Horn Island Chemical Warfare Service Quarantine Station

Horn Island Chemical Warfare Service Quarantine Station[1] was acquired in March 1943 by the U.S. Army for use as a biological weapons testing site.

[1] The 2,000-acre (8.1 km2) site[3] on Horn Island was managed and built by the Chemical Warfare Service's (CWS) Special Projects Division (SPD).

[2] Shortly before the end of World War II, on August 11, 1945, an order from the CWS declared that the Special Projects Division was to cease its activities.

[2] Horn Island Testing Station was initially established to focus its studies on insects as biological weapons.

[5] Testing at Horn Island with the toxin botulin showed that the agent was not a viable aerosol biological weapon.
