Today is National Pearl Harbor Remembrance Day. Each year on Dec. 7, Pearl Harbor Survivors, veterans, and visitors come together to honor and remember the 2,403 service members and civilians who were killed during the Japanese attack on Pearl Harbor on December 7, 1941.

An additional 1,178 people were injured in the attack, which permanently sank two U.S. Navy battleships (the USS Arizona and the USS Utah) and destroyed 188 aircraft. The surprise attack prompted the US to enter WW II.

On Aug. 23, 1994, the United States Congress designated Dec. 7 as National Pearl Harbor Remembrance Day. Flags are flown at half-staff.
