The Japanese carrier lessons Aquila needed

What should Italy have learned from Japanese carriers before converting Aquila?

Catapult and aircraft-lift design were the two most useful lessons because the intended aircraft imposed demanding launch and handling requirements.

Aquila's liner conversion needed launch and handling equipment suitable for its intended aircraft. Catapults were identified as necessary for those aircraft, alongside an effective lift design. These were the two areas in which Japanese carrier experience was considered useful. The French system was rejected as a model, without a detailed explanation of its faults.
