Attack History On Sunday December 7 th 1941 the Japanese launched a surprise attack against the American Pacific Fleet stationed at Pearl Harbour. By planning the attack on a Sunday the Japanese Admiral Nagumo hoped to catch the entire American Pacific Fleet in port. As luck would have it three aircraft carriers and one battleship were not in port. The aircraft carrier U.S.S. Enterprise was returning from delivering some aircraft, the aircraft carrier U.S.S. Lexington was away ferrying aircraft, the aircraft carrier U.S.S. Saratoga and the battleship U.S.S. Colorado were undergoing repairs in the United States. In spite of the latest intelligence reports about the missing aircraft carriers, his main targets, Admiral Nagumo decide to continue his attack with his task force of six aircraft carriers and escort vessels.

At a range of 230 miles North of Oahu at 06:00 hours he launched the first wave of his surprise attack. This consisted of 183 aircraft, a mix of Kate torpedo bombers, Val dive bombers, Zero fighters and high altitude bombers. Their targets were the American Pacific Fleet moored in Pearl Harbour and the military airfields at Hickham Field, Kaneahe Field and Ewa Field. At 07:15 hours the second wave of 167 aircraft was launched consisting of the same mix of aircraft and with the same targets. At 07:53 hours the first wave stuck at airfields and the harbour. Within the next hour the second wave arrived and continued the attack. When it was over, the United States losses were considerable.
