In 1990 KB Salyut proposed an unmanned derivative of the TKS to conduct zero-gravity materials production experiments. Materials produced by 16 different devices would be returned to earth in small KSI re-entry capsules or in the large main VA capsule at the completion of the mission. The 20 tonne satellite would have a five year life and was to be launched by 1993. The mission would be a preliminary to a full-scale production TMP Skif-DM 90 tonne spacecraft. No backers for the concept were forthcoming.
