Ariane Final Assembly Building (French Guiana)

Weather…

The Bâtiment d'Assemblage Final (BAF) is a prominent building within the Guiana Space Centre near Kourou, specifically designed for the final assembly of Ariane 5 rockets. Standing approximately 90 meters tall, it allows for the vertical integration of the launcher with its payload under cleanroom conditions. Inside this facility, satellites were mounted onto the adapter and finally placed under the protective fairing atop the rocket. The BAF is part of a highly complex logistical system that includes the transfer of the rocket on rails to the launch pad. Following the retirement of the Ariane 5, the building is being adapted for future generations of launch systems or preserved as part of the historical infrastructure of the European spaceport. The architecture of the BAF is designed to withstand extreme climatic conditions, such as high humidity and potential tropical storms, while high-precision technical work is conducted on spacecraft indoors.
