First Carrier Division
In mid-1936, the ship was used to evaluate a dozen Aichi D1A dive bombers and dive-bombing tactics. She also embarked at that time 24 A4N1 fighters, plus four and eight spare aircraft respectively. In September, "Ryūjō" resumed her role as flagship of First Carrier Division, now commanded by Rear Admiral Saburō Satō. Her air group now consisted of a mixture of B3Y1 torpedo bombers, D1A1 dive bombers and A2N fighters, but her torpedo bombers were transferred after fleet maneuvers in October demonstrated effective dive bombing tactics. Captain Katsuo Abe assumed command of the ship on 16 November.
