Spanning more than 6,000 acres in Kingsport, Tenn., the Holston Army Ammunition Plant is the major supplier of explosive materials (primarily RDX- and HMX-based products) to the U.S. Department of Defense. The facility has state-of-the-art equipment and capabilities for nitration chemistry, acid handling and recovery, and other chemical-processing operations.
Holston recently earned industry and national acclaim for producing IMX 101, the first in a family of “insensitive munitions.” Insensitive munitions are far more stable than conventional TNT and Composition B, making the weapons systems they support safer for troops to transport and handle.
- Holston stretches more than 6,020 acres across two counties in Tennessee.
- There are over 450 buildings and storage magazines onsite.
- The plant has 107 miles of roads and 30 miles of railroads.
- Holston participates in the Armament Retooling and Manufacturing Support program, which leases onsite space to private companies.
