The R -9 ( NATO reporting name SS -8 Sasin, GREY index 8K75 ) was a Soviet intercontinental ballistic missile from the Cold War.
The first test flight of the two-stage rocket took place in 1961. Both stages, which were connected with a lattice structure used in liquid oxygen and the Kerosinart RP -1 fuel. The commissioning began in 1964. The last missile was decommissioned in 1976.
Mistakenly, NATO reporting name was SS -8 Sasin also assigned to the R -26, of which 1964 dummy was shown at a military parade. When the error was noticed, the R-26 program was, however, already set, so no new naming took place.
