Night Train (test)

Last updated

Operation Night Train was part of a series of chemical and biological warfare tests overseen by the Deseret Test Center as part of Project 112. The test was conducted near Fort Greely, Alaska from November 1963 to January 1964. The primary purpose of Night Train was to study the penetration of an arctic inversion by a biological aerosol cloud. The test's first purpose was to study the downwind travel and diffusion of this cloud when disseminated into different arctic meteorological regimes. [1] All documents about Night Train were considered classified by the Russian military until 2002, when the Department of Defense (DOD) released medically relevant information of all the chemical and biological warfare agent tests conducted under Project 112.

Procedure

A total of 18 biological trials were conducted for Night Train. The trials, meant to study the spread and behavior of biological warfare agents in arctic conditions, were conducted in a temperature range of -39.3° to +3.3° C. In all of these trials, Bacillus subtitles var. niger (also referred to as Bacillus globigii ) was released as a biological warfare simulant, along with fluorescent particles of zinc cadmium sulfide as a tracer material. The trials tested both dry simulant and simulant released from a liquid biological spray tank in order to better investigate the behavior of the simulant in an arctic climate, as the behavior of wet versus dry agents varies based on humidity and other climatic conditions. [3] [4]

Of the 18, a series of 4 surface trials were conducted with dry B. globigii released from the back of a moving and tracked vehicle, accompanied by the release from contractor-flown aircraft of yellow and green fluorescent particles of zinc cadmium sulfide. [3]

The remaining 14 trials involved the aerial release of B. globigii from the A/B45Y-1 liquid biological spray tank, an ejectable and aerodynamic store meant to disseminate and spray a liquid biological agent. [3] [5] The tank was carried on F-105 or F-100 aircraft, and was also accompanied by the release of fluorescent tracer particles. [3]

Controversy and subsequent partial declassification

The declassification of documents pertaining to Night Train and other Project 112 tests began in response to claims that veterans who were exposed to biological agents as a part of Project 112 were falling ill. [6] Although Night Train used only a biological warfare simulant, which is considered harmless to healthy individuals, it has been acknowledged that B. globigii is an organism that can cause illness in those who are immunocompromised. [1] [6]

In order to address health claims, the VA contracted with the National Academy of Sciences to conduct an independent epidemiological study of participants in these tests as compared to veterans who did not participate. [6] However, the VA sponsored study found no evidence that the health of veterans in exposure groups was significantly different from that of veterans who did not participate in the tests. [7]

Approximately 5,500 servicemembers were unknowingly involved in Project 112 tests. [6] Due to pressure from the Department of Veterans Affairs (VA), the DOD began to declassify medically relevant information regarding Night Train and other Project 112 tests that involved the exposure of military personnel to either biological or chemical simulants or active agents, though most of the information remains classified.

A biological agent is a bacterium, virus, protozoan, parasite, fungus, or toxin that can be used purposefully as a weapon in bioterrorism or biological warfare (BW). In addition to these living or replicating pathogens, toxins and biotoxins are also included among the bio-agents. More than 1,200 different kinds of potentially weaponizable bio-agents have been described and studied to date.

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 :

Zinc cadmium sulfide is a mixture of zinc sulfide (ZnS) and cadmium sulfide (CdS). It is used for its fluorescent properties. Bioaccumulation of this chemical may occur along the food chain, for example in plants and in seafood. Long-term or repeated exposures are expected to have harmful effects on the kidneys, bones, and respiratory tract, resulting in kidney impairment, osteoporosis, and chronic inflammation of the respiratory tract.

The Vigo Ordnance Plant, also known as the Vigo Chemical Plant or simply Vigo Plant, was a United States Army facility built in 1942 to produce conventional weapons. In 1944 it was converted to produce biological agents for the U.S. bio-weapons program.

After the war, the plant was transferred to Pfizer, who operated it until the plants closure in 2008.

The Dorset Biological Warfare Experiments were a series of experiments conducted between 1953 and 1975 to determine the extent to which a single ship or aircraft could dispense biological warfare agents over the United Kingdom. The tests between 1971 and 1975 were known as the DICE trials. The tests were conducted by scientists from Porton Down, initially using zinc cadmium sulfide (ZnCds) as a simulated agent. Early results clearly showed that one aircraft flying along the coast while spraying its agent could contaminate a target over 100 miles away, over an area of 10,000 square miles. This method of biological warfare attack and the test program to study it was known as the Large Area Coverage (LAC) concept.

Operation Sea-Spray was a 1950 U.S. Navy secret biological warfare experiment in which Serratia marcescens and Bacillus globigii bacteria were sprayed over the San Francisco Bay Area in California, in order to determine how vulnerable a city like San Francisco may be to a bioweapon attack.
