Johnston Atoll is an unincorporated territory of the United States, under the jurisdiction of the United States Air Force (USAF). The island is closed to public entry, and limited access for management needs is only granted by a letter of authorization from the USAF. A special use permit is also required from the United States Fish and Wildlife Service (USFWS) to access the island by boat or enter the waters surrounding the island, which are designated as a National Wildlife Refuge and part of the Pacific Remote Islands Marine National Monument. The Johnston Atoll National Wildlife Refuge extends from the shore out to 12 nautical miles, continuing as part of the National Wildlife Refuge System out to 200 nautical miles. The Pacific Remote Islands Marine National Monument extends from the shore out to 200 nautical miles.
Chemical warfare (CW) involves using the toxic properties of chemical substances as weapons. This type of warfare is distinct from nuclear warfare, biological warfare and radiological warfare, which together make up CBRN, the military acronym for chemical, biological, radiological, and nuclear, all of which are considered "weapons of mass destruction" (WMDs), a term that contrasts with conventional weapons.
The Umatilla Chemical Depot (UMCD), based in Umatilla, Oregon, was a U.S. Army installation in the United States that stored chemical weapons. The chemical weapons originally stored at the depot consisted of various live munitions and storage containers each holding 1 short ton GB or VX nerve agents or HD blister agent. All munitions had been safely destroyed by 2011 and base closure operations were still ongoing as of 2022.
The Tooele Chemical Agent Disposal Facility or TOCDF, is a U.S. Army facility located at Deseret Chemical Depot in Tooele County, Utah that was used for dismantling chemical weapons.
The United States Army Chemical Materials Activity (CMA) is a separate reporting activity of the United States Army Materiel Command (AMC). Its role is to enhance national security by securely storing the remaining U.S. chemical warfare materiel stockpiles, while protecting the work force, the public and the environment to the maximum extent.
Pine Bluff Chemical Activity is a subordinate organization of the United States Army Chemical Materials Agency located at Pine Bluff Arsenal in Pine Bluff, Arkansas. The U.S. Army stored approximately twelve percent of its original chemical weapons at the Pine Bluff Arsenal since 1942. Destruction of the last chemical weapons occurred on November 12, 2010.
Blue Grass Army Depot (BGAD) is a U.S. Army Joint Munitions Command storage facility for conventional munitions and chemical weapons. The facility is located in east central Kentucky, southeast of the cities of Lexington and Richmond, Kentucky. The 14,494-acre (58.66 km2) site, composed mainly of open fields and wooded areas, is used for munitions storage, repair of general supplies, and the disposal of munitions. The installation is used for the storage of conventional explosive munitions as well as assembled chemical weapons. The depot primarily is involved in industrial and related activities associated with the storage and maintenance of conventional and chemical munitions.
Anniston Chemical Activity was a U.S. Army chemical weapon storage site located in Alabama. The Army had stored approximately seven percent of the nation’s original chemical weapons stockpile at the Anniston Army Depot since the early 1960s. In August 2003, the Army began disposing of these weapons at the Anniston Chemical Agent Disposal Facility. Destruction of the base's stockpile of VX was begun on July 23, 2006. By December 2008, all of the VX on site had been destroyed. Destruction of mustard-filled munitions began on July 2, 2009 after several months of retooling. By July 2010, it had destroyed by incineration 75% of the depot's total stockpile including all 437 tons of GB (sarin) and all VX nerve agent on site. On September 22, 2011, the last mustard gas shells were burned, completing chemical weapons disposal at the facility. The facilities were scheduled for dismantlement by about 2013 and some of the weapon-handling equipment was planned for transfer to the depots at Kentucky and Colorado. Local government emergency departments are expecting to lose millions in annual funding from the federal government related to the presence of the chemical depot and as many as 1000 jobs will be cut on the base. According to the US Army Corps of Engineers the disposal and closure of Anniston Chemical Activity were completed on May 7, 2013. Following the closure, other uses for the incinerators were explored, but ultimately they were demolished.
Beginning in the mid-1930s, Japan conducted numerous attempts to acquire and develop weapons of mass destruction. The 1943 Battle of Changde saw Japanese use of both bioweapons and chemical weapons, and the Japanese conducted a serious, though futile, nuclear weapon program.
The Blue Grass Chemical Agent-Destruction Pilot Plant (BGCAPP) is a facility built to destroy the chemical weapons stockpile at the Blue Grass Army Depot (BGAD), near Richmond, Kentucky.
Johnston Atoll Chemical Agent Disposal System (JACADS) was the U.S. Army's first chemical munitions disposal facility. It was located on Johnston Island, at Johnston Atoll and completed its mission and ceased operation in 2000.
The M55 rocket was a chemical weapon developed by the United States in the 1950s. The United States Army produced both Sarin and VX unitary warheads for the M55.
Operation Steel Box, also known as Operation Golden Python, was a 1990 joint U.S.–West German operation which moved over 100,000 U.S. chemical weapons from Germany to Johnston Atoll.
The Program Executive Office, Assembled Chemical Weapons Alternatives is responsible for the safe and environmentally sound destruction of chemical weapons stockpiles previously stored at the Blue Grass Army Depot in Kentucky, and the U.S. Army Pueblo Chemical Depot in Colorado, now known as the U.S. Army Chemical Materials Activity-West. In 1996, the United States Congress established the ACWA program to test and demonstrate alternative technologies to baseline incineration for the destruction of chemical weapons. The ACWA program oversaw the design and construction of the two chemical weapons destruction pilot plants – the Pueblo Chemical Agent-Destruction Pilot Plant (PCAPP) in Colorado and the Blue Grass Chemical Agent-Destruction Pilot Plant (BGCAPP) in Kentucky. As of July 7, 2023, PCAPP and BGCAPP have both concluded destruction of their respective stockpiles of chemical weapons. PEO ACWA will continue to oversee both plants through their closure phases, each estimated to take three to four years.
Throughout history, chemical weapons have been used as strategic weaponry to devastate the enemy in times of war. After the mass destruction created by WWI and WWII, chemical weapons have been considered to be inhumane by most nations, and governments and organizations have undertaken to locate and destroy existing chemical weapons. However, not all nations have been willing to cooperate with disclosing or demilitarizing their inventory of chemical weapons. Since the start of the worldwide efforts to destroy all existing chemical weapons, some nations and terrorist organizations have used and threatened the use of chemical weapons to leverage their position. Examples of the use of chemical weapons since World War II are Iraq’s Saddam Hussein on the Kurdish village Halabja in 1988 and their employment against civilian passengers of the Tokyo subway by Aum Shinrikyo in 1995. The efforts made by the United States and other chemical weapon destruction agencies intend to prevent such use, but this is a difficult and ongoing effort. Aside from the difficulties of cooperation and locating chemical weapons, the methods to destroy the weapons and to do this safely are also a challenge.
A chemical weapon (CW) is a specialized munition that uses chemicals formulated to inflict death or harm on humans. According to the Organisation for the Prohibition of Chemical Weapons (OPCW), this can be any chemical compound intended as a weapon "or its precursor that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action. Munitions or other delivery devices designed to deliver chemical weapons, whether filled or unfilled, are also considered weapons themselves."
Operation Pacer IVY was a 1972 operation of the U.S. Air Force that removed Agent Orange from South Vietnam and stored it on Johnston Atoll. IVY was presumably selected as an abbreviation of InVentorY. Operation Pacer HO refers to an associated program of the United States Department of Defense (DoD), dealing with the disposition of Agent Orange from Vietnam.
The 267th Chemical Company was a military unit of the U.S. Army Chemical Corps responsible for the surety of chemical warfare agents dubbed "RED HAT" deployed to the Islands of Okinawa, Japan and subsequently Johnston Atoll in the Pacific Ocean. A recently discovered Army document reveals that the true mission of the 267th Chemical Company was the operation of the Okinawa deployment site as part Project 112. Project 112 was a 1960s biological warfare field test program that was conducted by the Deseret Test Center. Okinawa is not listed as a test site under Project 112 by the U.S. Department of Defense.
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. Destruction of stockpiled chemical weapons began in 1986 and was completed on July 7, 2023. The U.S. Army Medical Research Institute of Chemical Defense (USAMRICD), at Aberdeen Proving Ground, Maryland, continues to operate.
