Manta Ray

Uncrewed support for long-duration undersea missions, going where humans can’t.

Extending Undersea Excellence

Northrop Grumman has been pioneering capabilities in the undersea domain for more than 50 years. Now, we are creating a new class of uncrewed underwater vehicles (UUV) with Manta Ray. Taking its name from the massive “winged” fish, Manta Ray will operate long-duration, long-range missions in ocean environments where humans can’t go.

Advancing UUV Technology

We developed our unique full-scale demonstration vehicle using several novel design attributes that support the Defense Advanced Research Projects Agency’s (DARPA’s) vision of providing ground-breaking technology to create strategic surprise. Manta Ray is:

  • Payload-capable to support a variety of missions
  • Autonomous, without the need for on-site human logistics
  • Energy-saving, with the ability to anchor to the seafloor and hibernate in a low-power state
  • Modular, for easy shipment in five standard shipping containers to support expeditionary deployment and in-field assembly world-wide
