Of course, the Semyorka for Sputnics 1,2 and 3 had no upper stage;remember? It was a stage and a half launcher.


And it was just called the Semyorka or Sputnik booster, as it was never
used for anything like that again. The role of small satellite launching
was taken over by the SS-4 "Sandal" derived B-1 small Cosmos launch
vehicle in combination with the SS-5 "Skean" derived C-1 large Cosmos
launch vehicle. The B-1 can put 1,000 pounds into LEO, the C-1 can put
3,400 pounds into orbit. That gave the C-1 around the same payload as
the basic R-7 without upper stages at considerably lower launch cost per
mission.
