Sunflower Redevelopment, LLC
De Soto, KS
Project Details
This project is 9,065 acres of land that was historically utilized as a United States Army Ammunition Plant called the Sunflower Army Ammunition Plant. Construction on the plant began in 1941 and provided smokeless powder and propellants for World War II, the Korean Conflict, and the Vietnam War. At one point the world’s largest of its kind, the facility closed in 1993 and sold in 2005 by the U.S. Army to Sunflower Redevelopment, LLC. The property is being remediated under the state RCRA clean-up program and soil remedial activities are expected to be completed in 2028. In 2022, the property was given a new name, Astra Enterprise Park, and was annexed into the City of De Soto.
