The Longhorn Army Ammunition Plant (LOW) was a 8,493-acre (34.37 km2) government-owned, contractor-operated (GOCO) facility in Karnack, Texas that was established in 1942. The Monsanto Chemical Company selected the site in December 1941 to produce TNT. The plant produced 393,000,000 pounds of TNT throughout World War II. After the signing of the Intermediate-Range Nuclear Forces Treaty on December 8, 1987, the Longhorn plant was used to destroy Pershing 1a and Pershing II missiles. The plant was operated by Thiokol.

The property was transferred to the U.S. Fish & Wildlife Service in 2000 to become the Caddo Lake National Wildlife Refuge.
