Kosmos 2222 was launched from Site 43/3 at Plesetsk Cosmodrome in Russia.[5] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 12:18 UTC on 25 November 1992.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1992-081A.[3] The United States Space Command assigned it the Satellite Catalog Number 22238.[3]

The satellite became inactive in 1995, and reentered the Earth's atmosphere on 3 May 2023 at 03:58 UTC.[6]
