The now-vacant Indiana Army Ammunition Plant was built on ruffly 10,655 acres of farmland along the Ohio River between Jeffersonville and Charlestown. The facility employed more than 27,000 workers.
The plant was sectioned off into three major facilities which manufactured smokeless powder, cannon and mortar projectiles. The plant remained in full operation during the Vietnam Conflict and the Korean War.
The plant was ultimately closed when weapons technology advanced and the facility was decommissioned in the 1990s.
