More than 2,400 American troops died in the early hours of Dec. 7, 1941 after the Imperial Japanese Navy swarmed on Pearl Harbor in Oahu, Hawaii, hurtling the U.S. into the war.
On Friday, Hawaii Gov. Neil Abercrombie and Honolulu Mayor Kirk Caldwell lead a day of remembrance at the USS Arizona Memorial center near the site of the initial attack.
The Freedom Bell in Washington, D.C. -- cast in bronze with metal from the World Trade Center -- rang in honor of those who served in the armed forces, NBC affiliate KHNL reports. Skydivers also unfurled American Flags over Pearl Harbor.
On Saturday, the Virginia War Memorial in Richmond, Va., will host Pearl Harbor Remembrance Day with speakers and a laying of a wreath in honor of the fallen members of the military as well as civilians killed.
In Little Rock, Ark., bad weather forced the cancellation of ceremonies scheduled there for Saturday.
Soon after the attack in 1941, then-President Franklin D. Roosevelt addressed the American populace and referred to the day's events as a "sneak attack."
“Yesterday, Dec. 7, 1941 -- a day 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," said Roosevelt.
