Korolev made the decision on 16 Sept 1965 that the L1 would be a single-design spacecraft, capable of being used in either the direct flight or podsadka schemes. At some point thereafter, it seems the version for podsadka was designated L1s (perhaps for L1 stykoviy, L1-docking). (Mishin Diaries 1-178)

All possibilities to improve the accuracy of the landing without the Ye-8 were to be examined. The first N1 missions would rehearse the two-launch scenario, with the Ye-8 being launched by a UR-500K and an L3S (orbital version of the L1S) standing in for the LOK (no LK being available yet).
