During the first twenty years of its establishment, the CIA engaged in various projects designed to increase U.S. biological and chemical warfare capabilities. Project MKNAOMI was initiated to provide the CIA with a covert support base to meet its top-secret operational requirements. The purpose was to establish a robust arsenal within the CIA's Technical Services Division (TSD) and of which was to consist of various lethal and incapacitating materials. This would enable the TSD to serve as a highly maintained center for the circulation of biological and chemical materials. [citation needed]
