Naval aviation as an offset and surprise weapon

Surprise offered Japan a practical means of turning limited resources into a sharper initial blow. Different timing, direction, or method could make naval aircraft disproportionately valuable against a stronger force. That logic made aviation an offset capability from the arm's early development rather than a late imitation of American carrier doctrine. The central caveat is that even a successful surprise attack may leave a much larger opponent with enough strength to recover and dominate later rounds of a war.
