in 1920, launched in November 1921, and commissioned in the Imperial Japanese Navy in March 1928. The ship was 248.6 meters long, 32.5 meters wide, and had a full displacement of 38,200 tons. The maximum speed of the aircraft carrier Kaga oscillated around 27-28 knots, its main armament consisted of 90 on-board planes.
Originally, Kaga was built as a liner under the 8 + 8 fleet expansion program, but due to international commitments by the government in Tokyo, work was stopped and the hull was to be scrapped. Ultimately, however, in 1923 it was decided to build an aircraft carrier on the hull, which actually happened. At the time of entering service, Kaga had as many as three flight decks, but during the reconstruction in 1933-1935 only one flight deck was preserved and the fuselage nose was significantly changed. During World War II, Kaga participated in the attack on Pearl Harbor in December 1941 and fought in the Bismarck Archipelago in early 1942. He also took part in the Battle of Midway (June 1942) where he was sunk by American on-board planes.
