Built in the 1960s for the UR-200, which was first launched from the complex on 3 November 1963,[1] it was converted for use by Tsyklon rockets after further development of the UR-200 was cancelled. One pad is currently active, pending the final Tsyklon-2 launch which is expected to occur in 2012. The two pads at the site are 90/19, which was the first to be used, and 90/20, which saw its first launch in September 1964. The last launch from Site 90/19 occurred on 9 December 1997, whilst 90/20 remains operational, its most recent launch having occurred in June 2006.[2] In total, the complex has been used for 123 launches as of March 2012. These launches consisted of nine UR-200,[3] eight Tsyklon-2A,[4] and 106 Tsyklon-2 rockets.[2] There is no data on which of the two pads was used for 74 of the Tsyklon-2 launches known to have originated from the complex, however it is known that twenty two launches, including six UR-200s and five Tsyklon-2As, occurred from Site 90/19, and 27 launches, including three UR-200s and three Tsyklon-2As, occurred from pad 90/20.[1][2] References1. ^1 {{cite web|url=http://planet4589.org/space/lvdb/launch/UR-200|title=UR-200|work=Orbital and Suborbital Launch Database|first=Jonathan|last=McDowell|accessdate=2 March 2012}} {{Baikonur Cosmodrome launch sites}}2. ^1 2 {{cite web|url=http://planet4589.org/space/lvdb/launch/R-36|title=R-36|work=Orbital and Suborbital Launch Database|first=Jonathan|last=McDowell|accessdate=2 March 2012}} 3. ^{{cite web|url=http://www.astronautix.com/lvs/ur200.htm|title=UR-200|first=Mark|last=Wade|work=Encyclopedia Astronautica|accessdate=2 March 2012}} 4. ^{{cite web|url=http://www.astronautix.com/lvs/tsilon2a.htm|title=Tsiklon-2A|first=Mark|last=Wade|work=Encyclopedia Astronautica|accessdate=2 March 2012}} 1 : Baikonur Cosmodrome |
