Soyuz Kontakt P
Provisional drawing of Soyuz Kontakt P (Passive) derivative of Soyuz for earth orbit tests of Kontakt lunar orbit docking system. It is uncertain if the Soyuz included the forward-mounted maneuvering engines, or just the passive docking mechansim of the LK lunar lander. Certainly the LK's forward viewing port and docking optical device would have to be included in the orbital module. It is not known if the downward-looking viewport and extensive scallop of the LK cabin was a feature.
