Kosmos 1124 was launched from Site 43/4 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 00:17 UTC on 28 August 1979.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1979-077A.[4] The United States Space Command assigned it the Satellite Catalog Number 11509.[4]

It self-destructed on 9 September 1979.[5]

The primary portion of it and several pieces of its debris still remain in orbit.[6]
