 The loss of Taihō and Shōkaku left Zuikaku to recover the Division 's few remaining aircraft after their heavy losses ( only 102 aircraft remained aboard the seven surviving carriers by the evening ) and the 1st Mobile Fleet continued its withdrawal towards Okinawa . The Americans did not spot the Japanese carriers until the afternoon of the following day and launched a large airstrike that only succeeded in hitting Zuikaku with a single bomb that started a fire in the hangar .
