TheSoyuz/Vostok, also known as justSoyuz orVostok, or by itsGRAU index,11A510 was an interimexpendablecarrier rocket used by theSoviet Union in 1965 and 1966. Two were launched with prototypeUS-A satellites.[1]
The Soyuz/Vostok was launched fromSite 31/6 at theBaikonur Cosmodrome. It consisted of the first stage and boosters from aSoyuz rocket combined with the second stage of theVostok-2, and an unknown third stage.[1] Along with theVoskhod-derivedPolyot, it was built as an interim between the cancellation of theUR-200 development programme, and the introduction of theTsyklon-2, which took over US-A launches once it entered service.
