English: Cosmos 389 ELINT by Brian W. McMullin, 1982: This 1982 work shows the Cosmos 389 satellite, which was launched in December 1970 and performed electronic intelligence (ELINT) missions. Cosmos 389 was the first in a series of "ferret" satellites that pinpointed sources of radar and radio emissions to identify air defense sites and command and control centers. Transmitted to ground stations, the data was used for Soviet targeting and war planning.
