Baikonur Cosmodrome Site 250

Site 250 at the Baikonur Cosmodrome, also known as UKSS (Russian: Универсальный Комплекс Стенд-Старт, lit. 'Universal Complex Stand-Start') and Bayterek (Russian: Байтерек), is a test facility and launch site which was used by the Energia rocket during the 1980s. The site consists of a single launch pad, which doubled as a test stand, and is supported by an engineering area and a propellant storage facility. As of 2011[update] the complex was planned to be rebuilt as the Bayterek Launch Complex, which would be used by the Angara rocket from 2015; however development is yet to begin.
