A facility unique in France and Europe, the air-sea experimental tank is located at ENSTA’s Brest campus. It consists of a large basin and a covered aviary, equipped with comprehensive satellite coverage, to test—under controlled, real-world conditions—the cooperation between tomorrow’s autonomous drones and mobile observation systems by combining aerial, surface, and underwater technologies.

An exceptional scientific facility to accelerate maritime innovation

Inaugurated on June 24, 2026, ENSTA’s large air-sea test basin​ is unique in France and Europe.​

  • ​A wide and deep basin ​20 m long x 12 m wide​ x 6 m deep​
  • topped by a 5-meter-high drone aviary​
  • under a shelter, and equipped with full GPS coverage, to conduct tests under controlled, real-world conditions​
  • in the immediate vicinity of the research laboratories, at the heart of a scientific and industrial environment of excellence in marine engineering.

Equipment:

  • a removable bottom covering one-quarter of the basin to reduce its depth
  • an overhead crane for launching heavy loads (large prototypes)
  • a mobile access walkway providing access to all points of the basin
  • a motorized roller shutter that covers the basin and allows tests to be conducted exclusively in aviary mode.

This scientific facility strengthens national and European capabilities for observing and understanding the ocean.

The basin enables testing, in a controlled experimental environment, of the coordination between drones and marine observation systems, combining aerial, surface, and underwater technologies. It offers opportunities for testing prior to at-sea deployments under real-world conditions, thereby serving as a major driver for accelerating innovation for industry and all maritime stakeholders.
