At 09:09, the anti-aircraft guns of "Hornet" and her escorting warships opened fire as the 20 untouched Japanese torpedo planes and remaining 16 dive bombers commenced their attacks on the carrier. At 09:12, a dive bomber placed its 250 kg semi-armor-piercing "ordinary" bomb dead center on "Hornet"s flight deck, across from the island, which penetrated three decks before exploding, killing 60 men. Moments later, a 242 kg high-explosive "land" bomb struck the flight deck, detonating on impact to create an hole and kill 30 men. A minute or so later, a third bomb hit "Hornet" near where the first bomb hit, penetrating three decks before exploding, causing severe damage but no loss of life. At 09:14, a dive bomber was set on fire by "Hornet"s anti-aircraft guns; the pilot, Warrant Officer Shigeyuki Sato, deliberately crashed into "Hornet"s stack, killing seven men and spreading burning aviation fuel over the signal deck.
