The satellite is designed to identify missile launches using optical telescopes and infrared sensors.[2] Kosmos 1783 was launched from Site 41/1 at Plesetsk Cosmodrome in the Russian SSR.[14] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 13:05 UTC on 3 October 1986.[3] The launch placed the satellite into a molniya orbit but not into a usable orbit due to upper stage failure.[16] It subsequently received its Kosmos designation, and the international designator 1986-075A.[3] The United States Space Command assigned it the Satellite Catalog Number 16993.[3] See also{{Portal|Spaceflight}}
