[edit on Wikidata]

TheSoyuz/Vostok (GRAU index:11A510) was an interimexpendable carrier 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 boosters (first stage) and second stage (core) from aSoyuz rocket combined with the third stage of theVostok-2, and an unknown fourth 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.
