Unforgettable photos from the Japanese attack on Pearl Harbor, 75 years ago today

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 at 7:48 a.m., eventually killing 2,402 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.
