Mustard gas or sulfur mustard is any of several chemical compounds that contain the chemical structure SCH2CH2Cl. In the wider sense, compounds with the substituent SCH2CH2X and NCH2CH2X are known as sulfur mustards and nitrogen mustards (X = Cl, Br), respectively. Such compounds are potent alkylating agents, which can interfere with several biological processes. Also known as mustard agents, this family of compounds are infamous cytotoxic and blister agents with a long history of use as chemical weapons. The name mustard gas is technically incorrect: the substances, when dispersed, are often not gases but a fine mist of liquid droplets. Sulfur mustards are viscous liquids at room temperature and have an odor resembling mustard plants, garlic, or horseradish, hence the name. When pure, they are colorless, but when used in impure forms, such as in warfare, they are usually yellow-brown. Mustard gases form blisters on exposed skin and in the lungs, often resulting in prolonged illness ending in death. The typical mustard gas is the organosulfur compound called bis(2-chloroethyl) sulfide.
Lewisite (L) (A-243) is an organoarsenic compound. It was once manufactured in the U.S., Japan, Germany and the Soviet Union for use as a chemical weapon, acting as a vesicant and lung irritant. Although the substance is colorless and odorless in its pure form, impure samples of lewisite are a yellow, brown, violet-black, green, or amber oily liquid with a distinctive odor that has been described as similar to geraniums.
SS John W. Brown is a Liberty ship, one of two still operational and one of three preserved as museum ships. As a Liberty ship, she operated as a merchant ship of the United States Merchant Marine during World War II and later was a vocational high school training ship in New York City for many years. Now preserved, she is a museum ship and cruise ship berthed at Pier 13 in Baltimore Harbor in Maryland.
A cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped.
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 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.
USS LST-519 was an LST-491-class tank landing ship built for the U.S. Navy in World War II. She was later renamed USS Calhoun County (LST-519) after counties in eleven states in the United States.
Seatrain Lines, officially the Over-Seas Shipping Company, was a shipping and transportation company conducting operations in the Americas and trans-Pacific regions. Seatrain Lines began intermodal freight transport in December 1928 by transporting entire loaded railroad freight cars between the United States and Cuba. The specially designed ship Seatrain, built in England, was followed in 1932 by two larger ships built in the United States and in 1939 by two additional ships. By the outbreak of World War II the company was operating five ships that became important in the war effort and basis for the design of fifty new ships for military use. A series of business setbacks amid the rise of containerized shipping left the company in perilous financial condition in the 1970s. Seatrain Lines shut down in 1981 after filing for bankruptcy.
Operation Sandcastle was a United Kingdom non-combat military operation conducted between 1955–1956. Its purpose was to dispose of chemical weapons by dumping them in the sea.
Operation CHASE was a United States Department of Defense program for the disposal of unwanted munitions at sea from May 1964 until the early 1970s. Munitions were loaded onto ships to be scuttled once they were at least 250 miles offshore. While most of the sinkings involved conventional weapons, four of them involved chemical weapons. The disposal site for the chemical weapons was a three-mile (5 km) area of the Atlantic Ocean between the coast of the U.S. state of Florida and the Bahamas. The CHASE program was preceded by the United States Army disposal of 8,000 short tons of mustard and lewisite chemical warfare gas aboard the scuttled SS William C. Ralston in April 1958. These ships were sunk by having Explosive Ordnance Disposal (EOD) teams open seacocks on the ship after they arrived at the disposal site. The typical Liberty ship sank about three hours after the seacocks were opened.
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.
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 Francop Affair was a high seas incident on November 4, 2009 in which the Israeli Navy seized the cargo ship MV Francop in the eastern Mediterranean Sea and its cargo of hundreds of tons of weapons allegedly bound from Iran to Hezbollah. The incident is also known by its military operation name, Operation Four Species.
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 in conflict. A notable example includes the use of such weapons by the US government that sprayed more than 20 million gallons of various herbicides over Vietnam, Cambodia and Laos from 1961 to 1971. Agent Orange, which contained the deadly chemical dioxin, was the most commonly used herbicide. Other examples of the use of chemical weapons 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 Davy Jones' Locker was a U.K. and U.S. military operation from 1946 to 1948. It involved the dumping at sea of captured German chemical weapons following the end of World War II.
SS El Estero was a ship filled with ammunition that caught fire at dockside in New York Harbor in 1943, but was successfully moved away and sunk by the heroic efforts of tug boats and fireboats, averting a major disaster.
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.
