Yubileyniy Airfield, designated ICAO code UAON, is a military and technical airfield located near Töretam in southern Kazakhstan, in close proximity to the Baikonur Cosmodrome. The facility is associated with Soviet and Russian space program logistics, having been used to transport large aerospace components and equipment to the cosmodrome. The airfield is not a commercial passenger airport and has no scheduled civilian airline services. It was developed to support the space and defense infrastructure of the Baikonur complex, which has historically been leased by Russia from Kazakhstan. Its runways were designed to accommodate heavy transport aircraft capable of carrying oversized cargo related to space launch operations.
