Voskhod rocket

Voskhod (Russian: Восход, lit. 'ascent/dawn', GRAU index: 11A57, Sheldon: A-2, DoD: SL-4) was Soviet medium-lift launch vehicle, a derivative of the R-7, an ICBM. The Voskhod rocket was designed for the human spaceflightprogramme but later used for launching Zenitreconnaissance satellites. It was essentially an 8K78/8K78M minus the Blok L stage and spec-wise was a halfway between the two boosters, with the former's older, lower-spec engines and the latter's improved Blok I design. Its first flight was on 16 November 1963 when it successfully launched a Zenit satellite from LC-1/5 at Baikonur. Boosters used in the Voskhod program had a man-rated version of the RD-0107 engine; this version was known as the RD-0108.
