About 2,400 Americans were killed in the attack on Pearl Harbor on December 7, 1941, including both military personnel and civilians.

Key numbers

  • Around 2,403–2,404 Americans were killed in the attack, depending on source rounding.
  • This total includes:
    • Navy, Army, and Marine Corps personnel (the vast majority of the dead).
* **68 civilians** who were killed during the attack.
  • Nearly 1,200 people were wounded (about 1,178–1,200 in most counts).

Notable details

  • The greatest loss of life was on the battleship USS Arizona , where 1,177 sailors, Marines, and officers were killed when the ship exploded and sank.
  • Japanese forces lost roughly 64–130 men in the attack, including aircrew and submarine personnel, again depending on how the losses are counted.

Why numbers sometimes differ

  • Some sources list 2,403 total American dead, while others list 2,404 ; the difference usually comes from whether specific later deaths from wounds are included in the immediate attack count.
  • Despite this small discrepancy, historians consistently describe Pearl Harbor as causing “about 2,400” American deaths on that day.
