Class: Manned. Type: Space Station. Nation: USSR. Manufacturer: NPO Energia.

Development of a new kind of Soviet space station module, designated 37K, was authorised on 17 September 1979. The basic 37K design consisted of a 4.2 m diameter pressurised cylinder with a docking port at the forward end. It was not equipped with its own propulsion system. The original authorisation was for a total of eight 37K's of various configurations.

Production of the four 37KS modules was approved following review of the draft projects on 11 February 1981. The four modules would be placed into orbit by a Proton launch vehicle. The FGO tug section, connected to the 37KS module by a light lattice structure, would rendezvous with the Mir station and dock the module to one of the radial ports of the Mir station. It would then separate and deorbit itself into the earth's atmosphere. Each of the four modules had a different mission:

The plan was that production of all of the modules would be completed in 1984. They would be assembled with the Mir base block in one year and have an operational lifetime of five years. Design and fabrication reached an advanced phase (serial numbers 167 to 170 seem to have been allocated to the FGO tug vehicles) when it was decided that the separate tug concept resulted in too low a net scientific payload (3 tonnes). Integrating the tug with the module was expected to increase this to 5 tonnes and provide some reserve engine capability at Mir and additional pressurised volume. Accordingly the 37KS modules for Mir were cancelled in 1983. Work on the 37KE experimental module (Kvant) and the 37KB Buran modules continued. The function of the 37KS modules was taken up by modules by KB Salyut derived from the FGB. A competing proposal from NPO Energia for a unified spacecraft that combined the 37KS module with the engine unit of Mir was rejected.

37KS Chronology


17 September 1979 37K space station module authorised

The basic 37K design consisted of a 4.2 m diameter pressurised cylinder with a docking port at the forward end. It was not equipped with its own propulsion system. The original authorisation was for a total of eight 37K's of various configurations. Of these, only the 37K-E (Kvant module of Mir) and the 37KS (instrumentation module in Buran) would fly.


11 February 1981 Production of the Production of four 37KS modules for Mir approved

Production of the four 37KS modules was approved following review of the draft projects. The four modules would be placed into orbit by a Proton launch vehicle. An FGO tug section, connected to the 37KS module by a light lattice structure, would rendezvous with the Mir station and dock the module to one of the radial ports of the Mir station. It would then separate and deorbit itself into the earth's atmosphere. The plan was that production of all of the modules would be completed in 1984. They would be assembled with the Mir base block in one year and have an operational lifetime of five years.


01 November 1983 37KS Modules for Mir cancelled, replaced by FGB modules.

Design and fabrication reached an advanced phase when it was decided that the separate tug concept resulted in too low a net scientific payload (3 tonnes). Integrating the tug with the module was expected to increase this to 5 tonnes and provide some reserve engine capability at Mir and additional pressurised volume. Accordingly the 37KS modules for Mir were cancelled. Work on the 37KE experimental module (Kvant) and the 37KB Buran modules continued. The function of the 37KS modules was taken up by modules by KB Salyut derived from the FGB. A competing proposal from NPO Energia for a unified spacecraft that combined the 37KS module with the engine unit of Mir was rejected.
