Kosmos 869 is a code name for the unmanned flight of the Soviet spaceship Soyuz 7K-S . It was customary in the Soviet Union to give official names only to successful missions. Failed flights were mostly not announced at all and test flights were only announced under the general cover name Kosmos. It was the 41st flight in the Soviet Soyuz program.

Mission overview

This was the third and final test flight of a new Soyuz spacecraft of the type 7K-S. It was intended to serve as a spaceship for solo military missions. At the time of the flight, however, the program had already been discontinued. The completed spaceships were nevertheless launched as unmanned tests under the names Kosmos 670 , Kosmos 772 and Kosmos 869. The experience gained with these flights later flowed into the development of the successor to the Soyuz spaceship 7K-ST.
