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]
