The 921-1 manned capsule entered full scale development in 1993 and the 921-2 space station in 1999.

A Guest Observer program was initiated in February, 1993.

NPO Molniya, Antonov, and TsAGI proposed a spaceplane demonstrator project to the European Space Agency in 1993-1994 under the RADEM project. This would be a scaled-back version of the cancelled MAKS spaceplane using existing rocket engines.
