The Black Tom explosion was an act of arson by field agents of the Office of Naval Intelligence of the German Empire to destroy U.S.-made munitions awaiting shipment to the Allies during World War I. The explosions occurred on July 30, 1916, in New York Harbor, killing at least 7 people and wounding hundreds more. It also caused damage of military goods worth some $20,000,000 ($590 million in 2025 dollars). This incident, which happened before U.S. entry into World War I, also damaged the Statue of Liberty. It is one of the largest artificial non-nuclear explosions in history.
