At this time the 15th Kōkūtai had a nominal strength of one unit of carrier fighters (12 aircraft), one unit of carrier bombers (12 aircraft) and a half unit carrier attack aircraft (six aircraft). Actual strength was nine A4Ns, nine A5Ms, 18 carrier bombers and nine carrier attack aircraft. Primary duties were to cooperate in the army’s Hankou operations and in particular air defense in the areas along the Yangtze River.
