Baikonur Cosmodrome Site 250

Site 250 at the Baikonur Cosmodrome, also known as UKSS (Russian: Универсальный Комплекс Стенд-Старт, 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 the complex is scheduled to be rebuilt as the Bayterek Launch Complex, which will be used by the Angara rocket from 2015, however development is yet to begin.
