On December 7, 1941, Japan launched a preemptive strike on the entire U.S. naval fleet located at Pearl Harbor, Hawaii. This attack involved two waves of assaults from six aircraft carriers, resulting in the destruction or damage of eight battleships, several cruisers, destroyers, and nearly two hundred aircraft. Approximately 2,400 servicemen were killed and another 1,100 were wounded.
