 | | It was the Soviet Union's first spy satellite, and its later versions remained in use into the 21st Century. |
 | | The agreed technical specifications for the 2K satellite (given the code name Zenit-2) were for a photo apparatus with a focal length of not less than a meter, limited only by the size of the spacecraft itself. |
 | | The first Zenits were fitted out with the SA-20 camera, with a focal length of 1 meter, the SA-10 camera, with a focal length of 0.2 m, the Baikal photo-television device, and the Kust-12M ELINT radio apparatus (developed by M E Zaslavskiy). |
