The U.S. has completed the destruction of its chemical weapons stockpile, a historic achievement in arms control. With over 30,000 tons of chemical warfare agents once stored at various locations, the elimination marks the first complete destruction of a class of declared weapons of mass destruction under international supervision.

The process began in 1990, culminating in 2023 with the final munitions destroyed at the Pueblo Chemical Depot in Colorado and Blue Grass Army Depot in Kentucky. The Department of the Army approved the termination of surety status for BGCA on December 10, 2025. The Chemical Materials Activity will continue to support treaty obligations and manage recovered chemical materials across the country.
