The Ministry of Medium Machine Building was tasked with managing the Soviet nuclear program, which included the creation of nuclear warheads. Although scientists were needed for research and development, the facilities where the arsenals were located were military installations. One such site was this one in Krasnokamianka. The weapons were not manufactured here, but they were assembled and stockpiled on site, held in readiness in case they were needed.
