The Japanese attack force under the command of Admiral Nagumo, consisting of six carriers with 423 planes, is about to attack.
6 a.m., the first attack wave of 183 Japanese planes takes off from the carriers located 230 miles north of Oahu and heads for the U.S. Pacific Fleet at Pearl Harbor
7:02 a.m., two Army operators at Oahu's northern shore radar station detect the Japanese air attack approaching and contact a junior officer who disregards their reports, thinking they are American B-17 planes which are expected in from the U.S. west coast.
7:15 a.m., a second attack wave of 167 planes takes off from the Japanese carriers and heads for Pearl Harbor.
7:53 a.m., the first Japanese assault wave, with 51 'Val' dive bombers, 40 'Kate' torpedo bombers, 50 high level bombers and 43 'Zero' fighters, commences the attack with flight commander, Mitsuo Fuchida, sounding the battle cry: "Tora! Tora! Tora!" (Tiger! Tiger! Tiger!).
The Americans are taken completely by surprise. The first attack wave targets airfields and battleships. The second wave targets other ships and shipyard facilities. The air raid lasts until 9:45 a.m. Eight battleships are damaged, with five sunk. Three light cruisers, three destroyers and three smaller vessels are lost along with 188 aircraft. The Japanese lose 27 planes and five midget submarines which attempted to penetrate the inner harbor and launch torpedoes.
