DARPA Manta Ray Uncrewed Underwater Vehicle Testing
Northrop Grumman and DARPA’s Manta Ray uncrewed underwater vehicle (UUV) goes beneath the surface during its latest test. Its unique size and shape enables the drone to save power and energy for long missions.



Thanks to the Manta Ray’s modular design, it can disassembled into separate parts for easy shipping and then assembled in-field. With missions around the world, Manta Ray allows US military forces to bring critical capabilities wherever they are needed. The tests demonstrated its ability to glide, ascend and descend, turn, hover and anchor, with some of these skills being completed autonomously.

DARPA Manta Ray Uncrewed Underwater Vehicle Testing

Our team had to be creative and innovative to find solutions that would work for a glider UUV as big as Manta Ray. It’s not a one-to-one scale with typical glider UUVs; because of its size, we added more buoyancy engines, a bigger payload bay, an enhanced towing system and an extremely efficient and large hull system,” said Hayley Sypniewski, Structural Engineer.
