Attack on Pearl Harbor

The Imperial Japanese Navy made its attack on Pearl Harbor on the morning of December 7, 1941. The surprise attack on Pearl Harbor, Oahu, Hawaii, was aimed at the Pacific Fleet of the United States Navy and its defending Army Air Corps and Marine defensive squadrons. The U.S. public was angered by the attack and rallied in support of the Armed Forces and the US Government's decision to enter World War II, initially against Imperial Japan.

The attack severely damaged or destroyed twelve American warships, destroyed 188 aircraft, and killed 2,403 American servicemen and 68 civilians. However, the Pacific Fleet's three aircraft carriers were not in port and so were undamaged, as were the base's vital oil tank farms, submarine pens, and machine shops. Using these resources, the United States was able to rebound within a year.
