In a significant advancement for maritime technology, Northrop Grumman’s Manta Ray Uncrewed Underwater Vehicle (UUV) has successfully completed full-scale, in-water testing. This series of tests, conducted off the coast of Southern California in early 2024, showcased the UUV’s hydrodynamic capabilities, including its diverse propulsion and steering mechanisms.

Modular Design for Rapid Deployment
The Manta Ray UUV, a DARPA-backed project, represents a breakthrough in modular underwater vehicle design. “The full-scale testing of the Manta Ray UUV marks a pivotal moment in underwater technology, confirming its operational readiness,” stated Dr. Kyle Woerner, DARPA’s program manager. The vehicle’s modular design allows for swift assembly and deployment, offering unprecedented flexibility for naval operations.
Efficient and Versatile
Transported in sections from Maryland to California, the Manta Ray’s design facilitates easy shipping and quick assembly, optimizing it for global deployment without the need for extensive naval facility space. “Direct shipping to operation zones conserves the vehicle’s energy, which is crucial for its long-range missions,” explained Woerner. The UUV employs buoyancy-driven gliding for efficient movement and is equipped with multiple payload bays to support a broad range of naval missions.
A New Class of UUVs
The Manta Ray project aims to introduce a new category of UUVs characterized by their long-duration, long-range capabilities, and payload capacity. These UUVs are designed to withstand the challenges of dynamic maritime environments and are poised for persistent operations. DARPA is currently coordinating with the U.S. Navy to plan further testing and integration of this innovative technology.
As the Manta Ray project progresses, PacMar Technologies continues to refine its energy harvesting system, ensuring that the future of underwater exploration and operation is both sustainable and efficient.
