The Soyuz launch site is located in the northwest part of the Guiana Space Centre (CSG).

It consists of three main zones: the launch platform, made up of a five-level reinforced concrete structure, the preparation area, where the three stages are assembled horizontally and checked, and the launch control centre.

The Soyuz performance perfectly complements that of the Ariane and Vega launchers, and increase the competitiveness and flexibility of the exploitation of Ariane in the commercial market.
