The DOS station was built on basis of first three Almaz to determine the usefulness of manned observation of the earth within 4 to 5 years.

Brezhnev orders a cooperative crash program to build a civilian space station to beat Skylab into orbit. The civilian station (later named Salyut) will use the Almaz spaceframe fitted out with Soyuz functional equipment. Mishin's OIS military station was cancelled and Chelomei's Almaz would continue, but as second priority to the civilian station. The Soyuz 7K-S station ferry, the 7K-ST, would be revised to be a more conservative modification of the Soyuz 7K-OK. The OIS cosmonaut group was incorporated into the Almaz group.
