Under the South Pacific sun on December 7, 1941, troops serving the US fleet at Pearl Harbor began a calm Sunday morning unaware that Japanese bombers were headed toward America's most important Pacific base.
There, like a string of pearls draped across the docks and waterfront, was the majority of the US's naval might.
The devastating Japanese onslaught began around 8 a.m., eventually killing 2,403 Americans and wounding many others, sinking four battleships, and damaging military airfields.
The Pearl Harbor attack spurred America into World War II, leading ultimately to Allied victory over the Japanese in the Pacific and the Nazis and other Axis powers in Europe.
Here are photographs from the attack and its immediate aftermath.

Around 7 a.m., an Army radar operator spotted the first wave of the Japanese planes. The officers to whom those reports were relayed did not consider them significant enough to take action.

The Japanese also took the opportunity to attack military airfields while bombing the fleet in Pearl Harbor. The purpose of these simultaneous attacks was to destroy American planes before they could respond.
More than 90 ships were anchored at Pearl Harbor. The primary targets were the eight battleships in Battleship Row.

At about 8:10 a.m., the USS Arizona exploded as a bomb ignited its forward ammunition magazine. About half of the total number of Americans killed that day were on this ship.

The USS Shaw, a destroyer, also exploded during the two-hour attack by Japan.
The damaged USS Nevada tried to escape down the channel toward the open sea but became a target during the second wave of 170 Japanese planes, hoping to sink it in the channel and block the narrow entrance to Pearl Harbor. The ship was grounded with 60 killed on board.

Sailors at the Naval Air Station in Kaneohe, Hawaii, attempted to salvage a burning PBY Catalina in the aftermath of the Japanese attack on Pearl Harbor.
People in New York's Times Square bought newspapers with headlines like this one, "Japs Attack US." The US entered World War II after the surprise attack.
Salvage work soon began on the destroyers USS Cassin and USS Downes. The Japanese failed to damage any US aircraft carriers, which were surprisingly absent from the harbor.
About 10% of Japanese planes were lost on December 7, 1941.
