1944 - Port Chicago disaster
An ammunition ship explodes while being loaded in Port Chicago, California, killing 332 people on this day in 1944. The United States’ World War II military campaign in the Pacific was in full swing at the time. Poor procedures and lack of training led to the disaster.
Port Chicago, about 30 miles north of San Francisco, was developed into a munitions facility when the Naval Ammunition Depot at Mare Island, California, could not fully supply the war effort. By the summer of 1944, expansion of the Port Chicago facility allowed for loading two ships at once around the clock. The Navy units assigned to the dangerous loading operations were generally segregated African-American units. For the most part, these men had not been trained in handling munitions. Additionally, safety standards were forgotten in the rush to keep up frenetic loading schedules.
