Kosmos 869 (Russian: Космос 869 meaning Cosmos 869) was an uncrewed military Soyuz 7K-S test. It was a somewhat successful mission. This was the third and final test flight of a new Soyuz spacecraft type 7K-S. It was designed to be a spaceship for military solo missions. At the time of the launch the program had already been discontinued. The completed spaceships were launched as uncrewed test flights: Kosmos 670, Kosmos 772 and Kosmos 869. The experience from these flights were used in the development of the successor program Soyuz spacecraft the Soyuz 7K-ST.[1] [2][3][4][5][6]
