The explosion occurred at the Accurate Energetic Systems plant in the town of Buckshort, about 100 km southwest of Nashville, the capital of Tennessee.
The factory produced explosives and ammunition for the army, as well as the aerospace and shipbuilding industries. She received many contracts from the US Army and Navy.
Humpreys County Sheriff Chris Davis said two people survived because they were outside the plant at the time of the explosion.
The explosion, the causes of which are currently being determined, completely destroyed the factory building and cars parked nearby.
