Kosmos 2469 was launched from Site 16/2 at Plesetsk Cosmodrome in Russia.[2] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 17:01 UTC on 30 September 2010.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 2010-049A.[3] The United States Space Command assigned it the Satellite Catalog Number 37170.[3]
It was the last launch of a US-K satellite and the last launch of a Molniya-M rocket.[5]
On 15 October 2022, Kosmos 2469 re-entered the atmosphere.[6]
