The Voskhod rocket (Russian: Восход, translated as "Sunrise") was a derivative of the Soviet R-7 ICBM designed for the human spaceflightprogramme but later used for launching Zenit reconnaissance satellites. It combined the R-7 with an upper stage that had been originally designed to launch interplanetary probes.
There was only one main variant of the Voskhod, designated 11A57. Between 1963 and 1976 it was used for some 300 launches.

The lack of space also meant that the Voskhod crews did not wear space suits, although one was taken on the Voshkod 2 mission.
Finally, the Voskhod 2 spacecraft carried a large inflatable airlock that allowed cosmonaut Aleksei Leonov to exit and re-enter the craft.
Voskhod was carried into orbit by a variant of the same R-7 rocket that was used for Vostok and Sputnik, but featured a larger upper stage to carry the heavier capsule.
