The Tennessee explosion occurred at Accurate Energetic Systems, an ammunition and explosives facility located in Hickman County, Tennessee. This plant is about 60 miles southwest of Nashville near the town of McEwen, close to the boundary line between Hickman and Humphreys counties. The explosion happened early Friday morning (October 10, 2025) around 7:45 a.m. local time. The blast was so powerful that it shook homes miles away and produced a large smoke plume. The building at the plant was obliterated, and debris was scattered over about half a square mile. This facility specializes in processing explosives for military, demolition, aerospace, and mining uses, but it does not manufacture ammunition itself. The cause of the explosion is under investigation. Several fatalities were confirmed, and 18 people remained unaccounted for after the explosion. Local sheriffs described the scene as one of the most devastating in their careers and have been in contact with families affected by the incident.
