The Molniya, GRAU Index 8K78, was a modification of the well-known R-7 Semyorka rocket and had four stages. The rocket was given the name Molniya due to the large number of Molniya communication satellites the rockets launched.

The R-7 Semyorka, officially the GRAU index 8K71, was a Soviet missile developed during the Cold War, and the world's first intercontinental ballistic missile. The R-7 made 28 launches between 1957 and 1961. A derivative, the R-7A, was operational from 1960 to 1968. To the West it was unknown until its launch. In modified form, it launched Sputnik 1, the first artificial satellite, into orbit, and became the basis for the R-7 family which includes Sputnik, Luna, Molniya, Vostok, and Voskhod space launchers, as well as later Soyuz variants. Various modifications are still in use and it has become the world’s most reliable space launcher.
