It was accepted into the military in 1968 as part of the 'Raduga' complex. Used until 1978, a total of 78 launches with Kosmos-2 launch vehicles. Colonel Ye S Shchapov was in charge of Raduga development for the military.

Measurements of the sun; used for Interkosmos launches. Design work began in April 1967. Adaptation of DS satellites by KB Yuzhnoye. For the Interkosmos modifications V F Chutkin was Chief Designer and First Assistant was V S Budnik. Interkosmos-1 was launched by a Kosmos-2 launch vehicle in October 1969. Payload included East European experiments to study solar UV, X-ray effects on upper atmosphere. Investigation of solar radiation and its effect on the atmosphere of the earth.
|Spacecraft: DS-P1-M. |
Target for development of ASAT systems. A lighter target that could be launched by the smaller Kosmos rocket replaced the first R-36 launched IS-P target. Developed by KB Yuzhnoye (KB-3 Section; Chief Designer V M Kovtunenko). Although it acted as a target for the IS anti-satellite system, it was designed for both anti-ballistic missile and anti-satellite testing. It was more than a passive target, including an impact registration system and elements of the hit (direction, velocity, etc.). First flight trials were in August 1970. It was in service from 1973 to 1983, at which time the Soviet Union unilaterally abandoned anti-satellite operations.
