Kosmos 1729 was launched from Site 16/2 at Plesetsk Cosmodrome in the Russian SSR.[5] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 18:11 UTC on 1 February 1986.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1986-011A.[3] The United States Space Command assigned it the Satellite Catalog Number 16527.[3]
