E61 anthrax bomblet

Last updated

The E61 anthrax bomblet was an American biological sub-munition for the E133 cluster bomb. This anti-personnel weapon was developed in the early 1950s and carried 35 milliliters of anthrax spores or another pathogen.

History

Around October 1953 the United States Air Force reoriented its biological warfare program. One result of this, in anti-personnel weaponry, was a move away from weapons such as the M33 cluster bomb to the lethal E61 anthrax bomb. [1] The E61 was first developed in January 1951 as both an anti-personnel and anti-animal weapon capable of being clustered and dropped from a medium height. [2] On March 5, 1954, a directive from the U.S. Department of Defense altered the course of the U.S. biological weapons program. [3] The program shifted focus to developing munitions that were not only improved but those that could be delivered by high speed aircraft and balloon. [3] The weapons referred to included the E61 bomblet. [3]

Specifications

The E61 bomblet was a 12-pound (230 g) [3] anti-personnel bomb designed to be carried in the E133 cluster bomb. [4] [5] The cluster bomb was designed to hold about 540 of the E61 anthrax bomblets. [5] [4] The E61 held about 35 milliliters (1.2 U.S. fl oz) of agent [6] and a variety of pathogens could be used, [5] generally anthrax spores. [4] [3] The E61 was perceived as superior to its predecessors, the M33 cluster bomb and its payload of M114 bombs. [6] [2] In fact, four of the smaller E61 bomblets produced twice the coverage area of the larger M114 bomb. [6] Upon impact the E61 would detonate releasing an aerosol of its anthrax spore laden slurry into the air of its target area. [5]

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 :

The E120 bomblet was a biological cluster bomb sub-munition developed to disseminate a liquid biological agent. The E120 was developed by the United States in the early 1960s.

The M143 bomblet was a biological cluster bomb sub-munition developed by the United States during the 1960s. The spherical bomblet was the biological version of the Sarin-filled M139 chemical bomblet.

<span class="mw-page-title-main">M33 cluster bomb</span>

The M33 cluster bomb, also known as the (M33) Brucella cluster bomb, was a U.S. biological cluster bomb developed in the early 1950s and deployed in 1952. It was the first standardized biological weapon in the U.S. arsenal.

<span class="mw-page-title-main">M114 bomb</span>

The M114 bomb was a four-pound U.S. anti-personnel bomb and biological cluster bomb sub-munition. The M114 was used in the M33 cluster bomb.

<span class="mw-page-title-main">Flettner rotor bomblet</span>

The Flettner rotor bomblet was a U.S. biological sub-munition that was never mass-produced. Based on the vertical Flettner rotor which takes advantage of the Magnus effect, a force acting on a spinning body in a moving airstream, it was developed toward the end of the U.S. biological weapons program in the 1960s.

The E77 balloon bomb was a U.S. anti-crop biological munition based on the design of Japanese Fu-Go balloon bomb. The E77 used feathers as a vector to disseminate anti-crop agents from a hydrogen-filled balloon and was first developed in 1950.

<span class="mw-page-title-main">M34 cluster bomb</span>

The M34 cluster bomb was the first mass-produced United States Army weapon meant to deliver the chemical agent sarin (GB). A large stockpile of M34s was destroyed between 1973 and 1976.

The M138 bomblet was a sub-munition of the U.S. chemical weapon, the M43 BZ cluster bomb. The bomblet contained BZ, an incapacitating agent and was developed with the M43 in 1962. The M138s, along with all other U.S. BZ weapons were destroyed during the 1980s.

The E14 munition was a cardboard sub-munition developed by the United States biological weapons program as an anti-crop weapon. In a series of field tests in 1955, the E14 was loaded with fleas and air-dropped.

The E86 cluster bomb was an American biological cluster bomb first developed in 1951. Though the U.S. military intended to procure 6,000 E86s, the program was halted in the first half of the 1950s.

The M125 bomblet was a U.S. chemical sub-munition designed to deliver the nerve agent sarin. It was brought into service in 1954 with the M34 cluster bomb as part of the first U.S. air-delivered nerve agent weapon.

The E133 cluster bomb was a U.S. biological weapon developed during the Cold War.

The E48 particulate bomb was a U.S. biological sub-munition designed during the 1950s for use with the E96 cluster bomb.

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. Although the plant never actually produced bio-weapons before the end of World War II, it did produce 8000 pounds of an anthrax simulant. After the war, the plant was transferred to Pfizer, who operated it until the plants closure in 2008.

M114 or M-114 may refer to:

Before the 20th century, the use of biological agents took three major forms:

Anthrax weaponization is the development and deployment of the bacterium Bacillus anthracis or, more commonly, its spore, as a biological weapon. As a biological weapon, anthrax has been used in biowarfare and bioterrorism since 1914. However, in 1975 the Biological Weapons Convention prohibited the "development, production and stockpiling" of biological weapons. It has since been used in bioterrorism.
