The Soyuz/Vostok was launched from Site 31/6 at the Baikonur Cosmodrome. It consisted of the first stage and boosters from a Soyuz rocket combined with the second stage of the Vostok-2, and an unknown third stage.[1] Along with the Voskhod-derived Polyot, it was built as an interim between the cancellation of the UR-200 development programme, and the introduction of the Tsyklon-2, which took over US-A launches once it entered service.
