On December 7, 1941 over 350 Japanese aircraft launched from six aircraft carriers hammered US military installations across Oahu, Hawaii. The focal point for their attack was the elements of the US Pacific Fleet then at anchor at the US Naval Base at Pearl Harbor. This attack killed over 2,400 Americans and sank or damaged eight battleships (with two total losses), three cruisers, three destroyers, some auxiliary ships, and destroyed 183 aircraft. In turn, the Japanese lost 29 aircraft and five midget submarines.
