Le prototype du véhicule sous-marin non habité Manta Ray (UUV) construit par Northrop Grumman a terminé des tests à grande échelle dans l’eau au large de la côte sud de la Californie en février et mars 2024.

Les tests ont démontré des performances hydrodynamiques en mer, y compris des opérations sous-marines utilisant tous les modes de propulsion et de direction du véhicule : flottabilité, hélices et surfaces de contrôle.

“Notre test réussi à grande échelle de Manta Ray valide la préparation du véhicule à passer à des opérations réelles après avoir été rapidement assemblé sur le terrain à partir de sous-sections modulaires”, a déclaré le Dr Kyle Woerner, directeur du programme DARPA Manta Ray. “La combinaison de transport modulaire entre les pays, l’assemblage sur le terrain et le déploiement ultérieur démontre une capacité sans précédent pour un UUV extragrand.”

Northrop Grumman a expédié le prototype Manta Ray en sous-sections du site de construction dans le Maryland à son site de test en Californie. La facilité de transport et d’assemblage démontrée soutient la possibilité de déploiement rapide dans le monde entier sans occuper un espace précieux sur le quai des installations navales.

“L’expédition du véhicule directement dans la zone opérationnelle souhaitée conserve l’énergie que le véhicule dépenserait autrement pendant le transit”, a déclaré Woerner. “Une fois déployé, le véhicule utilise un glissement efficace et propulsé par la flottabilité pour se déplacer dans l’eau. L’embarcation est conçue avec de multiples compartiments de charge utile de différentes tailles et types pour permettre une large gamme de missions navales.”

Manta Ray vise à développer et à démontrer une nouvelle classe de UUV à longue durée, à longue portée et à capacité de charge utile, prêts pour des opérations persistantes dans des environnements maritimes dynamiques. La DARPA collabore avec la Marine américaine sur les prochaines étapes pour les tests et la transition de cette technologie.
