Social:List of U.S. chemical weapons topics

Short description: None

The United States chemical weapons program began in 1917 during World War I with the creation of the U.S. Army's Gas Service Section and ended 73 years later in 1990 with the country's practical adoption of the Chemical Weapons Convention (signed 1993; entered into force, 1997). Destruction of stockpiled chemical weapons began in 1985 and is still ongoing. The U.S. Army Medical Research Institute of Chemical Defense, at Aberdeen Proving Ground, Maryland, continues to operate for purely defensive research and education purposes.
