Kosmos 1849 was launched from Site 16/2 at Plesetsk Cosmodrome in the Russian SSR. A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 18:50 UTC on 4 June 1987. The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1987-048A. The United States Space Command assigned it the Satellite Catalog Number 18083.
