https://www.darpa.mil/news-events/2024-05-01TheManta Rayprototype uncrewed underwater vehicle (UUV) built by performer Northrop Grumman completed full-scale, in-water testing off the coast of Southern California in February and March 2024. Testing demonstrated at-sea hydrodynamic performance, including submerged operations using all the vehicle’s modes of propulsion and steering: buoyancy, propellers, and control surfaces.
“Our successful, full-scale Manta Ray testing validates the vehicle’s readiness to advance toward real-world operations after being rapidly assembled in the field from modular subsections,” saidDr. Kyle Woerner, DARPA program manager for Manta Ray. “The combination of cross-country modular transportation, in-field assembly, and subsequent deployment demonstrates a first-of-kind capability for an extra-large UUV.”

Manta Ray aims to develop and demonstrate a new class of long-duration, long-range, payload-capable UUVs ready for persistent operations in dynamic maritime environments. DARPA is engaging with the U.S. Navy on the next steps for testing and transition of this technology.
A second Manta Ray performer, PacMar Technologies, is continuing testing of its full-scale energy harvesting system in 2024.
