The SIAE—short for Salon International de l’Aéronautique et de l’Espace—is one of the world’s most prestigious and historic aerospace exhibitions. Held every two years at Le Bourget Airport near Paris, the show has been the beating heart of global aviation and space innovation since its inception in 1909.

Spanning civil, military, and space sectors, the SIAE brings together over 2,500 exhibitors from nearly 50 countries, showcasing everything from fighter jets and commercial aircraft to satellite systems and next-gen propulsion tech. It’s a launchpad for major industry announcements, contract signings, and dazzling aerial demonstrations that draw hundreds of thousands of professionals and enthusiasts alike.

Beyond the spectacle, the SIAE is a strategic hub—where governments, startups, and aerospace giants converge to shape the future of flight, sustainability, and defense. With dedicated programs like Start Me Up for emerging innovators and Women in Aerospace for inclusive leadership, the show is as much about who’s building the future as it is about what’s being built.
