The first Japanese dive-bomber appeared over Pearl Harbor at 7:55 AM (local time) on December 7, 1941. Over the next half hour, Pearl Harbor’s airfields and docked ships were subjected to a merciless assault with bombs, guns, and torpedoes. A second wave struck at 8:50 AM, and the Japanese withdrew shortly after 9:00 AM. In just over an hour, the Japanese destroyed more than 180 aircraft and destroyed or damaged more than a dozen ships. More than 2,400 U.S. military members and civilians were killed. Learn more in this infographic.
