Kosmos 606 (Russian: Космос 606 or Cosmos 606) was a Soviet US-K missile early warning satellite which was launched in 1973 as part of the Soviet military's Oko programme. The satellite was designed to identify missile launches using optical telescopes and infrared sensors.[2]


Kosmos 606 was launched from Site 41/1 at Plesetsk Cosmodrome in the Russian SSR.[3] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 13:01 UTC on 2 November 1973.[3]


The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1973-084A .[4] The United States Space Command assigned it the Satellite Catalog Number 6916.[4]
