Kosmos 1774 (Russian: Космос 1774 meaning Cosmos 1774) was a Soviet US-K missile early warning satellite launched in 1986 as part of the Soviet military's Oko programme. The satellite is designed to identify missile launches using optical telescopes and infrared sensors.^[2]

Kosmos 1774 was launched from Site 16/2 at Plesetsk Cosmodrome in the Russian SSR.^[5] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 08:02 UTC on 28 August 1986.^[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1986-065A.^[3] The United States Space Command assigned it the Satellite Catalog Number 16922.^[3]

It re-entered the Earth's atmosphere on 2 November 2010.^[4]
