United States biological weapons program

The United States biological weapons program officially began in spring 1943 on orders from U.S. President Franklin Roosevelt. Research continued following World War II as the U.S. built up a large stockpile of biological agents and weapons. Over the course of its 27 year history, the program weaponized and stockpiled the following seven bio-agents (and pursued basic research on many more):

Throughout its history, the U.S. bioweapons program was secret. It became controversial when it was later revealed that laboratory and field testing (some of the latter using simulants on non-consenting individuals) had been common. The official policy of the United States was first to deter the use of bio-weapons against U.S. forces and secondarily to retaliate if deterrence failed. There exists no evidence that the U.S. ever used biological agents against an enemy in the field (see below for alleged uses).

In 1969, President Richard Nixon ended all offensive (i.e., non-defensive) aspects of the U.S. bio-weapons program. In 1975 the U.S. ratified both the 1925 Geneva Protocol and the 1972 Biological Weapons Convention (BWC)—international treaties outlawing biological warfare. Recent U.S. biodefense programs, however, have raised concerns that the U.S. may be pursuing research that is outlawed by the BWC.

Early history (1918-41)

The United States' first interest in any form of biological warfare came at the close of World War I. The only agent the U.S. tested was the toxin ricin a product of the castor plant.[1] The U.S. conducted tests concerning two methods of ricin dissemination, the first, involved adhering the toxin to shrapnel for delivery by artillery shell, which was successful.[1] The other method, delivering an aerosol cloud of ricin, proved less successful.[1] Neither delivery method was perfected before the war in Europe ended.[1]

In the early 1920s suggestions that the U.S. began a biological weapons program were coming from within the Chemical Warfare Service (CWS).[1] Chief of the CWS, Amos Fries, decided that such a program would not be "profitable" for the U.S.[1] Japan's Shiro Ishii began promoting biological weapons during the 1920s and toured biological research facilities worldwide, including in the United States.[1] Though Ishii concluded that the U.S. was developing a bio-weapons programs, he was incorrect.[1] In fact, Ishii concluded that each major power he visited was developing a bio-weapons program.[1] As the interwar period continued, the United States did not emphasize biological weapons development or research.[1] While the U.S. was spending very little time on biological weapons research, its future allies and enemies in the upcoming second World War were researching the potential of biological weapons as early as 1933.[1]

World War II (1941-45)

Despite the World War I-era interest in ricin, as World War II erupted, the United States Army still maintained the position that biological weapons were, for the most part, impractical.[2] Other nations, notably France, Japan and the United Kingdom, thought otherwise and had begun their own biological weapons programs.[2] Thus, as late as 1942 the U.S. had no biological weapons capabilities. Initial interest in biological weapons by the Chemical Warfare Service began in 1941.[3] That fall, U.S. Secretary of War Henry L. Stimson requested that the National Academy of Sciences (NAS) undertake consideration of U.S. biological warfare.[4] He wrote to Dr. Frank B. Jewett, then president of the NAS:

Because of the dangers that might confront this country from potential enemies employing what may be broadly described as biological warfare, it seems advisable that investigations be initiated to survey the present situation and the future possibilities. I am therefore, asking if you will undertake the appointment of an appropriate committee to survey all phases of this matter. Your organization already has before it a request from The Surgeon General for the appointment of a committee by the Division of Medical Sciences of the National Research Council to examine one phase of the matter.[5]

In response the NAS formed a committee, the War Bureau of Consultants (WBC), which issued a report on the subject in February 1942.[4] The report, among other items, recommended the research and development of an offensive biological weapons program.[4]

The British, and the research undertaken by the WBC, pressured the U.S. to begin biological weapons research and development and in November 1942 U.S. President Franklin Roosevelt officially approved an American biological weapons program.[6] In response to the information provided by the WBC, Roosevelt ordered Stimson to form the War Research Service (WRS).[4][7] Established within the Federal Security Agency, the WRS' stated purpose was to promote "public security and health",[7] but, in reality, the WRS was tasked with coordinating and supervising the U.S. biological warfare program.[4] In the spring of 1943 the U.S. Army Biological Warfare Laboratories were established at Fort (then Camp) Detrick in Maryland.[6][8]

[64], U.S. work on non-lethal agents exceeds limitations in the BWC.Federation of American ScientistsAccording to the

[65] That law defined a biological agent as:[65].Biological Weapons Anti-Terrorism Act of 1989 Previous interpretation was stated to be in line with a definition laid out in Public Law 101-298, the [64] For example, it is said that the U.S. now maintains that the Article I of the BWC (which explicitly bans bio-weapons), does not apply to "non-lethal" biological agents.[64]In recent years certain critics have claimed the U.S. stance on biological warfare and the use of biological agents has differed from historical interpretations of the BWC.

After Nixon declared an end to the U.S. bio-weapons program, debate in the Army centered around whether or not toxin weapons were included in the president's declaration.[21] Following Nixon's November 1969 order, scientists at Fort Detrick worked on one toxin, Staphylococcus enterotoxin type B (SEB), for several more months.[21] Nixon ended the debate when he added toxins to the bio-weapons ban in February 1970.[19] The U.S. also ran a series of experiments with anthrax, code named Project Bacchus, Project Clear Vision and Project Jefferson in the late 1990s and early 2000s.

Both the U.S. bio-weapons ban and the Biological Weapons Convention restricted any work in the area of biological warfare to defensive in nature. In reality, this gives BWC member-states wide latitude to conduct biological weapons research because the BWC contains no provisions for monitoring of enforcement.[62][63] The treaty, essentially, is a gentlemen's agreement amongst members backed by the long-prevailing thought that biological warfare should not be used in battle.[62]

Current (post-1969) bio-defense program

The GAO scolded the U.S. Department of Defense's (DOD) 2003 decision to stop searching for people affected by the tests was premature.[56] The GAO report also found that the DoD made no effort to inform civilians of exposure, and that the United States Department of Veterans Affairs (VA) is failing to use available resources to inform veterans of possible exposure or to determine if they were deceased. After the DoD halted efforts to find those who may have been affected by the tests, veteran health activisits and others identified approximately 600 additional individuals who were potentially exposed during Project 112.[59] Some of the individuals were identified after the GAO reviewed records stored at the Dugway Proving Ground, others were identified by the Institute of Medicine.[60] Many of the newly identified suffer from long term illnesses that may have been caused by the biological or chemical testing.[61]

In February, 2008, the Government Accountability Office (GAO) released report GAO-08-366 titled, "Chemical and Biological Defense, DOD and VA Need to Improve Efforts to Identify and Notify Individuals Potentially Exposed during Chemical and Biological Tests." The report stated that tens of thousands of military personnel and civilians may have been exposed to biological and chemical substances through DOD tests. In 2003, the DOD reported it had identified 5,842 military personnel and estimated 350 civilians as being potentially exposed during the testing, known as Project 112.[59]

GAO Report

A jet aircraft released material over Victoria, Texas, that was monitored in the Florida Keys.[57]

Scientists tested biological pathogens, including Bacillus globigii, which were thought to be harmless, at public places such as subways. A light bulb containing Bacillus globigii was dropped on New York City's subway system; the result was strong enough to affect people prone to illness (also known as Subway Experiment).[58] Based on the circulation measurements, thousands of people would have been killed if a dangerous microbe was released in the same manner.[57]

Medical experiments were conducted on a large scale on civilians who had not consented to participate. Often, these experiments took place in urban areas in order to test dispersion methods. Questions were raised about detrimental health effects after experiments in San Francisco, California, were followed by a spike in hospital visits; however, in 1977 the Centers for Disease Control and Prevention determined that there was no association between the testing and the occurrence of pneumonia or influenza.[57] The San Francisco test involved a U.S. Navy ship that sprayed Serratia marcescens from the bay; it traveled more than 30 miles.[57] One dispersion test involved laboratory personnel disguised as passengers spraying harmless bacteria in Washington National Airport.[57]

In civilian venues

The U.S. military acknowledges that it tested several chemical and biological weapons on US military personnel in the desert facility, including the East Demilitarization Area near Deseret Chemical Depot/Deseret Chemical Test Center at Fort Douglas, Utah, but takes the position that the tests have contributed to long-term illnesses in only a handful of exposed personnel.[56] Veterans who took part believe they were also exposed to Agent Orange. The Department of Veterans Affairs denies almost all claims for care and compensation made by veterans who believe they got sick as a result of the tests. The U.S. military for decades remained silent about "Project 112" and its victims, a slew of tests overseen by the Army's Deseret Test Center in Salt Lake City. Project 112 starting in the 1960s tested chemical and biological agents, including VX, sarin and E. coli, on military personnel who did not know they were being tested. After the Defense Department finally acknowledged conducting the tests on unwitting human subjects, it agreed to help the Veterans' Affairs Department track down those who were exposed, but a General Accountability Office report in 2008 scolded the military for ceasing the effort.[56]

In August 1949 a U.S. Army Special Operations Division, operating out of Fort Detrick in Maryland, set up its first test at The Pentagon in Washington, D.C. Operatives sprayed harmless bacteria into the building's air conditioning system and observed as the microbes spread throughout the Pentagon.[55]

Operation Whitecoat involved the controlled testing of many serious agents on military personnel consented to experimentation, and understood the risks involved. No deaths are known to have resulted from this program.

Entomological testing

Experimentation and testing

Accusations have continued to come out of Havana charging U.S. use of bio-weapons on the island. The Cuban government blamed the U.S. for a 1981 outbreak of dengue fever that sickened more than 300,000.[48] Dengue, a vector-borne disease usually carried by mosquitoes,[50] killed 158 people that year in Cuba, including 101 children under 15.[48] Tensions between the two countries, coupled with confirmed U.S. research into entomological warfare during the 1950s, made these charges seem not implausible to some people.[48][50] However, dengue fever occurs naturally in the Caribbean basin[48] and the dengue virus is not considered a weaponizable "biological threat agent" or select agent by international authorities attempting to control bio-weapons.

It has been rumored that the U.S. employed biological weapons against the Communist island nation of Cuba. Noam Chomsky claimed that evidence exists implicating the U.S. in biological warfare in Cuba,[47] but his evidence was disputed.[48][49] Allegations in 1962 held that CIA operatives had contaminated a shipment of sugar while it was in storage in Cuba.[50] Again, in 1962, a Canadian agricultural technician assisting the Cuban government claimed he was paid $5,000 to infect Cuban turkeys with the deadly Newcastle disease.[50][51] Though the technician later claimed he had just pocketed the money, many Cubans and some Americans believed a clandestinely administered biological weapons agent was responsible for a subsequent outbreak of the disease in Cuban turkeys.[50] In 1971 the first serious outbreak of swine flu in the Western Hemisphere occurred in Cuba, and Cubans alleged that U.S. covert biological warfare was responsible for this outbreak, which led to the preemptive slaughter of 500,000 pigs.[48] Evidence linking these incidents to biological warfare has not been confirmed.[48]


In March 2010, the allegations were investigated by the Al Jazeera English news program People & Power.[46] In this program, Professor Mori Masataka investigated historical artifacts in the form of bomb casings from US biological weapons, contemporary documentary evidence and eyewitness testimonies.[46] He concluded that the United States did, in fact, test biological weapons on North Korea during the Korean War.[46]

In 1998, Stephen Endicott and Edward Hagermann claimed that the accusations were true in their book, The United States and Biological Warfare: Secrets from the Early Cold War and Korea[42] The book received mixed reviews, some calling it "bad history"[43] and "appalling",[38] while others praised the authors' case.[43] In the same year Endicott's book was published, Kathryn Weathersby and Milton Leitenberg of the Cold War International History Project at the Woodrow Wilson Center in Washington released a cache of Soviet and Chinese documents that revealed the North Korean claim to have been an elaborate disinformation campaign.[40][44] In addition, a Japanese journalist claims to have seen similar evidence of a Soviet disinformation campaign and that the evidence supporting its occurrence was faked.[39] In 2001, KGB historian Herbert Romerstein supported Weathersby and Leitenberg, observing that Endicott's researches were purely based on accounts provided by the Chinese government.[45]

In 1952, during the World Peace Council.[39] A committee led by Joseph Needham gathered evidence for a report that included testimony from eyewitnesses, doctors, and four American Korean War prisoners who confirmed use of biological weapons by the U.S.[39] The U.S. government denied the accusations and their denial was generally supported by top scientists in the West.[39] In eastern Europe, China, and North Korea it was widely believed that the accusations were true.[37] A 1988 book on the Korean War, by Western historians Jon Halliday and Bruce Cumings also suggested the claims might be true.[40][41]

Korean War

[There was] ... a history of dozens of allegations made by various branches of the Soviet government for the entire post-World War II period charging that the United States had used biological weapons. As best as is known, all of these allegations are deliberate, fraudulent concoctions. The most notorious of these were the allegations made by the Soviet Union, the People's Republic of China, and North Korea, charging that the United States used biological weapons during the 1950-1953 Korean War. There was a brief respite from these charges between 1987 and 1992, but after that former Soviet military officials who were part of the Soviet Union's own BW program once again began to repeat the same discredited charges.[36]

Alleged uses

Work on delivery systems for the U.S. bioweapons arsenal led to the first mass-produced biological weapon in 1952, the William C. Patrick III.[35]

A U.S. facility at Fort Terry focused primarily on anti-animal biological agents. The first agent that was a candidate for development was foot and mouth disease (FMD).[14] Besides FMD, five other top-secret biological weapons projects were commissioned on Plum Island.[30] The other four programs researched included RVF, rinderpest, African swine fever, plus eleven miscellaneous exotic animal diseases.[14][30] The eleven miscellaneous pathogens were: Blue tongue virus, bovine influenza, bovine virus diarrhea (BVD), fowl plague, goat pneumonitis, mycobacteria, "N" virus, Newcastle disease, sheep pox, Teschers disease, and vesicular stomatitis.[14]

Besides the numerous pathogens that afflict human beings, the U.S. had developed an arsenal of anti-agriculture biological agents. These included rye stem rust spores (stored at Edgewood Arsenal, 1951–1957), wheat stem rust spores (stored at the same facility 1962–1969),[11] and the causative agent of rice blast (stored at Fort Detrick 1965–1966).[11]

When the U.S. biological warfare program ended in 1969 it had developed seven mass-produced, battle-ready biological weapons in the form of agents that cause: anthrax, tularemia, brucellosis, Q-fever, VEE, and botulism.[10] In addition staphylococcal enterotoxin B was produced as an incapacitating agent.[10] In addition to the agents that were ready to be used, the U.S. program conducted research into the weaponization of more than 20 other agents. They included: smallpox, EEE and WEE, AHF, Hantavirus, BHF, Lassa fever, glanders,[28] melioidosis,[28] plague, yellow fever, psittacosis, typhus, dengue fever, Rift Valley fever (RVF), CHIKV, late blight of potato, rinderpest, Newcastle disease, bird flu, and the toxin ricin.[29]

Agents studied and weaponized

When Nixon ended the U.S. bio-weapons program in 1969 he also announced that he would resubmit the Geneva Protocol to the U.S. Senate.[21] This was a move Nixon was considering as early as July 1969.[21] The announcement included language that indicated the Nixon administration was moving toward an international agreement on an outright ban on bio-weapons.[21] Thus, the Nixon administration became the world's leading anti-biological weapons voice calling for an international treaty.[17] The Eighteen Nation Disarmament Committee was discussing a British draft of a biological weapons treaty which the United Nations General Assembly approved in 1968 and that NATO supported.[19] These arms control talks would eventually lead to the Biological Weapons Convention, the international treaty outlawing biological warfare.[26] Prior to the Nixon announcement only Canada supported the British draft.[21] Beginning in 1972, the Soviet Union, United States and more than 100 other countries signed the BWC.[17] The United States ratified the Geneva Protocol in 1975.[27]

The 1925 Geneva Protocol, ratified by most major powers in the 1920s and 30s, had still not been ratified by the United States at the dawn of World War II.[18] Among the Protocol's provisions was a ban on bacteriological warfare.[25] The Geneva Protocol had encountered opposition in the U.S. Senate, in part due to strong lobbying against it by the Chemical Warfare Service, and it was never brought to the floor for a vote when originally introduced.[18] Regardless, on June 8, 1943 President Roosevelt affirmed a no-first-use policy for the United States concerning biological weapons.[18][25] Even with Roosevelt's declaration opposition to the Protocol remained strong; in 1949 the Protocol was among several old treaties returned to President Harry S. Truman unratified.[18]

Geneva Protocol and BWC

From the onset of the U.S. biological weapons program in 1943 through the end of World War II the United States spent $400 million on biological weapons, mostly on research and development.[23] The budget for fiscal year 1966 was $38 million.[24] When Nixon ended the U.S. bio-weapons program it represented the first review of the U.S. biological warfare program since 1954.[19] Despite the lack of review, the biological warfare program had increased in cost and size since 1961; when Nixon ended the program the budget was $300 million annually.[19][20]

Budget history

U.S. biological weapons stocks were destroyed over the next few years. A $12 million disposal plan was undertaken at Pine Bluff Arsenal,[22] where all U.S. anti-personnel biological agents were stored.[21] That plan was completed in May 1972 and included decontamination of facilities at Pine Bluff.[21][22] Other agents, including anti-crop agents such as wheat stem rust, were stored at Beale Air Force Base and Rocky Mountain Arsenal.[21] These anti-crop agents, along with agents at Fort Detrick used for research purposes were destroyed in March 1973.[21]

In his speech Nixon called his move "unprecedented"; and it was in fact the first review of the U.S. biological warfare program since 1954.[19] Despite the lack of review, the biological warfare program had increased in cost and size since 1961; when Nixon ended the program the budget was $300 million annually.[19][20] Nixon's statement confined all biological weapons research to defensive-only and ordered the destruction of the existing U.S. biological arsenal.[21]

The United States shall renounce the use of lethal biological agents and weapons, and all other methods of biological warfare. The United States will confine its biological research to defensive measures such as immunization and safety measures.

Nixon President

End of the program (1969-73)

Subsequently, Nixon announced that the U.S. was unilaterally renouncing its biological warfare program.[15]

Another substantive expansion phase was during the Kennedy-Johnson years, after McNamara initiated Project 112 as a comprehensive initiative, starting in 1961. Despite an increase in testing, the readiness for biological warfare remained limited after this program. A 10 November 1969 report by the Interdepartmental Political-Military Group submitted its findings to the Nixon administration that the American BW capability was limited:[15][16]

The U.S. biological program expanded significantly during the Korean War.[13] From 1952-1954 the Chemical Corps maintained a biological weapons research and development facility at Fort Terry on Plum Island, New York.[14] The Fort Terry facility's focus was on anti-animal biological weapon research and development; the facility researched more than a dozen potential BW agents.[14] A facility was opened in Pine Bluff, Arkansas, Pine Bluff Arsenal and by 1954 the production of weapons-grade agents began.[13]

Immediately following World War II, production of U.S. biological warfare agents went from "factory-level to laboratory-level".[10] Meanwhile, work on biological weapons delivery systems increased.[10] By 1950 the principal U.S. bio-weapons facility was located at Camp Detrick in Maryland under the auspices of the Research and Engineering Division of the U.S. Army Chemical Corps.[11] The U.S. also maintained bio-warfare facilities at Fort Terry, an animal research facility on Plum Island.[12] From the end of World War II through the Korean War, the U.S. Army, the Chemical Corps and the U.S. Air Force all made great strides in their biological warfare programs, especially concerning delivery systems.[10]
