The uncrewed underwater vehicle (UUV) prototype was built through a programme by the Defense Advanced Research Project Agency (DARPA) and assembled in Northrop Grumman’s Annapolis facility.
A prototype of a Manta Ray-class vessel, part of a new class of UUVs developed to be energy-saving and able to anchor at the seafloor to rest in a low-power state, has been unveiled by Northrop Grumman.
According to the US defence company, the extra-large glider will be able to carry out tasks for long durations and ranges, as well as be equipped for payload-capable undersea missions.
DARPA stated that the UUV would be built as part of the US government agency’s Manta Ray programme, which has been exploring uncrewed systems that could enable traditional host vessels to operate with more flexibility and freedom.

The project has included at-sea demonstrations and multiple phases while developing UUVs that remain independent of manned vessels and ports.
In 2020, DARPA approached Lockheed Martin to design an extra-large UUV powered by innovative energy management techniques for the Manta Ray project.
In 2021, DARPA awarded Phase 2 agreements to continue the Manta Ray programme to two prime contractors, Northrop Grumman Systems Corporation and Martin Defense Group, renamed PacMar Technologies. Each company was tasked with building and testing unique full-scale demonstration systems.
According to DARPA, PacMar conducted an in-water splash test with its prototype in 2023, testing the glider’s sensors, hydrodynamic performance and autonomy behaviour.
