There were 2,404 U.S. military personnel and civilians killed in the Pearl Harbor attack. While the overwhelming majority of those killed were military casualties, this total also includes 68 civilians. The greatest concentrated loss of life occurred on the USS Arizona; the 1,177 sailors, officers, and Marines killed on the Arizona constituted more than half of the American military dead at Pearl Harbor. Nearly 1,200 people were wounded in the attack. Japanese losses included 64 killed and one sailor—the copilot of a miniature submarine that drifted ashore on Oahu—captured.
