Aftermath: USS West Virginia (severely damaged), USS Tennessee (damaged), and the USS Arizona (sunk).
At 7:55 a.m. on December 7, 1941 in Hawaii, a Japanese dive bomber displaying the Rising Sun of Japan appeared above the island of Oahu. 360 Japanese warplanes followed, descending on the U.S. naval base at Pearl Harbor in a brutal assault. The surprise attack served as a critical setback against the U.S. Pacific fleet and drew the United States into the Second World War.
President Franklin D. Roosevelt and his advisers assumed a looming Japanese attack was probable, but nothing had been done to secure the vital naval base at Pearl Harbor.
Much of the Pacific fleet was rendered useless: Five of eight battleships, three destroyers, and seven other ships were sunk or severely damaged, and more than 200 aircraft were destroyed. A total of 2,400 Americans were killed and 1,200 were wounded, many while heroically attempting to ward off the attack.
Battleship USS West Virginia took two aerial bombs, both duds, and seven torpedo hits, one of which may have come from a midget submarine.
Fortunately for the United States, all three Pacific fleet carriers were out at sea on training maneuvers. These giant aircraft carriers would have their revenge against Japan six months later at the Battle of Midway, defeating the previously invincible Japanese navy in a spectacular victory.
The day after Pearl Harbor was bombed, President Roosevelt appeared before a joint session of Congress and declared, "Yesterday, December 7, 1941 - a date which will live in infamy - the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan."
This week, President Obama proclaimed National Pearl Harbor Remembrance Day, 2013. He stated: “More than seven decades ago, on a calm Sunday morning, our Nation was attacked without warning or provocation. The bombs that fell on the island of Oahu took almost 2,400 American lives, damaged our Pacific Fleet, challenged our resilience, and tested our resolve. On National Pearl Harbor Remembrance Day, we honor the men and women who selflessly sacrificed for our country, and we show our enduring gratitude to all who fought to defend freedom against the forces of tyranny and oppression in the Second World War.”
Today, the USS Arizona Memorial on the island of Oahu honors the lives lost on the day of the attack. Visitors to the memorial reach it via vessels from the naval base at Pearl Harbor. It commemorates "initial defeat and ultimate victory" of all lives lost on December 7, 1941.

After a systematic search for survivors, formal salvage operations began. Around Pearl Harbor, divers from the Navy (shore and tenders), the Naval Shipyard, and civilian contractors (Pacific Bridge and others) began work on the ships that could be refloated. They patched holes, cleared debris, and pumped water out of ships. Navy divers worked inside the damaged ships. Within six months, five battleships and two cruisers were patched or refloated so they could be sent to shipyards in Pearl Harbor and on the mainland for extensive repair. Intensive salvage operations continued for another year, a total of some 20,000 man-hours under water.
