Sixty-nine years ago, on December 7th, 1941, the Imperial Japanese Navy launched a surprise attack against the United States naval base in Pearl Harbor, Hawaii. Over 350 Japanese aircraft attacked in two waves, strafing, dropping bombs and torpedoes. Four U.S. Navy battleships were sunk, four other battleships were damaged, and eight other ships were either sank or damaged. 188 U.S. aircraft were destroyed, 2,402 personnel were killed and 1,282 were wounded. The following day, the United States declared war on Japan, officially entering World War II. This year’s 69th anniversary coincides with the dedication of a new $56 million Pearl Harbor visitors center. Collected here are photos from that infamous day. (34 photos total)
