On June 24, 2026, ENSTA, a founding member of the Institut Polytechnique de Paris, inaugurated a unique air-sea experimental tank on its Brest campus. Particularly innovative in its design, it allows for the testing of cooperation between drones and marine observation systems, while eliminating the risks inherent to initial trials on the high seas. Co-funded by the State and local authorities, the facility addresses academic, industrial, civil, and national defense needs, as well as national sovereignty challenges.
