How effective was Japanese cruiser and battleship aviation at Midway and Leyte Gulf?
Short answerIt worked within its doctrine, but that dispersed cruiser-based system was ill-suited to mass fleet searches; dedicated reconnaissance carriers could have coordinated scouting better.
NotesThe system performed according to the doctrine built around cruiser scouts and vice-admiral-led distributed groups. Large carrier battles at Midway, Coral Sea, and Leyte Gulf instead demanded many search aircraft launched and coordinated quickly. Dispersed cruiser flights made sense for an attritional campaign but created command friction when one task force needed a coherent search plan. Light carriers such as Hosho or Ryujo might have served better as dedicated reconnaissance carriers while protecting the main strike carriers' air groups.
