Site 200 at the Baikonur Cosmodrome is a launch site used by Proton rockets. It consists of two launch pads, areas 39 and 40. Area 39 is currently used for Proton-M launches, including commercial flights conducted by International Launch Services. Area 40 is currently inactive, as it was slated to be rebuilt as a launch site for the Angara rocket. Although the project was relocated to Site 250, Area 40 was not put back into service.
