DARPA has successfully completed the first in-water testing of the Manta Ray uncrewed underwater vehicle (UUV) prototype, developed by Northrop Grumman.
Under the Manta Ray program, US research agency DARPA aimed to develop a completely new class of uncrewed underwater vehicles (UUVs), drawing inspiration from the massive "winged".
Northrop Grumman Corporation has built its Manta Ray uncrewed underwater vehicle, which will operate long-duration missions and carry payloads into the ocean depths in partnership with DARPA.
