"program of the USSR Academy of Sciences. In this case, 11S86 (DM) and 11S813 blocks with extended tanks are used as an accelerating stage. 2. Permanent orbital station POS, equipped with modules weighing ~ 23 tons, with a diameter of up to 4.15 m, a length of 20-22 m each, specialized for the purpose: for military tasks, national economic and scientific, but unified for all service purposes systems.
Starting from the end of 1979, they are launched modularly into a synchronous solar orbit at an altitude of 400 km by the RLA-120 launch vehicle, where they are docked. Assuming the rate of construction of the station is one module per year, the complete assembly of the station (five modules) weighing 110-120 tons (with transport modules 150-170 tons) can be completed in 1983. The station begins to function if there are two modules, i.e. since 1980, when the crew size was 3 people. (full strength 6 - 12 people).
The creation of the station corresponds to the developing trend towards increasing the mass of satellites, their integration, increasing their service life and reducing the number of satellites in orbits.
An inhabited permanent station will significantly expand the possibilities for using and studying space.
The station is flexible in its program, repairable, outdated equipment or modules are replaced.
The operation of such a station with a single power supply, communications and other service systems will lead to significant cost savings.
Until the creation of the MTKS, the station's service is provided by disposable three-seat transport spacecraft 7K-ST with the RLA-120 launch vehicle."
