Another seven Vostok flights (Vostok 7 to 13) were originally planned, going through to April 1966, but these were canceled and the components recycled into the Voskhod program, which was intended to achieve more Soviet firsts in space.
Der var oprindeligt planlagt yderligere syv Vostokflyvninger frem til april 1966, men disse blev aflyst og delene fra dem blev genbrugt i Voskhod-programmet, som var lagt mere an på at opnå flere sovjetiske rekorder i rummet.
