Vostok-2M was an expendable carrier rocket used by the Soviet Union between 1964 and 1991. Ninety-three were launched, of which one failed. Another was destroyed before launch. It was originally built as a specialised version of the earlier Vostok-2, for injecting lighter payloads into higher Sun-synchronous orbits. It was a member of the R-7 family of rockets, and the last Vostok.
