Of the 108 Japanese aircraft involved in this attack, 11 were destroyed, 14 were heavily damaged, and 29 were damaged. The initial Japanese attack did not destroy Midway: American bombers could still use the airbase to refuel and attack the Japanese invasion force. Most of Midway's land-based defenses were intact. Another air attack to destroy Midway's defences would be necessary if troops were to be able to go ashore by 7 June.
