On December 7, 1941, Japanese planes attacked the United States Naval Base at Pearl Harbor External, Hawaii Territory, killing more than 2,300 Americans. The U.S.S. Arizona was completely destroyed and the U.S.S. Oklahoma capsized. A total of twelve ships sank or were beached in the attack and nine additional vessels were damaged. More than 160 aircraft were destroyed and more than 150 others damaged.
A hurried dispatch from the ranking United States naval officer in Pearl Harbor, Admiral Husband Edward Kimmel, Commander in Chief of the United States Pacific Fleet, to all major navy commands and fleet units provided the first official word of the attack at the ill-prepared Pearl Harbor base. It said simply: AIR RAID ON PEARL HARBOR X THIS IS NOT DRILL.

Within days, Japan’s allies, Germany and Italy, declared war on the United States, and the country began a rapid transition to a wartime economy by building up armaments in support of military campaigns in the Pacific, North Africa, and Europe.
