The Sputnik rocket was an uncrewed orbital carrier rocket designed by Sergei Korolev in the Soviet Union, derived from the R-7 Semyorka ICBM. On 4 October 1957, it was used to perform the world's first satellite launch, placing Sputnik 1 into a low Earth orbit.

Two versions of the Sputnik were built, the Sputnik-PS (GRAU index 8K71PS), which was used to launch Sputnik 1 and later Sputnik 2, and the Sputnik (8A91), which failed to launch a satellite in April 1958, and subsequently launched 3 on 15 May 1958.[1]

A later member of the R-7 family, the Polyot, used the same configuration as the Sputnik rocket, but was constructed from Voskhod components. Because of the similarity, the Polyot was sometimes known as the Sputnik 11A59.
