"The Vostok-2M (Russian: \u0412\u043E\u0441\u0442\u043E\u043A meaning \"East\"), GRAU index 8A92M 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."@en .
