In defense, innovation is key. Whether on land or at sea, technologies are constantly evolving across the world to offer increasingly efficient tools to the armies of different States. In this context, the French company Naval Group presented, during the Naval Group Innovation Days on October 7, technologies that could equip the French Navy within a few years, details BFMTV. New in this arsenal: aerial drones capable of exploring the seabed.

These devices could indeed be propelled underwater from submersibles to protect, attack or carry out intelligence missions. “It is not a question of replacing what exists and even less of sailors or submariners, but of offering navies the means to increase their operational reach and to face new threats wherever they are. they come “, details to the news channel the CEO of Naval Group, Pierre Éric Pommellet.

Thus, the drones offered by Naval Group could be capable of neutralizing or carrying out an attack at sea. Another prototype was particularly noticed during the Naval Group Innovation Days: a large oceanic underwater drone, developed in partnership with Thales and the start -up Delfox, details Le Figaro. The machine is thus able to reconfigure its mission and its trajectory according to the conditions encountered underwater. A first demonstrator, 10 tonnes and 10 meters long, was thus tested in February 2021.

This innovation could prove to be invaluable for the navies of the world, while a first autonomous surveillance test mission is scheduled for 2022. Indeed, the underwater drone could be capable of carrying out missions of several thousand kilometers during several weeks, in complete autonomy. If the tests are conclusive, the first aircraft could equip the French Navy by 2025.

Autonomous submarine devices are particularly difficult to develop, recalls BFMTV, because of the exceptional conditions in which they operate. “The main difficulty lies in communication, explains Éric Papin, technical and innovation director of Naval Group. Underwater, remote piloting and the transmission of information are much more complicated than on the surface”.
