Kosmos 3 (rocket)
The Kosmos-3 (GRAU Index: 11K65, also known as Cosmos-3) was a Soviet carrier rocket (Kosmos (rocket family)), derived from the R-14 missile, which was used to orbit satellites between 1966 and 1968. It was quickly replaced by the modernised Kosmos-3M. Six were flown, four as orbital carrier rockets, and two on sub-orbital flights. All launches occurred from Site 41/15 at the Baikonur Cosmodrome.
