The Voskhod rocket (Russian: Восход, "ascent", "dawn") was a derivative of the Soviet R-7 ICBM designed for the human spaceflight programme but later used for launching Zenit reconnaissance satellites.[1][2] 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.[3]

Starting in 1966, the 11A57 adopted the standardized 11A511 core with the more powerful 8D74M first stage engines, however the Blok I stage continued using the RD-0107 engine rather than the RD-0110. Around 300 were flown from Baikonur and Plesetsk through 1976, almost all of them used to launch Zenit reconnaissance satellites (one exception was the Intercosmos 6 satellite in 1973).

The newer 11A511U core had been introduced in 1973, but the existing stock of 11A57s took another three years to use up.

The rocket had a streak of 86 consecutive successful launches between 11 September 1967 and 9 July 1970.
