Total Deaths and Official Counts
The number killed at Pearl Harbor is most commonly cited as 2,403, with 1,177 of those deaths linked to the USS Arizona. The U.S. Navy and the National Park Service maintain this figure as the standard public total for the December 7 attack. For the latest updates and source details, see the official National Park Service Pearl Harbor page here.
Beyond the immediate deaths, the attack wounded 1,178 military personnel and civilians, and many survivors later died from injuries. The 2,403 figure remains the primary reference in financial and historical analyses that compare the event’s impact to other major U.S. national security shocks. Public datasets from the Department of Defense and the National Archives continue to use this number as the baseline for casualty counts.
Breakdown by Service Branch and Ship
The Navy accounted for 2,008 deaths, the Marine Corps 109, and the Army 218, with 24 civilian fatalities. On the USS Arizona alone, 1,177 crew members were killed, making it the single largest loss of life on any ship that day. The USS Oklahoma lost 429 crew members, and the USS Utah accounted for 58 deaths, according to the official Navy history page here.
The battleship USS Arizona remains the most prominent symbol of the attack’s human cost, with a memorial that draws millions of visitors annually. The USS Utah, a former battleship converted to a target ship, also remains submerged and is considered a burial site. These ship-specific figures are frequently cited in financial and insurance analyses of wartime risk and in corporate histories of defense contractors involved in shipbuilding.
Context in U.S. Financial and Defense History
The attack directly led to the U.S. entry into World War II, reshaping global capital flows, defense spending, and corporate strategy. The number killed at Pearl Harbor is often referenced in economic analyses of wartime mobilization and in discussions of how national security events influence market volatility. Major defense contractors such as Lockheed Martin, Northrop Grumman, and RTX trace part of their growth to the post-attack expansion of the U.S. military-industrial base.
In modern finance, Pearl Harbor casualty data is used in risk modeling for geopolitical shocks and in ESG reports that assess the human impact of defense investments. The U.S. Securities and Exchange Commission requires public companies to disclose material risks from geopolitical events, and Pearl Harbor remains a key reference point in such filings here. The consistent citation of the 2,403 death toll in these documents underscores its role as a benchmark figure in both historical and financial contexts.
