The '''Polyot''' ({{langx|ru|Полёт}}, ''flight'') (Also known as Sputnik, [[GRAU]] index 11A59) was an interim [[orbit]]al [[carrier rocket]], built to test [[Anti-satellite weapon|ASAT]] spacecraft. It was required as a stopgap after the cancellation of the [[UR-200]] programme, but before the [[Tsyklon]] could enter service. Only two were ever launched, the first on 1 November 1963, and the last on 12 April 1964. Both of these flights were successful.

The rocket consisted of a core stage, and four boosters, which were taken from a [[Voskhod (rocket)|Voskhod 11A57]] rocket. It was capable of delivering a 1,400&nbsp;[[kilogram|kg]] payload into a 300&nbsp;km by 59° [[Low Earth orbit]].

It is a member of the [[R-7 (rocket family)|R-7 family]].
