MKNAOMI was the code name for a joint Department of Defense/CIA research program lasting from the 1950s through the 1970s. Unclassified information about the MKNAOMI program and the related Special Operations Division is scarce. It is generally reported to be a successor to the MKDELTA project and to have focused on biological projects including biological warfare agents—specifically, to store materials that could either incapacitate or kill a test subject and to develop devices for the diffusion of such materials.
