Pine Bluff Chemical Activity (abbreviated PBCA) 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. [1]
Pine Bluff Arsenal stored 90,409 M55 GB rockets, 19,608 M55 VX rockets, 9,378 M23 VX landmines and 3,705 mustard ton containers. It was also the home for the Binary Chemical Weapons Facility. The facility created one of the two toxic agents that would combine to form sarin. Construction of the diphenylcyanoarsine (DC) facility began in the mid-1980s and a classified number of canisters were produced. A facility was also planned to produce DC, but it was never constructed.
A facility was planned to produce QL (diisopropyl aminoethylmethyl phosphonite), a precursor to the nerve agent VX. Construction began in the late 1980s, but it was mothballed prior to completion in the early 1990s as part of the chemical weapons treaties. Only partial construction of the Bigeye Bomb (BLU-80) fill and close facility at the Pine Bluff Integrated Production Facilities (IBPF) was completed and no filling of the air-delivered binary bomb ever took place. The Army only produced a few of these bombs. They remained empty or filled with a safe, simulated chemical for test purposes. International treaty inspectors witnessed the destruction of all these bombs in the summer of 1999. [2]
The Pine Bluff Chemical Agent Disposal Facility was completed in 2002, and the Army began weapons disposal in March 2005. By May 2007, the facility had destroyed all of its GB (sarin)-containing rockets and began processing VX-containing munitions. In February 2008 they processed their last VX-containing rocket and in May 2008 began processing VX landmines. [3] Landmine processing was completed in June 2008 and the facility changed over to processing ton containers of mustard gas, the last remaining chemical weapons on site. [4] Workers began destruction of mustard agent-filled ton containers in December 2008. The facility reached 100% destruction of its total chemical stockpile of 3,850 metric tons on November 12, 2010. [5] The facility and Pine Bluff Chemical Activity finalized closure in January 2014. [6]
Sarin is an extremely toxic organophosphorus compound. A colourless, odourless liquid, it is used as a chemical weapon due to its extreme potency as a nerve agent. Exposure can be lethal even at very low concentrations, where death can occur within one to ten minutes after direct inhalation of a lethal dose, due to suffocation from respiratory paralysis, unless antidotes are quickly administered. People who absorb a non-lethal dose and do not receive immediate medical treatment may suffer permanent neurological damage.
VX is an extremely toxic synthetic chemical compound in the organophosphorus class, specifically, a thiophosphonate. In the class of nerve agents, it was developed for military use in chemical warfare after translation of earlier discoveries of organophosphate toxicity in pesticide research. In its pure form, VX is an oily, relatively non-volatile liquid that is amber-like in colour. Because of its low volatility, VX persists in environments where it is dispersed.
The United States is known to have possessed three types of weapons of mass destruction: nuclear, chemical, and biological weapons. As the country that invented nuclear weapons, the U.S. is the only country to have used nuclear weapons on another country, when it detonated two atomic bombs over two Japanese cities of Hiroshima and Nagasaki during World War II. It had secretly developed the earliest form of the atomic weapon during the 1940s under the title "Manhattan Project". The United States pioneered the development of both the nuclear fission and hydrogen bombs. It was the world's first and only nuclear power for four years, from 1945 until 1949, when the Soviet Union produced its own nuclear weapon. The United States has the second-largest number of nuclear weapons in the world, after the Russian Federation.
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 Edgewood Chemical Activity was a U.S. Army site located in Edgewood, Maryland that stored chemical weapons. Its construction was started by Ordnance Corps in November 1917 and completed in less than a year. The arsenal was to employ about 10,000 civilian and military personnel in fabrication of chemical weapons and filling gas shells with phosgene, chlorpicrin, chlorine and mustard gas. Since 1941, the U.S. Army stored approximately five percent of the nation's original chemical agent in steel ton containers, at the Edgewood Area of Aberdeen Proving Ground.
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 Deseret Chemical Depot was a U.S. Army chemical weapon storage area located in Utah, 60 miles (100 km) southwest of Salt Lake City. It is related to the Tooele Chemical Agent Disposal Facility.
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.
The Pine Bluff Arsenal is a United States Army installation in Jefferson County, Arkansas, about eight miles northwest of Pine Bluff and thirty miles southeast of Little Rock.
Operation Red Hat was a United States Department of Defense movement of chemical warfare munitions from Okinawa, Japan to Johnston Atoll in the North Pacific Ocean, which occurred in 1971.
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.
Isopropyl aminoethylmethyl phosphonite, also known as O-(2-diisopropylaminoethyl) O′-ethyl methylphosphonite, is a precursor chemical to the nerve agent VX and VR-56. It is a colorless liquid with a strong fishy odor, and is slightly soluble in water.
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.
The Weteye bomb was a U.S. chemical weapon designed for the U.S. Navy and meant to deliver the nerve agent sarin. The Weteye held 160 kg (350 lb) of liquid sarin and was officially known as the Mk 116. Stockpiles of Weteyes were transferred to Utah in the 1980s amidst controversy and protest.
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, Kentucky, and the U.S. Army Pueblo Chemical Depot, Colorado. 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."
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.
