The Soyuz launcher integration building handles launcher integration and checkout of the assembled three-stage basic vehicle. Launcher stages are delivered via a rear receiving dock, and vehicle assembly is performed inside the integration building’s air conditioned main bay.
The launcher’s assembly is performed horizontally, following the same proven procedures used for Soyuz vehicles at the Baikonur Cosmodrome in Kazakhstan and Plesetsk Cosmodrome in Russia.
The Spaceport’s assembly building is 92 meters long, 41 meters wide, and 22 meters tall. It is equipped with two traveling cranes for handling launcher segments, along with a rail system for the movement and integration of the stages.
Completed Soyuz vehicles depart the building on a transporter/erector rail car, which is rolled out to the launch pad for erection, payload integration, final checkout and launch. Situated behind the assembly building is a rear zone area which comprises the Soyuz launch site’s support facilities – including air conditioning and power systems, offices, telecommunications infrastructure and the launch control center.
The reinforced control center is the only building in the Soyuz launch zone that is occupied during final countdown and liftoff. This three-story facility houses the equipment, consoles and offices for the mission control team.
