The planning sequence begins with two attacks followed by an assessment of the information returned. Additional waves are treated as compatible with Japanese doctrine and established practice. A third wave would fit that approach, and a fourth is not considered doctrinally excluded. Stopping after two strikes on so important a target is therefore judged unusual. The explanation returns to the unlocated American carriers, which could require the Japanese aircraft to defend or attack at sea.
