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.

==History==
The E120 bomblet was one of several biological weapons that were developed before the United States abandoned its offensive biological warfare program in 1969–1970.<ref name=eitzen>Eitzen, Edward M.

==Specifications==
The E120 was a spherical bomblet with a diameter of 11.4 centimeters.<ref name=countermeasures/> It was designed to hold 0.1 kilograms of liquid biological agent. Much like the [[M139 bomblet]], the E120 had exterior "vanes". However, the vanes' function on the E120 was to cause the bomblet to rotate as it fell, thus shattering and rolling around upon impact while spraying the agent from a nozzle.<ref name=countermeasures>''Countermeasures'', [http://www.ciar.org/ttk/mbt/missile-countermeasures-technology.CM_ch6-9.pdf Chapter 6 - An Overview of Emerging Missile State Countermeasures], p. 14, accessed November 12, 2008.</ref>
