第一航空戦隊
The Japanese failed to locate the American carriers during the day and Vice Admiral Chūichi Nagumo, commander of the First Carrier Division, ordered "Ryūjō", escorted by the heavy cruiser and two destroyers, to attack Henderson Field, as per Admiral Isoroku Yamamoto's orders. American aircraft located the "Ryūjō" task force the following morning as it approached within aircraft range of Guadalcanal, as well as other enemy ships, but failed to spot the fleet carriers. Fletcher delayed his attack until further reconnaissance aircraft failed to find the other Japanese carriers and his own aircraft returned from Henderson Field. In the meantime, "Ryūjō" had launched her own airstrike against Henderson Field, although they inflicted little damage while losing seven out of 21 aircraft during the attack.
